These Terms and Software Licence ("Terms") apply to Stemwire audio plugins and related downloads. The product page, order details and any terms shown at checkout also form part of your agreement.

By downloading, installing or using a Stemwire plugin, you agree to these Terms. If you act for a business or other organisation, you confirm that you can bind it to these Terms.

01

PRODUCTS COVERED BY THESE TERMS

Stemwire develops software effects, software instruments and related digital files (each a "Plugin"). A Plugin may be offered free of charge, at a price you choose, for a fixed one-time price or under another model clearly stated on its product page.

02

ELIGIBILITY

You may use a Plugin only if you can legally enter into a binding agreement. If you are a consumer, you must be at least 18 years old. You must comply with laws that apply to your use of a Plugin.

03

PLUGIN LICENCE

3.1 Licence grant

Subject to these Terms, Stemwire grants you a non-exclusive, worldwide, non-transferable licence to install and use the downloaded version of the Plugin. The licence is perpetual for that version unless it is terminated under Section 13.

The licence is for one natural person. You may install the Plugin on devices that you own or control and use yourself. A company, studio, school or other organisation must obtain a separate licence for each person who uses the Plugin unless the product page or a written agreement expressly allows more users.

3.2 Music and other output

You may use the Plugin to create, perform, record, edit and distribute music, sound recordings, audiovisual works and other output for personal or commercial purposes. Stemwire claims no ownership of output you create with the Plugin.

3.3 Restrictions

Except where applicable law expressly permits it, you may not:

- share, sell, rent, sublicense, publish or redistribute the Plugin, its installer or any copy of it;
- make the Plugin available to another person through a shared account, server, service bureau or similar arrangement;
- copy the Plugin except for installation and reasonable backup purposes;
- remove or alter copyright, trademark or other proprietary notices;
- reverse engineer, decompile, disassemble or try to obtain the source code of the Plugin; or
- use the Plugin or its components to build or train a competing software product.

Any open-source or third-party component supplied with separate licence terms is governed by those terms where they conflict with this Section.

04

DOWNLOADS, COMPATIBILITY AND INSTALLATION

The product page states the supported operating systems, processor architecture, plugin formats, host compatibility and other material requirements known to us at the time. Check those requirements before downloading or paying.

You are responsible for installing the correct build and for maintaining a compatible computer, operating system, digital audio workstation and other required software. Compatibility with an unlisted host, future operating system or future hardware is not promised.

We may replace download files or stop offering an old build for security, legal or technical reasons. This does not end a valid licence for a copy you already obtained. Keep your own backup where the product page permits an unrestricted direct download.

05

PLUGIN UPDATES AND SUPPORT

A licence to a Plugin does not automatically include future major versions, new products or new features. We may provide maintenance releases, compatibility fixes or upgrades at our discretion.

This does not limit our obligation to provide consumers with updates, including security updates, required by applicable law for the period a consumer may reasonably expect. We will provide legally required information about such updates and the consequences of not installing them.

Unless we agree otherwise in writing, support is provided on a reasonable-efforts basis through hello@stemwire.io and no response time is guaranteed.

06

FREE AND CHOOSE-YOUR-PRICE PLUGINS

A Plugin offered for $0 may be downloaded and used under the same Plugin licence without a payment.

Where checkout lets you choose an amount, any amount above $0 is a voluntary price for the Plugin licence and digital product. It is not a charitable donation and does not buy additional features, ownership, priority support or broader licence rights unless the product page expressly says otherwise.

We may change the price or stop offering a Plugin for new downloads. A later price change does not affect a licence you already obtained.

07

POLAR CHECKOUT AND ONE-TIME PAYMENTS

Paid Plugin transactions may be processed by Polar Software, Inc. or its affiliate ("Polar"). Polar acts as merchant of record and authorised reseller for transactions completed through Polar Checkout. You buy the digital product from Polar, while Stemwire grants the Plugin licence and provides the product.

Polar handles payment collection, invoices, applicable transaction taxes, payment disputes and checkout-level refunds under the Polar Buyer Terms shown at checkout. The currency, price, tax and product shown in the final checkout summary apply to the transaction.

For a choose-your-price Plugin, the licence is the same whether you select $0 or a higher amount unless the product page expressly states otherwise.

08

ACCEPTABLE USE

You may not use a Plugin, its installer or Stemwire's download services to:

- break the law or another person's rights;
- distribute unlawful, infringing, abusive, fraudulent or malicious content;
- spam, phish, scrape, exploit or interfere with the security or operation of a product;
- gain unauthorised access to an account, system or network;
- bypass access, payment, licence or security controls; or
- resell or commercially provide the Plugin to third parties unless we agree in writing.

