That got me interested in it for the privacy claims, but unfortunately it only supports Pixel phones. The reasons are technical and fair. It's just unfortunate that Pixel isn't sold or supported in many countries in the world. I live in Brazil and even in Mercado Libre where it's supposed to support the entire Mercosul market, I can't find a single Pixel 8 for purchase. It's sad we're excluded from accessing this amazing project.

I think that you could get similar privacy capability with LineageOS if you do not install Google Play (via MindTheGapps).
This will reduce functionality of the device. You will not get Graphene's fine-grained permission control, and you will also not have Google Play Services (so many apps will not run).
