Privacy

Calculator inputs and results are processed in your browser. The site has no user accounts, backend calculator database or contact form.

Optional measurement

When configured by the publisher, Google Analytics 4 may measure page and calculator interactions, and Microsoft Clarity may help diagnose usability problems. Neither service loads until you allow analytics. If no integration identifier is configured, no consent banner or third-party measurement script is served.

Events are limited to the calculator identifier, calculation mode, unit system and actions such as copying a result or opening advanced options. Google Analytics receives only those approved fields, while Microsoft Clarity receives only the approved action name. Raw dimensions, quantities, prices, notes, result values and other typed text are never included in analytics events. Calculator controls are also marked for Clarity masking, and input boxes are masked by Clarity.

Your choice

Optional storage is denied by default. You may accept optional services, allow analytics only or reject all optional services. The choice is stored in your browser under material-totals-consent-v1. Use “Privacy choices” in the footer to review it. Clearing site storage also resets the choice.

Server records

The hosting provider may retain ordinary request logs such as IP address, requested URL, browser information and timestamps for security and operations. Hosting details and retention must be confirmed when a production provider is selected.

External links

Source links open third-party sites with their own privacy practices. No calculator input is added to those links.

Changes

This notice will be updated when providers, purposes or retention practices change.
