Terms of Use & End User License Agreement
1. Agreement
These Terms of Use and End User License Agreement (the “Agreement”) are between you and jumpEFB (“jumpEFB,” “we,” “us”) and govern your use of the jumpEFB application and related services (the “App”). By downloading, installing, or using the App, you agree to this Agreement. If you do not agree, do not use the App.
2. License
We grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own use, subject to this Agreement and the usage rules of the app store from which you obtained the App. You may not copy, modify, distribute, sell, sublicense, reverse engineer, or create derivative works of the App except where such restriction is prohibited by law.
3. Aviation safety disclaimer
The App is a situational-awareness and planning aid. It is advisory only and is not certified for, and must not be relied upon as, a primary means of navigation, terrain avoidance, traffic avoidance, weather avoidance, weight-and-balance compliance, or any other flight-critical function.
You acknowledge and agree that:
- As pilot in command, you are solely responsible for the safe operation of your aircraft, for compliance with all applicable regulations and operating limitations, and for every operational decision — including the decision to release jumpers.
- Information presented by the App (including spot solutions, jump-run guidance, green-light indications, weight-and-balance calculations, glide projections, weather, and winds aloft) may be inaccurate, incomplete, outdated, or unavailable, and depends on inputs — GPS signal, forecast data, and data you enter — that are outside our control.
- The App is not a substitute for the aircraft flight manual or pilot's operating handbook, official weather briefings, official aeronautical publications, or your own judgment and training.
- You will independently verify any information from the App before acting on it.
4. Assumption of risk
Aviation and skydiving operations are inherently dangerous and can result in serious injury or death. To the maximum extent permitted by law, you knowingly and voluntarily assume all risks arising from or related to your use of the App in connection with such activities.
5. Your data and account
Some features may require an account or connectivity to third-party services (for example, dropzone connectivity via jumpDZM on Pro plans). You are responsible for the accuracy of data you enter, including aircraft profiles and weight-and-balance inputs, and for maintaining the confidentiality of your account credentials. Our collection and use of personal information is described in the Privacy Policy.
6. Subscriptions and purchases
Paid features, if any, are billed through the app store from which you obtained the App, and are subject to that store's payment, renewal, cancellation, and refund terms. Prices and features may change; changes will not apply retroactively to periods already paid.
7. No warranty
THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AVAILABILITY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT DATA PRESENTED WILL BE ACCURATE OR CURRENT.
8. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, JUMPEFB AND ITS OFFICERS, EMPLOYEES, CONTRACTORS, AND SUPPLIERS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF LIFE, PERSONAL INJURY, PROPERTY DAMAGE, LOST PROFITS, OR LOST DATA, ARISING FROM OR RELATED TO YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE APP SHALL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID US FOR THE APP IN THE TWELVE MONTHS PRECEDING THE CLAIM OR FIFTY U.S. DOLLARS (US$50). SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.
9. Indemnification
You agree to indemnify and hold harmless jumpEFB from claims, damages, and expenses (including reasonable attorneys' fees) arising from your use of the App, your violation of this Agreement, or your violation of any law or regulation, including aviation regulations.
10. Third-party services and data
The App may display data from third-party sources (including weather and winds-aloft providers and mapping data). We are not responsible for the accuracy or availability of third-party data or services.
11. App store terms
If you obtained the App from the Apple App Store: this Agreement is between you and jumpEFB only, not Apple; Apple has no obligation to furnish maintenance or support; in the event of a failure of the App to conform to an applicable warranty, you may notify Apple and Apple will refund the purchase price (if any), and Apple has no other warranty obligation; Apple is not responsible for addressing any claims relating to the App, including product-liability, regulatory, and consumer-protection claims; and Apple and its subsidiaries are third-party beneficiaries of this Agreement with the right to enforce it against you. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. government restricted-party list. Equivalent provisions apply for Google Play where required by its terms.
12. Termination
We may suspend or terminate your license if you breach this Agreement. You may terminate at any time by deleting the App. Sections 3, 4, 7, 8, 9, and 13 survive termination.
13. Governing law
This Agreement is governed by the laws of the state in which jumpEFB is organized, without regard to conflict-of-laws principles, and any dispute shall be brought in the state or federal courts located there.
14. Changes
We may update this Agreement from time to time. Material changes will be posted at this page with a new effective date; continued use of the App after changes take effect constitutes acceptance.
