Why Most Messaging Apps Aren't Secure

Server Storage Vulnerability

Any messaging app that stores messages on servers is vulnerable to breaches, hacks, and unauthorized access. Your private conversations are only as secure as their servers.

Closed Source Risk

Closed-source apps require blind trust - without code transparency, security claims cannot be verified. You can't truly know what happens to your messages.
