Audio stays on your iPhone
Microphone audio is analysed on the device. It is never recorded or sent anywhere unless you tap Save recording, and saved recordings stay on your devices.
One network request
The only request Beat Error makes is to time.apple.com for atomic time. It carries no personal data.
Your data, your iCloud
Watches, readings, photos and time logs stay on your device, and in your own iCloud if you turn on sync. The developer cannot see them.
Beat Error collects no data: no identifiers, no usage statistics, no crash reports sent by the app, no advertising. Purchases are handled by Apple; the developer only receives Apple's anonymous sales totals. Questions about privacy: sanghuynhxuan@gmail.com
