TelemetryBlocker

A small BepInEx plugin for Unity games that blocks telemetry and device reporting on the client, using Harmony patches.

What it does

TelemetryBlocker patches the game at runtime so these calls never run:

Patch	Target	Effect
TelemetryInterceptor	LIV LCK telemetry (SendTelemetry, SendTelemetryAsync, Initialize, InitializeAsync, InitializeHttpClient, GetGeoLocation, LoadOrCreateDeviceId, SerializeTelemetryEvent, SetUserIdProvider)	Skips the methods, so no telemetry events or geolocation lookups are sent
DeviceInfoPatch	PlayFabClientInstanceAPI.ReportDeviceInfo	Stops device info being reported to PlayFab
ScreenTimeTrackerPatch	PlayFabHttp.InitializeScreenTimeTracker	Disables PlayFab screen-time tracking
HardwareIdPatch	Hardware ID getter	Returns a random ID, generated once per session, instead of the real one

Nothing is written to disk and nothing is sent anywhere. The plugin only skips existing calls.

Requirements

• A Unity game with BepInEx installed
• The game's own Assembly-CSharp, PlayFab and LIV.LCK assemblies (only needed to build)

Install

1. Build the project (see below) or download TelemetryBlocker.dll from Releases.
2. Copy TelemetryBlocker.dll into the game's BepInEx/plugins/ folder.
3. Start the game. Patches are applied when the plugin is enabled.

Build

1. Clone the repo.
2. Add references to BepInEx, 0Harmony, UnityEngine.CoreModule, Assembly-CSharp, PlayFab and LIV.LCK (from the game's Managed folder and BepInEx's core folder).
3. Remove or exclude the Stubs/ folder. It holds empty placeholder types so the project can compile without the game. If it is included, the plugin compiles against the placeholders instead of the real Harmony and patches will not be applied.
4. Build:

dotnet build -c Release

The output is bin/Release/netstandard2.1/TelemetryBlocker.dll.

Known issues

• HardwareIdPatch is missing its [HarmonyPatch(...)] target arguments (lost during decompilation), so it does nothing until they are restored.
• RemoveHarmonyPatches only resets a flag; it does not unpatch the game.
