Watch Accuracy Tracker — Privacy Policy
Last updated: 2026-07-17
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
- This app does not require location, camera, or microphone access. It is a pure
tracking tool: the watches, readings, and offsets you enter are stored on your
device only and are never uploaded to us. The accuracy reference is your device
clock, which your phone keeps synced to network time; the app does not fetch
network time itself.
- 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
Drift rates in seconds per day are computed on-device from the offsets and timestamps
you record. Your watch collection and readings 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 tracking permission at any time in the iOS Settings
app; the app will continue to work with non-personalized ads.
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.

For any privacy question, contact the developer through the app's App Store listing.
