 {: .table .table-bordered .table-striped }
 
 | Name | Scope | Description | Example | Type |
-|------|-------|-------------|---------|------|
+| ---- | ----- | ----------- | ------- | ---- |
 | `seat` | required | Seat identifier provided by Floxis | `"testSeat"` | `string` |
-| `region` | required | Region identifier for routing | `"us-e"` | `string` |
-| `partner` | required | Partner identifier provided by Floxis | `"floxis"` | `string` |
+| `region` | optional | Routing region: `us-e`, `eu`, or `apac` (default: `us-e`) | `"us-e"` | `string` |
+| `partner` | optional | Partner identifier (default: `floxis`) | `"floxis"` | `string` |

+## Prebid Server
+
+The Floxis Prebid Server adapter is available in both Go (`prebid-server`) and Java (`prebid-server-java`). The server-side endpoint follows the pattern `https://{region}.floxis.tech/pbs`, where `{region}` is one of `us-e`, `eu`, or `apac` (default: `us-e`). When a non-default `partner` is configured, the region host is prefixed accordingly (`https://{partner}-{region}.floxis.tech/pbs`). User-sync is handled via the standard Prebid Server cookie-sync mechanism. For setup assistance contact <prebid@floxis.tech>.

+| `partner` | optional | Partner identifier (default: `floxis`) | `"floxis"` | `string` |
+
+## Floors Support
 
 The Floxis adapter supports the Prebid.js [Floors Module](https://docs.prebid.org/dev-docs/modules/floors.html). Floor values are automatically included in the OpenRTB request as `imp.bidfloor` and `imp.bidfloorcur`.
 
-### Privacy Support
+## Privacy Support
+
+Privacy signals (GDPR/TCF EU, US Privacy, GPP, COPPA) are provided by Prebid.js core / Prebid Server and forwarded on the OpenRTB request. The Floxis exchange enforces IAB TCF EU vendor consent (GVL ID 1609) and honors US Privacy and GPP US national/state opt-out signals.
+
+## First-Party Fallback Id (Storage Use)
+
+In browsers that block third-party cookies, the Prebid.js adapter maintains a first-party fallback identifier: a random v4 UUID stored under the key `flx_uid` in `localStorage` (preferred) and a cookie (~30-day lifetime), both scoped to the publisher's own origin. The id is per-publisher — it is never shared across sites — and is sent as `user.ext.floxisId`. It is used only as an identity of last resort when the Floxis `__fxId` cookie is unavailable. Storage details are disclosed at [floxis.tech/vendor-storage.json](https://floxis.tech/vendor-storage.json).
 
-Privacy fields (GDPR, USP, GPP, COPPA) are handled by Prebid.js core and automatically included in the OpenRTB request.
+All storage access goes through the Prebid.js `storageManager`, so it is gated by the standard `deviceAccess` configuration and GDPR purpose-1 consent under GVL ID 1609. Bidder-level storage access is denied by default and requires an explicit publisher opt-in — without it, no id is generated or sent (a safe no-op):
+
+```javascript
+pbjs.bidderSettings = {
+    floxis: {
+        storageAllowed: true
+    }
+};
+```
