Get started in 20 seconds
No complicated setup. No key management. Just create an account or use local mode and start writing — encryption happens automatically.
Trusted foundations
Built with industry-standard cryptography
Every layer of PrivyPad is designed to keep your notes private and secure.
Encrypted by default
Your notes are scrambled before they leave your device. Not even we can read them.
Password-protected keys
Your password creates a unique key that unlocks your notes. We never store or see it.
Nothing leaves your browser
All encryption happens right inside your browser — no data is sent unprotected.
Works offline
Use PrivyPad without an account. Your notes stay on your device, no server involved.
We can't see your data
Our servers only store encrypted blobs. Without your password, they're meaningless.
End-to-end encrypted
From the moment you type to the moment it's saved, your notes are always protected.
Encrypted collaboration
Share notes with your team. Each collaborator gets a wrapped copy of the note key — edits sync live, fully encrypted.
Two-factor authentication
Protect your account with TOTP-based MFA. Even if your password is compromised, your notes stay safe.
Self-destructing notes
Share encrypted notes that auto-delete after being read or after a set expiry. The key never touches the server.
Features
Engineered for absolute privacy
Every design decision serves one purpose — keeping your data yours.
01
AES-256-GCM Encryption
Every note is encrypted with AES-256-GCM entirely in your browser. The plaintext never touches our servers — only encrypted blobs are stored.
02
Argon2id Key Derivation
Your password is transformed into an encryption key using Argon2id, the winner of the Password Hashing Competition. Resistant to GPU and ASIC attacks.
03
Browser-Only Mode
No account required. Store your encryption key and notes locally in IndexedDB. Nothing ever leaves your device — total offline privacy.
04
Rich Text Editor
A Notion-style editing experience with slash commands, markdown shortcuts, task lists, code blocks, and more. Privacy doesn't mean compromising on features.
05
AI Integration
Claude, GPT, and Grok at your fingertips. You explicitly control when your decrypted content is sent to AI — full control stays with you.
06
Zero-Knowledge Architecture
Two separate salts for authentication and encryption. Even with complete database access, your notes remain mathematically unreadable.
07
Encrypted Collaboration
Share notes with your team without sacrificing privacy. Each shared note gets its own AES-256-GCM key, wrapped with each collaborator's personal key. Edits sync live — all end-to-end encrypted.
08
Secured Notes
Create encrypted, self-destructing notes with shareable links. The decryption key lives in the URL fragment — never sent to the server. Set expiry times and burn-after-read for maximum security.
Our philosophy
We don't just promise privacy — we make it mathematically impossible for anyone, including us, to access your data. Your encryption key exists only in your browser's memory. We never see it.
Client-side only. Key never stored. You control AI access.
