Heightly Privacy Policy
Last updated: July 14, 2026.
The short version
Heightly works on your device. The answers you give in the quiz — your age, height, family heights, and lifestyle habits — are stored locally on your phone and are used only to calculate your height estimate and build your plan. We do not sell your data.
What we collect
- Quiz answers and measurements you enter (age, sex, height, weight, parents' heights, lifestyle habits, goal height). Stored on your device.
- Purchase status. Subscriptions are processed by Apple (App Store) and our billing provider, RevenueCat. We receive an anonymous confirmation that a subscription is active — never your payment details.
- Anonymous usage analytics (which screens are used, crashes), only if you opt in. Analytics never include your measurements or quiz answers.
What we do NOT collect
- No account, email, or password is required to use Heightly.
- No photos, camera, or microphone access.
- No precise location.
- We do not sell or rent personal information to anyone.
Children and teens
Heightly is designed for teenagers and for parents tracking a child's growth. We do not knowingly collect personal information from children under 13 without parental consent. Because data stays on the device, deleting the app deletes the data.
Your choices
- Delete everything: delete the app, or use "Reset profile" in Settings.
- Analytics: opt out anytime in Settings.
- Subscriptions: manage or cancel in your Apple ID settings.
Health disclaimer
Heightly provides educational estimates and habit guidance. It is not a medical device and does not provide medical advice. Consult a doctor about growth concerns.
