The request for consent that Google sends to its users to connect its multiple services "could constitute a misleading and aggressive commercial practice," the watchdog said.
This "incomplete and misleading" information supplied to users fails to clarify the impact their consent may have on the use of their personal data, the antitrust authority, which is in charge of overseeing consumer rights, added.
Google offers a wide range of online tools, including video platform YouTube, email service Gmail and Maps.
The antitrust body said Google presented its request for users' consent in a way that could limit their freedom of choice, by inducing them to agree to a combined usage of personal data by different Google services.
"We will analyze the details of this case and will work cooperatively with the authority," a Google spokesperson said in a statement.
Under Italian legislation companies found in breach of consumer rights rules face fines ranging from 5,000 euros ($5,437) to 10 million euros.
