# Privacy Policy for ESP32 ALDL Dashboard
|
|
|
|
**Android Application**
|
|
**Version**: 0.1.0
|
|
**Last Updated**: June 14, 2026
|
|

|
|
|
|
## Overview
|
|
|
|
The **ESP32 ALDL Dashboard** is a free, open-source Android application designed for vehicle enthusiasts and tuners. It interfaces with GM OBD1 / ALDL-equipped vehicles (such as the 1986 Pontiac Fiero 1227170 ECM) using a custom ESP32 Bluetooth SPP bridge.
|
|
|
|
**Core Privacy Principle**:
|
|
This app collects **only vehicle engine telemetry data** from your car. All data is processed and stored **locally on your device**. The app makes **no network connections**, sends **no data** to any servers, and contains **no analytics, tracking, or crash reporting**.
|
|

|
|
## Data Collected
|
|
|
|
### What We Collect
|
|
The app receives and decodes the following vehicle diagnostic data via Bluetooth from your paired ESP32-ALDL device:
|
|
|
|
- Engine speed (RPM)
|
|
- Vehicle speed (MPH)
|
|
- Coolant temperature (°C / °F)
|
|
- Manifold Air Temperature (MAT)
|
|
- Manifold Absolute Pressure (MAP)
|
|
- Throttle Position Sensor (TPS) voltage
|
|
- O2 sensor voltage
|
|
- Battery voltage
|
|
- Spark advance
|
|
- Base Pulse Width (BPW)
|
|
- Idle Air Control (IAC) position
|
|
- BLM and Integrator fuel trim values
|
|
- Status flags (Closed Loop, Rich/Lean, TCC Lockup, A/C Clutch, etc.)
|
|
- Active diagnostic trouble codes (DTCs)
|
|
|
|
**Source**: This data comes exclusively from **your vehicle's Engine Control Module (ECM)** through the ALDL port and the ESP32 Bluetooth bridge you provide and pair.
|
|
|
|
### What We Do **NOT** Collect
|
|
- No personal information (name, email, phone, etc.)
|
|
- No device identifiers or advertising IDs
|

|
|
- No user accounts or authentication data
|
|
- No photos, contacts, files, or other personal content
|
|
- No analytics or usage statistics
|
|
- No crash reports sent to third parties

|
## How Data Is Collected
|
|
|
|
- **Exclusively via Bluetooth Classic SPP** connection to your user-paired ESP32-ALDL device.
|
|
- The app never initiates internet connections or uses any network APIs.
|
|
- An optional **simulation mode** generates synthetic local data for testing without requiring hardware.

## Changes to This Policy
|
|
|
|
We will update this policy if the app's data handling changes. The latest version will always be available in the app (Settings → About) and in the project repository.

|
|
Because the app has no servers or user accounts, we cannot notify you directly of changes.
