Privacy Policy

FormCheck · Last updated: 15 September 2026

In short: FormCheck collects no personal data. No account, no ads, no analytics. Camera frames are analysed on your device and discarded in the same instant. Not one of them is ever saved or sent anywhere.

1. Overview

FormCheck analyses your exercise technique using your phone’s camera and a pose model that runs on the device. There is no account, no sign up, no advertising and no analytics or behavioural tracking. The model is inside the app, so everything except purchase verification works with no internet connection at all.

2. Camera

The camera is active only while you are on a training screen and only with your permission. Each frame is passed to the pose model in your device’s memory, reduced to a list of joint coordinates, and discarded in the same instant. No photo is taken, no video is recorded, nothing is written to storage and no frame is ever sent anywhere. There is no setting that changes this, because there is no code that could.

What survives a frame is a set of numbers: angles and positions. Even those are not kept per frame; only the summary of a finished repetition is stored, and only on your device.

3. Data that stays on your device

All of the following is stored only on your own device, in the app’s own storage. It is not uploaded to us or to third parties, and we cannot see it:

  • Which exercise you did, when, and for how long
  • How many repetitions were counted, and for held positions how long the position was held
  • For each repetition: how much of the movement’s range you reached, how long the repetition took, its form score and which rules were triggered
  • Your settings: language, voice coach on or off, speaking speed, haptics, preferred camera, whether the skeleton and angles are drawn

The app keeps at most the 500 most recent sessions. Deleting the app from your device deletes all of it, and you can also erase everything from Settings.

4. Fitness information

Your session results say something about your body and your training, and in some jurisdictions that counts as health related information. It never leaves your device. It is not sent to us, not stored in any cloud, not shared with the stores or with RevenueCat, and there is no connection to Apple Health or Google Fit. Because it is local only, it does not move to a second phone and it is not in any backup we control.

5. Requests that leave your device

Only the following use an internet connection. Everything else is offline:

  • Verifying and restoring a Pro purchase, through RevenueCat and your store
  • Opening this privacy policy, the terms or the support page in your browser

The standard access logs of those servers (such as IP addresses) are subject to their own privacy policies.

6. Purchases

The optional Pro purchase is processed by the Apple App Store or Google Play. RevenueCat is used to verify purchase status and receives an anonymous identifier generated for your installation, along with the receipt from the store. It does not receive your name, your email address or anything about your training. We never have access to your payment card details. See the RevenueCat, Apple and Google privacy policies.

7. What the app does not do

The app sends no notifications. It does not access your location, contacts, microphone, photo library, calendar or health records. It contains no advertising SDK, no analytics SDK and no crash reporting SDK.

8. Children

The app is not directed at children and does not knowingly collect data from children. Training without supervision is not appropriate for young children in any case.

9. Your rights (GDPR and Turkish KVKK)

Because your personal data never reaches us, we hold no record to erase, correct or export. You can still write to us with any question about your rights under the GDPR or Turkish law no. 6698, and we will explain what is held where. To delete everything on your device, erase your sessions in Settings or delete the app.

10. Changes

If this policy changes, the date above is updated. Any change affecting how data is processed will be announced inside the app.
