Website analytics
EMF Practical uses Google Analytics to understand visits and use of the website. Pages load Google's analytics script. Depending on browser settings and the site's analytics configuration, Google Analytics may use cookies and process page addresses, device and browser information, and interactions. A page address can include values in its query string.
Do not put sensitive health details or other private information in room names, shared tool links, or other URL fields. See how Google uses information from partner sites and the Google Analytics opt-out browser add-on.
Tools and saved layouts
Interactive tools use information you enter to display results. Browser-based calculation does not mean that every aspect of a visit is private: hosting and analytics requests still occur. Saved layouts may remain on your device, and shared links may contain your selected settings. Check each tool's controls before saving or sharing. Downloads you create are stored on your device.
Hosting and external services
Our hosting service processes the requests needed to deliver pages, including technical connection information. External fonts, linked resources, and provider websites may involve other services with their own privacy policies.
Product and affiliate links
Product links can take you to a seller or affiliate service. Those services may use tracking to attribute referrals and purchases. Review the destination's privacy and cookie information before providing information or buying.
