The short version: this site barely touches your data.
Fandom Universe is a static website. It sets no accounts, runs no comments, and embeds no advertising trackers of its own. If basic, privacy-respecting visit statistics are used, they are aggregate counts only — pages viewed, not people profiled.
Outbound links go to retailers such as Amazon; once you leave this site, the retailer's own privacy policy governs what they collect. Affiliate links may include a tracking tag so the retailer can credit a commission — that tag identifies this site, not you personally.
Questions about this policy can be raised through the site's contact channels when they open.
