Terms of Use

Effective as of July 14, 2026

These Terms ("Terms") govern the use of the sfxstacks.com website (the “Website”) and the SFX Stacks desktop application (the “App”) operated by ASR Tech Oy (Business ID 2946518-6), Minna Canthin katu 66 lh. 1, 70100 Kuopio, Finland (“Company”, “we”, or “us”).
The Website and App together are referred to as the “Service.”

By using the Website or the App, you agree to these Terms.
If you do not agree, you must not use the Service.

1 Intellectual Property

All software, text, graphics, logos, icons, and other materials included in the Website or App are the property of the Company or its licensors and are protected by copyright and other intellectual property laws.

You may view and use the Service for your own personal or internal business purposes. You may not copy, distribute, reverse-engineer, decompile, translate, or modify any part of the Service except where permitted by mandatory law or with our prior written permission.

2 License and Permitted Use

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable license to install and use the App on compatible devices in accordance with the access level available to you, including any Free version limits, Pro license limits, activation limits or seat limits.

You agree not to:

  • use the Service for unlawful purposes or to infringe third-party rights
  • circumvent, disable or interfere with license checks or technical protection measures
  • attempt to access the licensing backend or activation system in an unauthorised way
  • upload, distribute or use malicious code, or attempt to disrupt the Service
  • misrepresent the Service, our brand, or trademarks

We may suspend or terminate access to the Service if we detect abuse, fraud, or violations of these Terms.

3 Purchases and Licenses

Payments for Pro licenses are handled by Paddle Payments Ltd., who acts as merchant of record. Your purchase is also subject to Paddle’s buyer terms and privacy notice.

SFX Stacks may be available as a Free version with limited features. Paid Pro licenses are handled through Paddle.

Unless otherwise stated:

  • paid Pro licenses are sold as a one-time license with updates included unless otherwise stated
  • you are granted the number of activations / seats specified at the time of purchase
  • prices are shown in USD and converted to your local currency during checkout
  • applicable taxes (such as VAT) are added based on your billing country

We operate a separate licensing backend that stores licensing, activation, entitlement and trial information in order to apply Free and Pro access rules, enforce seat limits, provide support and prevent abuse. Details are described in our Privacy Notice.

3.1 Refund Policy

If you are a consumer within the EU/EEA, you may have a statutory right of withdrawal for distance contracts. SFX Stacks is delivered as digital content not supplied on a physical medium, and the license key is normally delivered immediately after payment.

If you expressly request immediate delivery during the statutory withdrawal period and acknowledge that this causes you to lose the right of withdrawal, that right may end once supply of the digital content has begun, to the extent permitted by applicable law.

Separate from any mandatory statutory rights, our general refund policy is:

  • you may request a refund within 14 days of purchase if the license has not been activated
  • after a license has been activated or otherwise used, refunds are generally not provided, except where mandatory consumer-protection law or Paddle's policies require otherwise

Refunds are processed through Paddle in accordance with applicable law and Paddle’s policies.

4 Disclaimer

The Website and App are provided “as is” and “as available”, without warranties of any kind, whether express or implied.
We do not guarantee that the Service will be uninterrupted or error-free, that it will meet your specific requirements, or that it will be compatible with all systems, plugins or workflows.

Nothing in these Terms excludes or limits any warranty or liability that cannot be excluded or limited under mandatory law.

5 Limitation of Liability

To the extent permitted by law, the Company shall not be liable for any indirect, incidental, special, consequential or punitive damages, or loss of profits, business, data or goodwill arising out of or in connection with the use or inability to use the Service.

To the extent permitted by law, our total aggregate liability for direct damages arising from the Service shall be limited to the amount you have paid for SFX Stacks licenses during the twelve (12) months immediately preceding the event giving rise to the claim.

Nothing in these Terms limits liability for intentional misconduct, gross negligence, death or personal injury, or any other liability that cannot be limited under mandatory law.

6 External Services and Links

The Website and App use different external services.

The Website uses third-party services including:

  • Paddle for purchases and payment processing
  • Fathom Analytics for cookieless website analytics
  • Amazon Web Services (AWS) for Website hosting and delivery through services including Amazon S3 and CloudFront
  • Cloudflare Turnstile for spam and bot protection on Website forms

The App may connect to:

  • the SFX Stacks API, operated by us, for trials, license activation, seat management, optional telemetry when enabled, and reports you choose to submit
  • updates.sfxstacks.com, operated by us, to check for and download application updates
  • Hugging Face to download the CLAP model used for local search and the optional local metadata-writing language model
  • PyTorch download servers when required local runtime components are downloaded
  • external browser links, which open websites outside the App

The SFX Stacks API and updates.sfxstacks.com are services operated by us, not third-party integrations. External browser links are ordinary links and do not give external websites access to the App or your local sound library.

Connections used for model, runtime and application downloads do not upload your audio files or local sound-library data. Third-party services are operated under their own terms and privacy practices, and we are not responsible for their content or availability.

7 Updates and Changes

We may update the Service (including the App) from time to time, for example to improve performance, add features, or address security or compatibility issues. Some updates may be required for continued use of the Service.

We may also update these Terms from time to time. The latest version is always available on the Website. Material changes will be announced via the Website or shown in the App.
If you continue to use the Service after changes take effect, you are deemed to have accepted the updated Terms.

8 Governing Law and Dispute Resolution

These Terms are governed by the laws of Finland, excluding its conflict-of-law rules.

If you are a consumer in the EU/EEA, you may also have the right to bring a claim in the courts of your country of residence and to use local consumer-dispute resolution bodies.

Otherwise, any disputes arising out of or relating to these Terms or the Service shall be submitted to the District Court of Kuopio, Finland.
