Location data is generated whenever your mobile phone connects to a mobile network cell or when your router connects to the Internet. An antenna is located in one corner of the mobile network cell and establishes the actual connection. Therefore, the location of the transmitter is known, but your exact location cannot be determined, because it is not possible to locate a mobile phone precisely within a cell.
What location data do we collect?
We use your location data to establish a connection between the wireless network and your mobile phone. Without this location data, cellular links would not even be possible. This data is only saved in special cases (for example, if you use an old, location-based contract). If you have a flat rate, like most of our customers, the data is deleted after seven days at the latest.
The location of a hotspot can be identified precisely through an IP address, for example, when data transmission takes place via WiFi. This location data is temporary and is saved for a maximum of seven days before it is deleted.
What do we do with your location data?
We use location data to establish a connection to your device, such as your mobile phone or router. This data is also anonymized and aggregated for use in analyses and to prevent misuse and disruptions. This data is also highly beneficial for many other services. Information about the number of people present at a certain location, for example, helps bus and train operators optimize their capacity utilization. This enables these partner companies to better inform you, the customer, which in turn lets you make more informed decisions. Motionlogic GmbH, a Deutsche Telekom subsidiary, specializes in such analyses and works together with companies that want to optimize their services. As mentioned above, the data is anonymized and cannot be traced back to your person or your device. Moreover, you can object to this type of data use at any time.
How is this data passed on to third parties?
All data that we use for analysis purposes is anonymized. It may, however, be used for analyses by our subsidiary, Motionlogic GmbH. Movement profiles cannot be traced to a specific individual. You can object to this use at any time. If a court orders it, we might have to disclose location data.
