Encrypted backup & restore
Everything this tool stores lives in this browser and nowhere else — that is the promise, and the risk. Clear your site data or switch machines and it is gone. Pro encrypts all of it under a passphrase you choose and hands you the file, so you can move it or keep it safe. It never leaves your device.
