Terms of Service

1. Scope

These terms apply to the use of the hitPR app, operated by Christian Geißler, Frankfurt am Main, Germany. By downloading and using hitPR, you agree to these terms. An account is not required for basic functionality.

Use of the app is permitted from age 16.

2. Use of the app

hitPR is a strength training app available for free. An account is optional and enables cloud backup and cross-device synchronization.

You are granted a non-exclusive, non-transferable, personal right of use. App content (exercise catalog, images, text) is protected by copyright.

You are responsible for the accuracy of your entered data. Reverse engineering, decompilation, or misuse of the app is not permitted, except where mandatorily allowed by law (in particular §§ 69d, 69e of the German Copyright Act for interoperability purposes).

If you use an account, you are responsible for keeping your login credentials (e.g. Google or Apple sign-in) confidential. You are responsible for activity that takes place via your account, unless the unauthorized use is not attributable to you.

In the event of serious or repeated breaches of these terms, in particular misuse, we reserve the right to temporarily or permanently suspend your cloud account and access to paid features. Further statutory claims remain unaffected.

3. Cloud backup

Cloud backup is part of hitPR Pro and is used for data protection. Backups are stored encrypted on EU servers. Body data (weight, measurements) is only included in cloud backup when explicitly enabled in settings. Progress photos are always excluded from cloud backup and exist only locally. We cannot guarantee 100% availability of the cloud service; maintenance windows and temporary outages are possible according to the state of the art. You are responsible for regular local backups (JSON export).

4. Paid features

hitPR offers all training features for free. hitPR Pro extends the analysis period, enables cloud backup and unlocks the Wear OS Watch Companion. Pro is available as a subscription (monthly or yearly) or as a one-time purchase (Lifetime). Payments are handled exclusively through the Apple App Store or Google Play Store. Purchases and refunds are subject to the respective store's cancellation and refund policies.

5. Subscriptions & one-time purchase

hitPR Pro is available as a subscription (monthly or yearly) or as a one-time purchase (Lifetime). Payments are processed through the Apple App Store or Google Play Store. Subscriptions automatically renew for the chosen period unless cancelled at least 24 hours before the end of the current period. Cancellation is done through the account settings of the respective store. Partial billing periods are not refunded. The one-time purchase grants unlimited access without automatic renewal.

6. Account deletion

You can delete your account at any time in settings. All cloud data (profile, backups) and local body data including progress photos will be permanently deleted.

7. Fitness notice

hitPR is not a medical product and does not replace medical advice, diagnosis, or treatment.

Training suggestions, progression recommendations, and calculated values (e.g. Training Max, Estimated 1RM, recommended set ranges per muscle group) are based on the 2025 ACSM Position Stand and general sports science and are estimates — not individual training or health advice.

You are responsible for the execution of exercises, the choice of training weights, and assessing your own physical capacity. Use of the app and implementation of training suggestions is at your own risk.

If you have health conditions or pre-existing medical issues, please consult your doctor before starting a training program.

8. Limitation of liability

The statutory warranty rights for digital products (Sections 327 et seq. of the German Civil Code, BGB) apply to the app. We provide the updates necessary to keep the app in conformity with the contract and inform you about available updates.

We are fully liable for intent and gross negligence, as well as for damages to life, body, and health. For slight negligence, we are only liable for breach of essential contractual obligations (cardinal obligations), limited to foreseeable, contract-typical damages.

We are not liable for data loss due to missing local backups, cloud service outages, or the accuracy of calculated training values.

9. Changes

We reserve the right to modify these terms. You will be notified in the app of material changes and asked to accept them again.

10. Privacy

Our privacy policy applies and can be viewed in the app under 'Privacy' and on our website.

11. Dispute resolution

We are not willing and not obliged to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).

12. App store notices (Apple / Google)

These terms constitute an agreement between you and Christian Geißler — not between you and Apple Inc., Google LLC, or any other platform operator. The platform operator is not obligated to provide maintenance or support for hitPR. Product warranty, third-party claims (including intellectual property), and compliance with applicable laws are the sole responsibility of the developer, not the platform operator. Apple Inc. and its subsidiaries are third-party beneficiaries of these terms and have the right to enforce them.

13. Authoritative language version

These terms are available in multiple languages. In the event of discrepancies between language versions, the German version shall prevail.

14. Final provisions

The laws of the Federal Republic of Germany apply. Should individual provisions of these terms be invalid, the validity of the remaining provisions shall remain unaffected. Mandatory consumer-protection provisions of the country in which you have your habitual residence remain unaffected.
