I never thought of it like that I guess I consider myself a trustworthy person. Deleting data right away is in my best interest at this point because it keeps my hosting down. Less datase usage and less AWS usage. I could put up a privacy policy but I doubt that would convince everybody.

I hate to say it, but I'd try to find a new domain if possible. With domain hacks like this, They feel a bit dated, but worse, I never remember where the splits are.

Sec.ret.ly? Se.cret.ly? S.ecret.ly?

Also, how big is the use case? I don't think one load URLs are something I'd ever really want. What if they accidentily closed it?

And it doesn't prevent sharing, since they could just save it and re-upload.. Basically, either I trust them, or I don't. I don't see where a one-use URL helps.

The red (such as in "Send a private...") is hard to see. Needs more contrast. Same with the footer text. Use this to check for compliance: http://snook.ca/technical/colour_contrast/colour.html
