Secure Hub is an unlisted app: it won't show up in App Store search, but anyone can install it via these direct links.
Secure Hub is a place for everything you'd rather keep to yourself: project notes, documents, attachments and to-dos. Everything is encrypted on your device with AES-256-GCM before it is stored or synced. Your password never leaves the device.
Under the hood it's a full notes app: Markdown with live preview and Mermaid diagrams, wiki links and backlinks, tags, templates, a Kanban board, a calendar, a graph of your notes, canvas and drawings. Fully offline, compatible with the Obsidian formats.
