Signal

This software revolutionizes messaging with its unexpected focus on privacy and a full suite of expected features. The platform boasts state-of-the-art end-to-end encryption powered by the open-source Protocol, ensuring your conversations remain secure. Unlike other messaging apps, it doesn't read your messages or listen to your calls, and neither can anyone else. Privacy is not an optional mode on; it's the fundamental way the platform operates. Every message, every call, every time – your communication remains confidential.
