+# Play Console Data Safety Notes
+
+Use this as a starting point for the Play Console Data safety form. Review it before submission because the final answers are your legal responsibility.
+
+## App Data Flow
+
+NGX Monitor is a client for monitor endpoints configured by the user. The developer does not operate a backend for this app.
+
+Stored locally on the device:
+
+- Server names, base URLs, tags, fallback LAN IPs, and alert thresholds
+- Monitor API tokens and optional Basic Auth credentials, encrypted with Android Keystore
+- Metric samples, alert history, route diagnostics, and widget preferences
+
+Transmitted by the app:
+
+- HTTP(S) requests to user-configured monitor endpoints
+- Authentication headers only for the specific endpoint configured by the user
+- Notification content generated locally on the device
+
+Not used by the app:
+
+- Advertising ID
+- Location APIs
+- Contacts, photos, camera, microphone, calendar, or SMS
+- Developer-operated analytics or crash reporting SDKs
+
+## Suggested Data Safety Answers
+
+- Data collected by developer: No
+- Data shared with third parties by developer: No
+- Data is encrypted in transit: Yes, when users configure HTTPS monitor endpoints
+- Users can request data deletion: Data is local; users can delete server profiles in-app or clear app data
+- App type: utility/productivity
+- Account creation: Not required
+
+Important note for the form: the app allows user-configured HTTP endpoints for private LAN monitoring. If you publish with HTTP support enabled, disclose that encryption in transit depends on the endpoint configured by the user.

+# Google Play Release Checklist
+
+This project is configured to build Google Play compatible Android App Bundles.
+
+## Current Project Readiness
+
+- Package name: `net.rodakot.ngxhttpmonitoringclient`
+- Minimum SDK: 24
+- Target SDK: 36
+- Version: `VERSION_NAME` / `VERSION_CODE` in `gradle.properties`
+- Release build: R8 minification enabled, resource shrinking enabled
+- App data backup: disabled for app data, databases, shared preferences, and files
+- Release signing: read from environment variables or `local.properties`
+
+## Create An Upload Key
+
+Create an upload keystore outside the repository:
+
+```powershell
+keytool -genkeypair `
+  -v `
+  -keystore "C:\secure\keys\ngx-monitor-upload.jks" `
+  -storetype JKS `
+  -keyalg RSA `
+  -keysize 4096 `
+  -validity 10000 `
+  -alias ngx-monitor-upload
+```
+
+Copy `local.properties.example` to `local.properties` and set:
+
+```properties
+NGX_RELEASE_STORE_FILE=C:\Users\meghdad\keystores\ngx-monitor-upload.jks
+NGX_RELEASE_STORE_PASSWORD=<redacted>
+NGX_RELEASE_KEY_ALIAS=ngx-monitor-upload
+NGX_RELEASE_KEY_PASSWORD=<redacted>
+```
+
+Do not commit `local.properties` or the keystore.
+
+## Build Release Artifacts
+
+Unsigned release sanity build:
+
+```powershell
+$env:GRADLE_USER_HOME='C:\Users\meghdad\AndroidStudioProjects\NGXhttpMonitoringClient\.gradle-user'
+.\gradlew.bat :app:bundleRelease --console=plain
+```
+
+Signed upload bundle, after signing values are configured:
+
+```powershell
+$env:GRADLE_USER_HOME='C:\Users\meghdad\AndroidStudioProjects\NGXhttpMonitoringClient\.gradle-user'
+.\gradlew.bat :app:bundleRelease --console=plain
+```
+
+Output:
+
+```text
+app/build/outputs/bundle/release/app-release.aab
+```
+
+## Before Uploading To Play Console
+
+1. Create the app in Play Console.
+2. Enable Play App Signing.
+3. Upload `app-release.aab`.
+4. Fill the store listing using `fastlane/metadata/android/en-US`.
+5. Upload phone screenshots and a 1024x500 feature graphic.
+6. Host `docs/PRIVACY_POLICY.md` as a public web page and paste that URL into Play Console.
+7. Complete Data Safety using `docs/PLAY_STORE_DATA_SAFETY.md`.
+8. Complete Content Rating. Suggested category: utility/productivity/server monitoring.
+9. Complete Target Audience. This app is for server administrators, not children.
+10. Run an internal test release before production.
+
+## Release Version Bump
+
+For every Play upload, increment `VERSION_CODE` in `gradle.properties`.
+
+Example:
+
+```properties
+VERSION_CODE=2
+VERSION_NAME=1.0.1
+```

+# 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.
