`useGVLData()` currently powers the built-in `IABConsentDialog`, but it is **not part of the public package surface**.

Older docs showed it as a public hook. That is no longer accurate.

If you need supported customization points today:

* Use `IABConsentBanner` and `IABConsentDialog` from `@c15t/react/iab` for the supported prebuilt UI
* Use `useHeadlessIABConsentUI()` from `@c15t/react/iab` when you need lower-level control over banner/dialog state and actions

> ℹ️ **Info:**
> Until useGVLData() is exported as public API, avoid importing it from deep internal paths. Those paths are not covered by semver guarantees and can change without notice.

When a public GVL-focused hook becomes part of the supported API, this page should document that public surface instead of the internal dialog hook.
