We use no analytics or advertising frameworks, and never will.
If you contact the developer for support, your e-mail address will be
stored so we can get back to you. If you would like us to delete your
e-mail address, please let us know at firstname.lastname@example.org.
(I keep writing "we" but, honestly, I'm just one guy)
tl;dr: Snap.Net does not collect or store any data.
Except when you literally e-mail me first, I can't think of any way to get back to you otherwise.
