Privacy Policy

My Card Wizard identifies sports cards from photos, prices them from completed eBay sales, and helps you list them. This policy explains what we collect, why, who we share it with, and how to get it deleted.

It is written in plain language and describes how the service actually works. It is not a substitute for legal advice.

Account information: the email address you sign up with. Authentication is handled by Supabase; we do not store your password.

Card photos you upload, and the information generated from them — player, year, set, parallel, card number, condition, estimated value, and the comparable sales behind that estimate.

Workspace information: the batches you create, draft/ready status, your price and title edits, and any sale price you choose to record.

eBay connection: if you connect an eBay account, we store the access and refresh tokens eBay issues, encrypted, so the app can create listings on your behalf. We never see or store your eBay password.

Basic operational logs, such as errors and request timing, used to keep the service running.

We do not collect payment card numbers. We do not buy or ingest personal data about other people, and we do not store personal data about eBay users other than you.

Card photos are meant to contain cards. Please do not upload images containing personal documents or other sensitive information.

To identify your cards, price them, show you your inventory, and — when you ask — create eBay listings.

To improve pricing accuracy. If you record what a card actually sold for, we use that figure to calibrate future price estimates for similar cards in your account.

To operate, secure, and debug the service.

We do not sell your data, and we do not use your card photos to advertise to you.

Supabase — hosts the database, file storage, and login for the app.

Anthropic — receives your card photo to read the printed details from it. Cards are read one at a time and are not used to train models.

CardSight — a card catalog and pricing service used to match your card and retrieve comparable sales.

eBay — receives listing details when you choose to publish a listing, and provides pricing and sold-comparable data.

Sold-comparable data providers — receive the card description (for example, "2019-20 Panini Prizm Ja Morant") to look up completed sales. They do not receive your identity.

We may also disclose information if required by law.

Your inventory, photos, and workspace stay in your account until you delete them or delete your account.

Disconnecting eBay removes the stored eBay tokens for your account.

You can delete individual cards from your inventory at any time from within the app.

You can disconnect your eBay account at any time, which removes the stored tokens.

You can request deletion of your account and everything in it. Contact us from the account you want deleted and we will remove it.

Traffic is served over HTTPS. eBay tokens are encrypted before being stored. Database access is restricted to the application, and each account can only read its own inventory.

No service can promise perfect security, but if we ever become aware of a breach affecting your data, we will tell you.

My Card Wizard is not intended for children under 13, and we do not knowingly collect their information.

We may update this policy as the app changes. If a change is material, we will make a reasonable effort to let users know. The date below shows the current version.
