Overview
Calcy ("the app") respects your privacy. This policy explains how the app handles information.
We Do Not Collect Personal Data
Calcy does not collect, store, or share any personal information. There are no accounts, no analytics SDKs, no advertising, and no tracking. Your calculations, history, and memory are stored only on your device.
Network Use (Currency Rates)
The optional currency converter fetches up-to-date exchange rates from a third-party service (open.er-api.com). These requests contain no personal information — only a standard request for the latest published rates. Fetched rates are cached locally so the converter also works offline. If you never open the currency converter, the app makes no network requests.
Third-Party Services
Aside from the exchange-rate provider named above, the app integrates no third-party analytics, advertising, or tracking services.
Data Security
Because the app collects no personal data, your information stays on your own device, protected by iOS security.
Children's Privacy
The app is suitable for all ages and does not collect information from anyone, including children under 13.
