Storing users' data

[8adam95]

Hi, we want to integrate with Spotify API to develop a feature which would allow our users to discover their personality traits based on the music they listen to. For this reason we would have to store Spotify's users' data on our side for all of the calculations. We have read your terms and conditions, but it's still quite unclear whether we're legally allowed to do that (considering users give us all of the necessary privileges)?

Also we're aware of the fact that if users opt-out of the integration, we would have to delete all of the user's Spotify data from our side.

Best regards,

Adam
