The legally binding privacy policy is available in German. This website uses no tracking cookies. The Book Finder runs locally in the browser and does not transmit search entries. For anonymous usage statistics, only aggregated events such as page views, website entries, Book Finder uses/results, PDF opens and external clicks are counted on the website’s own server. Referrer information, where supplied by the browser, is immediately reduced to broad source categories such as Google, Instagram or Direct / no referrer; the full referrer URL is not stored. An aggregated active-page-time value may also be recorded. No visitor IDs, fingerprints, IP addresses or individual click paths are stored in the statistics database.
