2. This website (intervala.petkov-tech.de)

The site is hosted by a hosting provider. Technically necessary data may be processed to deliver the site and keep it secure (Art. 6(1)(f) GDPR). Server log files may include IP address, time, requested resource, transfer size, browser/OS, and referrer. No analytics cookies or tracking pixels are used on this product page. Email contact is processed only to handle your request.

3. The Intervala iOS app

Intervala is a local workout timer. In version 1.0:

• No accounts or sign-in
• No analytics or advertising SDKs
• Workout content is not uploaded to us

Workouts you create are stored only on your device. Uninstalling removes that data with the app (subject to normal device backups). Background audio is used so session sounds can continue when the screen locks. The app does not access camera, microphone, photos, location, contacts, or Health data.

Unlock is a one-time Apple In-App Purchase. Apple processes payment; we do not receive your card details. Entitlement follows your Apple ID (Restore Purchases). A local 30-day trial start date is stored in the Keychain on the device and is not sent to any server. After the trial, workouts remain on the device; access requires unlock.

4. Your rights

Under the GDPR you may have rights of access, rectification, erasure, restriction, objection, portability, and to lodge a complaint with a supervisory authority.

5. Changes

We will update this page when the website, app, or legal requirements change.
