A name and an email address on the form, plus anything you decide to type in the message field. There is no sign-up and no profile page, so this is the entire record we can hold.
Into one mailbox on the hosting server, where a person reads it. The page itself loads no external fonts, no scripts and no pixels, so browsing it leaves no trace outside ordinary server logs.
Messages are kept for a year after the last reply and then deleted. If you would rather not wait, ask and it goes the same day.
Copy, correction or deletion — one message through the same form. No justification is needed for any of the three.
When Roomeet opens, this page will be rewritten before any account or order becomes possible, so nothing is collected by surprise later.
