Privacy & cookies

This website keeps the calculator simple: enter measurements, see a result, and print it if you want a copy.

Calculator measurements

The calculations run in your browser. The application does not send your entered wall measurements to an application database or analytics service. Measurements, optional obstacle dimensions and units are held in page memory and, when available, in this tab’s session storage so they survive navigation to another tool or the guide. Reloading the page starts a fresh example; closing the tab normally clears its session storage, although browser session restoration may restore it. The application does not use cookies, persistent local storage, or an external server for this feature. If browser storage is blocked, links still work, but another page starts with the example measurements. A printed or saved PDF is under your control.

Hosting and access

The site is hosted through OpenAI Sites and is publicly available. Hosting and security services may process technical request data, such as an IP address and browser information, and may use cookies for access and security. Those services operate separately from the calculator.

Ads and analytics

No advertising or analytics scripts are installed in this version. The application does not set advertising cookies. This notice and any required consent controls will be reviewed before advertising or analytics is introduced.
