What is an SMS Static Site?

An SMS static site is a website you author to by sending text
messages to a special number. Words and photos you send are added to
the top of your page.

User Guide

 2. Your message is added to the top of your site.
 3. A confirmation message is sent back to you with a link to your
    site.

Terms of Service

This was a fun weekend project. No warranty expressed or implied.
Service may be discontinued at any time without notice. Service may
be refused to anyone for any reason or for no reason.

Acceptable Use Policy

I'm all about the free exchange of ideas and open discourse but I
don't have an army of lawyers and if I did I probably wouldn't want
to pay them to defend some rando's Internet nonsense. If your site
causes trouble or looks like it's going to, I'll probably block and
drop it. Otherwise, I expect we'll be cool.

Privacy Policy

I don't try to collect or store any of your private information other
than what's necessary to provide this service. I don't plan to do
anything creepy with what I do collect. I use Twilio for phone stuff.
They have their own privacy statement.
