Stealth Notes
Stealth Notes is the built-in encrypted notes app for Windows. It supports rich text, attachments, and folders, and syncs end-to-end encrypted with your other Stealth devices through Account Sync.
Opening Stealth Notes
Open from Settings → Tools → Stealth Notes. The window opens with the folder tree on the left, your note list in the middle, and the editor on the right.
Notes and Folders
Folders. Organize notes into nested folders. Drag and drop to reorder.
Rich text editor. Bold, italic, underline, headings, lists, checklists, links, code blocks, tables, and inline images.
Attachments. Attach any file to a note. Attachments are encrypted alongside the note body.
Search. Full-text search across every note. Filter by folder and date.
Pin notes. Pin important notes to the top of the list.
Export. Export single notes or whole folders as Markdown or HTML.
Encryption
Every note and attachment is encrypted on your device with AES-256-GCM before it touches disk. The encryption key is derived from your Stealth account password using Argon2id and never leaves your device.
Account Sync
If your Stealth account is linked to other devices, your notes sync end-to-end encrypted between them in real time. Edits made on Windows show up on your other devices within seconds of going online.
- Real-time sync across all linked devices
- The server only stores encrypted blobs
- Works offline, queued changes sync when you reconnect

Private by default. The server never sees your note content.
Cross-device. Notes follow you between Windows and Android once Account Sync is set up.
Built in. No extra app to install or manage.
