Your account

We store your name, email address, profile image when provided, and account identifiers to sign you in and save your talent cards and pack history. Email accounts use a hashed password. Google sign-in shares your basic profile and verified email address with us; we do not request access to Gmail, Drive, or your contacts. Authentication records can include provider tokens, session identifiers, IP addresses, and browser information.

How data is used and stored

We use account data to authenticate you, operate your collection, enforce the daily pack limit, and protect the service against abuse. Vercel hosts the application and Neon stores its PostgreSQL data. Resend sends account emails when configured. Stripe processes payments if you buy a future paid product; pack opening remains free. Cloudflare R2 may store public media. Google AdSense may show ads on public pages when a publisher id is configured. These providers process data to run the service. Google handles Google authentication. We do not sell your account information or use Google account data for advertising.

Card trading

When you list a card, other signed-in players can see that card and your account display name as its agent. Trade offers show the two cards and both agents’ display names to the participants. Your email address and unlisted collection are not included in the transfer market. We store offers and card ownership to complete swaps and show deal history. You can unlist cards and cancel pending offers you sent; accepted swaps are final.

Cookies and local storage

Authentication cookies keep you signed in. Your browser also stores interface preferences and your watchlist locally. Signing out ends your session; clearing browser storage removes locally saved preferences.

Retention and your choices

Account and collection data remain stored while your account exists. To request access, correction, or deletion of your account and associated cards, email us from your account address. We may need to verify your identity before fulfilling a request. Operational logs and provider backups can remain until their retention periods expire. You can also remove Tech Transfers access in your Google account settings; doing so does not itself delete your Tech Transfers collection.

Public talent profiles

Talent profiles are compiled from public sources, with source links and editorial ratings. They are separate from player accounts. Contact us to report inaccurate profile information or request a correction.
