Terms of use
Last updated October 31, 2026.
A new app
Grailhouse is new. It may change, have bugs or be down for a while. Features and allowances (such as the monthly card reads) can change. Keep your own copy of anything important: Cards → All cards → Export CSV downloads your collection.
The free trial and plans
Each household gets 14 days of everything, free, with no card needed. After that, keeping on adding and scanning cards takes a plan (Collector, Family or Ultimate, priced on the Pricing page), paid monthly through Stripe. A plan renews each month until you cancel it in Settings → Plan; cancelling stops the next charge and the plan runs to the end of the month already paid. Without a plan your cards stay, and you can look at them, search them and export them. If prices change, you'll be told before your next charge.
Your login
You must be 18 or older to make a login. Keep your password to yourself; you're responsible for what happens under your login, including how children in your household use it. One invite code is for the person it was given to.
Prices and values are estimates
Values, price ranges, offer suggestions, break math and sell signals are estimates from past sales and outside sources, and they can be wrong. Grailhouse isn't financial advice. Check before you buy, sell or trade, and decide for yourself.
Using it fairly
- Use Grailhouse for your own collection and selling.
- Don't try to get into other households' data, overload the service, or get around the AI allowance.
- Don't upload anything you don't have the right to, or anything illegal or abusive.
- The shared checklists are for identifying cards in Grailhouse. Don't copy them out in bulk.
Accounts that break these rules can be paused or removed.
Your content
Your photos and data stay yours. You let Grailhouse store and process them to run the service for you (including sending photos and questions to its AI provider). See the privacy policy.
No warranty
Grailhouse is provided as is, without warranties. To the fullest extent the law allows, Grailhouse and the person who runs it aren't liable for losses from using it, including buying, selling or trading decisions, lost data, or downtime.
Trademarks
Card brands, leagues, teams and marketplaces named in Grailhouse belong to their owners. Grailhouse isn't affiliated with or endorsed by them.
