I would only send pics of my kid over signal
One thing that would worry me in your shoes is what happens to those pics after they hit the other person’s dev. Ok there’s a secure way to send them over the network. Now they’re on somebody’s phone running a million skeevy apps they gave photo access permission.










That’s my guess too. I think a lot of non-techie ppl have been burned by “freemium” apps that are steaming piles of shitware. It’s kind of a hard distinction to explain, between “free” as in reputable OSS, and “free” as in spyware and thinly disgused malware. So they go wtih brands with name recognition. Like, you know, Facebook. Or Google.
