AI PIXELL Terms of Service

Effective date · June 29, 2026

These Terms of Service (these “Terms”) constitute a legally binding agreement entered into between 4BY4 Co., Ltd. (the “Company”) and the User. These Terms apply to all of the following services provided by the Company under the AI PIXELL brand (collectively, the “Service” or “PIXELL”):

AI PIXELL Desktop Client: the desktop-installable application provided at aipixell.com;
PIXELL Detailer: the SaaS-type image/video quality-enhancement service provided at detailer.aipixell.com;
AI PIXELL API and on-premises software; and
any other websites, mobile apps, applications, features, and services provided by the Company under the AI PIXELL brand.

In these Terms, “PIXELL” or the “Service” means all of the AI PIXELL services described above. An account created by the User in any one of the services is a single, integrated account that applies commonly across the entire Service (registering through one service allows the User to log in to and use the other services with the same account).

With respect to the installation, execution, licensing, device activation, automatic updates, local processing, and similar matters of the AI PIXELL Desktop Client, the “AI PIXELL Desktop Client End User License Agreement” (the “Desktop EULA”) applies together with these Terms. To the extent that these Terms and the Desktop EULA conflict as to the use of the Desktop Client, the Desktop EULA prevails to that extent, and these Terms apply to all other matters.

If the User uses the Service, the User is deemed to have agreed to these Terms. Where the User is deemed to have agreed, or uses the Service after agreeing to these Terms, the User is responsible for complying with applicable laws and regulations. If the User does not agree to these Terms, the User may not use the Service or access the Service’s websites.

The Company may change or supplement these Terms as necessary and in accordance with applicable law. Amended Terms are notified or announced to the User by an appropriate method, such as posting a link on the initial screen of the Service homepage in accordance with applicable law or requesting the User’s consent. If the User continues to use the Service after the amended Terms have been posted, the User is deemed to have agreed to the most recent Terms in effect at that time. If the User does not agree to the amended Terms, the User must discontinue use of the Service. Amended Terms take effect upon posting or on the separate effective date specified in the amended Terms, and apply to the User’s use of the Service from that point onward.

The Company reserves the right to change or discontinue all or part of the Service. Descriptions of the services provided by the Company do not mean that such services will always be provided identically, and the Company continuously improves and updates the Service.

Article 1 (Eligibility Requirements and User Accounts)

Age Requirement. The User must be at least 14 years of age to register a PIXELL account and use the Service. By using the Service, the User warrants that it meets the age requirement set forth in these Terms. Where a minor User under the age of 14 wishes to register as a member, an additional consent procedure by a legal representative, such as a parent, is required.

Legal Capacity. The User must have the capacity to enter into a legally binding agreement with the Company. When the User uses PIXELL, the User warrants that it has the authority and capacity to comply with these Terms.

Compliance with Laws. The User must use PIXELL in a manner that complies with all applicable laws and regulations of the jurisdiction of its residence. Where the User accesses PIXELL from a location outside the Republic of Korea, the User is responsible for compliance with the laws of that location.

Persons Subject to Use Restrictions. Any person who has previously been prohibited from using the Service or whose membership has been terminated by the Company may not use PIXELL. Use is also restricted where use of the Service is deemed unlawful in the relevant jurisdiction.

Article 2 (Account Registration and Security)

The User may create only one account to use the Service. The User may not create two or more accounts or share an account with others. The Service operates as a single, integrated account, and an account created in one service may be used for the other services as well.

All information provided when creating an account must be accurate and complete, and the User may not misappropriate another person’s name or use a name that is not its own. The User warrants that it will use the Service only in a manner that complies with applicable laws and regulations. The User is also responsible for keeping its account information up to date at all times.

The User is solely responsible for maintaining the confidentiality of its account information and is responsible for all activity under its account. The User must not use another user’s account, ID, or password, or disclose its own password to any third party. The User may not sell, share, or transfer its account or membership rights.

If the User suspects unauthorized use of its account or a leak of its password, the User must immediately notify the Company.

