Frequently Asked Questions
What's the formula?
It checks for a single "@", at least one character before and after it, and a domain with a dot and a 2+ character suffix - the same shape as most real addresses.
Is my data sent to a server?
No - everything runs entirely in your browser with JavaScript. Nothing is uploaded.
