You can update your details in the app by tapping the profile icon bottom right and "Personal details". You can tap on your initials/profile picture to upload/edit your profile picture. Additionally, you can tap on the pencil to edit your residential address and email.
To change your name, you should contact customer service by phone or email. Unfortunately, it is not possible to change your phone number.
When editing your email address, make sure you enter the correct one. Important information goes out by mail, and if you report an issue to us (etc regarding a refund), we will contact you on the mail you have registered. If the mail is incorrect, we will be unable to assist you. Once your email is changed, you will be signed out of the app automatically and must log in again.