Article 3 (Intellectual Property Rights)

Ownership of Content. Ownership of all content and materials provided on PIXELL — including text, graphics, logos, icons, images, audio and video clips, data compilations, and software (collectively, the “PIXELL Materials”) — belongs to the Company or its content providers and is protected by applicable intellectual property laws, including copyright, trademark, patent, and trade secret laws.

Trademarks. The PIXELL name and logo, and related names, logos, product and service names, designs, and slogans are trademarks of the Company or its affiliates and licensors. The User may not use them without the Company’s prior written consent. Other names, logos, product and service names, designs, and slogans displayed on this site are the trademarks of their respective owners.

Grant of License. Provided that the User complies with these Terms, the Company grants the User a limited, non-exclusive, non-transferable, and revocable license to access and use the PIXELL Service for personal and internal business purposes. This license does not include reselling or commercially exploiting the PIXELL Materials; collecting and using product listings, descriptions, or prices; creating derivative works; or collecting and extracting information through data mining, robots, automated tools, or the like.

Use Restrictions. The User may not engage in any of the following acts:

reproducing, distributing, modifying, creating derivative works of, publicly displaying, publicly performing, reposting, downloading, storing, or transmitting the PIXELL Materials; provided, however, that the following are exceptions: (i) automatic temporary storage to enhance personal display, such as web-browser caching, and (ii) downloading and storing some pages of the website within a reasonable scope for personal, non-commercial purposes;
arbitrarily modifying any copy of the PIXELL Materials;
using illustrations, photographs, video or audio sequences, or graphics of the PIXELL Materials separately from their accompanying text, or creating derivative works using the PIXELL Materials;
deleting or altering any copyright, trademark, or other proprietary notice of the PIXELL Materials;
using all or part of the PIXELL Service or Materials for commercial purposes (except where a separate agreement is reached, in which case such agreement governs).

User Content and Submissions. Content that the User uploads, posts, or submits to PIXELL (“User Content”) remains the property of the User and is treated as confidential material. The Company will not use, disclose, or share User Content for any purpose other than providing the PIXELL Service without the User’s express consent. The Company does not use User Content for promotional or marketing purposes and does not reproduce, distribute, display, or create derivative works of it without prior written consent. The Company takes reasonable measures to protect the confidentiality and integrity of User Content and may access it only where required to provide the Service, ensure compliance with these Terms, or comply with applicable law.

Reporting Intellectual Property Infringement. The Company respects the intellectual property rights of others, and the User must do likewise. If the User believes that copyright infringement has occurred, it must report it to the Company’s copyright agent, including the following information:

the signature (including an electronic signature) of the copyright owner or its agent;
a description of the work alleged to have been infringed;
the location within PIXELL where the infringement occurred (such as a URL);
the reporting party’s address, telephone number, and email address;
a good-faith statement that the use is not authorized by the copyright owner, its agent, or the law; and
a statement, made under oath, that the above information is accurate and that the reporting party is the copyright owner or its agent.

Measures upon Infringement. The Company may terminate the accounts of repeat infringers where appropriate.

Article 4 (License to Use)

Actual use of individual service features — such as video processing, API calls, enhancement, and upscaling — is enabled through Credits paid under Article 5 (Pricing Plans and Payment Policy), and the User is granted a separate right of use to access such features within the scope of the Credits granted or purchased.

Use of the Desktop Client. The installation, execution, and grant and restriction of licenses for the AI PIXELL Desktop Client are governed by the Desktop EULA and are regulated separately from the provisions of this Article concerning SaaS, API, and on-premises software. The Desktop Client is used under a license pursuant to the Desktop EULA (perpetual, subscription, free trial, etc.) rather than through Credits.

Grant of License. Provided that the User complies with these Terms and has paid the fees required to use the relevant service, the Company grants the User the following limited, non-exclusive, and non-transferable license:

the right to access and use the PIXELL SaaS platform through a web browser or supported device;
the right to access and use the PIXELL API to integrate video quality-enhancement features into the User’s own applications, within the scope of the selected API usage plan; and
the right to install and use the PIXELL on-premises software on a local server, in accordance with the license terms specified at the time of purchase.

