Number Privacy Policy
Last updated: November 6, 2026
Number Nest is a free calculator site. It is built to need as little of your information as possible.
No accounts, and your numbers stay in your browser
There are no user accounts on this site. The calculators run entirely in your web browser: the figures you type into a calculator are not sent to or stored on our servers.
Anonymous usage statistics
We collect aggregate, non-identifying usage statistics so we can see which tools help people and fix what doesn't work: pages visited, which calculators are used, approximate time on a page, device/browser type, and the referring site. These statistics are stored without names, email addresses, or account identifiers, and they are never sold.
Advertising and cookies
Ads on this site are served by Google AdSense and Adsterra. Those networks may use cookies or similar technologies to serve ads, measure their performance, and — where permitted — personalize them. You can control cookies in your browser settings, manage Google ad personalization at Google Ads Settings, and learn how Google uses data from sites that use its services at policies.google.com.
If you email us, we receive your email address and message and use them only to reply.
Children
These are general-audience tools. We do not knowingly collect personal information from children.
Changes and contact
We may update this policy; the current version will always be on this page. Questions: autoboostteam@gmail.com.
