What the site does
This guide serves static pages and locally hosted assets. It has no accounts, newsletter, payment interface or personal-information submission form. The site application does not set cookies or load third-party fonts. Its only persistent browser preference is the optional analytics exclusion described below; it has no saved reading history or bookmarking feature.
Search and experiment calculations happen in your browser. Search terms, selected journey stops and experiment settings can appear in the URL so a view can be shared. A link reveals those values to its recipient and query parameters may also reach the hosting service. The copy-link button writes the current address to your clipboard only when you activate it; it does not read your clipboard.
A pinned comparison stays in memory while the page is open. Reloading or leaving the page clears it. Shared experiment links include the current controls, not the pinned comparison; comparisons are not saved to an account or sent as analytics events.
Visitor statistics and your browser
Visitor statistics are disabled in this release. No analytics provider script is loaded and no analytics pageview request is made. A small local helper runs to honour the browser exclusion controls below, including on links that use ?analytics=off.
You can exclude this browser from future visitor statistics, even while statistics are disabled site-wide. The choice is stored under invisible-infrastructure.analytics.excluded in this browser’s local storage for this site. It is not an account, a visitor identifier or a cross-device setting. Clearing site data removes the preference; repeat the choice in each browser you use. Excluding a browser does not delete past statistics or prevent the hosting requests needed to deliver pages.
The exclusion control uses ?analytics=off; allowing statistics again uses ?analytics=on. The helper saves or removes only this preference, then removes only the analytics control parameter from the address while preserving other selections. Allowing statistics again removes a browser exclusion; it does not override the site-wide disabled setting, browser privacy signals or other safeguards.
Before loading a configured provider, and again for every attempted pageview, the integration checks the saved exclusion, Do Not Track, Global Privacy Control, automation indicators, the exact production address and excluded page types. If preference storage cannot be used, statistics stay off. It also skips statistics when the browser supplies a referring address containing query parameters, a fragment or login information, or when that address cannot be checked. Browsers identifying themselves as automated or headless are excluded; this is a filter, not proof that all other visits are human. Local and differently addressed preview copies do not load the provider.

Hosting and external sources
The published site is hosted by Vercel, which processes page and asset requests and may retain operational logs containing IP addresses, request URLs and browser information, independently of this site’s disabled analytics. See Vercel’s privacy policy. The local preview server does not save access logs.
Source links take you to independent websites with their own privacy practices. They open in a new tab with a no-referrer link setting. Ordinary internal links stay within this guide.
Advertising is disabled
The site displays no ads and makes no advertising requests. Inert placement hooks after component articles and the field guide reserve no advertising space and load nothing. If advertising is introduced, this notice will describe its processing and the privacy choices available.
Changes to this notice
This notice describes the current release. It will be updated when hosting, analytics, advertising or data-handling practices change.
