+### Persistent Filters
+
+The filters you save in the data browser of Parse Dashboard are only available for the current dashboard user in the current browser session. To make filters permanently available for all dashboard users of an app, you can define filters in the `classPreference` setting.
+
+For example:
+
+```json
+"apps": [{
+  "classPreference": {
+    "_Role": {
+      "filters": [{
+        "name": "Filter Name",
+        "filter": [
+          {
+            "field": "objectId",
+            "constraint": "exists"
+          }
+        ]
+      }]
+    }
+  }
+}]
+```
+
+You can conveniently create a filter definition without having to write it by hand by first saving a filter in the data browser, then exporting the filter definition under *App Settings > Export Class Preferences*.
