Calculator inputs stay in your browser

Everything you type into our calculators — income, expenses, tips, miles — is processed entirely in your browser with JavaScript. These numbers are never sent to our servers, stored, or shared. Reloading the page clears them.

What we collect

We do not require accounts and do not collect names, emails, or personal financial data. Like nearly all websites, our hosting provider (Cloudflare) processes standard server logs — IP address, browser type, pages requested — to serve the site and protect it from abuse.

Advertising

This site may display ads served by Google AdSense. Google and its partners may use cookies or device identifiers to show ads based on your visits to this and other sites. You can opt out of personalized advertising at Google Ads Settings, and learn how Google uses data at policies.google.com/technologies/partner-sites.

Analytics

We may use privacy-respecting, aggregate analytics (such as Cloudflare Web Analytics) to see which pages are used. This does not identify you individually.

Children

This site is not directed at children under 13 and does not knowingly collect their data.

Changes & contact

We'll update this page if our practices change. Questions: contact@confirmguy.com.
