PlateMath privacy
Fourdot Tech LLC does not receive your target weights, equipment, profiles, current load, preferences, or backup content through PlateMath.
Calculator and backup data
PlateMath stores calculator and equipment data in app-private storage on your device. Import reads only a document you choose; export writes only to a destination you choose. PlateMath has no account system or application backend. If you share an export, Android passes it to the destination you select, which handles it under its own privacy practices.
Calculations, equipment storage, plate changes, import, and export work offline. Android backups and destination apps may handle data under their own policies.
Ads, analytics, and diagnostics
PlateMath shows no ads and does not include Google Mobile Ads, UMP, Firebase Analytics, or Crashlytics in v1. PlateMath does not send app interactions, diagnostic reports, or crash reports to Fourdot. The app does not ask for your date of birth or collect your age.
Permissions and local use
PlateMath does not request dangerous runtime permissions. Your calculator and equipment data remain in app-private storage unless you choose to export or share a backup.
Google Play purchases
Google Play processes optional Lifetime Pro purchases and payment details. PlateMath receives purchase status and a purchase token from Google Play to unlock and acknowledge the purchase. These purchase details are used for app functionality and are not sent to a Fourdot server. Fourdot does not receive your card details. Google handles purchase records and refunds under Google's privacy policy.
