When registering, we collect your name and mobile number. OTP verification is required for login and security. You will not share any OTP on any mobile number.

Your financial data and transactions are stored locally on your device and synced securely to our server when you are connected to the internet.

3. Data Loss and Backup

If you uninstall the app or clear app data manually, your local data will be deleted. Online backups are maintained for data recovery unless you request deletion.

4. Data Usage

Data is used only for functionality like calculations, transaction tagging, and Excel export. We do not share your data with any third-party advertisers.

5. Security

We use OTP-based authentication and secure data encryption. No sensitive data is shared without your permission.

The app may ask for permission to access storage (for Excel export) and internet (for data sync). No other device data is accessed.
