πŸ”’ Private by design

Your notebook,
encrypted on your device.

CalixNote keeps your notes, photos and files encrypted on your iPhone β€” with no account, no cloud and no tracking. Everything stays with you.

CalixNote app
Everything in one vault

Three private spaces, one secure app

Notes, images and files β€” each encrypted before it ever touches storage.

Encrypted notes

Folders, tags, colors, pinning, search, Markdown preview, templates and reminders β€” all encrypted with ChaCha20-Poly1305.

Photo vault

Keep images encrypted in albums β€” and hide a secret text message inside any picture with built-in steganography.

Files & 3D models

Store any document encrypted, and preview .glb 3D models in a built-in viewer that runs fully offline.

PIN & Face ID lock

Lock the app with a salted-hash PIN and unlock with Face ID or Touch ID. Repeated wrong tries trigger an escalating lockout.

Dictation & OCR

Dictate notes by voice (prefers on-device), scan text from photos, and have notes read aloud β€” processed on your device.

10 languages

A fully localized interface with automatic dark mode and an iPad-ready layout. Pick your language in a tap.

Security

Locked down by design

Your content is encrypted before it’s written to disk, and the keys are generated on-device and stored in the iOS Keychain β€” they never leave your phone.

  • AES-256-GCM & ChaCha20-Poly1305 (Apple CryptoKit)
  • Keys held in the iOS Keychain β€” never uploaded
  • Password-protected .clx backups you control
  • No servers, no analytics, no third-party SDKs
