Once a year we deactivate inactive users and eventually delete their user information. We do this because we do not want to store your data unnecessarily, and because we want the number of users in Sona to reflect the actual pool of participants that researchers can recruit from. If you wish to keep your account and be able to participate in studies at COBE Lab, please make sure to log into your account before 1 November 2018. 

You can delete your account at any time under "My Profile" in Sona.
