Privacy and security remains an integral part of our approach - the user can choose to remain anonymous and their privacy will be protected as they go about their daily life. Should a user develop symptoms they will be asked for permission to donate the log of contact data. If app users choose to submit their data to the National Health Service, either proactively or when requesting a test, it will be held on a NHS database held to highest security standards. Users will at any time be able to remove the app from their phones.
