2. No Data Collection

HarmoniKeys is a 100% offline application. It collects, transmits and stores no personal data. The application requires no account, no sign-up and no server connection to work.

HarmoniKeys includes no advertising, analytics or tracking SDK (no Google AdMob, no Firebase, no advertising identifier). No information about your usage is sent to JIXTER or any third party.

3. Local Data

The only data generated by the application (preferences, progress, settings) is stored locally on your device. It never leaves the device and is deleted when you uninstall the application.

4. In-App Purchase

The single one-time purchase (€4.99) that unlocks all features is handled exclusively by the distribution platform (Google Play or App Store). JIXTER neither receives nor stores any payment data. The processing of these transactions is governed by the privacy policy of the relevant store.

5. Data Sharing

As no personal data is collected, no data is shared, sold or transmitted to any third party.

6. Your Rights

Since no personal data is processed by JIXTER, there is no data for us to access, rectify or delete on our side. For any privacy-related question, you may contact us at contact@jixter.fr.

7. Cookies

The HarmoniKeys application uses no cookies or similar tracking technologies.

8. Changes

This policy may be updated. Changes will be published on this page with the update date.
