How do I change my profile picture or name?

Open your profile (the icon at the top right of the list overview). Tap your profile picture at the top to change it — you can take a photo, pick one from your photos or files, use one from your contacts, or remove it again. You change your name and email right below via „Edit“; you can also sign out from the same profile via „Log out“.

Your picture and name are what others see of you in a shared list — your own photo makes it clear at a glance who's doing what.