Use Restrictions. The User may not engage in any of the following acts:

tampering with or modifying, or reverse-engineering, decompiling, or disassembling, all or part of the PIXELL SaaS platform, API, or on-premises software;
renting, leasing, selling, redistributing, or sublicensing the PIXELL software or Service;
using PIXELL in a manner that impairs, disables, overburdens, or interferes with the functioning of the Service, or that hinders other users’ use of the Service; or
circumventing, or attempting to circumvent, any limit imposed on the account (such as API usage limits).

Use of SaaS and API. The User’s use of the PIXELL SaaS platform and API is subject to the limits set forth in the usage-license policy for each service. The usage-license policy for each product is posted on the homepage of the respective service. Such limits may include the number of API calls, storage capacity, and processing performance. Exceeding the limits may result in additional charges or suspension of use of the Service.

Purchase of License. Matters concerning the purchase, grant, use, expiration, and refund of the Credits required to use the video processing features are governed by Article 5 (Pricing Plans and Payment Policy).

Use of On-Premises Software. The PIXELL on-premises software may be used only within the number of servers and users specified in the license agreement. Unauthorized use exceeding the permitted scope is strictly prohibited and may constitute grounds for license termination.

Term and Termination. The license granted under these Terms remains valid until terminated. The User may terminate the license at any time by discontinuing use of PIXELL and deleting the on-premises software. The Company may terminate the license if the User breaches these Terms or if the subscription expires or is cancelled, in which case the User must immediately discontinue use of PIXELL and delete all copies of the software.

Updates and Upgrades. The Company may update or upgrade the PIXELL software or Service. Some updates or upgrades may be provided automatically or may require manual installation by the User. These Terms apply equally to updates and upgrades, and where a separate license (such as the Desktop EULA) accompanies them, the terms of that license apply with priority.

Support Services. Technical support for the PIXELL SaaS, API, and on-premises services may be provided depending on the subscription plan and may include support for installation, use, troubleshooting, and updates. The scope of available support and response times may vary depending on the subscription level.

Ownership. All rights, title, and interest in and to the PIXELL SaaS platform, API, on-premises software, and related intellectual property rights belong to the Company, and no ownership is transferred to the User.

Article 5 (Pricing Plans and Payment Policy)

The provisions of this Article concerning pricing plans, Credits, payment, and refunds apply to PIXELL Detailer (SaaS) and Credit-based services. Payment and refunds for perpetual and subscription licenses of the AI PIXELL Desktop Client are governed by the payment and refund policy of the Desktop EULA (including a 30-day full refund for installed-type licenses).

Plan Composition. For use of the PIXELL Service, the Company offers monthly subscription plans such as Free, Lite, Pro, and Max, as well as individual Credit top-up products (collectively, “Plan Products”). The Credits provided, prices, number of models that can run concurrently, task priority, and other service limits for each Plan Product are posted on the Service homepage, and the Company may change them as necessary.

Grant and Validity Period of Credits — Definition of Credits. Credits mean a right of use to use PIXELL’s video processing service that is provided solely for the User’s convenience upon the conclusion of a Plan Product transaction between the Company and the User. Credits may not be used for any goods or services other than use of the Service, as a prepaid electronic payment instrument would be, and are not a stored means of monetary value subject to a refund obligation.

Credits held by the User grant the right to request the relevant service feature. If Credits are exhausted or insufficient, all or part of the relevant service may become unavailable.
Credits are attributed to the account and may not be transferred, sold, or lent to others.

Paid Subscription Plans. Upon completion of payment for a paid plan, the Credits for that plan are granted immediately, and the validity period of the granted Credits (the “validity period” means the contractual period upon the lapse of which the right to use the service corresponding to such Credits terminates; expiration of the validity period constitutes a condition of termination of the service-use contract effected by such Credits, independently of whether the Credits have been exhausted through use; in principle, the validity period cannot be extended except where attributable to the Company, such as a service outage; the same applies hereinafter) is 30 days (720 hours) from the payment date.

