Business and support
SDC (Sterenberg DC) provides online education and startup learning programs. For questions about a purchase, course access, or a payment, contact support@sterenbergdc.shop.
Business owner contact: sabrisan33@hotmail.com.
Products and delivery
Courses are educational digital products. The product title, description, price, and any included service are shown before checkout. Access or delivery instructions are sent to the email address provided at checkout after payment is confirmed. Premium mentorship includes the scope and scheduling agreed with the customer before fulfillment.
Payments
Payments are processed securely by Stripe. SDC does not receive or store full card numbers. Customers must provide accurate billing and contact information and must not use payment methods they are not authorized to use.
Refund and cancellation policy
Customers may request a refund within 14 calendar days of purchase by emailing support@sterenbergdc.shop with the order email and course name. Refund eligibility may depend on whether substantial one-to-one mentorship or other custom services have already been delivered. Approved refunds are returned to the original payment method. Scheduled mentorship may be cancelled or rescheduled by contacting support at least 24 hours before the appointment.
Privacy and customer data
We use customer information only to process orders, provide course access, respond to support requests, and meet legal obligations. Stripe processes payment information under its own privacy and security policies. We do not sell customer information.
Acceptable use and educational disclaimer
Course materials are for lawful educational use. Customers may not redistribute, resell, or share paid materials or access. Courses provide education and do not guarantee employment, funding, revenue, or business success. Results vary by effort, experience, market conditions, and execution.
Disputes and support
Please contact support@sterenbergdc.shop first so we can investigate billing or fulfillment issues. We respond to support requests as promptly as possible and keep records of order and support communications.
