Your experiments
stay with you.
Effective 14 November 2026.
Your experiments stay in your browser
Text entered into the labs and all demonstration calculations stay in your browser. They are not sent to a language-model service. Quick-check answers and opened term definitions are not saved or reported. This site does not ask for an account, payment details, or an email address.
Optional reading progress
When you press “Mark lesson as read,” the site saves lesson identifiers in this browser’s local storage under llm-field-guide-progress-v1. It also saves that lesson and its learning path under llm-field-guide-resume-v1 so the home page can suggest where to continue. These records are not cookies and are not transmitted by this site. They remain until you clear them or your browser removes them. A different browser or site address has separate storage.
Clearing reading progress does not remove your analytics exclusion below.
Returning to your place
To return from a lesson or experiment to the place you left, the site keeps up to 24 recent page snapshots in this tab’s session storage under how-llms-work.return-navigation-v1. Each snapshot contains a local page address and title, including search or path filters in the address, a scroll position, open explanation sections, and the link used. Local timestamps and page-entry references connect those snapshots and limit their lifetime. They contain no lab text or quiz answers and are not transmitted by this site. Snapshots expire after 24 hours. Session storage normally ends when the tab closes, although browsers can restore a tab’s session. Clearing reading progress leaves this temporary return information unchanged.
No analytics or active advertising
This release has no analytics service, advertising scripts, tracking pixels, third-party font requests, or embedded videos. It does not report page views or interaction events. Advertising is disabled. There is no advertising consent banner because no advertising provider is loaded.
You can save an additional analytics exclusion for this browser. The setting uses llm-field-guide-analytics-excluded-v1 in local storage and is not sent anywhere. It applies to this browser and site address until you remove it or the browser clears site data. You can also add ?analytics=off to a page address, or &analytics=off if it already has a query. The site saves the exclusion and removes that control parameter from the address bar when JavaScript runs.
Analytics and advertising are off for everyone.
Removing the exclusion does not enable analytics or grant advertising consent. The site also checks Global Privacy Control, Do Not Track, and browser automation signals. An unavailable preference store keeps analytics blocked. If storage cannot save your exclusion, the status above explains that it applies only to the current page. These preferences do not prevent the normal page requests needed to use the site.
Search and shared addresses
Search runs in your browser using a search index served by this site. Search terms and selected filters appear in the address so you can return to or share the same view. Lesson and learning-path links can also carry identifiers in the address. Those addresses may be retained in browser history or become visible when copied, shared, or requested from the host. Avoid putting private information in a search or shared URL.
Network requests and hosting
Your browser requests pages, styles, scripts, images, fonts, and local learning or search indexes from the site’s host. Syne and Inter font files are served locally; loading them does not contact Google Fonts or another font service. The host may process connection information such as IP addresses and requested addresses as part of serving the site. Hosting logs are separate from the browser-local preferences described here; this release makes no host-specific retention claim.
External references
Source and video links open other websites with their own privacy practices. We link to these materials rather than embed them. Following a link sends a request to that website, and your browser may send referrer information according to its policy. No outbound-link clicks are recorded by this site.
Before any future integration
Analytics and advertising cannot be switched on by these preference buttons. A future integration would require a reviewed implementation, updated disclosures, and any applicable consent controls before it loads. Declining or withdrawing permission must keep the relevant provider from receiving further requests.
