Signal is an end-to-end encrypted messaging app. Privacy isn’t an optional mode, it’s just the way that Signal works. Every message, every call, every time.
Secure backups will let you save an archive of your Signal messages remotely in privacy-preserving form, refreshed every day.

Now available in the latest Android beta release, rolling out to iOS and Desktop in the near future.

One piece of misinfo we need to address is the claim that there are ‘vulnerabilities’ in Signal. This isn’t accurate. Reporting on a Pentagon advisory memo appears to be at the heart of the misunderstanding: npr.org/2025/03/25/n.... 2/
