We only collect information needed to provide Delulu. Goals may be processed by an AI provider when you request an explanation. To improve the product we record first-party usage events (for example: a goal was typed, a receipt was viewed, a share button was clicked) against an anonymous browser ID, with your approximate country (worked out by our host from your IP address; the address itself is never stored). This includes the text of goals you type, even if you don’t finish. These events stay in our own database and are never sold or shared with advertisers or third-party analytics companies. Our host, Vercel, also counts anonymous page views with Vercel Web Analytics: no cookies, and we strip goal text and other query strings from page addresses before they are sent. Delulu is free; purchases made before it went free were handled by Polar as merchant of record. Public challenges and their updates are deliberately public; do not post sensitive information. Every receipt and board has an unlisted share link: anyone you give it to can see the goal, the score and the numbers behind it (never your name or account), and it is kept out of search engines.
