[Q] [S] Most Secure Rom for Photon Q (like Blackphone) topic

Hey Everybody,

since i'm getting more and more concerned about my privacy, i've started looking for more than just an app to password-protect various apps. I was wondering if there is anything like a blackphone-rom or something security-oriented like that for my photon q? Ive googled and looked in the development-areas of xda but i wasnt able to find anything.

If not a rom, are there some security tipps for special apps or tweaks to secure my phone and the data on it, if i ever loose my phone?

Thanks in advance

V.
