3. Information We Do Not Save
We do not save any user data on our servers or in any external databases. All calculations created using our App are stored locally on your device and remain under your complete control. We do not have access to, nor do we store:

4. Local Storage Only
Our App operates primarily on your device without requiring an internet connection for core functionality. All data created by the App, including calculations, history, and settings, are stored locally on your device. This means:
- You have complete control over your data
- No calculation data is transmitted to our servers
- No data is stored in the cloud or on external servers
- Your calculations remain private and accessible only to you
- We cannot access, view, or analyze your calculations or any other data
5. No Data Sharing
We do not share, sell, rent, or trade any user information with third parties. Since we do not collect any user data, there is no data to share. We are committed to maintaining your privacy and will not compromise your personal information under any circumstances.
6. Third-Party Services
Our App may contain links to third-party services such as the Google Play Store for updates or additional content. These third-party services have their own privacy policies and we encourage you to review them. We are not responsible for the privacy practices of these third-party services.
The App may periodically update currency conversion rates from publicly available sources, but this process does not involve transmitting any personal information.
7. Permissions
Our App may request certain permissions to function properly. These permissions are necessary for the App to provide its core functionality and are not used to collect any personal information:
- Storage: Used to save calculation history and preferences on your device
- Network Access: Used only for updating currency exchange rates (not required for core functionality)
- Home Screen Widget: Used to display calculator widget on your device's home screen
These permissions are used solely for the purpose of providing the App's functionality and not for collecting any personal information.
8. Data Security
Since we do not collect or store any user data on external servers, there is no risk of data breaches or unauthorized access to your information. All calculations and preferences created using our App remain on your device and are protected by your device's security measures.
9. Children's Privacy
Our App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have inadvertently collected personal information from children under 13, we will take immediate steps to delete such information.
