End-to-End Encrypted Messaging Chrome Extension

What It Does

OneBuddy includes a truly private messaging feature built directly into the Chrome side panel, using ECDH P-256 key exchange and AES-GCM 256-bit encryption — the same cryptographic standards used by governments and financial institutions. Messages are encrypted on your device before transmission and can only be decrypted by the intended recipient's browser. Zero-knowledge architecture means not even OneBuddy's relay server can read your messages — it only handles encrypted data it has no ability to decrypt. No separate messaging app installation is required; both parties simply need the OneBuddy extension. The system collects no message logs, no metadata, and performs no user tracking.

Why It's Better Than Standalone Extensions

No other Chrome extension combines end-to-end encrypted messaging with productivity and privacy tools. Signal and Telegram require separate desktop apps; WhatsApp Web requires a phone connection. OneBuddy gives you browser-native encrypted messaging with ECDH P-256 and AES-GCM 256-bit encryption alongside ad blocking, screen recording, privacy blur, and 10+ other tools — all in one extension. By consolidating encrypted chat with your other daily tools, you reduce your software footprint and keep everything accessible in the Chrome side panel. The zero-knowledge architecture ensures complete privacy with no message logs or metadata collection.

Feature Breakdown

Frequently Asked Questions

How is the encryption implemented?
OneBuddy uses ECDH P-256 for key exchange and AES-GCM 256-bit for message encryption — industry-standard cryptographic algorithms.
Can the server read my messages?
No. Zero-knowledge architecture means messages are encrypted on your device before transmission. The relay server only handles encrypted data it cannot decrypt.
Do both parties need OneBuddy?
Yes. Both the sender and recipient need OneBuddy installed for end-to-end encrypted messaging.
Are messages stored?
Messages are handled with privacy-first design. The system is built around zero-knowledge principles with no message logs or metadata collection.
Is the encrypted messaging extension free in 2026?
Yes. OneBuddy's encrypted messaging is completely free in 2026 with full ECDH P-256 + AES-GCM 256-bit encryption, zero-knowledge architecture, and no premium tiers.
How does OneBuddy's encrypted messaging compare to Signal?
Signal requires a separate desktop app and phone number. OneBuddy provides browser-native encrypted messaging with industry-standard cryptography directly in your Chrome side panel — no separate app or phone number needed. Plus you get 13 other tools.
What encryption standard does OneBuddy use for messaging?
OneBuddy uses ECDH P-256 for key exchange and AES-GCM with 256-bit keys for message encryption. These are industry-standard cryptographic algorithms used by governments, banks, and security-focused organizations worldwide.
