Protecting app security and preventing fraud
Your calculation history, language preference, and cached data are stored locally on your device using standard iOS storage (UserDefaults and similar).
Currency exchange rates are fetched from a third-party API (e.g., Frankfurter) and cached locally. No personal data is sent to that API.
We employ industry-standard security measures to protect data on your device.
Data is encrypted during transmission when the app fetches exchange rates over HTTPS.
We promise:
We will not sell, trade, or transfer your personal information to third parties for marketing purposes.
We will only share information when required by law or to protect our legal rights.
Currency exchange rates are obtained from publicly available APIs. No user data is shared with these services.
Subscription and payment data are processed by Apple; please refer to Apple’s Privacy Policy for how Apple handles that information.
You have the right to:
Access, modify, or delete your locally stored data (e.g., clear calculator history within the app or by uninstalling)
Withdraw consent or restrict data processing
Request information about what data we hold
File complaints or inquiries with us
Our services are not directed to children under 13 years of age. We do not knowingly collect personal information from children. If we discover that we have collected information from a child, we will delete it immediately.
We may update this Privacy Policy from time to time. Significant changes will be notified to you through in-app notifications or on this page. Continued use of the app after changes indicates acceptance of the updated policy.
