Your shelf stays with you.

Stored on this browser.

Saved resource IDs, your tool-comparison selection, light/dark preference, and self-marked learning progress are saved in localStorage. They do not sync to another device or account.

• Use “Clear saved items” on the Saved page to empty your reading shelf.
• Remove selected tools in Compare, or clear the comparison tray.
• Uncheck learning steps to reset their progress.
• Clear site data in your browser to remove all local preferences.

Analytics and email collection.

This site does not include analytics, advertising scripts, newsletter submission, sign-in or a backend that receives your saved items. Full-text search uses the static Pagefind index served with the site. Cloudflare Pages receives ordinary page and asset requests, which can include IP address, browser information, requested URL and request time, and processes them under its hosting policies. These hosting requests are separate from your browser-only reading shelf.

External links are separate.

Opening an original source takes you to that publisher, whose own policies and collection practices apply. This explanation covers the static library and its browser storage.

Storage may be unavailable.

Private browsing, browser settings, or storage limits may prevent persistence. In that case, use ordinary browser bookmarks; the content remains accessible without an account.
