Calculator data

Calculator values and results are processed in your browser. They are not sent to Home Access Lab, stored in a database, or used as measurement events. We do not request a name, phone number, or email to use the calculators.

Technical data

The hosting provider may process technical information needed to deliver and protect the site, such as IP address, browser, requested pages, and timestamps.

Analytics

Cloudflare Web Analytics is active through automatic setup. Its performance beacon measures page loads and performance to report page views and visits. Reports can use dimensions such as country, path, referrer, device type, browser, and operating system. According to Cloudflare, the service does not log query strings, use cookies or local storage for usage metrics, or track a person across its customers’ properties.