The price, composition, and other conditions of the plan are subject to the terms set forth on the respective purchase page.
Credits not used within the validity period automatically lapse immediately upon expiration and are not refunded or compensated.

Free Plan.

A new member’s Free plan begins immediately upon registration, and 10 Credits are granted at the time of registration.
Free plan users, including existing members, are automatically granted 10 Credits at midnight on the first day of each month.
Free Credits automatically lapse in full upon expiration of their validity period at 23:59 on the last day of each month and are not refunded or compensated.
The Free plan is not subject to separate cancellation or subscription cancellation, and the User may terminate the Free plan by withdrawing its membership.

Individual Top-Up Credits.

The User may purchase and top up additional Credits as needed.
The validity period of topped-up Credits is 30 days (720 hours) from the payment date.
The price, composition, and other conditions of the plan are subject to the terms set forth on the respective purchase page.
Credits not used within the validity period automatically lapse immediately upon expiration and are not refunded or compensated.

Method of Use and Deduction of Credits.

Credits are automatically deducted in the order in which their validity period expires soonest.
The Credits required when requesting a video processing task are calculated as follows: the video length is rounded up to the nearest minute (rounding up the seconds), and the required Credits = “rounded-up video length (minutes)” × “Credit consumption per minute for the relevant model.”
Credits are deducted simultaneously with the task request, and if a task fails, the deducted Credits are immediately restored.
The Company may determine whether a task has succeeded or failed according to its own criteria, and the success criteria are based on system logs and processing results.
The calculation of video length and the basis for Credit deduction follow the logs and internal calculation method of the Company’s system, and the User agrees thereto.

Subscription Renewal and Automatic Payment Policy.

Paid plans operate on a recurring-payment basis and are automatically renewed and charged each billing cycle unless the User cancels.
The Company clearly notifies the User in advance of essential information such as the automatic payment amount, payment date, and renewal cycle.
Automatic payment is first attempted two days (48 hours) before the scheduled renewal date of the relevant plan, and if the first payment attempt fails, the Company may, in accordance with its internal policy, retry payment up to three times. The retry intervals are 1 hour, 24 hours, and 48 hours, respectively, from the time of the first failure.
If all payment retries fail, the paid plan terminates on the expiration date and the User is automatically switched to the Free plan.
If the User cancels the renewal at least two days (48 hours) before the scheduled renewal date of the plan, the next cycle’s fee is not charged and the User is switched to the Free plan.
The method for cancelling automatic payment is provided through the in-service payment settings screen, and the User may cancel automatic payment at any time.

Plan Changes.

The User may change to a higher or lower plan at any time, and the change takes effect from the time payment is completed.
Upon a change, the Credits for the new plan are granted immediately, and previously held Credits are carried over while retaining the validity period for each type.
No difference is refunded upon an upgrade or downgrade of the plan.
Where the User has been refunded for a paid plan in use and is immediately switched to the Free plan, no Free Credits are granted at the time of the change; thereafter, Free Credits are granted on the first day of each month.

Policy Applicable upon a Change in Plan Prices.

The Company may change the price of a plan (the “Plan Price”) as necessary for the operation of the Service, and when the price changes, the Company provides advance notice in accordance with applicable law.
A member who has been subscribing to a paid plan from before the price change will, if it continues the plan without cancelling it, have automatic payment processed at the previously charged amount (the amount before the price change).
If a member cancels its subscription to a paid plan after the price change and then subscribes to the same plan again, it is charged at the changed price applicable at that time.
Even where a member changes to a higher or lower plan, the new plan after the change is charged at the latest price applicable at the time of the plan change.
The Company clearly notifies the effective date of the price change, the details of the change, and the basis for application through service notices, email, or other electronic means.
To prevent errors or improper application, the Company may automatically verify past subscription price changes and, if an abnormal payment amount is found, retroactively adjust it and additionally charge the User.

Subscription Cancellation and Plan Termination.

