Privacy policy

What data Booster Bullpen collects, the analytics and affiliate links in use, how account data is stored, and how to request deletion.

Booster Bullpen collects only the information needed to provide the service: your email address, your password (hashed by Supabase Auth), your watchlist entries, and your vault items. We do not sell your data.

Analytics

We use PostHog for anonymous product analytics — page views, feature usage, no PII beyond your authenticated user id. You can request your analytics record be deleted by emailing [email protected].

Affiliate links

Buy buttons (TCGplayer, eBay, Card Kingdom) include affiliate codes. We may earn a commission at no cost to you. We never share your identity with merchants.

Account deletion

Email [email protected] from your account address to request account and data deletion within 30 days.
