The short version
We do not ask you to create an account. We do not run a newsletter signup. We do not collect names, addresses or payment details, because there is nothing here to buy. The calculators run entirely in your browser.
Calculators and the data you enter
That includes the drawer load calculator, the fit planner, the foam calculator, the truck box fit finder, the gauge converter and the cost per liter calculator.
Server logs
Like essentially every website, the server that delivers these pages records standard technical request information: IP address, the URL requested, timestamp, referring page and user agent string. This is used to keep the site running and to understand which pages are being read. It is not combined with anything else, not sold, and not used to build a profile of you.
Cookies
The site itself does not set cookies to identify or track you. It has no login, no cart and no personalization, so there is nothing for a first-party cookie to remember.
Third-party services embedded on a page, including advertising, may set their own cookies or similar identifiers and may use them to measure or personalize what they show. Those services operate under their own privacy policies and their own controls, which you can also manage through your browser settings and your device's advertising preferences.
Your choices
Your browser gives you meaningful control here, and this site is built to keep working when you use it:
- Block cookies or third-party storage. The site functions normally.
- Block JavaScript. Every page remains readable. Calculators show their formula so the
method is still usable on paper.
- Use tracking protection or an ad blocker. No content is withheld and no interstitial
asks you to disable it.
- Send Do Not Track or Global Privacy Control signals. We do not sell personal information
in any case.
Links to other sites
Sources and references link to manufacturers, standards bodies and government sites. Once you follow a link, that site's privacy policy applies, not this one.
Children
This site is written for a trade and hobbyist audience and is not directed at children under 13.
Changes
If this policy changes materially, the date at the top of the page changes with it.
