A quick ask from the person behind the Anomadex: if you allow analytics, Google Analytics shows me which places, phenomena and searches you're most curious about. That tells me which regions and sources to add next and what to make easier to find. It never sees your name or anything you send me, and nothing is set unless you say yes. Privacy
