Yeah, I sometimes completely ignore questions people ask as answering could either bring more or simply cause me to be so cryptic the answers would be unsatisfactory to those who ask them - Having said that, some read between the lines, as I believe you have in some case, and that's ok, I don't mind; most aren't as savvy as you though.
Signal, I'm not sure if I can get that but I use Threema (a paid app) and it's pretty good for comms requiring a more secure platform. How secure is any of it though I guess, not very I suppose.
