BOOTH BPM does not collect, store, or transmit any personal data.
The app uses the microphone only to analyze the tempo (BPM) of music playing nearby. Audio is processed in real time on your device and is discarded immediately. It is never recorded, saved, or transmitted. No audio leaves your device.
None. The app has no user accounts, no analytics, no advertising, and no third-party SDKs. It performs no network requests and works fully offline.
BPM and key values you choose to save, and your display preference, are stored on your device only. They are never sent anywhere. Deleting the app deletes them.
Readings sent from the Apple Watch app go directly to the paired iPhone over Apple's device-to-device connection. They do not pass through any server operated by us or anyone else.
The app is suitable for all ages and collects no data from anyone, including children.
If this policy changes, the updated version will be posted on this page with a new date.
