PureUnits — practical tools, zero paywalls
PureUnits is an independent digital tools platform founded by Tugay Tufan. Our sole mission is to deliver free, fast calculators and converters for developers, digital marketers, and finance professionals worldwide.
The platform is funded exclusively through user-friendly, non-intrusive advertising (Google AdSense). There are no subscriptions, no enterprise upsells, and no third-party agency partnerships — just tools that work in your browser.

How we operate
Browser-first architecture
Most tools compute locally in your browser for speed and privacy. We minimise server-side data collection by design.
Ad-supported, always free
Google AdSense covers hosting and development costs. Ads are placed to stay out of your way while keeping every tool free. Details are in our Privacy Policy and Cookie Policy.
Founded by Tugay Tufan
PureUnits is built and maintained as a standalone product — focused on useful utilities, clear UX, and sustainable ad-based revenue rather than agency services or regional branding.
