Privacy Policy
Last updated September 21, 2026. This page is for the Sleevehouse / Cardanize inventory app. It is not legal advice.
Who we are
Sleevehouse organizes, stores, catalogs, and helps sell or return sports cards for collectors. The first client collection is operated as a consignment test. The app is used by staff and, later, by invited collection owners.
What we collect
- Card catalog data you or staff enter (player, year, set, number, condition, location, notes, status).
- Photos of card fronts and backs that you upload from a computer, scanner, or camera.
- Collection name and file numbers (for example JC-B5-000001).
- Optional account email or Google sign-in when invites are enabled.
- Technical logs from hosting (Netlify) and the database (Firebase), such as approximate region and device type.
What we do not put in the public website files
SportsCardsPro and CardSight API keys stay in Settings and the private cloud project. They are not published in the downloadable site files.
How we use data
- To inventory, sleeve, store, value, grade, sell, trade, or return cards as requested.
- To show a collection owner their own cards only, after an invite.
- To look up identity and market values through vendors we use (currently CardSight and optionally SportsCardsPro / PriceCharting).
- To back up and sync the same collection across staff devices.
Vendors that may see card data
- Google Firebase (database, photo storage, authentication).
- Netlify (website hosting).
- CardSight AI when you use Match from photo (the front image and resulting catalog IDs / comps).
- SportsCardsPro / PriceCharting when you look up or lock a catalog ID.
Those companies process data under their own policies. We send only what is needed for that feature.
Sharing
We do not sell personal data. A collection owner can be shown only their collection. Staff who operate Sleevehouse can see collections they are assigned to. We may share data if required by law, or with a processor we hire to host or repair the app.
Retention
Card records and photos stay until the collection is returned, deleted at the owner’s request, or we no longer need them to run the service and keep tax / consignment records.
Your choices
Staff can export a JSON or CSV backup from Settings. Collection owners can ask us to correct or delete their collection. If you signed in with Google or email, you can ask us to remove that login from the collection.
Children
The staff app is for operators. We do not intend the public download to collect data from children under 13.
Security
Access is limited by Firebase rules and, when enabled, collection invites. No method is perfect. Do not forward invite links. Do not screenshot API keys.
