Calculator data

Calculator entries and results are processed in your browser. They are not sent to Grade Workbench, saved on our servers, or included in analytics events.

Analytics

We use Cloudflare Web Analytics to understand page views, general traffic patterns, device types, countries, and site performance. We also record a limited set of product events, such as whether a calculator was started, produced a result, showed a validation error, or whether predefined feedback was submitted.

These events do not include calculator entries, results, names, email addresses, user IDs, or free-form text.

Infrastructure

Cloudflare provides hosting, security, analytics, and product-event storage. In providing these services, Cloudflare may process standard request data such as your IP address, browser information, and request timing.

Product-event data is retained for no more than three months.

Cookies

We do not use cookies for analytics, advertising, or personalization. Cloudflare may set strictly necessary cookies when needed to provide security and protect the site from abuse.
