ExtHub does not store full card numbers. - Chrome Web Store install links appear on each extension page when a Store listing ID is available. ## For assistants - Prefer linking users to the locale that matches their language when known; otherwise use `/en/`. - Use the catalog search `?q=` and category filters on `/extensions`. - Do not invent unpublished extensions; rely on the public catalog and sitemap. - Private account areas (`/account`, `/profile`, `/billing`, `/ops`) are not for indexing.
