About Lockbook

Lockbook organizes notes and drawings in folders and encrypts them on your device. Notes use Markdown and drawings use SVG, which gives you familiar file formats when opening exported material in another tool. The app supports sharing by invitation, so a selected note can become a shared reference. It suits people who want to keep personal writing and sketches together and occasionally share a folder or document with someone working on the same project. You can start with a note and add visual material as the idea develops.
