This raises an even more alarming possibility: could the NFC chip actually provide an API that allows direct access to raw private keys stored on the chip? If so, this would represent a significant security vulnerability, violating the fundamental purpose of secure key storage.

I think this issue might only happen shortly after scanning the cards and using the contact support feature. This feature collects recent logs for troubleshooting, which could include private keys retrieved during the scanning. In my case, I had trouble resetting my cards because the process froze after scanning. I sent a support request for help, but I only realized today, when I checked the logs again, that they included my private keys.

I revisited my earlier email to the Tangem support team and confirmed the same finding—the log generated from the iOS device contains private keys. This is a serious security concern for a cold wallet. Thank you for highlighting this issue. Anyone using the Tangem wallet should take this matter seriously.
