Terms of Service

1. Scope

These terms apply to the use of the hitPR app, operated by Christian Geißler, Frankfurt am Main, Germany; the full provider details are set out in the legal notice. By using hitPR you agree to these terms. There is no user account — hitPR runs without registration.

Use of the app is permitted from the age of 16. If you are under 18, please also read the section “Fitness notice” and the notes on purchases under “Subscriptions & one-time purchase”.

2. Use of the app

hitPR is a strength training app. All training features are free to use; individual additional features are paid (see “Paid features”).

You receive a non-exclusive, non-transferable, personal right of use. If you obtained the app through the App Store, it is limited to Apple-branded devices that you own or control and is governed by the usage rules set out in the Apple Media Services Terms and Conditions; access remains permitted for accounts associated with yours via Family Sharing, volume purchasing or Legacy Contact. The app content (exercise catalog, images, texts) is protected by copyright.

Reverse engineering, decompilation or abusive use — in particular circumventing access restrictions or automated bulk use — is not permitted, unless the law mandatorily allows it (in particular § 69d (2), (3), (5) and (7) and § 69e of the German Copyright Act).

If you switch on the data backup, hitPR connects to your own cloud storage at Google or Apple. You are responsible for that account's credentials and for the storage space available there.

3. Data backup

The automatic data backup is part of hitPR Pro. It backs up your training data: plans, workouts, sets, personal records and settings. Image files are not included: for a cover image you have chosen yourself, the backup only remembers where it is stored on your device, not the image itself — after a device change it will be missing.

The backup is encrypted on your device and only then placed in your own cloud storage — on Android in your Google Drive, on iOS in your iCloud. We operate no server for this and hold no copy. The key stays with you; without it or your recovery code the backup cannot be read, not even by us. Keep the recovery code separately: if it is lost together with the device, the backup can no longer be restored.

Whether a backup can be written depends on your cloud provider — for example on whether storage space is still available there. We cannot be answerable for that. Independently of this, you are responsible for making regular backups of your own (export in the settings).

4. Paid features

hitPR offers all training features for free. hitPR Pro extends the analysis period, unlocks the automatic data backup and unlocks the Wear OS Watch Companion.

All three run on your device: the extended analysis period and the Watch Companion need no connection to us, and the data backup writes to your own cloud storage. More on this in the section “Availability”.

5. Subscriptions & one-time purchase

hitPR Pro is available as a subscription (monthly or yearly) or as a one-time purchase. The purchase is handled exclusively through the Apple App Store or Google Play.

Price, term, automatic renewal and cancellation follow from the respective store's offer at the time of purchase and are governed by its terms. For withdrawal and refunds, the section “Withdrawal” applies.

With the one-time purchase all Pro features remain usable permanently. It does not renew and is not charged again.

You can cancel your subscription at any time in the settings of the store you bought through; it then runs until the end of the paid period. If you bought through Apple, for technical reasons the cancellation must be made no later than twenty-four hours before the end of the period — otherwise it renews once more.

If you are not yet 18, a purchase may require the consent of a parent or guardian.

Statutory rights of withdrawal and warranty remain unaffected.

hitPR Pro is sold exclusively through the Apple App Store and Google Play; there is no direct sale. The usage contract for the app exists between you and us. Ordering, payment, term, renewal, cancellation and refunds run through the store you bought in and are governed by its terms.

For distance purchases there is a statutory right of withdrawal of fourteen days. For digital content not supplied on a tangible medium, it expires early when four things come together: performance has begun, you have expressly consented to the early start, you have acknowledged that you thereby lose your right of withdrawal, and you have been provided with a confirmation of the contract on a durable medium. For a purchase in a store these conditions are typically met; whether all of them are present in an individual case depends on the process of the respective store.

How withdrawal and refunds work for purchases made through the stores: Withdrawal and refunds

Apple and Google accept withdrawal declarations themselves under their own terms and confirm their receipt. Where to turn is set out at hitpr.app/en/withdrawal — we keep the routes up to date there. Refunds are handled through the store you bought through. If you have questions, [email protected] is happy to help.

6. Availability

hitPR runs on your device. There is no cloud service of ours whose shutdown could take away your data or purchased features: your data rests with you, and the data backup writes to your own cloud storage.

Only ancillary services are operated by us — delivery of the plan catalog and the exercise images, the feedback function and the anonymous usage statistics. If they fail or we discontinue them, the app remains fully usable with the catalog already downloaded, including the extended analysis period, the data backup and the Wear OS Watch Companion.

