Terms & Conditions

1. Acceptance and Eligibility

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

If you are under 18, a parent or legal guardian must read and accept these Terms on your behalf before you use the App. That parent or guardian is the contracting party under these Terms, is responsible for your use of the App, and agrees to be bound by these Terms. All purchases must be made by an adult.

By using the App you represent that you meet these requirements and that you are not barred from using the App under the laws of the United States or your state of residence.

2. License Grant

AIVIATION LLC grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the App for your own personal, non-commercial reference purposes on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.

We may modify, suspend, or discontinue the App or any part of it at any time. We have no obligation to provide support or maintenance beyond what we choose to offer.

3. AI Features Disclaimer

Plus and Pro subscribers may access AI-powered features (summaries, explanations) using on-device Apple Foundation Models. Pro subscribers may additionally use cloud-based AI Q&A, which transmits question text to AIVIATION servers. AI-generated content from either source may contain errors or misinterpretations of regulations. This content is for study purposes only and does not constitute official FAA interpretation. Always verify with official FAA sources before making any operational decisions.

4. Subscription Terms

5. Intellectual Property

Federal regulations (14 CFR, 49 CFR) and the Aeronautical Information Manual are U.S. government publications in the public domain. AIVIATION LLC claims no copyright in the underlying regulatory text. The app's UI, search functionality, data compilation, AI features, and branding are © 2026 AIVIATION LLC. "RegBrief" and "AIVIATION" are trademarks of AIVIATION LLC. All rights not expressly granted in Section 2 are reserved.

6. Prohibited Uses

• Reverse engineering, decompiling, or disassembling the app, except to the extent that restriction is prohibited by applicable law
• Citing app content as official FAA guidance in enforcement proceedings
• Distributing, reselling, renting, leasing, or sublicensing access
• Scraping, bulk-downloading, or systematically extracting the app's content or the responses of its AI features, including to build a competing product or to train a machine-learning model
• Interfering with, overloading, or attempting to gain unauthorized access to the app or our servers
• Using the app for any unlawful purpose

7. Feedback

If you send us feedback, suggestions, bug reports, or ideas about the App, you grant AIVIATION a perpetual, irrevocable, worldwide, non-exclusive, fully paid, royalty-free license to use them for any purpose, without attribution or compensation. Please do not send us anything you consider confidential or proprietary.

8. Privacy

Our Privacy Policy describes what information the App collects, how we use it, how long we keep it, who receives it, and the choices and rights you have. It is incorporated into these Terms by reference. By using the App you acknowledge that you have read it. If these Terms and the Privacy Policy conflict on any question about the collection, use, retention, or disclosure of your information, the Privacy Policy controls.

9. Third-Party Services, Other Users, and Release

Third-party services. The App links to and relies on services operated by others, including Apple, Amazon Web Services, the FAA, and the Government Publishing Office's eCFR. We do not control them, do not endorse them, and are not responsible for them. Your use of a third-party service is at your own risk and is governed by that party's own terms and privacy practices. You agree to comply with any applicable third-party terms when using the App.

Other users. Your interactions with any other user of the App are solely between you and that person. We are not responsible for any loss or harm arising from those interactions.

Release. To the fullest extent permitted by law, you release AIVIATION LLC and its members, officers, employees, and agents from all claims, demands, and damages arising out of or related to third-party services and to your interactions with other users. If you are a California resident, you waive California Civil Code Section 1542, which provides: "A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party." This release does not extend to claims arising out of AIVIATION's own conduct, and nothing in it waives any right you have that cannot be waived under applicable law.

10. Indemnification

You agree to defend, indemnify, and hold harmless AIVIATION LLC and its members, officers, employees, and agents from and against any third-party claim, and any resulting damages, losses, and reasonable costs and attorneys' fees, arising out of (i) your use of the App, (ii) your breach of these Terms, or (iii) your violation of any law or of the rights of a third party. We will notify you promptly of any claim we become aware of, and we may assume sole control of the defense and settlement of the claim at your expense, in which case you agree to cooperate. You may not settle any claim in a way that imposes an obligation on AIVIATION without our prior written consent. This Section does not apply to a claim caused by AIVIATION's own conduct, and it does not require you to indemnify us for our own negligence or willful misconduct.

11. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AIVIATION LLC AND ITS SUPPLIERS DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, AND STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES OF ACCURACY, COMPLETENESS, OR QUIET ENJOYMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, TIMELY, SECURE, ERROR-FREE, OR FREE OF HARMFUL CODE.

REGULATORY CONTENT MAY BE OUTDATED OR CONTAIN ERRORS. WE DO NOT WARRANT THAT THE APP REFLECTS CURRENT FAA REGULATIONS. AI-GENERATED CONTENT MAY BE INCORRECT.

