How private is your Gmail, and should you switch?
Google’s email service, Gmail, collects large amounts of data – this was recently put into stark focus for iPhone users when Gmail published its app “privacy label” – a self-declared breakdown of the data it collects and shares with advertisers as part of a new stipulation on the Apple App Store.
According to the label, those that grant the appropriate permission to the iOS Gmail app can expect Google to share information including their approximate location, user ID – an identifier used to anonymously track them – and data about the ads they have viewed online with advertisers. More data is used for analytics – in Google’s words, “to build better services” – including purchase history, location, email address, photos and search history.
