A private and secure markdown knowledge base and notes app with cloud sync
🌟 Leaf Note — A dual-platform app focused on Markdown note-taking and knowledge management, supporting WebDAV / iCloud / OneDrive sync, end-to-end encryption, and fully offline functionality.
1. 🎨 Beautiful Design & Personalized Themes
The first time you open LeafNote, you’ll be instantly captivated by its minimalist and elegant interface — from smooth interactive animations to meticulously crafted card-based layouts, every detail has been thoughtfully refined. We offer multiple themes: whether it’s an eye-friendly dark mode for late-night writing or a bright, clean theme for daytime productivity, LeafNote delivers an immersive note-taking experience.
2. 🔒 Bank-Grade Security: Dual Encryption for Notes & App
Security is at the core of our design philosophy:
- Note Encryption: AES-256 encryption algorithm with user-defined passwords ensures your private content remains completely confidential;
- App Lock: Secure the app with fingerprint authentication or a custom password to prevent unauthorized access. Even if your phone is lost or stolen, your knowledge assets remain fully protected.
3. ☁️ Cross-Device Sync: Access Your Note Universe Anytime, Anywhere
Break free from device limitations — we support three major cloud services:
- OneDrive / Dropbox: Sign in with one click for automatic synchronization — ideal for users accustomed to international cloud storage;
- WebDAV: Compatible with private clouds (e.g., Synology, Nextcloud, JiaNuoYun), meeting the needs of advanced users.
All sync operations use TLS-encrypted transmission, ensuring secure, worry-free data flow between cloud and local devices.
Support for multiple data sources — configure and freely switch between several cloud servers.
