# Third-party notices — Analytics Dashboard Studio

The Studio is proprietary software (see `LICENSE`, © 2026 Polecat.live). It vendors and
redistributes the third-party and public-domain components listed here, each under its own
license. Vendored files keep their upstream license text alongside the code (never our
proprietary header), and anything the Studio **inlines into exported dashboards** carries the
required notice inside the export too.
