**Last updated:** February 5, 2025
This Privacy Policy describes how the Calculator app ("we", "our", "the app") handles information when you use our application on Android (Google Play) or other platforms. By using the Calculator app, you agree to this policy.
1. Overview
The Calculator app is a utility application that provides basic and scientific calculation, calculation history, and unit conversion. We are committed to protecting your privacy. This policy explains what data we collect (if any), how we use it, and your rights regarding your information.
2. Information We Collect
**We do not collect, store, or transmit any personal data to our servers or third parties.**
**Calculation history:** Expressions and results are kept only in your device’s memory (RAM) during the current app session. This data is not sent to any server, not stored on disk in a way that we access, and is lost when you close the app or clear history from within the app.
**Unit converter:** Values you enter and conversion results exist only in the app’s local state on your device and are not collected or transmitted.
**No account required:** The app does not require registration, login, or any account. We do not collect names, emails, or other identifiers.
**No usage analytics:** We do not use analytics SDKs (e.g. Firebase Analytics, Google Analytics) to track how you use the app.
**No advertising:** The app does not show ads and does not use advertising SDKs that would collect data for ad targeting.
3. Data Storage and Retention
**On-device only:** Any temporary data (e.g. calculation history during a session) stays on your device.
**No cloud storage:** We do not store your calculations or any other data on our or third-party servers.
**Clearing data:** You can clear calculation history at any time via **Settings → Clear calculation history** or from the **History** screen. Uninstalling the app removes all app data from your device.
4. Third-Party Services and Data Sharing
We do not sell, rent, or share your data with third parties for marketing or advertising.
The app may use standard device features that interact with third-party services only when you choose to use them:
**Share app: When you tap "Share app" in Settings, your device’s share sheet is used. We do not receive or store what you share or with whom.
**Rate app: When you tap "Rate app", your device opens the Google Play Store (or App Store) page. We do not collect any data from this action.
**Contact us: When you tap "Contact us", your device opens your email app to send a message to us. We only receive what you voluntarily send in that email.
We do not use analytics, crash reporting, or advertising SDKs that would collect or share your data.
5. Permissions
The Calculator app uses only the permissions necessary for its features (e.g. if the app uses network for opening store links or email, such access is limited to actions you initiate). The app is designed to work **offline**; no background data collection is performed.
6. Children’s Privacy
The app does not knowingly collect any personal information from children. The app is suitable for general use and does not target children under 13. If you believe a child has provided us with personal information, please contact us and we will address it.
7. Data Security
Because we do not collect or transmit your data to our servers, there is no risk of your calculations or usage being exposed through our systems. Any temporary data on your device is subject to your device’s own security (e.g. lock screen, encryption).
8. Your Rights
Depending on your region, you may have rights such as access, correction, deletion, or portability of your data. Since we do not collect or store your personal data on our systems, there is no personal data held by us to access or delete. You can at any time:
- Clear calculation history from within the app.
- Uninstall the app to remove all app-related data from your device.
9. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top will be revised when changes are made. For significant changes, we may notify you via the app or the store listing. Continued use of the app after changes constitutes acceptance of the updated policy. We encourage you to review this page periodically.

*This Privacy Policy is intended to meet common disclosure expectations for Google Play Console and general best practices for a minimal-data utility app.*
