Terms of Service

By accessing TrumpetMastery.com, you understand and agree to the terms of service listed below.


When you join the Trumpet Mastery™ Course program on TrumpetMastery.com, you understand that the cost of membership is $249.00 USD per year, and renews on the same month and day each year unless cancelled at least 3 business days before your payment is processed.

Should a payment be attempted by Stripe, Inc. and it fails, we will NOT attempt a second withdrawal and you will have to start a new membership application via our API Stripe form. If Stripe, Inc. attempts a withdrawal on your renewal date and the payment fails, your account will immediately be suspended until payment is resolved. After 30 days, Cassus Digital LLC reserves the right to delete your account and all data associated therein.

Membership to the Trumpet Mastery™ Course provides you, the customer, access to a Dashboard which is accessible to active, paying members of TrumpetMastery.com. You will lose access if your payment fails.

If you have issues accessing your account or require assistance, please contact Paul Cassarly at contact@cassusdigital.com, or use the Contact form provided here to send a message for any questions or concerns you may have.
