Yes, in most cases. We offer a 30-day satisfaction guarantee on course purchases and first-time subscriptions, provided you haven't consumed more than 5% of the course content (for individual course purchases) or more than 5% of the content of any individual course on the platform (for subscriptions). If you're not happy, just email us at academy[at]lauromueller.com within 30 days of your purchase with your order details and we'll sort it out.
Note that this voluntary guarantee is on top of, not instead of, any statutory rights you may have under EU or German consumer law.
