 The AI chatbot is used as an assistant for frequent and recurring questions (concerning the first increment of the one-off energy payment) on the website.

Storage of the chat record:

The chat record is stored for forwarding to the relevant department and/or for continuous improvement of the service quality beyond the duration of the conversation. The chatbot solution uses a software program that uses an algorithm based on artificial intelligence and that continuously improves itself.

The conversations are generally given a randomly generated pseudonym that cannot be attributed to specific chatbot users and thus ensures their anonymity.
The stored data contain the text and/or attachments, the date the messages were written, and the intents/responses that they prompted. The duration and time of the communication are stored in anonymized form for statistical purposes - in particular, in order to optimize the service.
