Hi there, tbh I forgot what my comment was before I deleted it. You probably just answered yourself in this post :)
But yeah for security I don't prefer Telegram or any Android app and I use Telegram the most on Android because I like the way it is. No Secret Chat really, are you sure about that lol
Hmmm... OpenFX 1.5 seems to be open source on Github though. Why are you talking about cracking then?
If you need to be more specific you can just DM me.
