Licenses & open source notices
This page cleanly separates the proprietary StreamWizard license from open-source components, machine-generated third-party inventories, third-party platform terms, and privacy-related website notices.
For legal completeness, the machine-generated third-party list is always available. It complements the proprietary StreamWizard license but does not replace it.
