FadCam looks exactly like what I’m looking for, but looking at the author’s GitHub, it’s a part of fadsec-lab suite, described like:

FadSec-Lab is a suite of Shariah Compliant, ad-free, privacy-focused open-source apps dedicated to enhancing user security and privacy.

What exactly is a Shariah compliant app? 99% of the descriptions look great, but I’m unable to interpret this statement. Has anyone used this app?
