Units Conversion
A privacy-first units converter, multilingual from day one. Coming from Ultim8Soft. We're building it now.
What it'll be
Conversion across the categories you reach for most: length, weight, area, volume, temperature, pressure, time, data sizes, and energy. Multilingual from the first release, the way the developer tools site is. Browser-first, the way the developer tools site is. You'll type a number, pick the source and target units, and see the result. That's the whole shape of it. No login, no syncing, no "premium tier" wall behind the temperature converter. If we add currency conversion later, it'll be the one place data might need to come from outside your browser — and we'll be upfront about that boundary when we ship it.
Why we're building it
Look at what's out there: most online unit converters log your queries. Some of them sell that data, some of them just sit on it, but the calculator-as-tracker pattern is everywhere. A units converter is a calculator. A calculator shouldn't phone home. The math fits in a few hundred lines of JavaScript and runs faster than the network round-trip a server-side converter would need anyway. So we're building one that doesn't ship your inputs anywhere, doesn't show ads keyed off what you converted, and doesn't try to upsell you on a Pro subscription with three extra unit categories.
Want to hear when it ships?
Drop us a line. We don't run a newsletter or a "join the waitlist" form because we don't want to be in the business of holding a list of email addresses. But if you say hello, we'll remember to ping you back when the converter goes live.
