About

DivestOS is a full-time passion project (not a company) maintained solely by Tavi since 2014. It has many goals, but primarily: prolonging the life-span of discontinued devices, enhancing user privacy, and providing a modest increase of security where/when possible. The devices DivestOS supports are not fully free (as-in-freedom) and there are many security issues we cannot solve such as insecure proprietary blobs, insecure firmware, insecure bootloaders, and insecure ancient kernels. We are also fully aware of our "off-the-rails" approach, however mostly attribute it to the sheer effectiveness provided by "80%" solutions instead of mulling around and not doing anything. We genuinely believe that what DivestOS offers is something unlike any other project, especially with regards to the project scope and our persistence. We hope you find some benefit in our fruits, and remind you to have fun!

Also a huge thanks to Daniel Micay; DivestOS utilizes many hardening patches from GrapheneOS and the AndroidHardening CM-12.1/13.0 archive. Time flies.
