The legal basis for this is Article 6(1)(b) GDPR. Our payment service provider for processing credit card payments is PAYONE GmbH, Lyoner Strasse 9, 60528 Frankfurt am Main, Germany.

Enquiry regarding bookings
If you use the contact form / chatbot to ask questions regarding a booking, our system uses the details in your customer account, including the contact details it contains, to process your enquiry and in the event of follow-up questions. 

Offers relating to similar products or services
We take steps in order to maintain customer relations with you and to provide you with information and offers which we think will correspond to your travel preferences and interests.

Newsletter registration
If you use your customer account to register for a newsletter, our system uses the relevant data in your account.
When you register for a newsletter, we also store the IP address assigned by the Internet Service Provider (ISP) to your end-user device used at the time of registration, as well as the date and time of registration. The collection of this data is necessary in order to trace (possible) subsequent misuse of the e-mail address of the person concerned and it therefore serves our legal protection.

Participating in competitions
When we run competitions, we collect data for managing the process. The precise details, i.e. what data is collected and for what purpose, are available on the web page of the relevant competition.

Virtual chat assistants
On the virtual assistant (also called chatbot) DB Smile is used. The chatbot serves as an information and customer contact channel for questions relating to DB passenger transport. Communication with the chatbox is easy, and customers can obtain information and receive answers to their questions quickly. DB Smile responds to a large number of requests automatically with the help of artificial intelligence and keyword recognition, offers suggestions and assistance for communication with the chatbot or refers users to other customer service channels (hotline or contact form). At this stage, the chatbox is unable to answer complex or individual customer inquiries. If a request cannot be answered automatically by our bot, you have the option of chatting in real time with a staff member.

At present no contract-related customer inquiries are processed or resolved automatically or via live chat. Anyone who has questions of this type can continue to contact us via phone or e-mail. Users should therefore not provide any personal information when interacting with the chatbot.

Your inquiries are stored in the chatbot for a maximum of 30 days in order to train the chatbot and optimise response recognition and accuracy. The chatbot can thus be continuously developed in terms of content and functionality. No personal data is analysed. Usage data such as chat duration, timestamp of messages, number of messages or operating system used are only stored for statistical purposes. We process user information only in order to handle their queries and for internal purposes, e.g. managing and improving processes related to our business and services (Art. 6(1)(b) GDPR). 

Booking a digital ticket after visiting a partner website (as part of affiliate marketing activities)
If you make a booking on an external partner website after clicking a DB affiliate advertisement, the business partner's cookies on that website are read. The relevant cookies have a lifetime of 30 days. This step is necessary for paying the business partner for the booking you make. We work with the Awin network for the purposes of affiliate marketing. 

We only store your data for as long as necessary so we can achieve the purpose for which it was collected (e.g. in the context of a contractual relationship) or insofar as permitted by law. Thus, in the context of a contractual relationship, we store your data until final completion of the contract. Thereafter, the data will be stored for the statutory storage period.
