Requesting a refund for a Curiosity Stream subscription depends on the billing platform used to purchase the plan. Direct purchases made through the official Curiosity Stream website are generally non-refundable for partial subscription periods, though customer support evaluates billing errors on a case-by-case basis. Subscribers who signed up through third-party app stores—such as Apple App Store, Google Play, Amazon, or Roku—must submit their refund requests directly through those respective digital storefront customer service portals.
