E6B Flight Computer — 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
- barometer / motion & environment sensor readings (used only on your device to compute a live density altitude from the phone's air-pressure sensor — these readings are not stored or transmitted). 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
Wind-triangle, crosswind, density-altitude, true-airspeed and fuel/time/distance
calculations are computed on-device from the values you enter and, for the live
density-altitude card, from the phone's barometer. Saved calculations 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 the calculation history 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
(the live density-altitude card falls back to manual altimeter and altitude entry).
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.
DISCLAIMER
This app is a training and reference calculator only. It is not certified for
operational flight use. Always confirm every value with official aeronautical data,
your aircraft's POH, and current weather before flight.
