Calculator inputs
Calculations run in your browser. The calculator does not send the measurement values you type to a calculation server. Copying results uses your device's clipboard; printing uses your browser's print dialog.
Website analytics
We use Google Analytics to understand visits and use of the roof pitch calculator. Analytics may use cookies and process information such as page URLs, browser and device details, and interactions. Calculator events describe the input mode, unit system and actions such as copying or requesting a print; they do not include the raw measurement values you type.
Google handles analytics data under its own privacy policy. You can use Google's analytics opt-out browser add-on or browser controls to manage collection. Opening this site with ?analytics=off suppresses our analytics for that browser tab's session when session storage is available; it does not remove data collected earlier.
The current site does not load Microsoft Clarity or advertising scripts. We will update this policy if those integrations change.
