This page explains the terms that apply to services provided by ST Mastering, how we handle personal data under UK GDPR, and the key policies that affect bookings, file delivery, revisions, and data retention. If you have any questions, contact us using the contact information supplied on this website.

1) TERMS AND CONDITIONS

1.1 These Terms and Conditions apply to all services provided by ST Mastering to the Client. They override any terms proposed by the Client unless we agree otherwise in writing. The Client books ST Mastering to provide audio services and deliver the agreed work.

1.2 Assessment before booking
Every job may be assessed before we confirm a booking. We may decline a project if it is not a suitable fit.

1.3 Files and materials you provide
You confirm that you own, or have permission to use, all audio and materials you submit, and that submitting them does not breach any other agreement. You agree not to upload or send content that infringes copyright, trademark, patent, or other rights, or breaks any applicable law, or interferes with the website or services.

1.4 Children
Children under the age of 13 may not use this website. If you are over 13, you may use this website only with the consent and supervision of a parent or guardian.

1.5 Credits
If your release is mastered by ST Mastering, you may credit:
“Mastered by ST Mastering”
stmastering.co.uk
Credits should appear in an appropriate place and be consistent with other liner note information. For commercially viable releases, publishing credits may be discussed by agreement.

1.6 Revisions and changes
We aim to get it right first time, but adjustments may be required. To request a revision, please provide:
1) the exact stem or file name you supplied
2) time references in mm:ss
3) clear instructions, for example “Bass at 01:04 reduce by 30%”

We include two revision rounds for mix and mastering, with as many notes as you like in each round. Additional revision rounds are billed at £30 for up to two further sessions.

Revision requests must be made within two weeks of delivery unless we agree an extension in advance.

Repeated end user adjustments may be billable, for example:
– requesting a change, then requesting to revert close to the original
– submitting new stems or parts not included in the original project
– arrangement changes requiring manual recall and setup

1.7 Mixdown and multitrack guidelines
Following these guidelines helps avoid delays and prevents errors:
– If sending more than one song, tell us the order of the songs
– Include a rough mix in MP3 or WAV for reference
– Send stems in WAV or AIFF at the highest resolution available
– Avoid clipped or distorted exports unless intentional
– Use one folder per song, labelled “Song Title, BPM”
– Do not include unused parts
– Commit creative effects if they are part of the sound
– Remove automation from the session and include it in the audio export
– Label tracks clearly so there is no guessing

1.8 File delivery and your backups
After we deliver your completed work, you are responsible for downloading and backing up your files. We do not guarantee indefinite storage of any materials.

1.9 Data retention and archive retrieval
We may retain and or archive copies of your materials for operational purposes. If you request a re delivery after 6 months and we still have the project archived, a retrieval and handling fee may apply. Current archive retrieval fee: £20.

1.10 Disclaimer and limitation of liability
Except as expressly stated in these Terms, the website and services are provided “as is” and “as available” without representations or warranties of any kind, either express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non infringement. To the fullest extent permitted by law, ST Mastering is not liable for any indirect, incidental, consequential, special, exemplary, punitive, or other damages arising out of or relating to the website or services, even if advised of the possibility of such damage. We do not warrant that the website or services will be uninterrupted or error free, that defects will be corrected, or that the website or servers will be free of viruses or harmful components.

1.11 Governing law and jurisdiction
These Terms and any disputes or claims arising out of or in connection with them are governed by the laws of the United Kingdom, and each party consents to the exclusive jurisdiction of the Courts based in Northern Ireland.

If you purchase a subscription or credit based service, subscription pricing applies only while an active recurring payment is in place. If you cancel a subscription, any remaining credits are forfeited and services are considered rendered in full. We do not provide refunds for partial months or years.

4) COOKIES

We use cookies to improve performance and understand how visitors use the site. Some cookies are essential for the website to function. Other cookies, such as analytics cookies, help us understand which pages are used and how the site can be improved.

Where required, we will ask for consent before setting non essential cookies. You can change your cookie preferences using our cookie settings tool (if available) or your browser settings.

5) REFUNDS, CANCELLATIONS, CHARGEBACKS AND COOLING OFF

5.1 Services and refunds
All services on this website are service and time based. Unless we agree otherwise in writing, all fees are non refundable. This includes, but is not limited to, situations where work has started, an order has been placed, or a subscription has renewed. It is the Customer’s responsibility to cancel a subscription before the renewal date.

By placing an order, you request that work begins as soon as possible. Where applicable, you acknowledge that this means you waive any right to a 14 day cooling off period once the service has begun.

5.2 Cancellation confirmation requirement
Cancellation is only treated as confirmed when the Customer receives a cancellation confirmation from ST Mastering, for example an on screen confirmation, an email confirmation, or an account status change showing the subscription is cancelled. If the Customer cannot provide evidence of a confirmed cancellation, the subscription will be treated as active and any renewal will be valid, payable, and non refundable. If you believe a cancellation attempt failed for any reason, you must contact us before the renewal date so we can confirm the status and prevent renewal where possible.

5.3 Chargebacks and payment disputes
If you raise a chargeback or bank payment dispute for a renewal or service fee that is valid under these Terms, we reserve the right to provide our payment provider and your bank with relevant evidence, including account logs, billing history, renewal receipts, service delivery records, and communications showing the subscription status and or work performed. If a chargeback is raised without a confirmed cancellation, or after services have been delivered or work has begun, you remain liable for the fees due, and we may suspend access to services and delivery links, and recover reasonable costs and fees associated with the dispute process where permitted.
