Privacy Policy
What this site does — and does not — collect, and how advertising cookies are used here.
The short version
Last updated: October 4, 2026. This policy applies to carcaltune.com ("CarCalTune", "we"). Our calculators run entirely in your own web browser. We have no user accounts and no comment system, and we do not collect the numbers you type into a calculator. The site is supported by advertising (including Google AdSense), and those ad services use cookies as described below.
Your calculator inputs stay on your device
Every calculator on CarCalTune executes locally in your browser with JavaScript. The values you enter are processed on your device only — never transmitted to, stored on or logged by our servers.
Advertising and cookies (Google AdSense)
CarCalTune uses third-party advertising services, including Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies (including the DoubleClick cookie) enables Google and its partners to serve ads based on your visits. You can opt out of personalized advertising at Google’s Ads Settings page.
Analytics
We use Google Analytics to understand aggregate usage (pages visited, approximate geography). It does not receive your calculator inputs.
