Made by a dad who collects with his kids.
Grailhouse started as the app I wanted for my own family: one place for everyone's cards, what we paid, what they're worth, and which trades were fair.
- One family login. Kids don't sign up.A parent makes the account. Each kid is added inside it with a first name and the teams they like. Kids have no email, no password and no profile anyone else can see.
- You decide which trades go throughTurn on “Trades need a parent's OK” for any kid. Their trade waits until you approve it with your parent PIN, right there or later. Trade check gives them a plain answer first, so they learn what a fair trade looks like.
- Grown-up settings stay lockedThe parent PIN guards the settings that matter: trade approval, who is a kid and who isn't, the PIN itself, and anything the in-app helper would do for a grown-up.
- Their cards stay in your familyNo other family sees your cards, photos, costs or kids' names. Grailhouse doesn't show ads and doesn't sell or share your information. Card photos are read by Anthropic's Claude to identify the card, under terms that keep them out of model training. You can delete everything from Settings at any time. Read the privacy policy.
- It teaches the hobbyKids see what their cards sell for, which ones are short prints, and why a numbered parallel is worth more than the base. Set goals and want lists give them something to chase that isn't another blaster.
- Room for everyoneThe Family plan has room for six collectors under one login; Ultimate has ten.
