Privacy Policy
The short version
Your photos, posture estimates and journal never leave your iPhone. We collect limited activity data to improve the app and to learn which ads work. You can switch analytics off in Profile and erase everything at any time.
What stays on your iPhone
Progress photos, the posture estimates made from them, your journal entries, your name if you enter one, your plan and your session history are stored only on your device. Photos are encrypted at rest and excluded from backups. They are analysed on the device using Apple's Vision framework and are never uploaded to us or anyone else.
What we collect
Usage activity. If usage analytics is on, we record events such as sessions completed, onboarding answers (for example what you want to work on) and screens reached, under a random ID rather than your name. Our analytics provider also receives your device model, system version, language, time zone and an approximate location derived from your internet address.
Purchases. Subscriptions are processed by Apple. We use RevenueCat to check and restore your subscription; it receives a random app user ID and your purchase status.
Advertising attribution. If you allow tracking in Apple's prompt, AppsFlyer receives your device's advertising identifier so we can tell which ad led to an install, and shares install and subscription events with the ad networks we use (Meta and TikTok). If you decline, only Apple's privacy-preserving, anonymous install reports are used.
What we don't do
We don't sell your personal information. We don't collect your photos, face or posture measurements, journal text, contacts or precise location. The app has no accounts, so we don't hold your email or password.

Health and safety
Chin-up offers general wellness exercises. The numbers from your photos are estimates, not medical measurements, and nothing in the app is medical advice.
Children
Chin-up is not directed at children under 13 and we do not knowingly collect their data.
Changes and contact
We will update this page and the copy in the app when the policy changes. Questions or requests: hello@hicupp.com.
