How Zero-Knowledge Notes Work
Under the Hood.
Most cloud apps trade your privacy for real-time sync. Foxcolab Notes proves that with modern cryptography and distributed CRDTs, you can have both: instantaneous collaboration and unbreakable privacy.
Instant In-Memory Markdown Evaluation
When you type in Foxcolab Notes, characters are written directly to local browser memory and evaluated in sub-milliseconds. Formatting, headings, and code blocks render instantly with zero network latency.
Client-Side Zero-Knowledge Encryption
Your master passphrase stretches locally on your physical device. Every document mutation is sealed into an authenticated binary envelope before any network packet is transmitted.
Seamless Conflict-Free Synchronization
Foxcolab edge servers act strictly as blind message relays. They receive encrypted binary envelopes, store ciphertext blobs, and stream them securely to your other authorized devices. Edits merge conflict-free even after extended offline sessions.
Local Bi-Directional Backlink Indexing
Because servers cannot read your notes, your knowledge graph is computed and indexed locally in device memory. [[Wiki-links]] and incoming mentions resolve in microseconds without leaking associative query telemetry.
