Terms of Sale

*Estimated performance of promotions are updated from time to time based on current promotion performance, your promotion performance may vary. Impression rates vary over time, and subscription rates are affected by the perceived value of your podcast.

All sales are final. No refunds.

The price and quantity of promotions sold may change from time to time.

Castro may make minor changes to your promotion with regard to art and copy to fix mistakes or improve performance of your ad.

Once you purchase a promotion, it must be approved by Castro before it goes live, which typically occurs within 1 business day when inventory is available. Castro reserves the right to reject a promotion for any reason, such as (but not limited to) billing issues, quality concerns, or content.

Promotional text and images must be appropriate for a general audience of all ages.

If your promotion is not accepted, your payment will be refunded if possible, with the refund pro-rated if the ad has already run for a portion of its purchased duration.

Please contact with any questions.
