Fan Balance: Vibration — Privacy Policy
Last updated: 2026-07-11
This app is built to respect your privacy. We do not sell your personal data, and
your content stays on your device. This policy explains the limited data the app uses.
INFORMATION THE APP USES
- motion and accelerometer data (used only on your device to measure the vibration of your ceiling fan or other rotating machine so the app can help you find the unbalanced blade; readings are not saved to our servers).
- This app does not require location, camera, or microphone access.
- anonymous diagnostics and crash reports (via Google Firebase Analytics and Crashlytics) to keep the app stable.
- an advertising identifier and related data used by Google AdMob to show ads. On iOS, the app asks for your permission via App Tracking Transparency (ATT) before any tracking, and uses Google's UMP consent flow to honor GDPR/EEA choices. You can decline tracking and the app keeps working with non-personalized ads.
HOW IT IS USED
Vibration is computed on-device from the accelerometer, with the constant gravity
component removed, and shown as an approximate RMS value. Any measurements and
settings you create are stored on your device only.
We use the data above only to provide the app's features, to keep the app stable,
and (with your consent) to show ads. We do not build advertising profiles ourselves
and we do not upload your content to our servers.
DATA RETENTION & YOUR CONTROL
Settings and content you create are stored on your device and are removed when you
delete the app. You can revoke motion or tracking permissions at any time in the iOS
Settings app; the app will continue to work with reduced features.
THIRD-PARTY SERVICES
The app may use: Google Firebase (Analytics, Crashlytics) and Google AdMob (ads).
Their handling of data is governed by their own privacy policies.
CHILDREN
This app is not directed to children under 13 and does not knowingly collect personal
information from children.
CONTACT
For any privacy question, contact the developer through the app's App Store listing.
