Spotify wants to cozy up to you and find out more about what you do, where you go, who your contacts are. Does that make you uncomfortable?
3.4 Location and sensor information Depending on the type of device that you use to interact with the Service and your settings, we may also collect information about your location based on, for example, your phone’s GPS location or other forms of locating mobile devices (e.g., Bluetooth). We may also collect sensor data (e.g., data about the speed of your movements, such as whether you are running, walking, or in transit).
There are a few reasons why Spotify might want deeper access to your device, and it’s not just advertising-related. The location and sensor data access could signify plans to develop more features similar to Running, which takes your phone’s motion into account to determine your pace so it can match songs with the same beats per minute. It’s not so clear why Spotify would need access to your contacts and photos, but a company spokesperson told Forbes that the data “helps us to tailor improved experiences to our users, and build new and personalized products for the future.”
Spotify also pointed to its new (and beloved) Discover Weekly personalized playlist as an example of the kinds of features it plans to add down the line.
