Automatically Display Avatars for Your Users
Prefinery automatically populates user profiles with their publicly available avatar by looking up their email address in Gravatar, a third-party site which allows people to create, upload, and manage a globally recognized avatar from a single place.
When you are viewing a user's profile page in your Prefinery account, and if the Fetch User Avatars feature is enabled for your project, Prefinery will send a user's email address to Gravatar in order to look up their avatar and show it on their profile page.
If you don't want us to share end user information with a third party such as Gravatar, you can disable the Fetch User Avatars feature from your project dashboard from the Settings > General page.
