Privacy Policy
Ring Sizer is designed so the measurements you create stay on your device. This policy explains the limited data used to operate, improve, and support the app.
Measurements and local data
Ring and finger measurements, calibration values, saved measurement history, and labels you enter are stored locally on your device. Ring Sizer does not intentionally upload those measurement values or labels to Firebase Analytics or Crashlytics. You can remove saved measurements in the app, and uninstalling the app removes its local app data subject to iOS backup and restore behavior.
Firebase services
Firebase Analytics. The app may record important product events such as onboarding progress, which measurement method is used, measurement completion, paywall views, purchase/restore outcomes, and major feature usage. These events are designed not to include your actual ring diameter, circumference, ring size, or saved label.
Firebase Crashlytics. Production builds may send crash reports, stack traces, app version, device/OS diagnostics, and non-fatal error context so reliability problems can be fixed. We do not intentionally attach ring measurements or user-entered labels to crash reports.
Firebase Remote Config. The app fetches configuration values such as feature flags, review-prompt thresholds, and support/legal URLs. Standard app/device and network metadata may be processed by Firebase to deliver this service.
Firebase Hosting. This support site is served by Firebase Hosting. Google/Firebase infrastructure may process standard web request information such as IP address, browser details, and request logs for security and delivery.
Purchases
Purchases are processed by Apple. Ring Sizer also uses RevenueCat to load purchase offerings and determine whether Lifetime Access is active. RevenueCat and Apple may process purchase, entitlement, app/device, and store-related identifiers under their respective policies. Ring Sizer does not receive your full payment card details.
Advertising and game-economy data
Ring Sizer currently does not include an advertising SDK, credits, hints, lives, rewarded ads, levels, or an ad economy. Remote Config contains reserved disabled keys for those concepts so future behavior cannot become active accidentally without corresponding app code and disclosure updates.
Sharing and sale of data
Ring Sizer does not sell personal data. Limited service data is processed by Apple, Google/Firebase, and RevenueCat only as needed for the functions described above or as required by law.
Children
Ring Sizer is a general-purpose sizing utility and is not designed to knowingly collect personal information from children.
Changes
If the app’s data practices materially change, this policy will be updated before or alongside the relevant app change.
