GrapheneOS es un sistema operativo móvil gratuito y de código abierto basado en Android, reforzado con seguridad, centrado en la privacidad para teléfonos inteligentes seleccionados. Se conocía como Android Hardening hasta marzo de 2019 y se centra en la privacidad y la seguridad. Es compatible con varios teléfonos inteligentes Google Pixel.

I didn’t test Graphene OS, but from what they write it seems a trade-free operating system for phones. “GrapheneOS improves the privacy and security of the OS from the bottom up. It has a hardened kernel, libc, malloc and compiler toolchain with many low-level improvements. These changes are designed to eliminate whole classes of serious vulnerabilities or provide meaningful barriers to exploitation. We avoid making changes without a clear rationale and we regularly work towards simplifying and replacing these low-level improvements.” (https://grapheneos.org/) to me they seem to completely get rid of google and provide an operating system that does not want to exploit its users for the sake of trade. The website does not have trackers and ads neither. Because of that I give them 5/5. Of course I could be wrong, so if you find any trades, let us all know here.
