Privacy Policy

Last updated: October 18, 2026

Numbers you enter

Our calculators run entirely inside your web browser. The numbers you type aren't sent to our servers. A few calculators (such as the GPA and time card calculators) save your entries in your own browser's local storage so they're still there when you come back; you can clear them at any time by clearing your browser's site data. When you use "Share these results", your inputs are placed in the page address so you can send the link to someone.

Information collected automatically

Like most websites, our hosting provider (Cloudflare) may record standard server logs (such as IP address, browser type and pages requested) for security and to keep the service running. We use Cloudflare Web Analytics, which is cookieless, to count page views.

Advertising and cookies

This site is funded by advertising. We use Google AdSense, which may use cookies and similar technologies to show ads based on your visits to this and other websites. Google's use of advertising cookies lets it and its partners serve ads based on your browsing.

You can opt out of personalized advertising at Google Ad Settings, or visit aboutads.info to opt out of other vendors' personalized ads. See how Google uses data from sites that use its services.

Visitors in the EEA, UK and Switzerland are asked for consent before personalized ads are shown.

Affiliate links

Some pages include links to partner websites. If you click one, the partner may use cookies to record that you came from ToolsForNumbers, so we can be credited for a sign-up. Once you leave our site, the partner's own privacy policy applies. See our advertising & affiliate disclosure.

Children

This site isn't directed at children under 13, and we don't knowingly collect their personal information.

Changes

We may update this policy. Changes are posted on this page with a new date.
