What It Does
OneBuddy includes a truly private messaging feature using ECDH P-256 key exchange and AES-GCM 256-bit encryption. Messages are encrypted on your device before transmission and can only be decrypted by the intended recipient. Zero-knowledge architecture means not even the relay server can read your messages.
Why It's Better Than Standalone Extensions
No other Chrome extension combines encrypted messaging with productivity and privacy tools. You get private messaging alongside ad blocking, screen recording, and 10+ other tools — all in one extension. No separate app installation required.
