In Threema, you can set a profile picture that represents you in your chat partners’ contact lists. You can fully control who is allowed to see your profile picture. Set a profile picture as follows:
For privacy reasons, profile pictures are not stored on a server, they are transmitted between users upon message exchange and are end-to-end encrypted.
The next time you send someone a message, your profile picture will be transmitted automatically (provided your settings allow it). Alternatively, you can transmit your profile picture manually to a contact by tapping “Send profile picture now” in the contact’s detail view.
If a contact has disabled profile pictures, your profile picture will not be displayed in their contact list and chat overview.
