Every note protected by design.
A privacy-first notes app built around a simple promise: nobody reads your notes but you. Not us, not iCloud, not an advertiser. Here is what that means in practice.
End-to-end encryption
Every note — text or voice — is encrypted on-device with AES-256-GCM before it touches disk or iCloud. Keys are derived from your passphrase via PBKDF2 (100,000 iterations) and never leave the device.
Secure voice notes
Record encrypted voice notes up to 10 minutes. Playback at 0.5×–2.0×. Generate an on-device transcript. The audio is locked behind the same Face ID gate as your text.
Biometric & passcode lock
Face ID, Touch ID, or a 4–32 character passcode. Biometric unlock is gated by the Secure Enclave; we never see the print, the face, or the passcode.
Per-folder passwords
Group sensitive notes into a folder and give it its own password, distinct from the app passcode. Two-tier access for the things that need it.
Encrypted iCloud sync
Notes sync across iPhone and iPad through iCloud — but the payload is ciphertext. Apple cannot read your notes; neither can we.
12-word recovery seed
A BIP-39-style mnemonic generated once, stored only by you. Lose your passphrase, recover your vault. Lose the seed and us, no one can.
Portable & future-proof
Export your vault, re-encrypt it, migrate it. No lock-in, no proprietary container, no hidden cloud dependency. Your data is your data.
Considered, not cluttered.
Every screen is designed to keep you writing and your content hidden. The security is serious. The interface is quiet.
Voice notes, encrypted
Record up to 10-minute voice notes — same vault, same encryption, same Face ID lock.
Mixed media, one vault
Text notes, voice notes, and pinned folders side by side. Locked items stay private.
Live security score
A tailored audit of your vault — biometric lock, recovery seed, sync, auto-lock.
Playback at your pace
Re-listen at 0.5×–2.0× or generate a transcript. Audio never leaves the device unencrypted.
Quiet first launch
A single locked private note and a prompt to record. No tour, no tutorial.
PRO unlocks the rest
Unlimited folders, exports, secure cloud sync. All cryptography stays free.

Privacy is the default, not an upsell.
No analytics on your content. No developer keys. No server-side reset link. The engineering choices we made reduce the number of people who could ever read your notes to exactly one: you.
Zero-knowledge architecture
Keys are derived on-device from your password. They never leave the device. The publisher cannot decrypt your content.
No content analytics
The app does not scan your notes for advertising, ML training, search ranking, or anything else. Ever.
Minimal permissions
Face ID and iCloud only. No location, no microphone, no contacts, no notifications, no background fetch.
Audited cryptography
AES-256-GCM (FIPS-197) with keys derived via PBKDF2 (100k iterations). Named ciphers. Documented choices.
