Do my visitors see anything?
No. The check runs between your server and ours after the form is sent.
What data do you receive?
Only what you send: the text of the entry and the details sent with it, such as name and email, plus your site and page title. Read the privacy page for details.
What happens if you are down?
Your forms keep working. Entries go through unchecked until we are back.
What if I go over my plan?
Nothing breaks. Extra entries go through unchecked until your plan resets or you upgrade.