Some states do not allow the exclusion of certain implied warranties, so some of the above may not apply to you. In that case, any implied warranty that cannot be disclaimed is limited in duration to the shortest period permitted by that state's law.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW: (A) AIVIATION LLC AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY LOST PROFITS, LOST DATA, COST OF SUBSTITUTE PRODUCTS, OR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THESE TERMS OR YOUR USE OF, OR INABILITY TO USE, THE APP; AND (B) OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE APP IS LIMITED TO THE GREATER OF (i) $50 USD AND (ii) THE AMOUNT YOU PAID AIVIATION FOR THE APP IN THE SIX MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. THE EXISTENCE OF MORE THAN ONE CLAIM DOES NOT INCREASE THIS LIMIT.

These limits apply regardless of the theory of liability and even if a remedy fails of its essential purpose. Some states do not allow the exclusion or limitation of incidental or consequential damages, so some of the above may not apply to you. Nothing in these Terms limits liability for fraud, fraudulent misrepresentation, gross negligence, or willful misconduct, or any other liability that cannot be limited under applicable law.

13. Term, Termination, and Survival

These Terms apply from the first time you use the App and remain in effect until terminated. You may terminate at any time by deleting the App; deleting the App does not by itself cancel a subscription, which you cancel through Apple as described in Section 4.

We may suspend or terminate your access to the App, or to a feature of it, if you materially breach these Terms, if we reasonably believe your use creates a legal or security risk, or if we discontinue the App. Where practical and lawful, we will give you notice first. If we terminate your access without cause while you hold a paid subscription, you may request a refund of the unused portion through Apple.

Sections 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17 survive termination.

14. Apple-Specific Terms

This Section applies to your use of the App obtained through Apple's App Store. If it conflicts with another provision of these Terms, this Section controls as to the subject matter of the conflict.

• Acknowledgement. These Terms are between you and AIVIATION LLC only, not with Apple. AIVIATION, not Apple, is solely responsible for the App and its content.
• Scope of license. The license granted in Section 2 is limited to a non-transferable license to use the App on any Apple-branded product that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you through Family Sharing or volume purchasing.
• Maintenance and support. AIVIATION is solely responsible for providing any maintenance and support for the App. Apple has no obligation to furnish any maintenance or support.
• Warranty. AIVIATION is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App.
• Product claims. AIVIATION, not Apple, is responsible for addressing any claim by you or a third party relating to the App or your possession or use of it, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and any claim arising under consumer protection, privacy, or similar legislation.
• Intellectual property rights. If a third party claims that the App or your possession and use of it infringes that party's intellectual property rights, AIVIATION, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of that claim.
• Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Developer name and address. AIVIATION LLC, c/o Northwest Registered Agent, 7901 4th Street North, Suite 300, St. Petersburg, FL 33702. Questions, complaints, and claims about the App may be directed to support@aiviation.dev or to telephone 316-302-5551.
• Third-party terms. You must comply with any applicable third-party terms of agreement when using the App.
• Third-party beneficiary. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

15. State-Specific Notices

This Section applies to you only to the extent you are subject to the law of the state identified. Where a provision in this Section conflicts with another provision of these Terms, this Section controls for users subject to that state's law.

16. General

16.1 Changes to these Terms. We may update these Terms. Updated Terms will be posted here with a new effective date, and material changes will be made prominent in the App or on this site before they take effect. Continued use after the new effective date constitutes acceptance.

16.2 Governing law and venue. These Terms and any dispute arising out of them or the App are governed by the laws of the State of Florida, without regard to conflict-of-law principles. You and AIVIATION consent to the exclusive jurisdiction and venue of the state and federal courts located in Florida. Notwithstanding the foregoing: (a) either party may seek injunctive or other equitable relief to protect its intellectual property in any court of competent jurisdiction; (b) either party may bring an individual claim in small claims court; and (c) nothing in these Terms requires a California resident to resolve a controversy arising in California outside California, or under the law of a state other than California, and nothing in these Terms deprives you of any non-waivable protection of the consumer-protection law of your state of residence.

16.3 Export controls. You agree not to export, re-export, or transfer the App or any technical data obtained from it in violation of U.S. export control laws or other applicable regulations.

16.4 Electronic communications and notices. The App has no accounts and we hold no email address for you, so we cannot email you. You therefore agree that notices we post in the App or on regbrief.app satisfy any legal requirement that a notice be in writing, and that they have the same effect as a notice delivered by mail or email. Check the App and this site for notices. You may give us notice by email to support@aiviation.dev.

16.5 Accessibility. AIVIATION is committed to making the App usable by everyone, including people with disabilities, and we endeavor to conform to the Web Content Accessibility Guidelines (WCAG) 2.1, Level AA. If you have difficulty using any part of the App, or a suggestion for improving it, contact support@aiviation.dev and we will make reasonable efforts to help.

16.6 Entire agreement; severability; no waiver; assignment. These Terms, together with the Privacy Policy, are the entire agreement between you and AIVIATION about the App and supersede any prior agreement on that subject. If a provision is held invalid or unenforceable, it will be modified to the minimum extent necessary to make it enforceable, or, if it cannot be, severed, and the rest remains in effect. Our failure to enforce a provision is not a waiver of it. "Including" means "including without limitation." You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets. These Terms bind permitted assignees.
