Last updated: 7 August 2026 · App: Drift Analyzer · Developer: Kaan Sayın (4ES)
This Privacy Policy explains what information Drift Analyzer (“the app”, “we”) collects, how we use it, and your choices. By using the app you agree to this policy.
1. Information we collect
Account data: your email address (when you sign up with email, Google, or Apple). With Apple sign-in you may choose to hide your email.
Profile data: a username you choose and, optionally, a car model. These appear on leaderboards.
Location: we use your device location (precise and approximate) to record drive routes and to compute speed. Location is collected only while you are actively using the app — the app does not access your location in the background.
Driving & sensor data: motion-sensor (accelerometer/gyroscope) and GPS data used to detect drifts and compute drive statistics, routes and scores.
Purchase data: if you subscribe, our payments partner (RevenueCat) and the app store process the purchase and provide us a subscription status and an anonymous identifier. We do not receive your card details.
Diagnostic data: if the app crashes or encounters an error, an anonymous crash report (stack trace, device model, OS version, app version, locale and a session identifier) is sent to our error-reporting partner (Sentry). This does not include your email, name or precise location.
Advertising identifier & marketing measurement: the app includes Meta (Facebook) App Events so we can measure whether our advertising works. This sends your device's advertising identifier (Google Advertising ID on Android, IDFA on iOS) together with a small number of events — such as app install, account registration and purchase — to Meta. On iOS this only happens if you allow tracking when the App Tracking Transparency prompt appears. See “Your choices” below for how to limit or reset this.
2. How we use your information
To provide the core features: drift detection, route history, statistics, leaderboards and friends.
To manage your account and your Premium subscription.
To diagnose and fix crashes and errors (anonymous diagnostics).
To measure the effectiveness of our advertising (attribution and analytics).
3. Third-party services
Supabase — secure backend (authentication and database).
RevenueCat + Apple App Store / Google Play — subscription processing.
Google / Apple Sign-In — optional login providers.
Sentry (getsentry.com) — crash and error diagnostics.
Meta Platforms (Facebook) — advertising measurement and attribution, as described above.
We do not sell your personal data. We do share the advertising identifier and the marketing events listed above with Meta so that we can measure our advertising. We do not share your email address, your routes or your location data with any advertising network.
4. Your choices
Location: you can deny or revoke the location permission in your device settings. Drift detection and route recording will not work without it.
Advertising identifier: on Android you can reset or delete your advertising ID in Settings → Google → Ads. On iOS you can decline the tracking prompt, or turn off Settings → Privacy & Security → Tracking.
5. Data retention & deletion
We keep your data while your account exists. You can delete your account at any time from within the app (Profile → Delete account). This permanently removes your account, drives and all associated data from our servers.
If you no longer have the app installed, you can request deletion here: Delete your account.
6. Security
Data is transmitted over encrypted connections (HTTPS) and protected with row-level security so each user can only access their own data.
7. Children
The app is not directed to children under 13 (or the minimum age in your country). We do not knowingly collect data from children.
8. Your rights
You can access and update your profile in the app, and delete your account and data at any time. For other requests, contact us.
9. Changes
We may update this policy; the “Last updated” date will change. Continued use means you accept the updated policy.
