WhatLedger helps trading card collectors and sellers organize inventory, purchase lots, show results and business records in one account.

Record sales and giveaways, compare show results and estimate profitability.
Organize supporting documents and export business records for review.

Google sign-in and optional purchase imports

Sign in with Google to create or access your WhatLedger account using your basic profile and email address. Signing in does not grant access to your Gmail inbox. Gmail receipt import is a separate, optional connection.

Optional TCGplayer imports from Gmail

Connect your own Gmail account to locate TCGplayer purchase receipts, turn clear purchase details into inventory lots, and review uncertain matches. Duplicate order protection prevents the same receipt from adding inventory twice.

Gmail access is read-only. Google’s permission allows reading email messages and settings. WhatLedger uses it to find TCGplayer receipts; it cannot send, modify or delete your mail. Full email bodies are not retained. You can disconnect at any time; existing purchase records remain.

Gmail connections are currently in a limited testing rollout. Availability depends on the app’s Google OAuth approval and your account’s test access. Read the privacy policy for data use, sharing, retention and deletion details.

WhatLedger is a trading-card inventory and business-records application. It does not generate intimate imagery or use Google user data to create images.
