Privacy Policy

Last updated: March 17, 2026

Calculator: History & Money ("we", "our", or "the app") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our Android application.

Information Collection and Use

Calculator: History & Money does not collect, store, or transmit any personal information or data from your device to external servers. All calculations, history, and settings are stored locally on your device only.

Data Storage

All your data — including calculation history, time records, money calculator inputs, and app preferences — is stored exclusively on your device. This data never leaves your device and is not accessible to us or any third parties.

Advertising

The free version of our app may display advertisements provided by third-party ad networks (such as Google AdMob). These ad networks may collect certain non-personal information (e.g., device type, OS version, ad interaction data) in accordance with their own privacy policies. Upgrading to Premium removes all ads.

Data Security

Since all personal data is stored locally on your device, the security of your information depends on your device's own security measures. We recommend using device passcodes, fingerprint locks, or facial recognition to protect access to your device and the app.

Your Rights

You have complete control over your data within Calculator: History & Money, including:

• The ability to view all your calculation history and time records stored in the app
• The ability to edit or delete any entries
• The ability to completely remove all data by clearing the app's data or uninstalling the app

Third-party Services

Aside from the optional ad network in the free version, we do not integrate with any third-party services that collect personal data. The core calculator and money tools function completely offline and independently.

Children's Privacy

Our app does not knowingly collect personal information from children under 13. The app is suitable for general audiences and does not require any account creation or personal data submission.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. Continued use of the app after any changes constitutes your acceptance of the new Privacy Policy.
