What to contact us about
Billing, purchases & refunds
Digital purchases (guides and Gold Stars) are delivered immediately and are non-refundable — see the Terms. If something went wrong with a charge or you were billed in error, email us first: we can resolve genuine billing problems directly, and filing a chargeback on content you accessed will revoke it and suspend purchasing on your account while we review.
Your privacy & data
You can download or permanently delete everything we store about you from your Account page (“Download my data” and “Delete my account”). For any other privacy request or question, email us and see the Privacy Policy.
Copyright (DMCA)
To report infringing content or file a counter-notice, follow the process on our DMCA & Copyright Policy page (notices must go to our designated agent to be effective).
Reporting content or abuse
Community guides and user content are governed by our Content Policy. Use the in-app report button on a guide or in a party game, or email us with a link and a short description.
Cosmetics, crates & virtual currency
Crates contain randomized cosmetic items with no cash value; full drop rates are published at Crate drop rates. Gold Star purchases aren’t available in all regions. Questions? Email us.
