Google is keeping a secret log of all your online shopping purchases, it has emerged.
The log is compiled from receipts sent to your Gmail account, and goes back years.
It includes Amazon and eBay purchases, monthly subscriptions and songs bought on linked music accounts - along with estimated dates that the orders were fulfilled.
You can access the Purchases webpage here if you have a Gmail account.
Google does not use this information to create personalised adverts, according to CNBC , which uncovered the logs.
However, Google only announced it would stop using Gmail account data to create personalised adverts in 2017.
"To help you easily view and keep track of your purchases, bookings and subscriptions in one place, we've created a private destination that can only be seen by you," a Google spokesperson said.
"You can delete this information at any time.
"We don't use any information from your Gmail messages to serve you ads, and that includes the email receipts and confirmations shown on the Purchase page."
CNBC notes that deleting this information from the Purchases webpage is not easy, because each item must be deleted individually.
There is also no way to delete the log from Purchases without also deleting the receipt from your Gmail account.
The news comes only a week after Google CEO Sundar Pichai wrote in the New York Timesthat "privacy cannot be a luxury good."
The firm has recently been trying to be more transparent about what data it is collecting, how it is doing this and how the data can be deleted.
