1. No purchases through this preview

The current vonka.si website introduces Vonka. It does not accept orders or payments, open subscriptions or create product accounts. Browsing it does not place an order, so there is no website purchase or renewal to cancel.

Product pricing, purchase terms, cancellation procedures and refund information will be provided before Vonka opens for purchases. This page does not set a refund window, cancellation fee or subscription period for a future service.

2. A separate purchase or agreement

If your enquiry concerns an existing purchase or separately arranged service, review the receipt, order confirmation and terms supplied with that agreement. Those terms and applicable law determine the relevant rights and process; this preview notice does not replace them.

If you are unsure which agreement or product a charge relates to, contact support@bullbillion.com and identify the product and seller shown on your receipt. A JAU purchase is separate from Vonka and follows the information supplied by JAU.

3. Information to include

To help us identify an enquiry, include the product name, the contact email used for the purchase, an order or transaction reference if you have one, and a brief description of the issue. For a disputed charge, include its date and amount. Do not send passwords, access tokens or full payment-card details.

4. Cancellation, refunds and privacy requests

A request to cancel a service, a request for a refund and a request to delete information are different. Say which outcome you are asking for. One does not necessarily complete the others under a separate agreement.

For a request about personal information handled by this website, use the process on GDPR and Privacy Rights. Nothing on this page removes a mandatory cancellation right, refund entitlement or other remedy under applicable law.

5. Contact and changes

For questions about this website or these notices, email support@bullbillion.com or write to BullBillion Inc., 2261 Market Street, San Francisco, CA 94114, US. Identify Vonka and give us a way to respond. Please do not send passwords, access tokens or full payment-card details.

We may update these notices when this website or our practices change. The date above identifies this version. Product terms and privacy information will be provided before accounts, purchases or hosted services become available.
