No Email Needed

Email belongs to apps, not utilities

If you're using a service that needs to remember you — your bank, your email client, your photo library — giving them an email address makes sense. They have something to send you. They have your data to protect. They need a way to reach you when something goes wrong.

A unit converter doesn't have any of that. Neither does a tip calculator, a JSON formatter, or a QR code generator. There's nothing to remember. There's nothing to send. The tool runs once and the session is over.

So we don't ask for one. There's just nothing for it to do.

What it would cost you

Asking for an email up front isn't free for the visitor. It adds friction at exactly the moment you wanted to do something quick. It also creates a small obligation — now you're on a list, somewhere, and you'll get a welcome email, then a follow-up, then a "we miss you" message six months later.

None of that is helpful when all you wanted was to convert 35 km/h into mph.

What we send

Nothing. We have no newsletter. No drip campaign. No "tips and tricks" emails. We don't collect addresses because we have nothing to mail.

If you want to keep up with new tools we add, the homepage works fine — pop over once in a while and see what's new. That's about as ceremonial as we want it to be.
