Privacy Policy
Last updated: November 3, 2026
Scratch is an Android DJ application developed by Tasos Kleisas as a Bokontep music project. This policy describes how the Scratch Android app handles information on your device and through Google Play services.
Summary: Scratch does not collect, transmit, sell, or share personal data. It has no accounts, ads, analytics, crash reporting, or third-party tracking. Library metadata, queues, settings, FX chains, and decoded audio caches stay on your device. The app has no network permission.
No account or personal profile
Scratch does not require an account, sign-in, email address, or personal profile. The application does not include advertising, analytics, crash-reporting, or third-party tracking SDKs, and it does not send telemetry to the developer.
Data kept on your device
To provide its features, Scratch stores the following locally on your device:
- Audio-library metadata (titles, artists, albums, durations, file references, BPM values) in a local SQLite database.
- Deck queues, queue presets, EQ presets, autoplay, and crossfade settings.
- Per-deck and master FX chain state, including order, enabled effects, and parameters.
- Decoded PCM audio caches so tracks can be played and scratched without re-decoding.
This information is used only inside the app. It is not uploaded by Scratch. You can remove it by clearing the app's storage in Android settings or by uninstalling the app.
Data collection and sharing
- No personal information is collected.
- No account or sign-in is required.
- No analytics, advertising, crash-reporting, or tracking SDKs are included.
- No data is sold or shared with third parties.
- Scratch does not request the Android internet permission.
Permissions
Scratch requests only the permissions needed to read your local audio library:
- Read media audio (Android 13 and later) lets Scratch read audio files you choose to load and play.
- Read external storage (Android 12 and earlier) provides the same local audio-library access on older Android versions.
These permissions are used only to read audio files for playback. Scratch does not modify or upload your library, and it does not request microphone, camera, location, contacts, or photo access.
Android backups
If Android's system backup is enabled on your device, the operating system may include app settings and app data in your device backup. That backup is controlled by Google and your device settings, not by Scratch. The developer does not receive or have access to those backups.
Third-party components
Scratch uses open-source libraries including Oboe, AndroidX/Compose, and YAWN DSP. These libraries run locally and do not collect personal data on behalf of Scratch. Their licenses are included in the app's source distribution.
Children's privacy
Scratch is a general-purpose music tool and is not directed at children under 13. Because the app collects no personal data, it does not knowingly collect information from anyone, including children. The app contains no ads, purchases, or social features.
Changes
If this policy changes, the updated version will be published on this page with a new update date. Material changes will be reflected before the relevant app release.