If the User ends its subscription to a paid plan or terminates the plan, the benefits of the existing plan are maintained as-is until the end of the validity period of the current cycle.
From the next recurring-payment date, the User is automatically switched to the Free plan, and the Free plan policy applies from the time of such switch.
The Free plan cannot be cancelled.

Full Refund Policy (Credit-Based Services). Where the provision of digital content has commenced, the withdrawal of subscription is restricted under Article 17(2) of the Act on the Consumer Protection in Electronic Commerce. However, the Company provides refunds for unused Credits only, in accordance with its own refund policy. Where both of the following conditions are satisfied, the User may request a full refund by withdrawal of subscription within 7 days from the payment date:

7 days have not elapsed from the payment date; and
there is no usage history whatsoever of the Credits granted under the relevant plan.

Where even a single Credit has been used, or where 7 days have elapsed, a partial refund is provided and the refund amount is calculated in accordance with the policy. When a refund is completed, the User is immediately switched to the Free plan; however, if there is another paid plan that was paid for before the refund request and still has a remaining validity period, the service benefits of that plan are maintained for the duration of its validity period. When a refund is completed, all granted paid Credits and benefits lapse. Top-up Credits may also be fully refunded under the same criteria (within 7 days, if unused). Where the User has been restricted from use by the Company for violating Article 1.4, Article 2.1 or 2.3, Article 3.4, or Article 4.2 of these Terms, the User may not demand a refund or the like from the Company.

Partial Refund Policy (Credit-Based Services). Where the User requests a partial refund for a paid plan, the Company calculates the refund amount according to the following criteria:

The refund reference date is the date on which the User submits the refund request through the refund-intake page provided by the Company.
Unused Credit value = (remaining Credits ÷ total granted Credits) × payment amount.
Cancellation fee = unused Credit value × 15%.
Refund amount = unused Credit value − cancellation fee (the final refund amount is calculated by truncating amounts below the won unit).

Where the User has no unused Credits — for example, because all Credits have been used or the Credits have lapsed due to expiration of the validity period as of the refund reference date — no refund is provided; and where the User uses Credits after submitting a refund request, the refund request is deemed withdrawn. When a refund is completed, the User is immediately switched to the Free plan; however, if there is another paid plan that was paid for before the refund request and still has a remaining validity period, the service benefits of that plan are maintained for the duration of its validity period. After the refund, all granted paid Credits and benefits lapse.

Payment and Refund of Desktop Licenses. The payment, refund, and withdrawal of subscription for perpetual and subscription licenses of the AI PIXELL Desktop Client are governed not by the Credit refund policy of this Article but by the payment and refund policy of the Desktop EULA (for example, a 30-day full refund from the payment date, provision of a trial through a free trial, etc.). Where this Article and the Desktop EULA conflict, the Desktop EULA prevails with respect to desktop licenses.

Data Retention and Deletion.

The period during which video processing results can be downloaded is 10 days from the completion date, and they are automatically deleted upon the lapse of that period. Deleted results cannot be recovered.
Where integration with an external platform (such as YouTube) is provided, certain features may not be available after 9 days from the completion date, in accordance with the policy of that platform.
The Company may change the data retention period and deletion policy and will provide advance notice of any change.

Price and Policy Changes.

The Company may change plan prices, Credits provided, payment policies, and the like, and will provide advance notice of changes through the Service homepage or electronic notification.
For changes that include a price increase, the Company notifies the User at least 7 days in advance.
Changed policies apply, from the notified effective date, to newly paid or renewed plans.

External Payment Services. The Company may entrust part of payment processing to an external payment agent, and errors, approval delays, card-company policies, and the like that arise during the payment process are subject to the regulations of that agent. The Company is not liable for any damage caused by a failure of an external payment service.

Article 6 (User Content)

This Article applies primarily to SaaS and cloud services that upload and process User Content to the Company’s servers. The AI PIXELL Desktop Client processes User Content locally within the User’s device in accordance with the Desktop EULA and does not upload it externally.

Ownership. The rights to images, videos, and other content that the User uploads to PIXELL (“User Content”) belong entirely to the User, and the Company does not claim any ownership thereof.

