App Terms of Use

Effective date: August 21, 2026

These Terms of Use ("Terms") are a legal agreement between you and AIorNot, Inc. ("AI or Not," "we," "us") covering your use of the AI or Not mobile application for iOS, including the on-device AI detection model embedded in it (together, the "App"). By downloading, installing, or using the App you agree to these Terms. If you do not agree, do not use the App.

These Terms are between you and AI or Not only, not with Apple Inc. ("Apple"). Apple is not responsible for the App or its content. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

1. The App and the Model

The App analyzes text you provide and estimates the likelihood that it was generated by artificial intelligence. The analysis runs entirely on your device using a machine-learning model embedded in the App (the "Model"). The Model, including its architecture, weights, parameters, tokenizer, calibration data, and any updates to them, is part of the App and is protected by copyright, trade secret, and other intellectual property laws.

2. License, Not Sale

We grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App, including the Model, on Apple-branded devices that you own or control, as permitted by the App Store Terms of Service (including its Usage Rules, which allow Family Sharing where enabled). The App and the Model are licensed to you, not sold. We and our licensors retain all right, title, and interest in and to the App and the Model, including all copies of the Model stored on your device. "Owning" or "unlocking" the detector in our marketing refers to this lifetime license and the fact that the Model runs privately on your device; it does not transfer ownership of the Model's intellectual property.

3. Pro Purchase ("Lifetime" Unlock)

The App offers a one-time in-app purchase ("Pro") that removes usage limits and enables fully offline operation. "Lifetime" means the life of the App: for as long as we offer the App, your Pro unlock remains active on the same Apple Account at no additional charge, and includes any updates to the App and Model that we make generally available to Pro users. It does not obligate us to offer the App, or any particular feature or level of accuracy, indefinitely (see Section 8).

Payment is processed by Apple through your Apple Account; it is a non-consumable purchase, not a subscription, and no recurring-billing or auto-renewal terms apply. We never receive your payment card details. Refunds are handled by Apple under the App Store terms; we cannot issue App Store refunds directly. You can restore your purchase on a new device with the same Apple Account using "Restore Purchases." Prices may change for future purchasers without affecting an existing unlock.

4. Model Protections — Prohibited Uses of the Model

Because the Model is distributed to your device, these restrictions are a condition of your license. Except to the extent a restriction is prohibited by applicable law, you agree that you will not, and will not permit or help anyone else to:

• Extract or copy the Model. Access, copy, dump, extract, export, or distribute the Model or any portion of it (including weights, checkpoints, compiled artifacts, parameters, architecture, tokenizer files, or calibration data) outside the App, whether from the App bundle, an App Store package, device storage, memory, backups, or otherwise.
• Break or bypass protections. Decrypt, decode, or circumvent, or attempt to circumvent, any encryption (including Core ML model encryption), obfuscation, licensing check, App Store DRM, or other technical protection measure applied to the App or the Model. You acknowledge these are "technological measures" under 17 U.S.C. § 1201 (DMCA) and similar laws, and that circumvention is independently actionable.
• Reverse engineer. Decompile, disassemble, reverse engineer, or otherwise attempt to derive the source code, architecture, weights, training data, or underlying ideas of the App or the Model, except to the limited extent applicable law expressly permits despite this restriction.
• Distill or train on the Model. Use the Model, its outputs, scores, highlights, or intermediate values to train, fine-tune, calibrate, distill, benchmark for development purposes, or otherwise improve any machine-learning model, detection system, or dataset, or to build any product or service that competes with the App or with AI or Not's services.
• Wrap or resell the Model. Host, serve, deploy, or expose the App or the Model, directly or indirectly, as an API, web service, bot, plug-in, or other interface usable by third parties; use the App to provide detection results to third parties as a service (whether or not for payment); publish, distribute, open-source, sell, rent, lease, or otherwise make the Model available to any third party; or operate the App on a service-bureau, timesharing, or outsourced basis.
• Automate or bulk-query. Use scripts, automation, accessibility hooks, or other means to submit queries at scale, harvest outputs, or systematically map the Model's behavior, including for the purpose of constructing training data or evading detection.
• Circumvent limits. Circumvent, or attempt to circumvent, free-tier limits, usage metering, or purchase entitlement checks.
• Remove notices, watermarks, or provenance markers. The Model may contain digital watermarks, fingerprints, or provenance markers. You agree not to remove, alter, or obscure them (or any proprietary notices), you consent to our use of such markers to identify unauthorized copies, and you will not represent the Model or its outputs as your own or another party's technology.
• Transfer outside Usage Rules. Sell, rent, lease, lend, sublicense, or transfer the App or the Model except as expressly allowed by the App Store Usage Rules.

Attempting any of the above automatically terminates your license under Section 9 and may result in civil and criminal liability. You acknowledge that extraction, distillation, or disclosure of the Model would cause us irreparable harm for which money damages are inadequate, and that we are entitled to seek injunctive relief in any court of competent jurisdiction notwithstanding Section 13.

5. Your Content and Results

Text you submit for analysis is processed on your device and is not transmitted to us. You are responsible for the text you analyze and must have the right to use it. Your check history is stored locally on your device and can be deleted by you at any time.

