May we use Google and OpenAI measurement to see which ads lead to book downloads and donations? You can download and donate either way.

How we use this data

With your permission, Google Analytics and Google Ads connect visits and ad clicks with donation amounts and refunds to measure advertising results. We retain the identifiers needed for refunds for up to 90 days. Personalized advertising stays off. Donation events contain no names, email addresses or payment details. Rejecting cookies keeps measurement limited and cookieless. Stripe processes all payments. You can change your choice here; withdrawal does not erase data already sent.

OpenAI can use an ad click reference, a browser identifier, and event information to match downloads and paid donations to ads. For donations we send the confirmed amount and currency. You can withdraw your choice in Privacy settings.
