These terms apply to all services provided by Martijn Vincken Music, a sole proprietorship registered in the Netherlands (KVK 90286995, BTW NL004804245B06), operating under the trade name MSTR. (“we”, “us”).
We provide professional audio mastering services via this online platform. Two packages are available:
Both packages include: professional lossless master, upfront written feedback, one (1) free revision if requested, and metadata embedding. Additional release platforms are charged at €20 ex VAT per platform beyond the first.
An order is placed when you complete the booking form and payment is confirmed by our payment provider (Mollie). All prices are exclusive of 21% Dutch VAT (btw). The total amount including VAT is shown at checkout.
Payment must be completed before file upload is enabled. Accepted methods: iDEAL, credit card, debit card, Wero, and PayPal — all via Mollie. Your payment details are handled exclusively by Mollie and are never stored by us.
Before mastering begins, you will receive written feedback within two (2) business days of mix receipt. You may then choose to proceed or to update your mix. One (1) revision of the finished master is included free of charge. Additional revisions beyond the included one may be quoted separately.
Estimated session and delivery dates shown during booking are indicative. While we aim to honour them, they are not contractually binding. The finished master is made available via your account dashboard as a signed download link.
By booking the Basic · Content Use package, you grant Martijn Vincken Music a non-exclusive, royalty-free, worldwide licence to use excerpts of the finished master in promotional material (social media, portfolio, website, showreel). This licence does not transfer ownership of the master recording, which remains yours.
Under Dutch consumer law (Wet OHP / BW), you have a 14-day right of withdrawal for distance contracts. However, by explicitly requesting that work begins before the 14-day period expires (which you do by uploading your mix), you acknowledge and agree that the right of withdrawal lapses once the mastering service has been fully performed.
If work has not yet started, cancellation requests can be sent to martijnvinckenmusic@gmail.com.
Refunds are handled on a case-by-case basis. If you are dissatisfied, please contact us before disputing with your bank or payment provider. We do not issue refunds after the master has been delivered, except where there is a demonstrable technical error on our part.
The mastered recording is your intellectual property. We retain no ownership over your music. All files you upload are treated as confidential and are not shared with third parties beyond what is technically necessary to provide the service (cloud storage via Supabase).
Our total liability for any claim arising out of or relating to these terms or the services is limited to the amount you paid for the specific order giving rise to the claim. We are not liable for indirect, incidental, or consequential damages.
We are not liable for data loss caused by circumstances beyond our control (e.g. third-party storage outages). We strongly recommend you keep your original mix files.
These terms are governed by Dutch law. Disputes that cannot be resolved amicably will be submitted to the competent court in the district where Martijn Vincken Music is registered, unless mandatory consumer law provisions require otherwise.
We may update these terms from time to time. The date at the top of this page reflects the most recent revision. Continued use of the service after an update constitutes acceptance of the revised terms.
