Virgin Media has changed the terms and conditions for users of the Wi-Fi service it has begun rolling out across London's tube network in response to complaints from privacy campaigners.
Originally, Virgin had told users they had to agree to have their emails and other communications monitored in order to use the system.
But the company has now altered its terms and conditions to assuage users' privacy concerns.
“We are not monitoring how individuals use our Wi-Fi service and have clarified our T&Cs to make this clear,” a company representative told V3.
Virgin added that it had never intended to monitor the content of users' emails, tweets or instant messages, but had to monitor the service to ensure it was not being used illegally.
“We block illegal or harmful content in line with our legal and regulatory obligations,” the representative added.
Privacy campaigners such as Nick Pickles from Big Brother Watch had warned that Virgin's previous terms could have let it snoop on users with impunity. As such he welcomed the changes made by the firm.
"The public should be able to use Wi-Fi services without fear of their internet use and emails being monitored, especially for marketing purposes," he told V3.
"Clearly such broad terms and conditions were a cause for concern and I'm pleased Virgin have moved quickly to address this serious privacy issue."
The first stations to offer the underground Wi-Fi service went live last week. Virgin plans to have around 80 stations live in time for the Olympics, with more planned to go live later this year.
