Sync & Accounts¶

Voltius is local-first. Sync is optional, and every option is zero-knowledge.

• OS keychain — most convenient, single device
• Master password — passphrase-locked vault
• Gist sync — free multi-device via your own GitHub Gist
• Cloud sync — Pro/Teams real-time sync
• Web portal — app.voltius.app for account management

For the cryptography behind all of this, see Security → Sync protocol.
