Proof + refund policy (plain language)

We try to make it obvious what you’re buying, and keep the risk low.

  • Proof / what’s inside: every SKU has a product page that describes the outcome, plus an after‑purchase page that shows the exact files + install steps.
  • Delivery: after Stripe checkout, you get a download page link. No account required.
  • Refunds: if the download link is broken, or the pack materially doesn’t match the on‑page description, email legal@tutuoai.com within 7 days for a full refund.

(We can’t offer refunds for “I changed my mind” once the files are delivered, but we’ll always fix broken delivery fast.)
