johndoe55667788 I think it's likely that Google did associate the IMEI to your purchase identity (I had the same concerns), but my understanding is that the IMEI isn't typically available to apps, including even the sandboxed Play components.
From the FAQ:
Can apps access hardware identifiers?
As of Android 10, apps cannot obtain permission to access non-resettable hardware identifiers such as the serial number, MAC addresses, IMEIs/MEIDs, SIM card serial numbers and subscriber IDs. Only privileged apps included in the base system with READ_PRIVILEGED_PHONE_STATE whitelisted can access these hardware identifiers.
It's also worth keeping in mind that folks buy, sell and trade cell phones everyday. Just because you bought it today doesn't mean you'll be the one using it next month. I think that what you actually do with it once in-hand is more likely to compromise your privacy.
