Terms of Service

By downloading, installing, or using the LINEORA mobile application ("App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not install or use the App.

ZEITARC ("we", "our", or "us") operates this App from Islamabad, Pakistan. These Terms govern your use of the App and any in-app purchases made through it.

In the event of any conflict between these LINEORA Terms of Service and the Apple Standard EULA, the Apple Standard EULA shall take precedence. If you installed LINEORA from the Google Play Store, your use of the App is also governed by the Google Play Terms of Service (https://play.google.com/intl/en/about/play-terms/) and the Google Play Developer Distribution Agreement (https://play.google.com/about/developer-distribution-agreement.html); in the event of any conflict between these LINEORA Terms of Service and those Google terms, the Google terms shall take precedence with respect to the Google Play store relationship.

Appendix: Apple Licensed Application End User License Agreement

Apps made available through the App Store are licensed, not sold, to you. Your license to each App is subject to your prior acceptance of either this Licensed Application End User License Agreement ("Standard EULA"), or a custom end user license agreement between you and the Application Provider ("Custom EULA"), if one is provided. Your license to any Apple App under this Standard EULA or Custom EULA is granted by Apple, and your license to any Third Party App under this Standard EULA or Custom EULA is granted by the Application Provider of that Third Party App. Any App that is subject to this Standard EULA is referred to herein as the "Licensed Application." The Application Provider or Apple as applicable ("Licensor") reserves all rights in and to the Licensed Application not expressly granted to you under this Standard EULA.

a. Scope of License

Licensor grants to you a nontransferable license to use the Licensed Application on any Apple-branded products that you own or control and as permitted by the Usage Rules. The terms of this Standard EULA will govern any content, materials, or services accessible from or purchased within the Licensed Application as well as upgrades provided by Licensor that replace or supplement the original Licensed Application, unless such upgrade is accompanied by a Custom EULA. Except as provided in the Usage Rules, you may not distribute or make the Licensed Application available over a network where it could be used by multiple devices at the same time. You may not transfer, redistribute or sublicense the Licensed Application and, if you sell your Apple Device to a third party, you must remove the Licensed Application from the Apple Device before doing so.

b. Consent to Use of Data

You agree that Licensor may collect and use technical data and related information—including but not limited to technical information about your device, system and application software, and peripherals—that is gathered periodically to facilitate the provision of software updates, product support, and other services to you (if any) related to the Licensed Application. Licensor may use this information, as long as it is in a form that does not personally identify you, to improve its products or to provide services or technologies to you.

c. Termination

This Standard EULA is effective until terminated by you or Licensor. Your rights under this Standard EULA will terminate automatically if you fail to comply with any of its terms.

d. External Services

The Licensed Application may enable access to Licensor's and/or third-party services and websites (collectively and individually, "External Services"). You agree to use the External Services at your sole risk. Licensor is not responsible for examining or evaluating the content or accuracy of any third-party External Services, and shall not be liable for any such third-party External Services. Data displayed by any Licensed Application or External Service, including but not limited to financial, medical and location information, is for general informational purposes only and is not guaranteed by Licensor or its agents. You will not use the External Services in any manner that is inconsistent with the terms of this Standard EULA or that infringes the intellectual property rights of Licensor or any third party. You agree not to use the External Services to harass, abuse, stalk, threaten or defame any person or entity, and that Licensor is not responsible for any such use. External Services may not be available in all languages or in your Home Country, and may not be appropriate or available for use in any particular location. To the extent you choose to use such External Services, you are solely responsible for compliance with any applicable laws. Licensor reserves the right to change, suspend, remove, disable or impose access restrictions or limits on any External Services at any time without notice or liability to you.

SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY FOR PERSONAL INJURY, OR OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU.

In no event shall Licensor's total liability to you for all damages (other than as may be required by applicable law in cases involving personal injury) exceed the amount of fifty dollars (USD 50.00). The foregoing limitations will apply even if the above stated remedy fails of its essential purpose.

