guys i want to recomment this Operating System because is secure and have privacy in mind. it does not have any binary/propriatary code.

I don’t see anything which makes PureOS particularly secure. That it doesn’t have proprietary code is not a good sign, see: Linux Overview - Privacy Guides . It is based on Debian testing (PureOS - Wikipedia). Debian says about this:

Compared to stable and unstable, next-stable testing has the worst security update speed. Don’t prefer testing if security is a concern.
