What stays on this device

Learn saves sessions, response text, question versions, attempts, bookmarks, flags and theme preferences in this browser’s IndexedDB. It sends no personal learning record to a server. Public search and filters appear in URLs and browser history; do not enter personal information in search.

Browser storage is separate for learn.eliexplains.org and eliexplains.org. Use the explicit export/import tools in Progress to transfer compatible history. Exports contain your responses and can include original migration archives; keep them private. Clearing site data removes local progress. A storage failure switches to temporary memory with a visible warning.

Hosting and correspondence

Cloudflare serves the site and may process technical request information. No advertising or runtime AI service is used. Fonts and app assets are served locally. Source instructional images may be served by their original publisher where recorded; opening source links sends normal request information to that publisher. Emailing a correction shares the message and email metadata with the operator.
