Tools
The carrier checker, crate calculator and search run entirely in your browser. Measurements you type are not sent to us; they only appear in the page address so you can copy a link.
Storage
If you pick a light or dark theme, we save that choice in your browser's local storage. Nothing else is stored.
Ads and analytics
We may use Google AdSense and privacy-friendly analytics. Google and its partners may use cookies to show ads based on your visits to this and other sites. You can opt out of personalised ads at Google Ads Settings.
Affiliate links
Links to Amazon are affiliate links, and Amazon may set cookies when you click them.