Confidentiality and Privacy Protection. The Company understands that User Content may be confidential and does its best to protect the User’s content. User Content is used solely for the purpose of providing the Service (such as processing and enhancing the quality of uploaded files).

Prohibition of Use Without Consent. The Company does not access, distribute, or share User Content without the User’s express written consent, nor does it use it for promotional or marketing purposes. Reproduction, distribution, display, or creation of derivative works of User Content is not carried out without the User’s prior consent.

Grant of Processing Rights. Where the User uploads content to PIXELL, the Company holds a limited, non-exclusive, and revocable license to process, store, and enhance the quality of such content within the scope necessary to provide the Service. This license is limited solely to the purpose of operating PIXELL and does not grant the Company any other rights.

User Responsibility. The User bears full responsibility for the User Content it uploads. The User warrants that it holds lawful rights and authority over such content and that the Company’s use of the content in accordance with these Terms does not infringe any third party’s intellectual property rights, personal information, or contractual rights.

Content Deletion. The User may delete its content from the PIXELL platform at any time. Upon deletion, the Company no longer retains such content stored on its servers; provided, however, that it may exceptionally retain it for a certain period where necessary to comply with applicable law or for backup or legitimate business purposes.

Restriction of Inappropriate Content. The User may not upload content that is illegal, harmful, defamatory, obscene, or otherwise inappropriate. The Company reserves the right, at its sole discretion, to review, monitor, and delete User Content that violates these Terms; this is a discretionary matter and not an obligation.

Backup Responsibility. The Company makes reasonable efforts to protect the security and integrity of User Content but is not liable for any loss or damage during the upload, processing, or download process. The User is responsible for maintaining backups of its original files.

Handling upon Account Termination. If the User’s account is terminated for any reason, the right to access User Content stored under that account is extinguished. The User must back up important data in advance, before account termination or suspension.

Indemnification. The User agrees to indemnify and hold harmless the Company and its officers and employees from and against all claims, losses, damages, and costs (including reasonable attorneys’ fees) arising in connection with its User Content.

Article 7 (Copyright Infringement)

Respect for Copyright. The Company respects the intellectual property rights of others, and the User must not infringe the intellectual property rights of others, including copyrights, in using the PIXELL platform. The User must hold the necessary rights and usage authority for all content it uploads, shares, or processes on PIXELL.

Copyright Infringement Reporting Procedure. If the User believes that its own work has been used in a manner that constitutes copyright infringement, it must submit a notice to the Company’s designated copyright agent including the following:

a physical or electronic signature signed by the copyright owner or its authorized agent;
a description of the work alleged to have been infringed (a representative list is acceptable where there are multiple works);
the location within PIXELL where the infringement occurred (for example, a specific URL or file name);
the reporting party’s address, telephone number, and email address;
a good-faith statement that the use is not authorized by the copyright owner, its agent, or the law; and
a statement, made under oath, that the contents of the notice are accurate and that the reporting party is the copyright owner or its authorized agent.

Company Measures. Upon receipt of a valid copyright infringement report, the Company may take appropriate measures, which may include: deleting or blocking access to the relevant content; notifying the relevant user of the infringement; and terminating the account of a user confirmed to be a repeat infringer.

Counter-Notice. If the User’s content has been deleted due to a copyright infringement claim but the User believes that the deletion was erroneous or that it holds legitimate rights, it may submit a counter-notice to the Company’s designated copyright agent. The counter-notice must include the following:

the User’s own signature (physical or electronic);
a description of the deleted or blocked content and its location;
a good-faith statement that the content was deleted erroneously or as a result of a mistake (including a declaration accepting the penalties for perjury); and
the User’s name, address, and telephone number, together with a statement consenting to the jurisdiction of the competent court and accepting service from the original reporting party or its agent.

Handling of Repeat Infringers. Where infringing activity by the same user is confirmed two or more times, or content is deleted two or more times, the Company may deem that user a repeat infringer and terminate its account.

