Internet usage data / cookies

Surfing on the Internet generates a large amount of data. Normally, however, Deutsche Telekom only saves the data that is relevant for billing. We delete this data after three months at most.

What Internet data do we store?

If you use a flat rate, no billing data is stored, only general traffic data such as usage times. The data is stored for up to seven days after the end of the connection. For tariffs that have a data volume limit, the data volume used, the usage times and your IP address are assigned to your contract data. An exception exists if misuse of a service or system needs to be uncovered. We do not store your surfing behavior.

How do we use Internet data?

Your data provides information about when the contractually agreed inclusive volume is used up, if that is part of your contract. The IP address is only stored in order to detect misuse, such as spam, viruses or "worms". In addition, we can detect and eliminate faults in our network at an early stage. For this purpose, we store your IP address for seven days from the end of the connection.

Is data passed on to third parties?

In exceptional cases regulated by law, we are obliged to hand over traffic data to authorities for the purpose of criminal prosecution, see e.g. §§170ff TKG.

Crazy facts - Internet usage data

Crazy facts

Every day, Deutsche Telekom's network faces an armada of more than 50 million devices.

And our network welcomes all of these many, many devices. It embraces them, assigns them to their proper places, and makes the right connections when Mike wants to call Sally, and not the garbage collectors. Imagine what would happen if communications were based on the principle of random chance.
