How calculations work
Calculations are performed on the device. The values you enter, calculation results, saved calculations, scenario names and notes are not sent to a server operated by us.
Information stored on your device
The app may store the following information locally:
- theme, currency and number-format preferences;
- favourite and recently used calculators;
- calculation history and saved calculations;
- comparison scenarios and rewarded-feature access;
- advertising frequency and consent-related state.
You can clear calculation history, delete individual saved calculations and reset preferences from the app's Settings screen. Removing the app may also remove locally stored information, depending on the device's backup settings.
Advertising and consent
The app uses Google AdMob. Google may process device information, advertising identifiers, approximate location derived from an IP address, ad interactions and diagnostic information for advertising, measurement, fraud prevention and consent. The information processed depends on device settings, region and the choices available to you.
Where required, Google's User Messaging Platform presents a consent message or privacy options. The app provides a “Privacy choices” option when the Google SDK indicates that it is required or available.
Learn more in Google's Privacy Policy and Google's information for AdMob users.
Firebase Analytics
Firebase Analytics may collect non-sensitive information about feature use, such as which calculator was opened, whether a calculation was completed, the screen viewed, the type of export used and the placement of an ad impression.
Custom analytics events do not include revenue, costs, prices, investments, saved calculation contents, custom names, notes or full calculation results.
Firebase Crashlytics
Firebase Crashlytics may collect crash reports, stack traces, app and operating-system versions, device model and other diagnostics needed to identify and fix app problems.
Network access and offline use
Core calculations work offline. An internet connection may be used for advertisements, consent messages, analytics, crash reporting and links you choose to open. If these services are unavailable, the calculators continue to work.
Children
The app is a general business utility and is not directed to children. We do not knowingly ask users to provide personal information through an account or profile.
