Is Open Source Software More Secure?
Quick Answer
For privacy and security tools, yes. Open source allows independent security researchers to verify that the software does what it claims — no hidden backdoors or secret data collection.
Detailed Explanation
Open source doesn't automatically mean more secure, but for privacy tools it's essential. Here's why: (1) Verifiability — anyone can read the code and confirm the encryption works as claimed. (2) No backdoors — hidden surveillance code would be spotted by the community. (3) Community auditing — thousands of eyes reviewing code find bugs faster. (4) Trust — you don't have to trust the company's privacy claims when you can verify the code. Telegram's server is closed source — you can't verify what happens to non-secret-chat messages. WhatsApp is closed source — you can't verify metadata collection. zkChat is fully open source under AGPL-3.0 — every line of both frontend and backend code is on GitHub for anyone to audit.

What Is the Most Private Messaging App?
The most private messaging app is one that requires no identity, collects no metadata, stores no messages, and is fully open source — zkChat meets all of these criteria.
Is End-to-End Encryption Really Secure?
Yes. Properly implemented E2EE using algorithms like AES-256-GCM is mathematically secure — breaking it would take longer than the age of the universe with current technology.
What Is Zero-Knowledge Encryption?
Zero-knowledge encryption means the service provider is technically unable to access your data — not just promising not to, but cryptographically prevented from doing so.
