TaskNote encrypted notes app showing lock icon and private notes

Zero-knowledge encryption, on by default

Most apps call themselves "secure" but store your notes in plain text on their servers. TaskNote encrypts every note on your device using AES-256-GCM before it leaves. The server stores only ciphertext it cannot read. Your key never travels.

  • AES-256-GCM encryption on every note
  • Key derived from your password, never transmitted
  • Zero-knowledge: even TaskNote cannot read your notes
  • Encrypted in transit and at rest

  • Safe to store passwords and credentials
  • Personal journals protected from prying eyes
  • Legal and medical notes stay private
  • No data sold, no analytics on note content

Questions about note encryption

What does end-to-end encrypted notes mean?

End-to-end encryption means your notes are encrypted on your device before being sent anywhere. The server only receives ciphertext - it cannot read your notes. Only your device, with your key, can decrypt them.

Can TaskNote read my notes?

No. TaskNote uses zero-knowledge encryption. Your encryption key is derived from your password and never leaves your device. The TaskNote servers store only encrypted data they cannot decrypt.

What encryption algorithm does TaskNote use?

TaskNote uses AES-256-GCM encryption - the same standard used by banks and government agencies. Keys are derived using PBKDF2 and never transmitted.

Is TaskNote free?

Yes. End-to-end encryption is included on the free plan forever. No credit card required. Notes, kanban board, and reminders are also free.

What happens if I forget my password?

TaskNote provides a recovery key when you set up encryption. Store it safely - if you lose your password and your recovery key, your encrypted notes cannot be recovered by anyone, including TaskNote.

Does encryption work on all devices?

Yes. Notes are encrypted on every device - iPhone, Android, Mac, Windows, or any browser. The same zero-knowledge encryption applies everywhere.
