+# NGX Monitor Privacy Policy
+
+Effective date: 2026-05-11
+
+NGX Monitor is a mobile client for monitoring Nginx servers that you configure in the app.
+
+## Data Stored On Your Device
+
+The app stores server profiles, monitor endpoint URLs, optional fallback LAN IP addresses, tags, alert thresholds, metric history, route diagnostics, alerts, and widget preferences on your device.
+
+If you save monitor tokens or Basic Auth credentials, the app encrypts them with Android Keystore before storing them locally.
+
+Android cloud backup and device transfer are disabled for app data.
+
+## Data Sent By The App
+
+The app sends monitor API requests only to endpoints that you configure. If you configure authentication, the app sends the configured token or Basic Auth credentials to that monitor endpoint.
+
+The app does not send your monitor data, credentials, server list, or usage data to the app developer.
+
+## Network Security
+
+HTTPS is recommended for monitor endpoints. The app also supports HTTP endpoints for private LAN monitoring when the user explicitly configures them.
+
+## Third Parties
+
+The app does not include advertising SDKs, analytics SDKs, or developer-operated crash reporting SDKs.
+
+Google Play may process app install, billing, review, crash, and device information according to Google's own policies.
+
+## Data Deletion
+
+You can delete server profiles inside the app. You can also remove all app data from Android system settings by clearing the app's storage or uninstalling the app.
+
+## Contact
+
+Replace this section with the publisher support email before submitting the app to Google Play.
