Terms of Service

1. Who these terms are between

These terms govern your use of the Airtenance application ("Airtenance", "the service") — the app for iOS, Android and the browser as well as the website — operated by StagWorks, Maximilian Rosnauer und Benjamin Seeger GbR ("we", "us"). Our contact and postal details are in the legal notice. By creating an account you agree to these terms and to the Privacy Policy.

2. What Airtenance does

Airtenance is a record-keeping and analysis tool for a flying club's fuel and oil consumption and maintenance due-dates. It stores the events, flight-log imports and logbook photographs a club enters, and computes figures from them.

3. Accounts

You need an account to use Airtenance. You must give a valid email address and keep your credentials confidential. You are responsible for activity under your account. Tell us promptly if you believe it has been compromised. Accounts are for named individuals; do not share one.

4. Clubs and shared data

Within a club, every member can read and write all of that club's data. When you enter, import, photograph or upload data into a club, you make it available to the club's other members, and you confirm you are entitled to share it — including any flight-log export and any logbook photographs, and any personal data of other pilots contained in them. Role labels within a club are descriptive and do not restrict access.

You are responsible for the accuracy of what you enter. Invite codes are a capability: whoever holds a club's code can join that club, so treat it like a password and rotate it when needed.

5. Not an authoritative flight or maintenance record

Airtenance is a support tool. Its figures are derived from the data entered and are only as good as that data. Logbook entries are hand-written and are read off by people and by machines — any figure shown in Airtenance may be incomplete or wrong.

The physical aircraft logbook remains the legal record. Airtenance does not replace it. Consumption rates, remaining quantities, trends and due-dates shown in Airtenance are advisory and serve trend analysis. The pilot in command remains responsible for verifying actual fuel and oil quantities on the aircraft before every flight, and the club remains responsible for its airworthiness and maintenance obligations. Do not rely on Airtenance as the sole basis for an airworthiness, flight-planning or dispatch decision.

6. Acceptable use

Do not use Airtenance to store data you are not entitled to hold or share, do not attempt to access another club's data, do not probe, disrupt or overload the service, do not circumvent the app's device attestation, and do not upload malicious content. We may suspend access that threatens the service or other users.

7. Availability and changes

Airtenance is provided on an "as available" basis. We may change, suspend or discontinue features, and perform maintenance that causes downtime. We aim to give notice of significant changes where practical. Older versions of the app may stop working after a change to the service until they are updated.

8. Your content

You and your club keep all rights in the data you enter. You grant us the limited right to store, process, transmit and display it as needed to run the service and provide it to your club. We do not use your content for any other purpose. You can download your data and delete your account from the profile screen; see the Privacy Policy for what deletion does.

9. Fees

Any fees, and the terms for paid use, are set out separately in the offer or agreement applicable to your club. Where no such agreement exists, the service is provided without charge and without any commitment to continue it. The app contains no in-app purchases.

10. Warranty and liability

The service is provided without warranty of any kind, including as to accuracy, availability or fitness for a particular purpose, to the extent permitted by law.

We are liable without limit for damage caused intentionally or by gross negligence, and for injury to life, body or health. For slight negligence we are liable only where a material contractual obligation is breached, and then only for the foreseeable, contract-typical damage. All other liability is excluded. Nothing in these terms limits liability that cannot be limited by law.

11. Term and termination

You may stop using Airtenance and delete your account at any time. We may terminate or suspend your access for a material breach of these terms, or on reasonable notice if we discontinue the service.

12. App stores

If you obtain the app through the Apple App Store or Google Play, the terms of that store apply in addition. Apple and Google are not parties to these terms and have no maintenance or support obligations for Airtenance; claims under these terms are directed at us alone.

13. Governing law

German law applies, to the extent not overridden by mandatory consumer protection law of your country of residence. If any provision is or becomes invalid, the remaining provisions stay in force.

14. Changes to these terms

We may update these terms as the service changes. Material changes raise the terms version; when that happens you may be asked to accept the new version before continuing to use the service. The date above reflects the current version.
