beatviz privacy policy
Last updated: November 2, 2026
beatviz is an Android app that listens to music through your phone’s microphone and shows its beat. This policy explains what data the app uses and who receives it.
Microphone audio
beatviz uses the microphone only while it is listening, that is, between pressing START and STOP (it also stops when you leave the app). The audio is analysed on your phone to find the beat. It is not recorded, not stored and not sent anywhere, neither to us nor to anyone else.
Settings stored on your phone
beatviz stores a few settings on your phone, such as the display sync and whether you have seen the introduction slides, plus the anonymous purchase identifier and a cached copy of your purchase status (see below). The settings never leave your phone, and everything is deleted when you uninstall the app or clear its data.
Purchases
beatviz Pro is sold through Google Play. Purchases are processed by Google under the Google Privacy Policy; beatviz never sees your payment details.
To check whether you have beatviz Pro, the app uses RevenueCat, a subscription management service. RevenueCat receives:
- a random identifier created by the app, not linked to your name, email or Google account;
- your purchase history in beatviz (products, dates, prices, renewal and refund status, and the Google Play purchase token used to verify it);
- basic technical information: platform, Android version, app version, country and language settings.
RevenueCat does not receive your audio, location, contacts or any other personal information from beatviz. See the RevenueCat Privacy Policy. Data is encrypted in transit.
What beatviz does not do
beatviz has no user accounts, no advertising, no analytics and no tracking. It does not sell or share data with anyone other than Google Play and RevenueCat, as described above, and only for purchases.
Deleting your data
Uninstalling beatviz deletes everything stored on your phone. To have your purchase records deleted from RevenueCat, write to the email address below; your Google Play purchase history is managed by Google in your Google account.
Children
beatviz is not directed at children and does not knowingly collect personal information from them.
Changes
If this policy changes, the new version will be published on this page with a new date.
