I just found out this ROM a few months ago, they don’t advertise it too much, most of the talk happens on their Telegram channels.

They provide some features from Graphene that could interest DeGooglers. Like sandboxed Play Services, even tho, very important to note, they don’t advertise it as a “degoogled” or “privacy-focused” ROM, but they provide these features (some imported from Graphene):

• Storage, contacts and files scopes: trick apps so they think they have access to all files or contacts, but you chose what files and contacts apps can see.
• Option to disable sensors by default: something I learned just a few weeks ago, sensors are a allowed permission by default for all Android apps, they block it and notify you if any app try to access the sensors.
• Ask for network access before installing any app, instead of granting it automatically.
• Graphene servers for assisted GPS instead of Google servers.
• Built in integrity fix and tricky store: you don’t need root to get integrity fix (one level), but you need a keybox to get other levels. I personally achieve two levels (BASIC and DEVICE) with any random public keybox.
• Spoofing features: spoof device model for games and hide apps list.
• PowerHub with many interface customization.

There are few devices officially supported (14 I guess, mostly Xiaomi), but you could build it for your device if you know how to do it and possibly bring more attention to it. All their sources are on GitHub.
