Secured at the Source.
Foxcolab Notes operates on zero-knowledge encryption protocols. Draft documents, structure meeting notes, and build checklists. Everything is sealed locally inside browser memory before syncing.

Zero-Trust Architecture
Every document action is bound locally to secure client mechanisms.
Zero-Knowledge Architecture
Decryption keys are generated from your credentials in browser cache and never dispatched to remote database repositories. No administrator holds the power to inspect your secure workspaces.
IndexedDB Sync Cache
Your encrypted document state caches directly on local database structures inside the browser, enabling instantaneous startup operations.
CRDT Real-Time Merging
Co-draft simultaneously using Conflict-Free Replicated Data Types (Yjs). Deltas resolve locally before encrypting.
Rich Modular TipTap Engine
Construct complex structured wikis, checklists, responsive tables, and markdown containers in a responsive, fast client editor wrapper.
Derive Keys Locally.
Type any mock master password inside the controller input. Our client algorithms immediately run it through high-iteration key derivation functions (PBKDF2) to output a cryptographically strong 256-bit Master Identity Key.
Notice the shifting byte pattern below. As you alter the credentials, each individual derived byte hash calculates a unique color hue. The remote database nodes only ever see the derived public identity keys, keeping your raw passwords secure on your computer.
Interactive E2EE Sandbox
Select presets or type directly inside the mock markdown panel. Use the toggles on the right to switch between what is visible to you vs. what reaches our database nodes.

}No Cloud inspection. Instantaneous Load.
Standard note apps serialize, parse, index, and analyze document contents for telemetry and AI vector embeddings. This network pipeline slows down editing speeds and exposes passwords or meeting briefs.
Because Foxcolab Notes processes encryption strictly in client-side space, network payload streams are incredibly lightweight. We simply route binary deltas straight to databases, improving responsiveness while guaranteeing privacy.
Real-Time Collaboration. Fully Encrypted.
Co-draft specifications, strategy plans, and personal trackers without exposing intermediate edits. Foxcolab Notes uses Conflict-Free Replicated Data Types (CRDTs via Yjs) to compile and resolve concurrent keystrokes client-side.
As colleagues type, changes are compiled as cryptographic delta updates and broadcasted over secure websockets. Intermediate relays only pass encrypted bytes, keeping collaboration completely private.

Click through the steps of the local encryption process to see how document keys and envelopes are calculated browser-side.
Your browser computes a 32-byte symmetric Master Identity Key (MIK) by running password credentials through key derivation processes, completely offline on your device.

"With Foxcolab Notes, we finally found a tool that meets our strict internal security compliance without sacrificing the real-time collaboration that our product teams need. The client-side CRDT merges are incredibly fast."
Sarah Jenkins
Chief Information Security Officer
"Zero-knowledge is the only way forward for notes. Knowing that my thoughts, business ideas, and system schemas are encrypted on my machine before hitting the server gives me complete peace of mind. Truly excellent work."
David Chen
Principal Security Architect
"The offline-first architecture is a game changer. We can draft notes in meetings with zero network delays, and once we reconnect, Yjs resolves all concurrent changes seamlessly. The design feels incredibly premium."
