8. Intellectual Property Rights

The App and its original content, features, and functionality are owned by DOA and are protected by international copyright, trademark, and other intellectual property laws.

Creem handles all payment processing and ensures that your payment information is securely encrypted and not stored by DOA. All subscription charges will appear under the name of our payment partner on your bank statement.

Refunds are handled on a case-by-case basis in accordance with Creem’s payment terms and our internal review process. Approved refunds will be credited to the original payment method within 5–10 business days, depending on your bank or payment provider.

We reserve the right to decline refund requests if the service has been used extensively, abused, or if a large portion of the subscription period has already elapsed.

11. Termination

We reserve the right to terminate or suspend your account and access to the App for violations of these terms or for any other reason at our sole discretion.
