Privacy Policy

VarioPulse · Last updated 19 September 2026

VarioPulse collects nothing. Your position, your pressure readings and your flight logs stay on your device.

1. The short version

There is no account, no login, no analytics, no advertising, no crash reporting and no tracking of any kind. The app works with the network switched off, which is the whole point of it.

2. What is read, and where it goes

  • Barometric pressure and motion. Read continuously while the app is open to compute altitude and vertical speed. Stored only as part of a flight you choose to record.
  • Location. Read while the app is in the foreground, with your permission, to compute ground speed, glide ratio, wind and your drift track. Written only to the flight database on your device.
  • Your settings. Language, units, thresholds, volume and QNH, stored in the app's own storage on the device.

None of this is transmitted anywhere. There is no server to transmit it to.

3. The one thing that does leave the device

If you buy VarioPulse Pro, the purchase is processed by Apple or Google and validated through RevenueCat. RevenueCat receives a randomly generated app user identifier, the store receipt, your country and the app version. That identifier is not your name, your email or your device identifier, and it is used only to know whether your Pro unlock is valid.

This happens only when you open the purchase screen or restore a purchase. If you never buy anything, nothing ever leaves your device.

4. No third party content

VarioPulse downloads no map tiles, no terrain data and no airspace files. The drift map is drawn from your own track, which is why it works with no signal.

5. Children

VarioPulse is aimed at adult pilots and sailors and is not directed at children. No personal data is knowingly collected from anyone, of any age.

6. Deleting your data

Delete a flight from the logbook to remove its track and telemetry permanently. Deleting the app removes the entire database and every setting. Because the publisher holds no copy, there is nothing further to request and no deletion form to fill in.

7. Your rights

Under the GDPR, the KVKK and comparable laws you have rights of access, correction, deletion and portability. Since all of your data sits on your own device and can be exported as IGC, GPX or CSV at any time, you exercise those rights directly. If you still want to write to the publisher: gelistirbizi@gmail.com

8. Changes

If this policy changes, the new version appears on this page with a new date at the top.
