Privacy Policy for CalcBook

CalcBook is designed as an offline-first calculator and study toolkit. Core calculator, formulas, settings, and offline study features can work without account login.

The app may use third-party services such as Google AdMob, Firebase Analytics, and Firebase Crashlytics to support ads, improve app quality, and understand crashes.

CalcBook does not upload hidden vault files to cloud storage unless a future backup feature is clearly added and enabled by the user.
