Questions about your account, a butterfly that is behaving strangely, or a request to see or delete your data. All of it comes to the same place.
What happens to it
Your message is sent to our inbox and kept here as well, so that a failure at the mail provider cannot lose it. It carries the name and address you type below; if you are signed in it also carries which account you are signed in as, and that is the only part of it we can be sure of. A one-way fingerprint of your address is stored beside it, so that the form cannot be flooded from one place.
Response time
Usually within a few days. Requests about your own data are answered within thirty days at the latest, as the law requires.
