Terms of Use

Last updated: August 2026

Your license to use the ampulse app is governed by Apple's standard Licensed Application End User License Agreement. The terms below supplement it; where they conflict and you are a consumer, whichever term is more favourable to you prevails.

1. Provider

Rafael Klug, [Street and number], [Postal code, City], Germany — support@ampulse.fit. Your contract is with the provider only; Apple is not a party to it, but Apple and its subsidiaries may enforce these terms as third-party beneficiaries.

2. What ampulse is — and what it depends on

ampulse reads physiology from Bluetooth sensors you own — a Polar band for nights and days, chest straps and machines for training — computes its measurements on your iPhone, and stores everything there. Honest limits, so this description stays accurate:

• ampulse depends on your sensors answering. Bluetooth range, battery, firmware and Polar's device behaviour are outside ampulse's control.
• Readings can be delayed, missing or wrong. Thresholds and derived metrics are estimates from your own data, with the uncertainty that measurement carries.
• ampulse needs the permissions it requests — Bluetooth always, location only for outdoor runs — in order to work.
• iOS updates can change platform behaviour ampulse relies on.

Your statutory rights regarding digital products (including §§ 327 ff. of the German Civil Code) remain unaffected by anything on this page.

3. Subscription and trial

• ampulse is purchased through your Apple ID as an auto-renewing subscription (monthly or yearly). Price and term are shown in the app before you buy.
• A free trial, where offered, converts into a paid subscription unless cancelled at least 24 hours before it ends.
• Manage and cancel in your device settings under your Apple ID subscriptions. Billing and refunds are handled exclusively by Apple (reportaproblem.apple.com).

4. Right of withdrawal

For purchases through the App Store, your statutory right of withdrawal is handled within Apple's purchase flow.

5. Updates and availability

During your subscription term we provide the updates needed to keep ampulse in conformity with its description on current iOS versions. We may discontinue ampulse or individual features with reasonable advance notice; your statutory rights for the already-paid period remain unaffected — and your data, stored as plain files on your phone, remains readable either way.

6. Liability

The provider is liable without limitation for intent and gross negligence, and for damages resulting from injury to life, body or health. In cases of slight negligence, the provider is liable only for the breach of a material contractual obligation — an obligation whose fulfilment makes the proper performance of this contract possible at all and on whose fulfilment you may regularly rely — and such liability is limited to the damage typical for this kind of contract and foreseeable at the time of conclusion. Liability under the German Product Liability Act remains unaffected.

7. Health note

ampulse is a fitness instrument — a measurement and training tool, and neither a medical device nor a diagnosis, treatment or emergency service. Sensor readings can be delayed, missing or wrong. You are responsible for your own training; consult a physician before beginning any exercise program, and stop and seek appropriate medical help for concerning symptoms.

8. Governing law

German law applies. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of the country in which you habitually reside.

9. Dispute resolution

The provider is neither willing nor obliged to participate in dispute-resolution proceedings before a consumer arbitration board (§ 36 VSBG).

10. Changes to these terms

We may change these terms for valid reasons — such as changes in law or in the service — with notice on this page. Changes apply to future use; the version in force when you subscribed governs that subscription period.
