The WIMS App for iPhone uses no user sensitive data.
All data is stored on the user's device in an SQLite database, and is private to the application folder. No information is sent anywhere, unless the user decides to send it via the built-in iPhone "Share" feature. Typically this would be as a text export in CSV or tab-delimited format.
No system-derived data (eg, username, email address, device name etc.) is accessed by this App.
