Description by Lockbook (from Google Play)
Lockbook is an end-to-end encrypted notes app for writing, sketching, storing files, syncing across devices, and collaborating in real time. Your notes are encrypted before they leave your device, so even we can't read them.

Lockbook is 100% open source:
https://github.com/lockbook/lockbook

Fast & Native:
We built Lockbook for everyday use because we use Lockbook every day. Our native apps feel at home on every platform, with fast sync, offline support, and a polished Markdown editor for serious notes.

Secure:
Keep your thoughts to yourself. Lockbook encrypts your notes with keys generated on your devices. Only you and the people you share with can access your notes, folders, sketches, and files.

Private:
Know your customer? We sure don't. We don't collect your email, phone number, or name. We don't need a password. Lockbook is for people with better things to worry about than privacy.

Collaborative:
Share folders, edit notes together, and see live updates from collaborators without giving up end-to-end encryption.

Open:
Write in Markdown, sketch in SVG, and keep your work in formats you can actually use.

Honest:
Be the customer, not the product. We sell a note-taking app, not your data.

Developer Friendly:
The Lockbook CLI fits right into your favorite chain of piped-together Unix commands. Search your notes with fzf, edit them with vim, and schedule backups with cron. When scripting doesn't cut it, use our Rust library for a robust programmatic interface.
