## What is CalixNote?

CalixNote is a private notebook that keeps everything encrypted on your device. There is no account, no cloud and no tracking — your notes, photos and files never leave your iPhone unless you choose to export them.

PRIVATE BY DESIGN
• Every note, image and file is encrypted before it is written to storage.
• Encryption keys are generated on-device and stored in the iOS Keychain — they never leave the phone.
• No accounts, no analytics, no third-party SDKs and no cloud — your content is yours alone.

LOCK IT DOWN
• Protect the app with a 6-digit PIN (stored only as a salted hash) and unlock with Face ID or Touch ID.
• Repeated wrong PIN entries trigger an escalating lockout.

THREE SPACES, ONE VAULT
• Notes — folders, tags, colors, pinning, search, Markdown preview, templates and reminders.
• Images — store photos encrypted, view panoramas, and hide a secret text message inside any picture (steganography).
• Files — keep documents encrypted and preview 3D .glb models in a built-in viewer that runs offline.

WRITE FASTER
• Dictation in 10 languages — prefers on-device recognition, so it stays private and works offline whenever your language supports it.
• Scan text from photos with on-device OCR.
• Read notes aloud with automatic language detection.

ENCRYPTED BACKUP
• Export a password-protected .clx backup and restore it on another device. The backup is protected with PBKDF2 + AES-256-GCM and never contains your private key.

DESIGNED FOR YOU
• 10 interface languages, automatic dark mode, and an iPad-ready layout.

A note on encryption: CalixNote protects your data at rest using Apple CryptoKit (ChaCha20-Poly1305 and AES-256-GCM) together with the iOS Keychain and Data Protection. Encryption protects data stored on the device and is not a substitute for your device passcode.


## Version history (last 4 releases)

### 1.3 — 2026-08-10

• Fixed a flickering issue in the Notes tab's folder list on some iPhones.
• The note editor and reader now use the full screen for writing — no more wasted blank space at the bottom.
• Streamlined the editor's toolbar into a single row, giving more room to your notes.

### 1.2 — 2026-07-14

• Recently Deleted: notes you remove now go to a Trash you can restore from — kept for 30 days, then cleared. Empty it anytime.
• Auto-save: your writing is saved automatically every 15 seconds, so nothing is lost.
• A warmer writing space: the editor now looks like real notebook paper, with clearly labelled Title and Content cards.
• Rich text editing: bold, italic, underline, font size, indent, text color, bullet lists, and emoji — in one scrollable toolbar. New notes get the formatting bar too, starting at your preferred font size.
• Fresh new look: colorful hero banners, note cards with depth, and smooth animations across Notes, Images, and Files.
• Tap a note to read it distraction-free; edit only when you choose to.
• Search built right into the top of every tab, with live results.
• Folders, reimagined: every note lives in a folder, new notes get a tidy dated folder you can rename, and backups restore into their own folder.
• Stronger privacy: "Delete All Data" now permanently and irrecoverably erases everything, including the Trash and encryption keys.
• Fixes: Chinese text-to-speech reads correctly; dark-mode text color no longer disappears; Voice-to-Text asks for permission up front.

### 1.1 — 2026-07-06

Version 1.1 brings several new features:
• Voice recording & voice-to-text: A new Recordings tab lets you capture audio in-app, encrypted on your device. Long-press a recording to turn it into text — the new note is filed into a Voice Notes folder automatically. Available in 10 languages.
• Adjustable note font size for more comfortable reading and writing.
• Hide files inside images: Beyond text, you can now hide any file behind an image, protected by a passcode.
• Any passcode length when hiding content in images — no longer fixed at 13 digits.
• Duress PIN: If you're forced to open the app, enter a decoy PIN to reveal an empty vault and keep your real data safe.
• Search by the text inside your images (OCR).
Plus stability and performance improvements.
