Short version: the subwoofer box calculator runs entirely in your browser. We do not need an account, and we do not want your build sheet.
Dimensions, wood thickness, port geometry and displacement values you type into the calculator are held in your browser memory only for as long as the page is open. They are not transmitted to us and are not stored on any server.
We may use privacy-respecting, aggregate page analytics to understand which tools are used. That data does not identify you individually, and we do not set advertising or cross-site tracking cookies.
Fonts and images may be delivered by content delivery networks, which by their nature see your IP address as part of serving the request. We do not sell, rent or share personal data with advertisers or data brokers.
Because nothing you enter leaves your device, clearing or reloading the page removes it. If you contact us by email we keep that correspondence only as long as needed to answer you, and you may ask us to delete it at any time.
If this policy changes we will update the text on this page. Continued use of the site after a change means you accept the revised policy.
