Acceptable Use Policy

Introduction

This Acceptable Use Policy ("AUP") governs your use of Surkyl's services, including MueSync and all related products. It covers both content policies (what you can upload and share) and licensing policies (how you use your licenses and accounts).

We operate on a principle of good faith. We offer flexibility (unlimited devices, grace periods, generous quotas) because we trust our users. In return, we expect users to respect these systems and not abuse them.

This AUP is incorporated into and subject to our Terms of Service. Violation of this AUP may result in suspension or termination of your account.

Your Content Ownership

You own your outputs. Stems, processed audio, and other content you create using our Services belong to you. Our license is limited to providing the Services and does not grant us ownership of your creative work.

You are responsible for inputs. You must have the necessary rights to any content you upload or process through our Services. We are not responsible for verifying your rights to input content.

License Usage Policies

Our licensing model is built on good faith. We offer flexibility, and we expect users to respect these systems.

Device Policy

• All devices must be owned or controlled by you personally
• You may not install on devices owned by others to share your license

Seat Limits

Content Violations

Licensing/Account Violations

Reserved Rights

We reserve the right to:

• Report illegal activity to law enforcement

What We Consider "Hostile"

The following behaviors are considered hostile and will result in immediate termination without warning:

• License key sharing: Sharing license keys publicly or privately with unauthorized users
• Payment manipulation: Intentionally gaming grace periods or payment systems
• Reverse engineering: Any attempt to reverse engineer our software or AI models
• Circumvention: Any detected attempt to circumvent licensing or quota systems
• Chargeback fraud: Filing chargebacks after consuming services in bad faith
• Model extraction: Attempting to extract or recreate our AI models
• Credential sharing: Sharing account credentials to exceed seat limits

Why "hostile"? We offer good-faith systems (unlimited devices, grace periods, generous quotas) because we trust our users. Abusing these systems breaks that trust and harms the community. We respond accordingly.
