Privacy Policy

Note: this English version is authoritative. Confirm the exact legal form (Einzelunternehmen vs. registered company) and have a Swiss-qualified lawyer review before publishing.

In one sentence: CoverDrift is a client-only app with no server of its own: it does not collect, transmit to us, sell, or share your personal data; there are no ads and no analytics/tracking. Your credentials and music stay on your device and with your own cloud provider.

1 · Who we are

This policy explains how the CoverDrift app for Android TV / Google TV (the “App”) handles data. The controller responsible under the Swiss Federal Act on Data Protection (FADP/revDSG) and, where applicable, the EU General Data Protection Regulation (GDPR) is Markus Heiniger (aibrain71), Switzerland.

2 · What data the App handles, and where it goes

The App has no backend. Data is processed on your device or sent directly from your device to the third parties you connect to.

DataPurposeStored whereSent to
OAuth access & refresh tokens for your cloud accountKeep you signed in; read your musicEncrypted on the device (Android Keystore / EncryptedSharedPreferences). Never sent to us.Microsoft (to obtain/refresh the token)

App settings (language, theme, favourites, trial/purchase status)App functionalityOn device only

The App requests read-only access to your files (Files.Read). It cannot modify or delete your cloud content.

3 · What we do NOT do

4 · Legal bases (GDPR, where applicable)

Processing is necessary to perform the contract with you and provide the App's core function (Art. 6(1)(b) GDPR). Under the Swiss FADP, processing is limited to what is necessary to provide the service you request.

5 · Third-party services

The App interacts directly with Microsoft (OneDrive / Microsoft Graph) for sign-in and your files, and with Deezer and Apple for cover/metadata lookup. These parties process data under their own privacy policies, which we do not control:

6 · Retention and deletion

Tokens and caches are stored only on your device. Remove them any time by signing out in the App (clears the tokens) or uninstalling the App (removes all App data). You can also revoke the App's access from your Microsoft account security settings. Because we hold no data on a server, there is nothing for us to delete on our side.

7 · Security

OAuth tokens are stored encrypted at rest using Android Keystore-backed EncryptedSharedPreferences. All network communication uses HTTPS/TLS. No system is perfectly secure, but the App minimizes risk by keeping data on the device and running no server.

8 · Children

The App is intended for a general audience and is not directed at children. We do not knowingly process children's data.

9 · International users

The App is offered internationally (including the USA, Europe, Asia, and Switzerland). Because processing happens on your device and directly with the services you choose, your data is handled by those services in the regions they operate. The controller is established in Switzerland.

10 · Your rights

Subject to applicable law (FADP / GDPR / your local law), you have rights to access, rectification, erasure, restriction, objection, and data portability. As we store no personal data on our own systems, these rights mainly concern data held by the third-party services above; for questions about the App, contact us at aibrain71@gmail.com. You may also lodge a complaint with your competent data-protection authority (in Switzerland: the FDPIC).

11 · Changes

We may update this policy. Material changes will be posted at this URL with a new effective date.
