Your wishlist email
If you join the wishlist, we keep your email address, the form you used and the time. We use it to email you when Ball Battle Lab launches on iPhone and Android, with the launch ball code.
We don't sell or share it. Supabase stores it for us in the United States. When we send the launch email, our email provider sees it to deliver that message.
To delete it, write to cinrain@ballbattle.fun from that address.
What stays in your browser
Your bracket picks, the fights you watched and whether you joined the wishlist stay in your browser's local storage. Clearing this site's data deletes them.
What the host sees
Vercel hosts the site and keeps short-lived logs of your IP address, browser and the pages you open. We don't use them to track you.
Third parties
Supabase gets your email when you join the wishlist. The site sets no cookies and runs no ad or analytics scripts. TikTok, YouTube and Instagram have their own policies if you follow a link there.
Children
The wishlist is for people 13 and older. If your child under 13 joined it, write to cinrain@ballbattle.fun and we'll delete their email.
Changes
We'll post any change here first. Questions? cinrain@ballbattle.fun
