I would strongly recommend moving as far away from Signal as possible. There’s heavy corruption by the U.S. in that area. It’s not fully encrypted, not to mention it can still be monitored on when and if someone’s sending a message, just not all the content.

Here’s a good essay by Dessalines on the matter, they’ve been dealing with cybersecurity for a while, though I don’t know anything about the other recommendations on the photo: https://github.com/dessalines/essays/blob/main/why_not_signal.md
