Refund policy
We want the pack to be a low-risk purchase. Try the free Spanish preview before buying.
Seven-day guarantee
Request a refund within 7 calendar days of purchase by emailing hello@matternium.com with the receipt email and purchase date. Approved refunds return to the original payment method and revoke paid access.
Access problems
If protected playback does not work, contact support. We will first try to restore access and will refund when we cannot deliver the purchased pack.
Local rights
Nothing in this policy limits refund or cancellation rights that cannot legally be limited where you live.