Legal Liability for False Reports. A party that knowingly makes a false copyright infringement report may be subject to legal liability and may bear damages, litigation costs, and attorneys’ fees.

Article 8 (Account Termination)

Voluntary Account Termination. The User may terminate its PIXELL account at any time by following the procedure provided in the account settings. Upon account termination, the right to use the services provided by PIXELL ends, and content stored on the platform may be permanently deleted in accordance with these Terms and the relevant data retention policy.

Effect of Account Termination. Because the account is a single, integrated account, upon account termination the right to use the entire Service — including the AI PIXELL Desktop Client and PIXELL Detailer — ends together. Upon account termination, the following measures apply immediately:

Termination of Access: the right to access all services and features associated with the account (including ongoing projects, stored content, and service-related information) is extinguished.
Data Deletion: User Content associated with the account is deleted from the servers; provided, however, that it may exceptionally be retained for a certain period where necessary to comply with applicable law or for backup or legitimate business purposes.
Subscription Fees: no additional fees are charged after the account termination date, but fees already paid are not refunded except as provided by law (refunds of desktop licenses are governed by the Desktop EULA).
Outstanding Fees: any outstanding fees or balances incurred before account termination must be settled, and the Company may charge such amounts even after termination.

Involuntary Account Termination. The Company may suspend or terminate an account, with or without prior notice, where any of the following grounds exist: violation of these Terms; unlawful acts or acts that damage the reputation of PIXELL or the Company; non-payment of account-related fees; or repeated copyright infringement or intellectual property infringement.

Access Restriction After Account Termination. After an account is terminated, voluntarily or involuntarily, the User cannot access the PIXELL Service and can no longer access the User Content and projects stored under the account. The User must back up any necessary data before account termination.

Account Restoration. The Company may, upon the User’s request and where necessary, restore a terminated account, and whether to do so is determined at the Company’s discretion. A restoration fee may be charged in such cases.

Survival of Terms. Provisions that by their nature must survive account termination — such as those concerning intellectual property rights, confidentiality, disclaimers, and indemnification — continue to be valid after account termination.

Other Harmful Acts: acts that the Company determines may harm PIXELL, users, or the Company’s operations.

Enforcement Measures. If the User commits a prohibited act, the Company may take measures (the “Measures”) such as suspension of use of the Service, withdrawal of membership, or restriction on re-registration, without prior notice. Where urgently necessary, the Measures may be taken before notice.

Objection Procedure. The User may object to the Measures by submitting relevant materials, and the Company, after reviewing them, notifies the User whether the Measures will be maintained.

Information Retention. Where the User’s membership has been withdrawn, the Company may retain information in accordance with applicable laws and the Privacy Policy, and may maintain user information to the extent necessary to prevent re-registration.

Article 13 (Warranties and Disclaimers)

Disclaimer as to Service Availability. The Company does not warrant that the PIXELL platform will always be available or will be provided without errors, interruptions, or delays. The Service is provided “as is” and “as available,” and the Company does not guarantee that defects or errors will be corrected or that viruses and other harmful elements will be completely eliminated.

Disclaimer as to Content. The Company makes no warranty as to the accuracy, completeness, reliability, or quality of any content (including User Content) provided or accessible through PIXELL. The User must use such content at its own responsibility.

Disclaimer as to Results. While the Company aims to provide accurate, high-quality results in providing the video quality-enhancement service, it does not warrant that the results of using PIXELL will necessarily meet the User’s expectations or requirements. Service performance and results may vary depending on the characteristics of the content and the usage environment.

Third-Party Links and Services. PIXELL may contain links to third-party websites or services that the Company does not own or control, and the Company bears no responsibility for them. The User uses such third-party services at its own risk and must review the relevant terms and privacy policies.

Exclusion of General Warranties. To the maximum extent permitted by applicable law, the Company disclaims all express, implied, and statutory warranties, including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. The Company does not warrant that PIXELL will meet the User’s requirements, that the Service will be uninterrupted and error-free, or that defects will be corrected.

