Terms of Service and End User License Agreement

1. About Us and These Terms

These Terms of Service and End User License Agreement (the "Terms") govern purchases from and use of digital products and services supplied through developdevice.com by Jaroslav Holub, trading as Develop Device / Develop Device Studio ("Develop Device", "we", "us" or "our").

Trader: Jaroslav Holub / Develop Device Studio
Identification Number (IČO): 03872441
VAT ID (DIČ): CZ8509251685

By placing an order, downloading, installing, accessing or using a Product, or commissioning a Service, you agree to these Terms and any applicable product description or service scope agreed for your order. If you do not agree, do not purchase, download, install or use the relevant Product or Service.

Nothing in these Terms excludes, restricts or overrides mandatory consumer rights that apply to you under the law of your country of residence.

2. Products and Services

We sell and supply digital music-production products and content, including presets, profiles, impulse responses (IRs), drum sounds and presets, samples, MIDI content, DAW templates, bundles, software/plugins, installation materials and other downloadable digital audio-production tools ("Products").

We may also provide customized or bespoke services, including personalized presets, profiles, templates, mixing, mastering or other production-related work ("Services"). The specific description, deliverables, required customer input, timeline and revisions for a Service may be stated on the product page or otherwise agreed in writing.

3. Orders, Prices and Payment

Prices and available payment methods are shown at checkout. Applicable taxes may be included in or added to the displayed price as shown at checkout. Payment must be successfully authorized before digital delivery or work begins, unless we expressly agree otherwise.

We may reject or cancel an order before supply where reasonably necessary, including for suspected fraud, abuse, payment failure, manifest pricing or listing error, legal restriction or inability to supply the ordered Product or Service. If we cancel a paid order before supplying it, we will refund the amount paid for the cancelled item, subject to applicable law and payment-provider processing times.

4. Digital Delivery and Access

Products are delivered electronically, normally through a download link, email and/or your customer account after successful payment. No physical item is shipped for a digital Product. Our Delivery Policy provides further information.

You are responsible for providing an accurate email address, securing your account and download links, downloading purchased files promptly, maintaining your own backups and meeting any stated hardware or software requirements.

Download links and account access are for the purchaser or licensed end user only. We may prevent unauthorized access, excessive link sharing, attempted piracy or other breach of these Terms. Loss of access due to your breach does not entitle you to a voluntary refund, subject always to mandatory rights.

5. License Grant for Digital Products

Unless a product page or separate written license states otherwise, upon full payment we grant the purchasing end user a non-exclusive, non-transferable, non-sublicensable license to use the purchased Product for personal or commercial music and audio-production purposes, subject to these Terms.

You may:

  • install and use a Product on devices that you own or control for your own work;
  • use presets, profiles, IRs, samples, MIDI content, templates and plugins in your own original music, recordings, performances, mixes, masters and audiovisual productions;
  • commercially release and monetize finished musical or audiovisual works created using the Product; and
  • deliver finished rendered audio or audiovisual works to your clients without owing additional royalties to us, unless a specific Product expressly states otherwise.

Your purchase is a license to use the Product; ownership of the Product files, software, presets, source content and associated intellectual property is not transferred to you.

6. License Restrictions

You must not, unless we expressly permit it in writing or applicable law requires otherwise:

  • sell, resell, redistribute, sublicense, share, rent, lend or make any Product or download link available to any other person;
  • share account credentials or enable another person to access purchased downloads;
  • upload Products to file-sharing services, marketplaces, public repositories, torrent sites, cloud libraries shared with others or artificial-intelligence/training datasets;
  • extract, repackage, distribute or sell Product components as standalone presets, profiles, impulse responses, samples, MIDI files, templates, wavetables or other source assets;
  • use Products to create, train, assemble or distribute a competing preset pack, profile pack, sample library, template pack, plugin-content library or substantially similar product;
  • remove, conceal or alter copyright, trademark, license or proprietary notices;
  • reverse engineer, decompile, disassemble or attempt to derive source code from software Products, except only to the extent that applicable law does not permit this restriction; or
  • claim ownership or authorship of a Product itself.

7. Product Requirements and Third-Party Software

Many Products are intended for use with third-party hardware or software, such as a DAW, drum library, amp modeler or plugin. Unless expressly stated, your purchase does not include required third-party software, hardware, expansions or licenses.

You must review the product description, supported format, software or hardware requirements and version requirements before purchase. References to third-party brands and products indicate compatibility or intended use only and do not imply affiliation or endorsement unless expressly stated.

8. Custom and Bespoke Services

For a Service, you agree to provide complete, accurate and lawful instructions and source files reasonably necessary to carry out the work. You confirm that you have the necessary rights to any recordings, stems, MIDI, presets, reference materials or other content you provide to us, and you grant us a limited license to use those materials solely to perform and support your Service.

