Audience measurement
We measure page views and product-link clicks using a random identifier in this tab’s session storage. It expires after 30 minutes without measured activity. We collect the publication, public page path, product identifier, referring hostname, and event time. Query strings, form inputs, emails, and raw IP addresses are not stored in our analytics database. Cloudflare processes connection information to deliver and secure this service, including temporary abuse prevention. Events are retained for up to 90 days, with hourly cleanup. We honor Global Privacy Control and browser Do Not Track. Blocking scripts or storage may reduce measurement accuracy. Measurement is for our private editorial reporting and does not identify unique people.
What this site stores
The calculator and filters run in your browser. This site does not save their inputs, set tracking cookies, or send those inputs to a server. Downloads are available without registration.
Optional video playback
Video cards initially load local poster images. This site makes no YouTube embed request until you select Play. Playing a video loads a YouTube privacy-enhanced player from youtube-nocookie.com; YouTube then receives connection data and may process playback information under its own policies. Privacy-enhanced mode does not make playback anonymous. The Watch on YouTube link opens the provider directly.
Hosting and external links
A hosting provider may process standard request data, such as IP address and browser information, to deliver and secure pages. Linked third-party providers have their own privacy policies. Affiliate links, when used, may allow those providers to attribute purchases using their tracking technologies.
Contact
If you contact the publication by email, the email provider processes the message and any information you include. Please avoid sending sensitive personal information.
