XChange is a currency conversion app. This page explains exactly what data it handles.
None. XChange has no account system, no sign-in, and no backend server of our own. The currencies you choose to track are stored only in the app's local storage on your device.
To show current exchange rates, XChange fetches publicly available rate data from third-party providers (frankfurter.dev and the fawazahmed0 currency-api). These requests only ever contain currency codes (e.g. "USD", "EUR") — no personal information, device identifiers, or account data is sent. These providers' own privacy practices apply to that request traffic; DFB Software does not control or receive any data from them beyond the exchange rate figures themselves.
XChange contains no third-party advertising SDKs, analytics SDKs, or tracking of any kind. We don't use the App Tracking Transparency framework because we don't track you.
XChange offers an optional one-time premium unlock and optional tips, processed entirely by Apple through StoreKit. Payment details are handled by Apple under Apple's own privacy policy — DFB Software never sees or stores your payment information.
Questions about this policy or your data can be sent to support@dfbsoftware.dk.
