So currently, it's a couple days after police and intelligence agencies worldwide raided the owners of ANOM-using phones that were allegedly private and built to exclude common hardware/software that's used for tracking. I'm not saying the governments of the world were wrong to bring those people down. But do you really expect anyone to buy a phone - with any combination of hardware and software - and retain any expectation of privacy whatsoever? Am I paranoid to think that this sounds like a continuation of the ANOM project... selling a supposedly secure, home brew and private device to the gullible who desperately want a secure channel?
Here's a secure channel: Dump your phone. There's no personal security with a device like that if you live in a state that might use your affiliations against you.
