Privacy Bar

PRIVACY BAR: LOCAL ENCRYPTION & SECURITY SUITE Your data. Your device. Nobody else. Privacy Bar is a full encryption and privacy toolkit that runs entirely inside your browser — no servers, no accounts, no cloud sync. Encrypt messages, hide data in images, generate passwords, and sanitize links, all without a single byte ever leaving your machine. Built on one rule: if it's sensitive, it never touches a server. Everything happens locally. Nothing is stored unencrypted. Your Master Key is never saved anywhere — it lives in memory for five minutes, then a mandatory Security Auto-Wipe erases it. FREE FOREVER • Password Engine (No Vault) Password managers store your secrets in a database — which means there's a database to steal. Privacy Bar generates your passwords on the fly from your Master Key instead of storing them. No vault, no file to breach, no sync target for an attacker. • Hashili Check A short, human-readable phrase that confirms you typed your Master Key correctly — without ever displaying or transmitting the key itself. • Lock & Key System Trade "Locks" (public keys) with contacts for asymmetric encryption. Only the matching Master Key can open what's sent — no more emailing plaintext passwords and hoping for the best. • Digital Camo (Steganography) Embed encrypted data invisibly inside ordinary JPEG or PNG images. To anyone else, it's just a photo. PRIVACY BAR PRO • Post-Quantum Ready Uses NIST-standardized ML-KEM (FIPS 203) for key encapsulation, so today's encrypted data stays protected against tomorrow's quantum computers. • Pad Mode Generate a true one-time pad from a file's entropy — the only encryption method with a mathematical security proof, when used correctly (one pad, one message, never reused). A high-performance streaming engine handles multi-gigabyte files without choking. • Read-Once Messages that can be decrypted exactly one time. Once read, the keys are destroyed — nothing left behind for forensic recovery. • Hidden Message Slip an extra 100 bytes of hidden data into any output, for situations that call for plausible deniability. • Remote Sanitizer Right-click any link to open it in a sandboxed Reader Mode that strips scripts and tracking metadata before the page ever loads in your browser. BUILT FOR Journalists & Activists — Smuggle documents inside ordinary social photos with LSB embedding. Use Read-Once for tips that need to leave zero digital trail. Professionals — Send confidential contracts over standard email without your provider's servers ever seeing the plaintext. Researchers & Academics — Keep encrypted, site-specific notes in the sidebar. Your intellectual property never leaves your machine. WHY TRUST PRIVACY BAR • Zero-Knowledge — We can't see your keys or your data, because they never reach us. There's no "us" in the loop. • Permission-Light — Built on Chrome's activeTab model. Privacy Bar only sees a page's data when you click the extension — not before, not in the background. • Source Available — Read the actual logic yourself, in your browser or on GitHub. No blind trust required. • PolyCrypt — A manual pencil-and-paper cipher included for the truly air-gapped: works even if every computer you own is gone. TECHNICAL SPECS Algorithms: ECC (Curve25519 / Ed25519), NaCl, ML-KEM (post-quantum), PolyCrypt Architecture: 100% client-side. Zero external API calls, zero telemetry.
