Privacy
What this site collects, which is very little.
What is collected
If you send a message, the address you send it from and whatever you write in it. That is used to reply to you and nothing else.
Analytics
The site records aggregate page views so it is possible to tell whether anyone is reading it. No profiles are built and nothing is sold.
What is not collected
No accounts, no advertising identifiers, no cross-site tracking.
Your data
Ask and it is deleted. There is no process to go through; there is one person and one inbox.
