“When you use Signal, your data is stored in encrypted form on your devices. The only information that is stored on the Signal servers for each account is the phone number you registered with, the date and time you joined the service, and the date you last logged on.”
Not only that, it makes people less likely to move to something new. I had almost everyone moved to signal. Now there’s one left, because it doesn’t work for SMS. Great choice they made. I haven’t even been able to convince one of my contacts to install simpled, and I doubt I’ll ever be able to. I had one shot, and wasted it on signal. I’m kind of salty.
