Privacy Choices and Data Deletion

1. Web analytics choice

Use the button below to reopen the cookie preference panel and allow or reject Google Analytics. After rejection, new analytics does not load and accessible analytics cookies are removed.

2. Mobile app and ads

• The mobile app does not use Firebase Analytics; only anonymous aggregate tool counts are retained.
• Where required for your region, reopen Google’s consent form with “Ad privacy options” in Settings.
• Manage device advertising identifiers and system-level personalization in Android or iOS settings.

3. Delete data on your device

• Clear calculation history from the History screen.
• Remove favorites by tapping the favorite icon.
• Clear website data or clear/uninstall the app. This also removes local language, theme, history and favorite choices.

4. Server data and requests

Because there are no user accounts, most local data is not linked to your identity. File jobs expire after 30 minutes and are automatically cleaned up. Send privacy requests to info@calcduo.com and include the approximate date, time, tool and device so a technical record can be located where possible.
