Privacy Policy
Last updated: October 8, 2026
This Privacy Policy describes how your data is handled when you use the FormVision app for iOS and Android ("the App"). The App is developed and operated by Sebastian Golijow ("we", "us") under the YeKo Studio brand. By using FormVision you agree to the practices described here.
The short version: FormVision analyzes your videos on your phone. We also keep a copy of the videos you analyze so we can verify the results by hand and improve the tracking. You can turn it off anytime — in your profile on iOS, or with the “Share my analysis videos” switch on the home screen on Android.
1. Data we collect
Account data (iOS only, stored on your device):
- Name and email — provided by Sign in with Apple when you create your profile. This information is stored locally on your device; we do not operate servers that receive it.
- Age (optional) — entered by you, stored locally.
- Profile photo (optional) — chosen from your photo library, stored locally.
The Android app has no account or sign-in: it does not ask for your name, email, age, or photo.
Content you create: the videos you record for analysis, the analysis results (skeleton data, bar path, metrics, cues), your improvement plans, and your progress data are processed on your device and kept in the App's local storage. Unless you turn it off (in your profile on iOS, or with the “Share my analysis videos” switch on the home screen on Android), a copy of each analysis video and its results is also uploaded to our servers (hosted by Supabase in the EU) under an anonymous identifier. We use these copies only to check that the analysis was correct and to improve the tracking model. They are never shared, sold, or used for advertising, and are not linked to your name or email. On Android, uploads happen only over Wi-Fi, and turning the switch off also cancels any upload that has not been sent yet.
Roadmap votes and suggestions (iOS): if you vote for an upcoming feature or send a suggestion in the “What’s next” screen, that vote (or removal of a vote) and the text you write are stored on our servers (Supabase, EU) under the same anonymous identifier. We use them only to decide what to build next. Nothing is sent unless you tap a vote or send a suggestion, and suggestions are never published.
In-app activity (iOS): to understand where the App works well and where people get stuck, the iOS app also stores on our servers (Supabase, EU), under the same anonymous identifier, a log of what you do inside the App: the screens you open and how long you stay on each one, the in-app events we measure (for example, that an analysis was started or completed), and when the App goes to the background or comes back. It never includes your name, email, or the content of your videos. It is switched off together with video uploads (the same setting in your profile), and nothing is collected while it is off.
Purchase data: subscriptions and purchases are processed by Apple through your Apple ID on iOS, and by Google Play through your Google account on Android. To manage subscription status the App uses RevenueCat, which receives an anonymous app user identifier and purchase information from Apple or Google Play. RevenueCat never receives your name, email, or videos.
Usage and attribution data (iOS only): the iOS app uses AppsFlyer to measure installs and in-app events (for example, that an analysis was completed) so we can understand which of our own campaigns bring people to FormVision. If you allow tracking in the iOS prompt, this includes your device's advertising identifier; if you decline, only aggregated, non-identifying measurement is used. AppsFlyer never receives your name, email, or videos. The Android app does not use AppsFlyer and does not access your device's advertising identifier.
2. Data we do NOT collect
- We do not upload your videos if you have turned uploads off, and we never publish them.
- We do not track your location.
- We do not show third-party ads inside the App.
- We do not sell your personal data to anyone.
3. How your data is used
- To analyze your lifting technique and show you results. The analysis runs on your device; uploaded copies are used only for quality checks and to improve the tracking model.
- To build your improvement plan and track your progress over time.
- To maintain your profile and subscription status.
4. Third-party services
- Apple (iOS) — Sign in with Apple and in-app purchases, governed by Apple's own privacy policy.
- Google Play (Android) — app distribution and in-app purchases, governed by Google's own privacy policy.
- RevenueCat — subscription management (anonymous identifier and receipt data only).
- AppsFlyer (iOS only) — install and in-app event measurement for our own marketing (anonymous identifier; advertising identifier only if you allow tracking).
- Supabase — storage of analysis videos and results you have allowed us to keep, of roadmap votes and suggestions you send, and of the in-app activity log described above (EU servers, anonymous identifier only).
5. Data retention and deletion
Your data on your device is under your control:
- You can delete individual analyses and videos from within the App.
- Deleting the App from your device permanently deletes your profile, videos, analyses, and plans stored on it.
- On iOS, you can revoke Sign in with Apple access at any time from your Apple ID settings.
Uploaded videos and results are kept for up to 12 months and then deleted. You can turn uploads off at any time (in your profile on iOS, or with the “Share my analysis videos” switch on the home screen on Android), and you can ask us to delete what we already hold by emailing support@formvision.app — on iOS, from the App (Profile → Support) — and we will delete every video, result, vote, suggestion and activity record tied to your anonymous identifier. Deleting the App does not by itself delete copies already uploaded; email us for that.
6. Children
FormVision is not directed at children under 13, and we do not knowingly collect data from them.
7. Health data
FormVision analyzes movement in your videos to give technique feedback. It does not diagnose medical conditions, does not read data from HealthKit or Health Connect, and does not write to them.
8. Changes to this policy
We may update this policy as the App evolves. Material changes will be announced in the App before they take effect.
