How do I delete my account or unbind my CarPal device to sell it to someone else?
To prepare your TOPDON CarPal for a new owner, you should unbind the device from your account so your friend can register it. While the manual does not provide a specific "delete account" button, it details how to manage device associations.
Follow these steps to remove the device from your profile:
Once the device is removed from your account, your friend can download the app and follow the "Register & Log In" steps to create their own account and activate the VCI. If you specifically need to delete your entire TOPDON cloud account, you may need to contact TOPDON support directly at support@topdon.com as this function is typically handled through their customer service portal.
Note: Ensure you have also deleted any saved vehicle makes in the same menu if you wish to clear your diagnostic history before the transfer.
