GrapheneOS is a project focused on privacy security and privacy features.

In order to do that, hardware is a pretty important part of the equation.

Therefore, the project has specific security requirements that the hardware must meet in order to be considered as a potential target device to support.

Of course, these requirements are adjusted and updated as things improve; security is a moving target.

Google Pixel devices are currently the only devices meeting said requirements.

A non-exhaustive list of those requirements can be found here:

I also briefly wanted to touch on this:

Periegnis if security and de-googling our life is part of all of this,

GrapheneOS comes with no Google services by default, and people can use it if they want to avoid Google services, but "de-googling" isn't really a goal of the project in and of itself, rather than just providing a secure and private OS.

Periegnis

It surprises me when people complain about Google on a security level. I understand a privacy level, but pretending Google isn't a titan in software and hardware engineering is insane. Some of the most impressive (and usable) technology comes from them
