Contact
One address, read by a person: info@dice-app.com. There is no contact form, because a form would only email the same address with more steps.
What is worth writing about
Something broken. If a roller misbehaves, a number looks wrong, or a page falls apart on your phone, tell me which page and which browser and I will go and look.
A rules correction. The game pages cover variants that different groups play differently, and I would rather have it right than have it settled. If your table plays a scoring rule another way and you can point to where it comes from, send it.
A die or a game that is missing. If you need something the site does not roll yet, say what it is and what you use it for.
What to expect
A reply within a few days for anything that needs one. This is a small site run by one person, so there is no support queue and no ticket number.
Two things that will not get a reply: link building offers and guest post pitches. Please do not send them.
For what the site collects and stores, see the privacy page. For who built it and why, the about page covers it.
