What cookies are
Cookies are small text files stored by your browser. They help a site remember choices or measure visits. This page explains what Virtualization API uses.
Types we use
Essential — required to remember whether you accepted or rejected non-essential cookies. The site remains usable if you reject analytics.
Analytics — optional cookies that help us see which lesson and field-note pages are read, so we can improve curriculum pages. They load only after Accept.
Cookie table
| Name | Purpose | Duration | Provider |
|---|---|---|---|
virtualization-api-cookie-consent | Stores Accept or Reject choice for the banner | 1 year (localStorage) | Virtualization API |
_va_analytics | Counts page views on lesson and field-note URLs after consent | 6 months | Virtualization API (first-party) |
Managing cookies
Use Accept or Reject on the banner. You can clear site data in your browser settings at any time. Rejecting does not block browsing, forms, or lesson pages. For broader controls, use your browser’s cookie settings or private browsing mode.
Third-party cookies
Embedded fonts may be requested from Google Fonts; that request may allow Google to see your IP address. We do not embed third-party advertising cookies. Image hosts (for chart photography) may receive standard request logs when an image loads.
Impact of disabling
Disabling essential storage may cause the consent banner to reappear on each visit. Disabling analytics only means we will not record aggregated page-view counts. Training content and contact forms continue to work.
