Data Privacy Statement

The English version is only included for your convenience. In questions of doubt the German version should prevail.

Scope of application

This data privacy declaration is intended to inform the users of this website about the type, scope and purpose of the collection and use of personal data by the website operator onoff Aktiengesellschaft in accordance with the Federal Data Privacy Act and the Telemedia Act.

The website operator takes your data privacy very seriously and treats your personal data confidentially and in accordance with legal regulations. Keep in mind that data transmission over the Internet can be subject to security vulnerabilities. Complete privacy against access by third parties is not possible.

Access data

The website operator or page provider collects data about access to the page and saves it as "server log files". The following data is logged in this way:

  • Visited Website
  • Time at time of access
  • Amount of data sent in bytes
  • Source/reference from which you accessed the page
  • Browser used
  • Operating system used
  • IP address used

The data collected is used solely for statistical evaluations and to improve the website. However, the website operator reserves the right to subsequently check the server log files if there are concrete indications of illegal use. The server log files are deleted after 180 days.


This website uses cookies. These are small text files that are stored on your mobile device. Your browser accesses these files. The use of cookies increases the user-friendliness and security of this website.

Common browsers offer the setting option not to accept cookies. Note: There is no guarantee that you will be able to access all functions of this website without restrictions if you make the appropriate settings.

Handling of personal data

The website operator only collects, uses and passes on your personal data if this is permitted by law or if you consent to the collection of data.

Personal information is any information that is used to identify you and which can be traced back to you, such as your name, e-mail address and telephone number.

Handling of contact data

If you contact the website operator through the contact options offered, your details will be stored so that they can be used to process and respond to your enquiry. This data will not be passed on to third parties without your consent.

Dealing with comments and contributions

If you leave a contribution or comment on this website, your IP address will be saved. This serves the security of the website operator: If your text violates the law, he wants to be able to trace your identity.

Season tickets

You have the possibility to subscribe to the entire website as well as follow-up comments on your contribution. You will receive an e-mail to confirm your e-mail address. No other data is collected apart from this. The stored data will not be passed on to third parties. You can unsubscribe at any time.

Rights of the user: Information, correction and deletion

Upon your request, you as a user will receive free information about which personal data about you has been stored. Unless your request conflicts with a legal obligation to store data (e.g. data retention), you have a right to have incorrect data corrected and your personal data blocked or deleted.
