MyLMU is a web application for tracking and analyzing Le Mans Ultimate (LMU) telemetry and race sessions. Users can upload session result XML files and native telemetry recordings from their LMU installation directory, and the application automatically ingests race result logs to provide comprehensive racing history with detailed lap-by-lap telemetry, performance analytics, and community comparisons—all accessible from any device.

The application allows sim racing enthusiasts to:

Upload and import race result XML files from Le Mans Ultimate
Track and analyze racing statistics and telemetry data
View detailed race histories, lap times, and performance metrics
Access comprehensive analytics including track-specific insights and community comparisons
Optionally use the MyLMU Sync Agent desktop application for automatic file monitoring and uploads

Features and Required Permissions

Google OAuth Authentication

MyLMU uses Google OAuth to allow users to sign in with their Google account. This provides a convenient authentication method for users who prefer not to create a separate account.

Permissions Requested:

Basic Profile Information: Name, email address, and profile photo
Purpose: To create and secure user accounts, personalize the user experience, and display user information within the application

This information is used solely for authentication and account management. We do not access, store, or share any other Google account data beyond what is necessary for authentication.

Race Data Storage and Processing

Users upload race result XML files, which are processed to extract statistics and telemetry data. This data is stored securely in our database and is only accessible to the user who uploaded it.

Data Collected:

Race results (track name, car name, session type, positions, lap times)
Lap-by-lap telemetry (sector times, fuel consumption, speeds, positions)
Race metadata (date, duration, laps completed, pit stops, tire compounds)
User account information (email, driver name, preferences)

Optional Desktop Sync Agent

Users may optionally install the MyLMU Sync Agent, a Windows desktop application that monitors the LMU Results folder and automatically uploads new race files. This feature requires:

File system access to the user-selected LMU Results directory
Network access to upload files to MyLMU servers
Basic device information for compatibility and update delivery

The Sync Agent only monitors the folder explicitly selected by the user and does not access other directories or files on the user's computer.

Data Usage and Security

All user data is stored securely using industry-standard encryption. We implement Row Level Security (RLS) to ensure users can only access their own data. Authentication credentials are handled securely through Supabase Auth, and passwords are never stored in plain text.

We do not sell, rent, or share user data with third parties except as necessary to provide the service (e.g., using Supabase for database storage and Google for OAuth authentication).
