It's an OS made by Murena

Or to give you a more serious answer, it's also called /e/os. It's a deGoogled Android distro you can get preinstalled on some phones, including the Fairphone 6.

Basically, it offers a way for less techy folks to switch to a Google free Android OS, as you don't have to unlock bootloader, flash ROM, etc. Does cost an extra 50 euros for the privilege though.
