Secure messaging is about much more than end-to-end encryption. Metadata collection, open-source transparency, independent audits, default encryption, account requirements, backups, and jurisdiction all influence how private a messaging platform actually is. This comparison examines the major privacy-focused messaging apps and discusses the trade-offs each one makes instead of trying to crown a single “best” option.
Not sure what you mean, but you can set it to immediately lock when the device is locked. So all it takes is for the screen to sleep or manually lock the phone.
I set mine to immediately lock but there’s options for 5, 10, 30 seconds, etc.
It would be an auto-self destruct if you take more than X amount of days between successfully entering a code. So, like, if you died, it’d wipe itself after a certain number of days automatically.
Ah, not to my knowledge. But for me, considering everything is locally encrypted, thats sufficient. I’d imagine that the prospect of accidentally wiping the contents with an incorrect passcode would delay any attempts to crack it.
