Sync your contacts between devices without storing them on a server. The passphrase encrypts your contacts in your browser — the server never sees them in plain text. (In this demo, passphrase generation and the QR code really work, but actual contact transfer needs a real account.)
Write the passphrase down. It cannot be recovered, since it never touches our server — if you forget it, you'll need to create a new one and re-sync all your devices with it.
Open this same page on your other device. Scan the QR code above with its camera, or type the passphrase in below.
Not available in demo — needs a real IMAP account.
