Your plan data
MongoDB explain documents you paste or upload are processed entirely in your browser. They are never transmitted to any server operated by this site. The JavaScript that parses and analyzes your plan runs locally in your browser tab; no network request is made containing your plan data.
Plan data is held in browser memory only for the duration of your session. Clicking New plan clears all derived data. We do not use localStorage, sessionStorage, or cookies to store your plan data.
Advertising
This site displays advertising provided by third-party ad networks. Our advertising partners may collect standard browsing data — such as page views, ad impressions, and ad interactions — using cookies and similar technologies, in accordance with their own privacy policies. This browsing data does not include your MongoDB plan content.
To learn how our advertising partners use data, please review their respective privacy policies. Common partners include Google (see Google Privacy Policy).
Analytics
This site uses Cloudflare Web Analytics to measure aggregate page traffic (page views, referrers, approximate geography). Cloudflare Analytics is privacy-focused and does not use cookies or fingerprinting. No query text, field names, or plan data is included in analytics events.
Cookies
This site does not set first-party cookies. Third-party advertising scripts may set cookies per their own policies.