Service delivery timing depends on project scope, queue position and timely customer feedback. Where a service description or agreement specifies included revisions, deliverables, communication requirements or project closure terms, those terms form part of your order.

A Service is not defective merely because creative preferences differ, provided the agreed scope and stated deliverables have been performed with reasonable care. Mandatory rights for services that are not performed as agreed or with required care remain unaffected.

9. Refunds, Withdrawal and Problems With Supply

Our Refund, Withdrawal and Digital Content Policy forms part of these Terms and governs refunds, cancellations, withdrawal rights and remedies for Product or Service issues.

Because digital Products cannot practically be returned once made available, accessed or downloaded, we do not provide voluntary refunds merely because you change your mind, prefer a different sound, lack the required third-party product, purchased an incorrect format or no longer need the Product, except where we expressly agree or applicable law requires otherwise.

A request for a refund is not automatically approved. If you report a defect, incorrect delivery or material mismatch with the product description, we may ask for information reasonably needed to assess the issue and may first provide the correct file, restore access, correct the defect or otherwise bring the Product or Service into conformity, where permitted by applicable law.

10. Fraud, Abuse, Payment Disputes and Evidence

You must not submit knowingly false, misleading or abusive refund requests, payment disputes or chargebacks, or falsely claim that a Product was not delivered, was unauthorized or was not as described.

To protect customers and our business, and to investigate or respond to support requests, suspected fraud, refund requests and payment disputes, we may retain and provide relevant records to our payment providers, platforms, advisers or authorities where appropriate. Such records may include order information, product descriptions applicable at the time of purchase, payment status, communications, account activity, delivery confirmations and download or access records made available by our delivery providers.

Nothing in this section prevents you from exercising a genuine statutory right or raising a good-faith dispute about a Product or Service.

11. Updates and Support

Unless expressly promised for a particular Product, future updates, added content, compatibility updates and continued download availability are provided at our discretion. This does not affect your rights concerning the Product supplied at purchase or updates required under applicable mandatory law.

Support is provided on a reasonable-efforts basis through support@developdevice.com. You are responsible for securing your files, project data and backups before installing or using any Product.

12. Intellectual Property

Products, store content, branding, documentation, audio demonstrations, graphics and other materials supplied by us are owned by or licensed to Develop Device and are protected by copyright and other intellectual property laws. Except for the limited license expressly granted in these Terms, no rights are granted to you.

You retain rights in your original finished musical and audiovisual works made using Products in accordance with these Terms, and in materials that you lawfully supply for a custom Service.

13. Disclaimers

To the maximum extent permitted by applicable law, Products and Services are provided on the basis described on the applicable product or service page. We do not guarantee that a Product will suit every creative preference, operate with software or hardware not listed as compatible, or produce a particular artistic or commercial result.

Any disclaimer in these Terms applies only to the maximum extent permitted by law and does not exclude mandatory guarantees, statutory conformity rights or remedies that cannot legally be excluded.

14. Limitation of Liability

To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, consequential or special loss, lost profits, lost opportunities, loss of data or business interruption arising from use of a Product or Service.

To the maximum extent permitted by applicable law, our aggregate liability arising from a Product or Service will not exceed the amount you paid for the Product or Service giving rise to the claim.

Nothing in these Terms limits liability that cannot legally be limited, including liability for fraud, willful misconduct, gross negligence where it cannot be excluded, death or personal injury caused by negligence where applicable, or your mandatory consumer rights.

15. Termination of License

If you materially breach these Terms, including by unauthorized distribution or sharing of a Product, the license granted to you may terminate immediately. Upon termination, you must cease use and delete all copies of the affected Product in your possession or control, except where retention is required by law.

Termination due to your breach does not create a right to a voluntary refund and does not affect rights or remedies that arose before termination.

16. Governing Law and International Customers

These Terms and any non-contractual obligations arising from them are governed by the laws of the Czech Republic, without regard to conflict-of-law rules.

If you are a consumer, this choice of law does not deprive you of mandatory protections available under the laws of your habitual residence that cannot be excluded by agreement. Any jurisdiction clause applies only to the extent permitted by mandatory law.

17. Changes to These Terms

We may amend these Terms for future transactions or future use of Services by publishing an updated version on this page and updating the effective date. The terms and license applicable to a Product already purchased are those in effect at the time of purchase, except for changes required by law or expressly accepted by you.

18. General

If a provision of these Terms is found invalid or unenforceable, it will be limited or removed only to the extent necessary, and the remaining provisions will continue to apply. A failure to enforce a provision immediately is not a waiver of that provision.

These Terms, together with the applicable product or service description, our Refund Policy, our Delivery Policy and any written terms specifically agreed for a custom Service, form the agreement applicable to the transaction.
