From a data privacy point of view I would very much appreciate if you added a prominent "delete upload" button to the result page.

"We do not save the uploaded image." from the take-this-seriously? popup.

[rndmind]

Yes a "delete" button would nice.

We do not store any photo on the server, so no worries!

[tlrobinson]

Well, you could still add a delete button to make people feel better (I'm only half joking)

And as a potential user I'm only half-insulted.

But seriously, what purpose would it serve over a promise in TOS? A normal user will trust both (except the button would be bullshitting them). A privacy-obsessed one will trust neither.

You could make a delete button which merely opens a popup to explain that they do not save it in the first place. That way if they're looking for a delete button, they'll find it, but it will give them the right information.
