Data Collected
Tabbed Calculator does not sell or share personal information. The app does not contain advertising or analytics SDKs and does not request sensitive device permissions.
Optional Pro Purchase
The app offers an optional one-time Pro purchase through Google Play. When a user chooses to purchase or restore Pro, the app communicates with Google Play to display available purchase options and process the transaction. Google Play handles payment information and purchase processing under Google's privacy policies; the developer does not receive payment-card information.
To confirm a Pro entitlement, the app sends the Google Play purchase token to the developer's verification service. The service validates and acknowledges the purchase with Google Play, returns only the entitlement result to the app, and does not retain the purchase token or create a user profile.
Local Storage
Calculator tabs, expressions, memory values, and calculation history are stored only in the app's private storage on the user's device. Android may include this data in a cloud backup or device-to-device transfer when the user has enabled those Android features. The developer does not receive or access that backup data.
Removing Your Data
Users can remove individual tabs, clear a tab's history, or clear all app data through Android system settings. Uninstalling the app removes its local data, subject to any backup retained by the user's Android backup provider.
Changes to This Policy
This policy may be updated when the app's functionality or legal requirements change. The current policy will remain available from the app's download page and Google Play listing.
