That’s a valid concern for public computers. If you need that hybrid accessibility without losing the 'local-first' spirit, check out Syncthing or Tailscale. They let you access your home machine's Obsidian vault as a network drive securely. It’s a bit more setup, but it beats the 'entrepreneurial' bloat of SaaS tools that might not exist in two years. Sometimes a simple spreadsheet is the best answer, but for long-term knowledge, sticking to plain files is a gift to your future self.