1. Description of Service

LINEORA is a mobile application that converts photos into line drawings using AI image generation. Features include:

2. Eligibility

You must be at least 16 years old to use the App.

By installing or using the App, you represent and warrant that you are at least 16 years of age (or the higher minimum age required in your country to consent to data processing) and that you have the legal capacity to enter into these Terms. If you allow a minor to use the App on your device, you are responsible for that use and represent that you are the minor's parent or legal guardian.

3. No Account Required

The App does not require you to create an account or sign in. On first launch our API mints a pseudonymous account for your device — a random UUID and a paired bearer token — which the App stores in the operating system's secure storage. Every request after that authenticates with the bearer token, and the server resolves your account from the token; we never ask for your name, email address, or any other personal identifier unless you volunteer one (for example, when contacting support). The free-render allotment is tracked locally on your device; the server enforces only your purchased credit balance. To move your account to a different device, mint a recovery code in Settings.

4. Privacy and Data Protection

4.1 Privacy Policy

Your use of the App is also governed by our Privacy Policy, which describes how we handle the limited personal data we process. By using the App, you consent to the practices described there.

4.2 AI Rendering and Photo Upload

Image conversion happens on a server. When you tap a style, your photo is uploaded over a TLS-encrypted connection to ZEITARC's cloud library, hosted in Hetzner Object Storage in the European Union. Our render service forwards a copy to third-party AI image-generation providers to produce the requested style, and the returned drawing is also stored in your cloud library so it appears in your gallery across devices and can be compared with the original photo within the App. We do not use your photos or generated drawings to train any model, and we contract only with providers whose API terms commit to the same. You may delete any sketch (and its stored original, when no other sketches reference it) from the in-app gallery at any time.

4.3 Analytics and Crash Reporting

We use anonymous product analytics (PostHog) and crash reporting (Sentry) to understand how features are used and to investigate defects. Neither receives photo content. See the Privacy Policy for details.

5. Your Content

5.1 Ownership

You retain all ownership rights you have in the photos you supply to the App and in the drawings the App produces from them ("Your Content"). We claim no ownership over Your Content.

5.2 Limited License to Us

You grant us a limited, non-exclusive, royalty-free license to host, transmit, process, and serve Your Content for the purposes of rendering the styles you request, storing the resulting drawing and the source photo in your cloud library so it appears in your gallery across devices, and re-fetching the source photo for the in-app compare-with-original view. This license is co-extensive with the lifetime of the stored copy and terminates as soon as you delete the corresponding sketch from the in-app gallery (or we delete it as part of an account-level erasure request). We do not sell, license, use for advertising, or train any model on Your Content.

5.3 Content Responsibility

You are solely responsible for Your Content. You represent and warrant that you have all rights and permissions necessary to use Your Content with the App, and that Your Content does not violate any law or any third-party right.

5.4 Content Guidelines

You agree not to use the App to:

5.5 AI-Generated Output

The App produces images using a third-party AI image-generation model accessed through ZEITARC's render proxy. Output is generated automatically based on the photo you provide; it may contain artifacts, may not be visually accurate, may interpret subjects differently across requests, and is provided "as-is". You are solely responsible for evaluating output before sharing or relying on it.

6. In-App Purchases

6.1 Free Allotment and Paid Items

The App provides a small lifetime allotment of free drawings (currently two per device) without purchase. Beyond the free allotment, the App offers credit packs, processed by the App Store on iOS or the Google Play Store on Android:

Rewarded drawings and exports. When your balance is empty, the App may offer one drawing credit, sharing or printing of one ad-funded drawing, or one PDF build in exchange for completing a rewarded advertisement (Section 2.6 of the Privacy Policy). Offers are optional, depend on advertisement availability and daily limits, and may be disabled. A drawing credit is granted only after Google's signed completion notice reaches our servers; verification delays may cause a reward to appear later. Ad-funded drawings may use the Standard quality render path and their exports may include a Lineora watermark or frame, as shown in the App before the action. Purchased credits provide the paid render and export path while your balance is positive. Rewarded credits have no cash value, and the abuse rules in Section 6.7 apply. iOS advertisements are non-personalised and do not require ATT permission.

