This is quite troubling and enlightening to the point that I'll have to start redirecting my purchase receipts to a non gmail account.

Are there any other 'hidden' urls to expose what other data Google is siphoning off our private transactions or conversations for that matter?

I've had all controls under activity disable a long time and periodically check to make sure they stay that way.

This one crosses the line! To the point that the only way I can get rid of the older records is to delete the purchase receipts entirely.

This link needs a thread of its own
