What happens to what you send.
The forms ask for your name, a way to reply, and what you need. That is everything they collect.
What it is used for
Answering you, and putting together the scope and dates that come with the answer. It is not sold, shared or added to a list.
What the site stores
The site runs no analytics and sets no cookies. Whatever you tick stays in your own browser until you press Send.
Getting it back, or having it deleted
Write to the address in the footer and say so. The answer comes back the same way everything else here does: one reply, from the person who would do the work.
This page covers the website. Work on a site runs under the terms the client sets, agreed before the first flight.