Limitation of Liability. In no event shall the Company or its officers, employees, agents, affiliates, or licensors be liable for any indirect, incidental, special, consequential, or punitive damages (such as loss of profits, loss of data, inability to use, or other intangible losses). This applies equally even if the Company was advised in advance of the possibility of such damages.

Disclaimer as to User Content. The User acknowledges that the Company is not liable for content uploaded or shared by the User or others through PIXELL, and must exercise reasonable care when interacting with other users or viewing content.

Absence of Professional Advice. All information, advice, and recommendations provided by the Company through the PIXELL platform or other means are for general reference only and do not constitute professional advice, and the User must obtain separate professional advice where necessary.

Exceptions to Limitations of Warranty and Liability. Some jurisdictions may not allow certain warranty exclusions or limitations of liability for incidental or consequential damages. In such cases, the limitations set forth in this Article apply to the maximum extent permitted by applicable law.

Article 14 (Indemnification and Hold Harmless)

User’s Indemnification Obligation. The User agrees to indemnify, defend, and hold harmless the Company and its officers, employees, agents, affiliates, and licensors from and against all claims, liabilities, damages, losses, and costs (including reasonable attorneys’ fees) arising in connection with any of the following:

the use of the PIXELL platform and the services, content, and features provided through it;
a breach of these Terms or of the representations, warranties, or covenants contained herein;
a violation of applicable laws or regulations;
infringement of a third party’s intellectual property rights, personal information, or contractual rights; and
any claim related to content that the User has uploaded, posted, or transmitted to PIXELL.

Defense of Claims. Where such a claim is asserted against the Company or an indemnified party, the Company may assume sole defense and control of such claim, and the User must cooperate with the Company in conducting the defense. The User may not settle such a claim at its discretion without the Company’s prior written consent.

Notice of Claims. The Company will endeavor to reasonably notify the User promptly upon becoming aware of a claim, suit, or proceeding that gives rise to an indemnification obligation. However, the Company’s delayed notice does not release the User from its indemnification obligation where there is no material prejudice to the User’s ability to defend.

Liability After Account Termination. The User’s indemnification and hold-harmless obligations under this Article continue to survive after account termination or discontinuation of use of PIXELL.

Limitation of Liability of Indemnified Parties. In no event shall an indemnified party be liable to the User or a third party for any indirect, incidental, special, consequential, or punitive damages in connection with a claim under this Article.

Article 15 (Entire Agreement)

Complete Understanding. These Terms, the AI PIXELL Desktop EULA, the Company’s Privacy Policy, and other policies and agreements expressly referenced in these Terms constitute the entire agreement between the Company and the User regarding the User’s access to and use of PIXELL. They supersede all prior oral or written agreements, proposals, and understandings between the Company and the User in connection with these Terms; provided, however, that where a separate agreement is reached, such as on a purchase page, such agreement prevails over these Terms.

No Reliance on External Statements. The User acknowledges that no rights or obligations arise from oral or written statements, warranties, or descriptions not set forth in these Terms.

Amendments and Changes. Any amendment or change to these Terms is made in writing and takes effect through a notice or consent procedure to the User in accordance with applicable law.

Severability. Even if any provision of these Terms is held by a competent court to be invalid, unlawful, or unenforceable, that provision will be enforced to the maximum extent permitted, and the remaining provisions will continue in full force and effect.

No Waiver. Even if the Company does not immediately enforce a particular right or provision, this is not deemed a waiver of that right or provision. Any waiver by the Company must be expressly made in writing and is not construed as a waiver of any other right or provision.

Article 16 (Governing Law and Dispute Resolution)

These Terms are interpreted and applied in accordance with the laws of the place where the Company’s head office is located or a separately designated jurisdiction.

All legal disputes arising in connection with these Terms are subject to the exclusive jurisdiction of the court having jurisdiction over the location of the Company’s head office. However, for consumers residing outside the Republic of Korea, the mandatory consumer protection laws and jurisdictional rules of their place of residence may apply in priority over this Article.

The Company and the User may resolve disputes through arbitration where necessary.
