Privacy Policy

SafeWall · Last updated 19 September 2026

SafeWall has no account, no server and no analytics. Everything it measures stays on your phone, and the only thing that ever leaves it is the receipt that proves you bought Pro.

What stays on your device

  • Your scan log: the gradient profile of each saved sweep, the targets found, the duration and any note you added.
  • Your calibration: the background field reading and the hollow-wall reference tap for the stud finder.
  • Your settings: language, wall profile, sensitivity, mains frequency, field unit, sound and vibration.
  • Your free scan counter.

All of this is written into the app's own storage on the device. It is not synchronised, it is not backed up to us, and it is deleted when you delete the app.

The microphone

The acoustic stud finder asks for microphone access, and only when you open that screen. While it is listening, audio is held in a short buffer in memory, measured, and overwritten by the next block of sound. No recording is created, nothing is written to storage, and no audio is transmitted anywhere. Leaving the screen releases the microphone immediately.

The magnetometer

Reading the magnetic sensor needs no permission on either platform. SafeWall uses it only while the radar screen is in front, and the readings are not stored except as the profile of a scan you chose to save.

What leaves your device

One thing: purchase verification. When you buy or restore Pro, RevenueCat receives a randomly generated user identifier, the store receipt, your country and the app version, so that your entitlement can be confirmed on your other devices. That identifier is not linked to your name, your email or your store account. The payment itself is processed by Apple or Google and we never see your payment details.

What we never collect

  • No name, email address, phone number or account.
  • No location, contacts, photos, calendar or health data.
  • No advertising identifier, and no advertising of any kind.
  • No analytics, no crash reporting, no usage tracking, no third-party trackers.
  • No audio recordings and no magnetic measurements.

SafeWall works completely in flight mode. Turning off your connection changes nothing except that purchases cannot be verified until it is back.

Children

SafeWall is not directed to children and we do not knowingly collect any data from them. It is a tool for adults doing work around the house.

Your rights

Under the GDPR and under Turkish law number 6698 (KVKK) you may ask what data relates to you, ask for a copy, ask for it to be corrected or erased, and complain to your supervisory authority. Because the app stores nothing about you on our side beyond the anonymous purchase record, most of these requests are answered by the fact that there is nothing to send.

Deleting your data

Delete the app and everything on the device goes with it. To have the anonymous purchase record removed, write to gelistirbizi@gmail.com from any address and say which store you purchased from; we action it within 30 days. Apple and Google keep their own transaction records under their own policies, and we cannot delete those.

Changes

If this policy changes, the date at the top of the page changes with it. A change that affects what leaves your device will be announced in the app before it takes effect.
