Zero-Knowledge Notes.

Your ideas stay yours. E2E AES-GCM encryption means your master key never leaves your device. Even we can't read your notes or attachments.

Military-Grade Encryption

DueLoom derives your master encryption key from your password using PBKDF2. Every note and file attachment is encrypted locally on your device before it ever touches our servers.

  • AES-GCM Encryption algorithm
  • Encrypted attachments stored on Cloudflare R2

Offline First

No internet? No problem. Read and edit your notes offline. They'll securely sync the moment you reconnect.

Always Available

Under the hood, DueLoom uses a powerful local database (Dexie/RxDB) to store your encrypted notes on your device.

Whether you're studying in a dead zone at the library or commuting on a subway, your notes are always instantly accessible and blazing fast.