Should we discontinue the development of hitPR, we will announce this in the app at least six months in advance. Until then the export in the settings remains available so that you can back up your data in full. Your purchased features remain usable after that too — they run on your device and need no connection to us; there will simply be no further updates.

7. Deleting your data

You can delete your data at any time in the settings (“Delete All Data”). This removes all local data on the device: training history, sets and personal records, plans and folders, custom exercises and your app settings. If the data backup is active, the backup file in your cloud storage is deleted as well. Only the bundled exercise catalog remains.

Not covered are copies outside the app: export files you have passed on yourself, and copies in a backup made by your operating system. If you want to keep your data, back it up beforehand using the export.

Since there is no user account, there is nothing you need to cancel or have deleted with us. How to have feedback messages deleted is described in the Privacy Policy under “Your rights”.

8. Fitness notice

hitPR is software for recording and planning strength training for healthy adults. It does not serve the diagnosis, prevention, monitoring, prediction, prognosis, treatment or alleviation of disease or injury. 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 ACSM Position Stand on resistance training (2026) and general sports science and are estimates — not individual training or health advice. Sports science continues to develop; we do not promise that the content always reflects the latest state of research.

You are responsible yourself for performing the exercises, for choosing the training weights and for judging your physical capacity. Using the app and following training suggestions is at your own risk.

Seek medical advice before you start training if you have joint problems, past surgery, cardiovascular disease, neuromuscular disease, asthma or other respiratory conditions, or any other health limitations. The same applies during pregnancy and while breastfeeding. If you are under 18, talk to a parent or guardian before taking up strength training, and to your doctor if in doubt.

If an exercise causes pain, leave it out or replace it. If a suggested weight or repetition count seems too high, reduce the values — the suggestions are guide values, not requirements.

Sets taken close to muscular failure (RIR 0, AMRAP) belong, with free weights, near a rack or a training partner who can spot you.

9. Limitation of liability

The statutory rights in respect of defects in digital products (§§ 327 et seq. German Civil Code) apply to the app. Within the scope of our usage contract with you, we provide the updates necessary to maintain the app's 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.

Otherwise we are not liable for data loss caused by missing backups of your own, for outages or restrictions of the cloud storage you have chosen, or for the accuracy of calculated training values. Liability under the preceding paragraphs remains unaffected.

We do not promise that you will reach particular training goals with hitPR. The result depends on circumstances we do not control: your physical condition, your execution, your nutrition and your recovery. Claims under the German Product Liability Act remain unaffected.

10. Changes

Without your consent we may amend these terms if the legal situation or supreme court case law changes, if we correct editorial errors, or if the change affects neither our performance nor your consideration nor your rights under this contract.

Any other change only becomes effective towards you once you have agreed to it. If you do not agree, the version you last agreed to continues to apply to you.

Changed terms come with a new app version. On the first launch afterwards we show them to you and name what has changed. Without an update by you, the terms that apply to you do not change — they accompany your installed app version. We announce upcoming changes in advance on hitpr.app with the terms of service, together with the date from which they apply. You can view the current version in the app at any time.

11. Privacy

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

12. Dispute resolution

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

13. App store notices (Apple / Google)

These terms govern the use of the app and to that extent constitute a contract between you and Christian Geißler — not between you and Apple, Google or any other platform operator. Questions, complaints and claims concerning the app are therefore addressed to us; the name, address, telephone number and email address for this are set out in the legal notice. For the purchase of hitPR Pro, the notes on withdrawal and refunds apply.

The platform operator is under no obligation to provide maintenance or support for hitPR. For product warranty and for claims relating to the app, the developer alone is responsible, not the platform operator — this applies in particular to product liability claims, claims under consumer protection law, third-party claims (including intellectual property) and any claim that the app fails to conform to legal or regulatory requirements. Apple and its subsidiaries are third-party beneficiaries of these terms and have the right to enforce them.

If the app fails to conform to an applicable warranty, you may notify Apple; Apple will then refund the purchase price you paid for the app. To the maximum extent permitted by law, Apple has no other warranty obligation — we are responsible for all other claims arising from the failure to conform to a warranty. Your statutory rights in respect of defects under the section “Limitation of liability” remain unaffected.

When using the app you comply with applicable third-party terms of agreement — for example those of your mobile or internet provider and, if you switch on the data backup, those of your cloud storage. You also represent that you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as terrorist-supporting, and that you are not listed on any U.S. Government list of prohibited or restricted parties.

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.

For disputes arising from this contract, our seat is the place of jurisdiction if, at the time the action is filed, you have no general place of jurisdiction in Germany or in another member state of the European Union. The consumer's place of jurisdiction within the European Union remains unaffected.
