To conceal is to protect.
Private note-taking. AES-256-GCM secured.
[ your words. your key. your machine. ]
Leynir Notes is a Windows desktop note-taking app built for those who believe privacy isn't a feature - it's the foundation. Everything you write is sealed inside a single encrypted .vnote file on your own machine.
No accounts. No sync servers. No company with access to your thoughts. The key lives only in your memory. The data lives only on your disk.
Every byte of your vault passes through AES-256-GCM - the same standard used by governments and banks worldwide. Your master password never leaves your device; it's stretched through PBKDF2 with 600,000 iterations before it ever touches your data.
Unlock with your fingerprint or face via Windows Hello biometrics - convenience without compromise. The vault key is wiped from memory on lock or close. Only a SHA-256 verifier hash ever touches disk.
Split-pane live preview, editor-only, or preview-only modes. Full Markdown support - headings, tables, task checkboxes, code blocks, images, links, and more. Click checkboxes right in the preview.
Built-in highlighting for JS/TS, Python, HTML, CSS, JSON, SQL, Bash, Rust, Go, C#, and Java - all inside your encrypted vault, no external tools needed.
Nested folders with custom colours, expand/collapse, drag-and-drop manual ordering, A–Z sorting, and live note counts per folder.
A built-in 2×2 priority matrix - Do, Schedule, Delegate, Eliminate. Manage tasks per quadrant, mark them done, or archive them. Matrix blocks can also be embedded inline in any note.
Individual notes can have their own password, encrypted with a separate 100,000-iteration PBKDF2 key. A vault within your vault.
Unlock your vault with your fingerprint or face via Windows Hello biometrics. Falls back to your master password on any device that doesn't support it.
Attach PDFs, Office docs, images, archives, and more - up to 25 MB per file. Open with your system default app or export to disk. Sort by name, date, size, or type.
Full-text search and tag-based filtering across all your notes. Sort by date modified, date created, or title - always find what you need instantly.
A carefully crafted dark theme and a clean light theme. Auto-save after every edit. Resizable panels. Word wrap toggle. Word count always visible.
Configurable inactivity timeout wipes the vault key from memory automatically. Walk away from your desk without a second thought.
Everything lives in one portable .vnote file. Back it up to a USB drive, a hard disk, anywhere - without your password it's indecipherable noise.
No accounts. No servers. No telemetry. No subscriptions. Your data never touches the internet unless you choose to put it there.
Journalists protecting sources. Lawyers keeping privileged notes. Security researchers. Executives. Writers. Or anyone who simply believes their private thoughts should stay private.
"The best vault is the one that can't be broken, even if the file is stolen."
Source notes that can never be subpoenaed from a server that doesn't exist.
Vulnerability notes, credentials, and findings in an auditable, offline vault.
Your diary. Your ideas. Your life. Yours alone.
No subscription. No renewal. Pay once, own it for life.
