What data ESP-IDF (Espressif IoT) collects
Your privacy policy must disclose each of the following data types when you use ESP-IDF (Espressif IoT).
When does ESP-IDF (Espressif IoT) trigger privacy obligations?
Data Flow Activation
ESP-IDF triggers compliance obligations the moment firmware begins collecting sensor readings, connection metadata, or device telemetry—before any cloud transmission occurs. The framework itself does not use cookies, but devices running ESP-IDF generate persistent device identifiers (MAC addresses, chip IDs) that function as unique identifiers under GDPR Article 4(1) and CCPA Section 1798.100.
Regulatory Thresholds
GDPR applies if:
- –Your ESP32 devices process data of EU residents (including environmental sensor data tied to location or behavior).
- –Device identifiers + sensor readings constitute personal data under GDPR Article 4(1).