09

OWNERSHIP

Stemwire and its licensors own the Plugins, software, code, interfaces, designs, documentation, trademarks and other product materials, excluding your output and third-party material. These Terms grant a limited right to use the Plugin; they do not transfer ownership.

10

DIGITAL CONTENT, WITHDRAWAL AND CONSUMER REMEDIES

If you are a consumer, mandatory consumer law applies in addition to these Terms.

For digital content supplied immediately, you may be asked to expressly request immediate delivery and acknowledge that you lose the 14-day right of withdrawal once delivery begins, to the extent permitted by law. If the required consent, acknowledgement or confirmation is not obtained, your statutory withdrawal right is not limited by these Terms.

If a Plugin is not supplied, does not match the agreed description or compatibility information, lacks a legally required update or is otherwise defective, you may have statutory rights to correction, replacement, a price reduction or termination of the contract. Contact hello@stemwire.io with the product, version, order details if applicable, and a description of the issue. We will confirm and handle a consumer complaint within the time and in the manner required by law.

Nothing in these Terms excludes a warranty, remedy, withdrawal right or other consumer right that cannot lawfully be excluded.

11

BETA AND PRE-RELEASE SOFTWARE

A product identified as beta, preview, experimental or pre-release may be incomplete and may change or stop working. Do not rely on it for irreplaceable work. Any specific limits stated on its product page also apply. Mandatory consumer rights remain unaffected.

12

DISCLAIMERS

To the maximum extent permitted by law, Plugins are provided "as is" and "as available". We do not promise that every Plugin will meet every creative goal, work with unlisted systems, or be uninterrupted, secure or free of defects.

These disclaimers do not apply where a promise is expressly stated on a product page or at checkout, and do not limit rights that cannot be excluded under applicable law.

13

SUSPENSION AND TERMINATION

We may suspend downloads or terminate a Plugin licence where reasonably necessary because of a material breach, fraud, abuse, a security risk, a credible infringement complaint or a legal requirement.

We may terminate a Plugin licence if you materially breach its licence restrictions. Where the breach can be corrected, we will normally give you a reasonable opportunity to correct it first. When a Plugin licence ends, you must stop using and delete all copies of the Plugin.

Sections that by their nature should continue after termination, including ownership, licence restrictions, liability and dispute terms, will continue.

14

LIABILITY

Nothing in these Terms limits liability for fraud, wilful misconduct, death or personal injury where it cannot be limited, or any liability or consumer remedy that applicable law does not allow us to limit.

For business users only, to the maximum extent permitted by law:

- neither party is liable for indirect, incidental, special or consequential loss, or loss of profit, revenue, goodwill, opportunity, anticipated savings or data; and
- Stemwire's total aggregate liability relating to a Plugin or these Terms will not exceed the greater of EUR 100 or the fees paid for the affected Plugin during the 12 months before the event giving rise to the claim.

15

PRIVACY

Our Privacy Policy explains how Stemwire processes personal data. A Plugin may process data only as described on its product page or in the Privacy Policy.

16

CHANGES TO THESE TERMS

We may update these Terms for legal, security or product reasons. The version in force when you download a Plugin applies to that Plugin version unless a change is required by law or is needed to address security or abuse. Non-material changes may be posted on the website.

17

GOVERNING LAW AND COURTS

These Terms are governed by Czech law. If you are a consumer, this choice does not remove mandatory protection given to you by the law of your country of residence. A consumer may bring a claim in any court available under mandatory law. Other disputes will be resolved by the competent courts of the Czech Republic.

18

CONSUMER COMPLAINTS AND ADR

Please contact hello@stemwire.io first so we can try to resolve a complaint directly.

If a consumer dispute is not resolved, the competent out-of-court dispute resolution body is:

Česká obchodní inspekce

19

GENERAL TERMS

We are not responsible for delay or failure caused by events beyond our reasonable control.

You may not transfer these Terms or a Plugin licence without our written consent unless applicable law provides otherwise. We may transfer these Terms as part of a sale, merger, reorganisation or transfer of the relevant product or business.

If a provision is unenforceable, the remaining provisions continue. A failure to enforce a provision is not a waiver. These Terms, the relevant product page, order or checkout terms, the Polar Buyer Terms where applicable and the Privacy Policy form the agreement about the Plugin unless we agree otherwise in writing.
