Privacy you can trust
We built Statistics Problem Solver Pro to help you learn — not to harvest your data.
No server image storage
Problem images are sent to our secure backend to be solved, then processed and discarded. We never store your solve images server-side.
No account required
No email sign-up. An anonymous device ID handles free-solve limits and subscriptions — it's not your name, email, or Apple ID.
Local history
Every solved problem is saved on your device in SwiftData. History, favorites, and preferences stay with you — and never leave your phone.
