I do not have the app installed on my device any longer, can I still delete my account? 
Yes, just log into your account on our website instead, go to Profile and then press on "Delete account", or you can follow this link to get there directly. 
Note! In case you are still logged into the account, please delete the app from your phone. After that you will not be able to log in again.
