Whosetrack stores only the username for users that use Whosetrack without Spotify. For users with Spotify, Whosetrack saves the Spotify username, ID and the profile picture url. These properties are saved to allow users to connect to eachother in the app. Whosetrack requires CAMERA access. This access is required to allow for scanning QR codes which make it easier for users to join eachothers competitions. Camera images are not saved anywhere by the app. In case a user wants his or her data deleted, they can send an email to info@whosetrack.nl after which a response can be expected within a week.
