What we collect, and why
Waitlist. We collect your first name, email, city, age band, how you'd participate, the size of your crew, and the interests you tick. We use it to invite you, to decide where the first Basecamps go, and to understand who wants this.
Referrals. When you join through a friend's link, we record whose link it was so their place in line can move up. Your friend can see the number of friends who joined, but not your name or email.
Abuse prevention. We store a salted one-way hash of your IP address, never the address itself, to rate-limit sign-ups and to count referrals from distinct devices. We also store the country your request came from and any campaign (UTM) tags in the link you used.
No ad trackers. There are no third-party advertising pixels on this site. We never sell or share the list.
Your choices. Email hello@compoundinterest.club to get a copy of your data or to have it deleted, and we will do it within 30 days. Every email we send has an unsubscribe link.
Where it lives. Data is stored in Cloudflare D1.
