Privacy policy

Last updated 18.10.2026

In short: Crash Bang Clang does not collect personal data. There are no accounts, no ads, no analytics and no tracking. Progress is stored on the iPad and, if iCloud is on, in the family's own iCloud.

Who is responsible

Crash Bang Clang is published by Ryan Bartram, Thurgau, Switzerland. Contact: hello@crashbangclang.com.

What stays on your device

Player names, stars, practice time and settings are stored on the iPad. If iCloud is turned on, the same data is synced through your own iCloud account (Apple's key-value storage) so it appears on your other iPads. We cannot see or access it.

Microphone

If you allow it, the microphone is used to hear drum hits and stick clicks for timing. The sound is analysed on the iPad in real time. Nothing is recorded, stored or sent anywhere.

Apple Music

If you choose to play along to a song, Crash Bang Clang asks Apple for permission to use Apple Music. Searches and playback go directly to Apple under Apple's privacy policy. We do not receive your Apple Music account details or listening history.

Song tempos

When a song is played, Crash Bang Clang may look up its tempo. The song title and artist are sent to our server, which asks GetSongBPM.com. No personal data is sent with the request. Our hosting provider (Vercel) keeps standard technical logs, including the IP address, for a short time to run the service.

Purchases

Subscriptions are handled by Apple. We only learn from Apple whether a subscription is active on this device; we never see payment details.

Children

Crash Bang Clang is designed for children and families. We do not collect personal information from children. Links out of the app, purchases and settings sit behind a parental gate.

Deleting data

In the app, open Parents and choose "Delete all data on this device and in iCloud". Deleting the app removes the data on the iPad.

Your rights

Under the Swiss Federal Act on Data Protection and, where it applies, the EU GDPR, you can ask what data we hold about you. As we do not collect personal data, there is usually nothing to report, but you are welcome to write to us. You can also complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC).

Changes

If this policy changes, the new version will be published on this page with a new date.
