Communication
Securing your digital assets requires the ability to communicate with others, in a private and secure way.
Software
Signal
Why this software?
Open-Source
Cross-Platform
Fully encrypted, protecting metadata (does not capture to whom you talk, and when - all the others capture these)
Advocates for user privacy
