 # Summary
 Interoperable Private Attribution (IPA) is an API for privacy-preserving advertising attribution. Attribution means counting the number of "conversions", for example purchases, that follow an ad interaction, for example viewing an ad. IPA preserves privacy by using cryptography and a network of helper parties who are trusted not to collude or be collectively coerced. See https://github.com/patcg-individual-drafts/ipa