6.2 No Auto-Renewing Subscriptions

The App does NOT offer auto-renewing subscriptions. You will not be charged on a recurring basis.

The price displayed at the time of purchase is the price you pay; the App Store or Google Play Store (whichever processed the purchase) handles taxes and any currency conversion.

6.3 Billing

Payment is charged to your App Store or Google Play Store account at the time of purchase, depending on the store you bought from. All billing is handled by that store; we do not see your payment method, billing address, or full account identifiers.

6.4 Refunds

Refunds are administered by Apple (for App Store purchases) under its published policies, or by Google (for Google Play Store purchases) under its published policies. We do not directly issue refunds for in-app purchases — please contact the store you purchased from.

6.5 Restoring Purchases

Credit packs are consumable and are tied to the account on the device that purchased them. To move your credit balance to another device, mint a recovery code in Settings on your existing device, then redeem it in Settings on the new device — the recovery code transfers the whole account, including remaining credits and gallery contents.

6.6 Right of Withdrawal (EU Consumers)

If you are a consumer in the European Union, you have the right to withdraw from a digital-content purchase within 14 days of the transaction without giving any reason, in accordance with the EU Consumer Rights Directive (2011/83/EU).

However, by initiating an in-app purchase you expressly request immediate performance and acknowledge that you lose the right of withdrawal once the digital content has been fully provided. All withdrawal and refund requests are processed through the App Store or Google Play Store (whichever processed the purchase), which handles all billing on our behalf.

6.7 Free Allotment Abuse

The number, refresh schedule, and rules for the free allotment may change over time. Bundling, abusing, or attempting to circumvent the allotment (for example by manipulating device time, repeatedly reinstalling, or using automation) is grounds for revocation of the allotment without refund.

7. Intellectual Property

The App, including its design, features, and code (excluding Your Content), is owned by ZEITARC and protected by copyright, trademark, and other intellectual-property laws. You may not copy, modify, distribute, or create derivative works from the App without our written permission, except to the extent applicable law expressly permits and prohibits this restriction.

"ZEITARC" and "LINEORA", together with associated logos, are trademarks of ZEITARC. All other trademarks, service marks, and logos used in the App are the property of their respective owners.

8. Acceptable Use

You agree not to:

9. Third-Party Services

The App integrates with third-party services including the App Store and Google Play Store (purchase processing), RevenueCat (purchase validation), PostHog (anonymous analytics), Sentry (crash reporting), third-party AI image-generation providers (called by ZEITARC's render service), Hetzner Online GmbH (object storage in the European Union for your uploaded photos and generated drawings), Google LLC's Firebase Cloud Messaging (push notifications when a render finishes), Google LLC's AdMob and User Messaging Platform (rewarded advertisements and regional consent on Android and iOS, described in Section 2.6 of the Privacy Policy), and, in the Android App only, Meta Platforms Ireland Limited (attribution and measurement for our Facebook and Instagram advertising, described in Section 2.5 of the Privacy Policy). Your use of these services is subject to their respective terms and licenses. We are not responsible for the practices of independent third parties.

10. Service Availability

We strive to keep the App available and functional but do not guarantee uninterrupted access. The App may be temporarily unavailable due to maintenance, store outages, updates, or circumstances beyond our control. We may also modify, suspend, or discontinue the App or any feature at any time, with reasonable notice where practicable.

11. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the App will be uninterrupted or error-free, that defects will be corrected, or that the App will produce any specific result. While we take reasonable care in developing the App and in safeguarding the cloud-stored library that backs your gallery, you are responsible for maintaining your own copies of any sketches or originals you wish to retain independently — we do not guarantee perpetual availability of the cloud library, and stored content can become unavailable if you delete a sketch, request account deletion, or the App or the underlying service is discontinued.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, ZEITARC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR LOSS OF GOODWILL, ARISING FROM YOUR USE OF THE APP.

