8. To what threats we want to draw your attention?

The Facebook, Inc., within the carried out activity, transfers your personal data outside the European Economic Area (EEA). Therefore running the page on Facebook we do not have full control of what identification information the service owner holds and how he processes it. This results from the fact that in the United States there is a lower level of personal data protection than in the European Union. The GPRD is not effective in the USA and it is not certain that your rights will be respected. Who has what impact on your privacy?

1. Using the ZTM Info page on Facebook you must be aware that you do not have a full guarantee to obtain access to your personal data, to rectify it or to erase it.

2. You have limited possibilities to sue before United States courts your rights in the field of personal data protection. The legislation there does not guarantee European Union citizens the right for effective legal protection before the court and a fair trial (Art. 47 of the Charter of Fundamental Rights of the European Union).

What can you do?

If you do not agree to transfer your personal data processed via the ZTM Info page on Facebook, you can give up following our Facebook page and stop starting relationships with us via its use, including contacts via Messenger, or placing comments, using the likes.
