Privacy Policy
The short version: your inputs stay in your browser, we count pageviews without cookies, and ads are served by Google.
What you type into calculators
Calculator inputs, your loan amounts, birth dates, body measurements, are processed in your browser by JavaScript. They are not sent to our server, stored, or logged. Closing the tab erases them.
Analytics
We run our own lightweight pageview counter. When a page loads, your browser sends us the page path and the referring site. We derive a temporary daily identifier from your IP address and browser signature to estimate unique visitors; it is a one-way hash that rotates every day and cannot be traced back to you. We do not use analytics cookies, we do not build profiles, and we do not share this data with anyone.
Advertising
Ads on this site are served by Google AdSense. Google and its partners may use cookies or device identifiers to show ads based on your prior visits to this and other websites. You can opt out of personalized advertising at Google Ads Settings. For more on how Google uses data from sites that use its services, see Google's partner sites policy.
Contact form
If you use the contact form, we receive the name, email address, and message you submit, and we use them only to reply. They are not added to any mailing list.
Server logs
Our hosting provider keeps standard web server logs (IP address, requested URL, timestamp) for security and debugging. These rotate automatically.
Children
This site does not knowingly collect personal information from children under 13.
