Frequently Asked Questions

Can BrainVault sync across devices?

BrainVault doesn\'t include built-in cloud sync to preserve privacy. However, you can use any file sync tool (Git, Dropbox, Syncthing, etc.) to sync your notes folder across devices. Your data, your choice.

Does it work offline?

Yes! BrainVault is offline-first. Once installed, you never need an internet connection. Search, edit, link notes—everything works perfectly offline.

Is my data encrypted?

Your notes are stored as plain Markdown files on your device. You can encrypt them using your OS-level encryption (FileVault, BitLocker, LUKS) or a third-party encryption tool.

Can I import from Obsidian or Notion?

Yes! Obsidian vaults work immediately (same markdown + wiki links). For Notion, export as Markdown, then open in BrainVault. Links may need minor adjustments.
