The fields
Name, email, city, topic, and the message. That is the whole note, and it is what the reply uses.
Privacy
What the form keeps.
Why
The note is how the guide replies. The city decides which hall the answer is about. The topic decides whether it is a review, a hall, directions, or support.
How long
The note stays until the reply is sent, and a short while after, in case you write again. It is not sold and it is not added to an advertising list.
Taking it off
Write [email protected] and say which email to delete. The guide has no published street address.
