Notes under seal

A notes app for iPhone, iPad and Mac that encrypts everything on your device — before it is written to disk or sent to iCloud. Only you can read it.

Coming soon to the App Store

iOS and iPadOS 17 or later · macOS 14 or later

What it does

Encrypted on your device
Every note and attachment is sealed with AES-256-GCM. The key lives in your iCloud Keychain, and you can save a recovery key.
Your own iCloud, no other server
Notes sync through your personal iCloud and stay on each device, so they are there offline. SealNote has no server of its own.
Search inside pictures and PDFs
Text in photos and scanned pages is recognised on the device. Found words are highlighted in the note and in the document.
Notebooks you can share
Share a notebook with other people who use Apple devices, for reading or for editing. It gets a key of its own; your other notes stay out of reach.
Markdown, checklists, attachments
Write with live formatting, tick boxes with a tap, keep photos and files in the note, take a photo or a video straight into it.
Bring your notes along
Import from UpNote and Evernote with notebooks, dates, tags and attachments.

Nothing.

No ads, no analytics, no tracking, no code from anyone else that sends data anywhere. The developer cannot read your notes.

AES-256-GCM

The app speaks English, French, German, Spanish, Italian, Portuguese and Russian.
