Spotify users, including a number of high-profile online figures, are leaving the music streaming service over changes in its terms and conditions that give the app more access to users smartphone data.

The apps for both iOS and Android now ask for permission to access pictures, phone contacts and sensor data, as well as permission to view users social media activity. According to Spotify, the changes will help tailor improved user experience.”

However, many users have taken to Twitter to register their displeasure at the changes, including creator of Minecraft Markus Persson, who tweeted to his 2.4m followers that he had cancelled his account over the revised terms and conditions.

Among the changes in the revised terms and conditions is the warning that it is up to the user to ensure that everyone listed in their contacts list is happy for their phone number to be shared with the music platform.

“We are constantly innovating and evolving our service to deliver the best possible experience for our users,” said Candice Katz, user communications manager at Spotify, in a blog post about the new terms. “The privacy and security of our customers data is – and will remain – Spotifys highest priority. We will always ask for individual permission or clearly inform you of the ability to opt out from sharing location, photos, voice and contacts.”
