AR Theodolite: Angle & GPS — 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
- precise location (GPS) (used only to display your live latitude/longitude, altitude and coordinate readouts (DMS, UTM, MGRS) and to geotag the readings you capture — used on your device; saved readings are stored on your device only).
- the camera (used only to show the live view that the theodolite HUD — the azimuth ribbon, pitch gauge and crosshair reticle — is overlaid on; the app does not record, save, or upload camera images).
- device motion and the compass/magnetometer (used only to measure the azimuth (heading) and pitch/elevation angle the phone is aimed at, which the HUD displays live).
- 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
Azimuth, pitch and coordinate conversions are computed on-device from the compass,
motion sensors and GPS. Captured readings, notes, and values are stored on your device
only. The camera feed is shown live as the HUD background and is never recorded or sent
anywhere. 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 camera, location, 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.