Our total aggregate liability for any claims arising from these Terms or your use of the App shall not exceed the greater of (a) the amount you paid us in the twelve (12) months preceding the claim, or (b) fifty euros (EUR 50).

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by applicable law.

13. Indemnification

You agree to indemnify and hold harmless ZEITARC, its officers, directors, employees, and agents from and against any claims, damages, losses, costs, or expenses (including reasonable legal fees) arising from your use of the App, Your Content, or your violation of these Terms or any law or third-party right.

14. Dispute Resolution

14.1 Informal Resolution

Before filing any formal proceedings, you agree to first contact us at legal.line@zeitarc.com to attempt to resolve any dispute informally. We will make good-faith efforts to resolve disputes within 30 days of receiving your notice.

14.2 Governing Law

These Terms are governed by, and construed in accordance with, the laws of the Islamic Republic of Pakistan, without regard to its conflict-of-laws rules. Where you are a consumer within the European Union, you also enjoy the protection of the mandatory provisions of the consumer-protection laws of your country of residence.

14.3 Jurisdiction

Any disputes that cannot be resolved informally shall be submitted to the courts of competent jurisdiction in Islamabad, Pakistan. If you are a consumer in the EU, you may also bring proceedings in the courts of your country of residence. Nothing in this section restricts any non-waivable right you may have under the consumer-protection law of your jurisdiction.

14.4 EU Online Dispute Resolution

The European Commission provides an online dispute-resolution platform at https://ec.europa.eu/consumers/odr. We are not currently obliged to participate in dispute-resolution proceedings before a consumer arbitration board, but we will always endeavour to resolve disputes directly with you.

15. Changes to Terms

We may modify these Terms at any time. We will notify you of material changes by updating the "Last updated" date at the top of this document and surfacing the change inside the App before it takes effect.

If you do not agree with the updated Terms, you should stop using the App and uninstall it. Continued use of the App after the effective date constitutes acceptance of the updated Terms.

16. Termination

You may stop using the App at any time by uninstalling it. We may suspend or terminate your access to the App, or to any in-app feature, if (i) you breach these Terms, (ii) we are required to do so by law, by Apple, or by Google, or (iii) the App is discontinued. Sections 5, 7, 8, 11–13, and 14.2–14.3 survive termination.

17. General Provisions

17.1 Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect, and the invalid provision shall be enforced to the maximum extent permitted by law.

17.2 Entire Agreement

These Terms, together with our Privacy Policy and the applicable App Store or Google Play Store terms (whichever you installed from), constitute the entire agreement between you and ZEITARC regarding the App, superseding any prior agreements or communications on the same subject matter.

17.3 Assignment

We may assign our rights and obligations under these Terms to another entity in connection with a merger, acquisition, or sale of substantially all of our assets relating to the App, provided that the assignee agrees to be bound by these Terms. You may not assign your rights or obligations without our prior written consent; any attempted assignment in violation of this section is void.

17.4 Force Majeure

We shall not be liable for any failure or delay in performance due to causes beyond our reasonable control, including but not limited to natural disasters, war, terrorism, pandemics, government actions, power failures, internet or platform disruptions, or acts of third parties.

17.5 No Waiver

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision. Any waiver must be in writing and signed by us.

17.6 Notices

We may send you notices by surfacing them inside the App or by posting on our website at zeitarc.com. You may send notices to us at legal.line@zeitarc.com.

17.7 Apple as Third-Party Beneficiary

If you installed LINEORA from the App Store, you and ZEITARC acknowledge that Apple Inc. and its subsidiaries are third-party beneficiaries of these Terms, and that, upon your acceptance of these Terms, Apple shall have the right (and shall be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.

17.8 Google as Third-Party Beneficiary

If you installed LINEORA from the Google Play Store, you and ZEITARC acknowledge that Google LLC and its subsidiaries are third-party beneficiaries of these Terms, and that, upon your acceptance of these Terms, Google shall have the right (and shall be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.
