Stature ("we", "us", "the app") is a height-tracking and growth-estimate app published by İsmail Karakaş. This policy describes what information the app collects, how it's used, and who it's shared with. It applies to the Android and iOS versions of Stature.
Stature does not ask you to sign up, and does not collect your name, email address, or phone number to use the app. On first launch, the app generates a random device identifier and an anonymous authentication token (see Third parties) purely to keep your local data stable between sessions and to correlate crash reports — neither is tied to your real-world identity.
| Category | Examples | Where it lives |
|---|---|---|
| Growth profile | Age, sex, current height, family height reference, sleep / activity / nutrition answers, measurement history | On your device only. Never uploaded to a Stature server — we don't operate one. |
| Usage analytics | Screens viewed, features used, app-open events — no profile values attached | Firebase Analytics (Google), tied to an anonymous device ID |
| Crash & performance data | Stack traces, device model, OS version | Firebase Crashlytics (Google) |
| Purchase data | Subscription status, plan, purchase token | RevenueCat and the Google Play / App Store billing system |
We do not collect photos, contacts, location, or precise identity information at any point.
Your growth profile and measurement history live in local app storage on your device. Uninstalling the app deletes this data permanently — we have no copy to restore it from. Anonymous analytics and crash events are retained by Firebase per Google's standard retention windows (typically up to 14 months for Analytics).
Stature is intended for a general and teen audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with data through analytics identifiers, contact us and we will delete it.
Height and growth estimates in Stature are statistical projections for informational purposes only. They are not a medical diagnosis and don't replace advice from a pediatrician or healthcare provider — especially if you have concerns about growth, puberty, or development.
We rely on your device's built-in app sandboxing to protect locally stored data, and on Firebase's and RevenueCat's own security practices for the limited data sent to them. No method of transmission or storage is 100% secure, but nothing here is more sensitive than typical fitness-app data.
If this policy changes, we'll update the effective date above and, for material changes, surface a notice inside the app.
