1. General Terms

Welcome to OnyxOS. These Terms of Service ("Terms") cover your use of our platform, software, and services (collectively, "Services"). By creating an account or using our Services, you agree to these Terms. Our platform is designed to be country-agnostic, with specific addendums for local fiscal compliance where applicable.

1.2 Acceptable Use

You agree not to use the Services for any illegal purpose or in violation of any local, state, national, or international law.

2. Addendum for United States Users

Payment processing services are provided by Stripe. By using the OnyxOS Payments integration, you agree to be bound by the Stripe Connected Account Agreement.