Results are probabilistic estimates, not facts. The App reports a statistical likelihood, not a determination, that text was AI-generated. False positives and false negatives occur. Results are provided for informational purposes only and are not a certification of authorship. You agree not to rely on the App's output as the sole basis for any decision that has legal, academic, employment, financial, or similarly significant effects on any person, and you are solely responsible for how you use and communicate results. Any accuracy figures we publish reflect performance on our evaluation sets and do not guarantee accuracy on your text.

6. Acceptable Use

You may use the App only for lawful purposes, for personal or internal business use, in compliance with these Terms and applicable law (including export and privacy laws). You may not use the App to harass, defame, or harm others, including by publishing accusations about a person based on the App's output without appropriate diligence.

7. Intellectual Property; Feedback

All content in the App (software, Model, text, graphics, logos, and trademarks including "AI or Not") belongs to us or our licensors. If you send us feedback or suggestions, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them without restriction or compensation.

8. Updates, Changes, and Availability

We may update the App and the Model (including to improve accuracy, add or remove features, replace or re-encrypt the Model, or maintain compatibility with iOS) and may require you to install updates to continue using the App. Updates are provided "AS IS" under Section 10. We may modify or discontinue the App. If we permanently discontinue the App while you hold a Pro unlock, the then-current version on your device will continue to function to the extent iOS permits, but we are not obligated to provide further updates, support, or compatibility. Apple has no obligation to furnish maintenance or support for the App; to the extent any is required by law, that obligation is ours alone.

9. Termination

These Terms remain in effect until terminated. Your rights terminate automatically, without notice, if you breach these Terms — including any Model Protection in Section 4 — and no refund will be due for a termination caused by your breach. Upon termination you must stop using the App and delete all copies. Sections 4, 5, 7, and 9 through 16 survive termination.

10. Warranty Disclaimer

THE APP, THE MODEL, AND ALL RESULTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OR ERROR-FREE OPERATION. In the event of any failure of the App to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you; to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App. Some jurisdictions limit warranty disclaimers, so parts of this section may not apply to you.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, AI OR NOT WILL NOT BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS, LOST DATA, REPUTATIONAL HARM, OR DAMAGES ARISING FROM DECISIONS MADE IN RELIANCE ON THE APP'S RESULTS). OUR AGGREGATE LIABILITY UNDER THESE TERMS WILL NOT EXCEED THE GREATER OF (A) US $100 OR (B) THE AMOUNTS YOU PAID US FOR THE APP IN THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

12. Indemnification

You will indemnify and hold harmless AI or Not and its officers, directors, employees, agents, licensors, and affiliates from claims, damages, losses, and expenses (including reasonable attorneys' fees) arising from (a) your use or misuse of the App or its results, (b) your violation of these Terms, including Section 4, or (c) your violation of any law or the rights of any third party.

13. Dispute Resolution; Arbitration; Class Waiver

Except as provided below, any dispute between you and AI or Not will be resolved by binding, individual arbitration in Alameda County, California, in English, before one arbitrator under the JAMS Streamlined Arbitration Rules, and YOU AND AI OR NOT EACH WAIVE THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. The parties will first attempt in good faith to resolve any dispute informally by contacting support@aiornot.com. For claims under $5,000, we will pay the arbitration fees. Either party may (i) bring qualifying claims in small-claims court in Alameda County or in your county of residence, and (ii) seek injunctive or other equitable relief in court for actual or threatened infringement or misappropriation of intellectual property — including any breach of Section 4 (Model Protections). You may opt out of this arbitration agreement by emailing support@aiornot.com within 30 days of first accepting these Terms with your name, contact information, and a clear statement that you opt out. If the class-action waiver is found unenforceable, this arbitration section is void. Disputes not subject to arbitration will be brought exclusively in the state or federal courts located in Alameda County, California.

14. Governing Law

These Terms are governed by the Federal Arbitration Act, applicable federal law, and the laws of the State of California, without regard to conflict of laws rules.

15. Legal Compliance; Apple Provisions

You represent that (a) you are not located in a country subject to a U.S. Government embargo or designated a "terrorist supporting" country, and (b) you are not on any U.S. Government list of prohibited or restricted parties. You must comply with applicable third-party terms (for example, your wireless carrier's terms) when using the App. We, not Apple, are responsible for the App, for maintenance and support, for addressing any claims by you or a third party relating to the App (including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and consumer protection or similar claims), and for the investigation, defense, settlement, and discharge of any claim that the App infringes a third party's intellectual property rights. Where these Terms are silent, Apple's standard Licensed Application End User License Agreement applies.

16. Miscellaneous

We may modify these Terms; if we make material changes we will give notice in the App or by other reasonable means, and continued use after the effective date constitutes acceptance. You may not assign these Terms; we may assign them without restriction. If a provision is found unenforceable it will be limited to the minimum extent necessary and the rest will remain in effect. These Terms, together with the AI or Not Privacy Policy for the App, are the entire agreement between you and us about the App. Our failure to enforce a provision is not a waiver.
