How can we help?
Use these steps for the most common Ring Sizer questions. This page intentionally does not publish an unverified email address.
Measurement looks wrong
- Open Settings → Recalibrate Screen.
- Use a standard ID-1 payment card only as the calibration reference.
- For ring-on-screen measurement, place the ring flat and match the inner edge.
- Repeat the measurement and compare results before ordering.
Restore Lifetime Access
Open Settings → Restore Purchases while signed into the Apple ID that made the purchase. Apple handles the transaction; the app uses RevenueCat to refresh the entitlement.
Your data
Saved measurement values and labels are stored on-device. See the Privacy Policy for Firebase diagnostics/analytics details.
Direct support
A verified support email has not been configured in the production project yet, so the app opens this support page rather than exposing a placeholder address. Before App Store submission, the developer should add the verified support email to Firebase Remote Config or the App Store listing. Until then, purchase/refund issues can also be handled through Apple’s purchase support channels.
When contacting support
Include the app version, iOS version, device model, measurement method, and a description of the issue. Do not send payment card details or other sensitive information.
