What you type into calculators
Calculators run in your browser. The numbers you enter aren't sent to us or stored. If you copy a result link, the inputs are in that link, so only share it with people you trust.
VIN checks
The VIN you enter is sent to the US government's NHTSA vehicle database to look up the plant. We cache the result for 30 days to avoid repeat lookups. We don't link it to you.
Analytics
We use Google Analytics 4 and Cloudflare Web Analytics to count visits and see which tools are used. Cloudflare Web Analytics doesn't use cookies.
Advertising
Google AdSense shows ads on this site and may use cookies to choose them. Visitors in the EEA, UK and Switzerland are asked for consent first. You can change ad personalization at Google's Ad Settings.
