1. Agreement to these terms
These Terms of Service (the “Terms”) are a legal agreement between you and GAToday, LLC DBA JKM Aerospace (“JKM Aerospace,” “we,” “us,” or “our”) governing your use of the App Four application for Apple iOS, including all updates, documentation, and related services (the “App”).
By downloading, installing, or using the App, you accept these Terms and our Privacy Policy. If you do not agree, do not use the App and delete it from your devices. You must be at least 13 years old, or the age of digital consent where you live, to use the App.
2. License
We grant you a limited, non-exclusive, non-transferable, revocable license to download and use one copy of the App on Apple-branded devices that you own or control, as permitted by the Apple Media Services Terms and Conditions, including the Licensed Application End User License Agreement. This license is for your personal or internal business use. We reserve all rights not expressly granted.
3. Restrictions
You agree not to:
- copy, modify, translate, or create derivative works of the App;
- reverse engineer, decompile, or disassemble the App, except to the extent that applicable law expressly permits it;
- rent, lease, lend, sell, sublicense, or otherwise distribute the App;
- remove or obscure any proprietary notices;
- use the App in violation of any law or regulation, or in any way that could damage, disable, or impair the App; or
- use the App to build a competing product or service.
4. Pricing and purchases
App Four is currently offered at no charge. We may introduce paid features, one-time purchases, or subscriptions in the future. If we do, pricing and renewal terms will be shown in the App Store before you buy, and any auto-renewing subscription can be managed or cancelled in your Apple Account settings.
All purchases and refunds are handled by Apple under the App Store terms you agreed to with Apple. We cannot issue refunds directly; refund requests should be made to Apple.
5. Safety and operational limits
App Four is a planning and reference aid only. It is not certified avionics, it is not approved for navigation, and it is not a substitute for your aircraft’s approved flight manual, checklists, current charts and aeronautical data, weather briefings, or certified onboard equipment.
You are responsible for independently verifying every result before you rely on it. Data, performance figures, and calculations may contain errors, may be based on assumptions that do not match your aircraft or conditions, and may become outdated. The pilot in command remains solely responsible for the safe and legal conduct of every flight, including compliance with all applicable aviation regulations.
Do not operate the App in a way that distracts from flying the aircraft or that conflicts with sterile cockpit requirements or the rules of your operation.
6. Your content
You retain ownership of any data, profiles, or other content you create or enter in the App (“Your Content”). Your Content is stored on your device and, if you enable it, in your own iCloud account. You are responsible for maintaining your own backups and for the accuracy of the information you enter.
7. Intellectual property
The App, including its software, design, text, graphics, icons, and the JKM Aerospace name and logos, is owned by GAToday, LLC and is protected by copyright, trademark, and other laws. Nothing in these Terms transfers any intellectual property rights to you.
8. Updates and availability
We may release updates, change features, or discontinue the App at any time. Some updates may be required for the App to continue functioning. We do not guarantee that the App will be available without interruption or that it will remain compatible with future versions of iOS or any particular device.
9. Disclaimer of warranties
THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, GAToday, LLC DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY RESULT OR CALCULATION PRODUCED BY THE APP IS ACCURATE OR SUITABLE FOR YOUR PURPOSE. Some jurisdictions do not allow the exclusion of implied warranties, so some of these exclusions may not apply to you.
10. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, GAToday, LLC AND ITS OWNERS, MEMBERS, AND CONTRACTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, PROPERTY, OR PERSONAL INJURY ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE OR (B) TWENTY-FIVE U.S. DOLLARS ($25).
11. Indemnification
You agree to indemnify and hold harmless GAToday, LLC from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys’ fees) arising out of your use of the App, your violation of these Terms, or your violation of any law or the rights of a third party.
12. Apple-specific terms
The following applies because the App is distributed through the Apple App Store:
- These Terms are between you and GAToday, LLC only, not with Apple. Apple is not responsible for the App or its content.
- Apple has no obligation to provide maintenance or support for the App.
- If the App fails to conform to any applicable warranty, you may notify Apple and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
- Apple is not responsible for addressing any claim by you or a third party relating to the App, including product liability claims, claims that the App fails to conform to a legal requirement, and claims under consumer protection or similar legislation.
- Apple is not responsible for investigating, defending, settling, or discharging any third-party claim that the App infringes intellectual property rights.
- You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
- Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce them against you.
13. Term and termination
These Terms remain in effect until terminated. They terminate automatically if you fail to comply with them, and you may terminate them at any time by deleting the App from your devices. Sections that by their nature should survive termination — including disclaimers, limitations of liability, and governing law — will survive.
14. Governing law
These Terms are governed by the laws of the State of [STATE], United States, without regard to its conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. You and GAToday, LLC agree to the exclusive jurisdiction of the state and federal courts located in that jurisdiction, except that either party may seek injunctive relief in any court of competent jurisdiction. If you are a consumer, this does not deprive you of the protection of mandatory consumer law in your country of residence.
15. Changes and contact
We may revise these Terms from time to time. When we do, we will update the “Last updated” date above and, for material changes, provide notice in the App or on our website. Continued use of the App after a change takes effect means you accept the revised Terms. If any provision is found unenforceable, the remaining provisions stay in effect.
