The Hobby Treasury
Privacy Policy
Last updated 10 September 2026
The Hobby Treasury helps collectors scan cards and collectibles, estimate grade and value, and keep a private vault. This page explains what we store and what we never do.
What we collect
- Phone number or email. You sign in with a one-time code, so we store the phone or email you use to recognize your account and deliver that code. There is no password.
- Your collection. Photos you upload of cards and collectibles, titles, notes, grades and values the app estimates, vault lists, Treasure Hunter searches, Store and Trading Floor listings, and messages you send to other members.
- Membership billing. If you join Treasury Membership, Stripe processes the payment. We keep membership status on your account; card numbers stay with Stripe.
What we never collect
- No contacts book.
- No precise location for advertising.
- No browsing history outside the app.
- We do not sell your information to advertisers or data brokers.
How your information is used
Only to run The Hobby Treasury for you: sign you in, identify and estimate cards, keep your vault, run Treasure Hunter and member marketplaces, and support membership. Photos you scan are processed so the app can identify and estimate the item.
Who can see what
Your vault is private by default. Items you put on the Store or Trading Floor, and Treasure Hunter matches you opt into, are visible to other members as needed to complete that feature. Other members do not see your phone number or email.
Who we share it with
Service providers that host the database, deliver sign-in codes, run card-recognition and estimate models, and process membership payments (Stripe). They process data only to provide that service and are not permitted to use it for their own marketing.
How it is stored
Your information is held in a private, access-controlled database and is encrypted in transit between your device and our servers.
Deleting your account
You can request deletion from the account deletion page, with or without the app installed. Deletion removes your account, sign-in identifier, vault items, hunts, listings and messages tied to you. Database backups roll off on their own within about 30 days.
Children
The Hobby Treasury is meant for adults who buy, sell and grade collectibles. It is not directed at children under 13, and we do not knowingly collect information from them.
