Leynir Notes is a privacy-focused note-taking app for Windows that stores everything in an encrypted vault on your own machine. There is no cloud, no account, no sync, and no subscription - your notes never leave your device.
Encryption & Security
All notes are encrypted with AES-256-GCM before they touch disk. The encryption key is derived from your master password using a key derivation function - meaning even if someone gets hold of your vault file, the contents are unreadable without the password. Windows Hello (fingerprint, PIN, or face recognition) provides a convenient second unlock layer without weakening the underlying encryption. Biometric data never leaves your device.
Your file, your rules
Everything is stored in a single portable vault file on your filesystem. Back it up to an external drive, an encrypted USB, or keep it local — the choice is yours. No proprietary sync service, no vendor lock-in.

Who it's for
Leynir Notes is built for people who want a simple, fast note-taking tool and are not willing to hand their data to a cloud service to get it. If you have ever felt uneasy about Notion storing your notes on their servers, frustrated by Standard Notes pushing a subscription for basic encryption, or wished Obsidian offered encryption at rest - Leynir Notes was built for that gap.
leynir-notes added Leynir Notes as alternative to Notion, Obsidian, Joplin and Standard Notes
