Private by design

No accounts, no cookies, no tracking. NuuMa doesn't store what you check. To run the tests, the address you enter goes directly from your browser to the public services named above. The only thing kept is a small daily counter in your own browser that keeps these tools free for everyone.

Questions, answered plainly

Is it really free?

Yes. No sign-up, no card and no catch. A daily limit per browser keeps the tools fast and free for everyone.

Do you store the websites I check?

No. NuuMa doesn't store or log what you enter. The address goes straight from your browser to the public services each tool uses.

Where does the data come from?

Google PageSpeed Insights and the Chrome UX Report; Google, Cloudflare and Alibaba Cloud public DNS; IANA and the official domain registries over RDAP; Certificate Transparency logs; and Mozilla's HTTP Observatory.
