DuD-Poll: Privacy-preserving Poll Tool

Unfortunately, it is currently not possible to create new surveys. However, existing surveys can still be filled out.

The background to this is that we have received information that our voting tool does not meet the accessibility requirements. Initial analyses have shown that the deficiencies cannot be trivially remedied. As soon as we have a new version that has implemented the necessary requirements in a meaningful way, we will release our voting tool again. Unfortunately, it is not yet possible to predict when this will be.
