Guidelines for using the library's messenger information service
Please be mindful of protecting your personal information. When using the messaging app, only send content that, in theory, anyone could see or read. For more confidential inquiries, please contact us in person, by phone (082155863933), or by email (bibliothek@tha.de).
We will store your cell phone number and chat history only until we have fully responded to your inquiry. After that, the data will be deleted from the library’s smartphone. We do not share your data with third parties.
We do not use WhatsApp or Threema as channels for advertising or newsletters. We only use them to respond to your inquiries.
Our cell phone number is intended solely for receiving and sending text messages via WhatsApp and Threema. We do not accept calls at this number.
If we receive spam messages or messages containing offensive content, we will delete them without comment and block the sender.
