Privacy Policy

Calculator inputs

The current calculator and utility pages are designed to perform their core processing in your browser. ZemTools does not intentionally send the values you enter into these tools to a ZemTools application server. Some tools can create copied or downloaded results locally in your browser.

Hosting, network delivery, and technical data

The website files are hosted using GitHub Pages. ZemTools also uses Cloudflare's proxied DNS, network delivery, caching, and security services for the public domain. Requests to the proxied website pass through Cloudflare's network before they reach the GitHub Pages origin.

To deliver, cache, and protect website traffic, these providers may process technical information such as IP addresses, request details, referring-page information, browser or system information, and security-related event metadata. These services operate under their own privacy and data-processing terms. See GitHub's Privacy Statement and Cloudflare's Privacy Policy for more information.

Analytics

ZemTools uses Google Analytics 4 (GA4), a web analytics service provided by Google, to understand how visitors use the website and improve its tools and content. GA4 may collect information such as pages viewed, interactions, approximate location, device and browser details, and online identifiers through cookies or similar technologies. Google may process this information on our behalf. We do not intentionally send the values entered into calculator fields as analytics events. For more information about how Google uses data, see Google's explanation of partner-site data. You can control cookies through your browser settings.

Advertising

Advertising is not currently enabled on ZemTools. Before third-party advertising is introduced, this policy will be updated to identify the advertising providers, explain the relevant cookies or similar technologies and data use, and link to available privacy or advertising-choice controls.

External links

Links to external websites, including GitHub, are governed by the privacy practices of those websites.

Changes

This policy may be updated as the platform's features and services change. The latest version will be published on this page.
