Privacy Policy

Last updated: November 10, 2026

This Privacy Policy describes how whatcanweknow.com (“we”, “us”) handles information when you use our website.

Information We Collect

Tool inputs: All calculations on this site run locally in your browser. The numbers and dates you enter into our tools are not transmitted to or stored on our servers.

Automatically collected data: Our hosting provider (Cloudflare) processes standard technical information such as IP address, browser type and requested pages in order to deliver the site and protect it from abuse.

Site analytics: We use Cloudflare Web Analytics to understand aggregate traffic — page views, referring sources (including search engines and AI assistants), and device- or country-level breakdowns. It is cookieless: it does not set advertising or tracking cookies, does not build cross-site profiles, and never receives the numbers or dates you enter into a calculator. We use these totals only to decide which tools and guides to improve. This analytics is separate from the advertising cookies described below.

Advertising and Cookies

We display advertisements served by Google AdSense. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. These are the only advertising cookies on this site; Cloudflare Web Analytics does not set cookies.

• Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also manage cookies through your browser settings.

For more information about how Google uses data, see Google’s Privacy & Terms.
