Security Best Practices for Private Communication
Learn about the security measures and best practices for safe private communication.
When it comes to private communication, security isn't just about encryption—it's about the entire system design. At stash.chat, we've implemented multiple layers of security to protect your communications.
**End-to-End Encryption**: For 1:1 conversations, we use end-to-end encryption with secure key exchange. This means only you and your recipient can read the messages.
**Automatic Purging**: Messages are automatically deleted from our servers after viewing or expiration. We don't keep copies or backups of your conversations.
**Minimal Logging**: We only log what's necessary for abuse prevention and service operation. We don't track your behavior or build profiles.
**Secure Key Exchange**: Keys are exchanged through secure channels, and we use QR codes for easy, secure sharing.
**No Server-Side Storage**: Your plaintext messages never touch our servers in an unencrypted state.
But security is a shared responsibility. Here are some best practices for using stash.chat safely:
**Verify Recipients**: Always verify you're sending messages to the right person.
**Use Strong Passwords**: For rooms with passwords, use strong, unique passwords.
**Be Mindful of Screenshots**: While we can't prevent screenshots on user devices, be aware that recipients could potentially capture your messages.
**Check Expiration Times**: Make sure your expiration times are appropriate for your content.
**Report Abuse**: If you encounter inappropriate content or behavior, report it immediately.
Remember, no system is 100% secure, but we've designed stash.chat to minimize risks and protect your privacy as much as possible.
