This application is a local-first calculator tool. Core calculation features work fully offline. Network connection is only required for public real-time exchange rate lookup. This App contains no advertisements, no user analytics, no third-party SDKs and no background data uploading. Registration or login is not required. By using this App, you agree to this Privacy Policy. If you do not agree, please uninstall and discontinue use immediately.
All user-generated data is stored locally on your device only and will never be uploaded, synchronized or transmitted externally.
Locally stored data includes calculation history, theme and dark-mode preferences, keypad sound, vibration settings, configuration preferences, and local premium unlock status.
You may clear calculation history manually within the App. Uninstalling the App will permanently erase all local data via iOS system.
This App collects zero personal data. We never collect, access or upload personal identifiers, photos, camera, microphone, contacts, location information, device identifiers or advertising identifiers (IDFA).
There is no background reporting, usage logging, user tracking or commercial advertising.
Core calculator functions are fully offline. Network requests are only initiated when you actively use the exchange-rate feature to fetch publicly available exchange data. These network requests retrieve only public information and will not carry, collect or upload any personal or device-related data.
The only network activities are user-initiated exchange-rate requests and official Apple in-app purchase verification handled by Apple. No other background transmission or data collection occurs.
All payment processing and order validation are handled exclusively by Apple App Store.
We cannot access your Apple ID, credit-card information or billing records. Premium unlock status is stored locally on your device only and is not synced to any cloud server.
This is a general-purpose utility application suitable for all-age users. No data is collected from any user, including minors.
All local data is protected by iOS sandbox isolation. No data is stored on external servers, so there is no risk of data leakage.
We may revise this Privacy Policy with App updates. Continued use of the application indicates acceptance of the latest policy terms.
