PRIVACY ARCHITECTURE
Privacy is not an optional feature.
Privyn is being built around a small set of security principles that influence the entire product architecture.
01
Client-side encryption
Message content is encrypted before transmission and decrypted locally.
02
Device-based identity
Privyn devices maintain independent cryptographic identities.
03
MLS secure groups
Privyn's current encrypted messaging architecture uses Messaging Layer Security for secure conversations.
04
Minimal server knowledge
Privyn infrastructure routes and stores encrypted communication data rather than message plaintext.
05
No advertising model
Privyn is not being designed around advertising or selling user data.
◇
“Private communication should not require surrendering the conversation itself.”
