1. Sign in to the eBay account you authorised.
  2. Open My eBay › Account Settings › Sign in and Security › Third-party app access.
  3. Find SellerHint and revoke its access.

This stops access under that authorisation. It does not erase records already downloaded into SellerHint or cancel an App Store subscription. Reauthorise in SellerHint if you later want to reconnect.
