“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.”
Interesting. I use signal with my family, coworkers, and some friends. Never once done drugs, and only a couple people I know that use it did drugs in the past, and didn’t use signal then.
