Your numbers stay on your device

Every calculation on LazySums runs in your browser. The dates and numbers you type aren't sent to us or stored by us. There are no accounts.

Share links

If you use “Copy link to this result”, the values you entered are added to the web address so the result can be reopened. Anyone you send that link to can see those values. Don't share a link containing anything you'd rather keep private.

Hosting

The site is hosted by Netlify, which may keep standard server logs, such as IP addresses and the pages requested, to run and protect the service.

Visitor statistics

We use Cloudflare Web Analytics to count visits and see which pages are used. It doesn't use cookies and doesn't track you across other websites. It never sees the numbers you type into a calculator.
