Does My Apple Watch Record Me?
Apple Watch does not continuously record ambient audio, but it does record your voice when you use Siri, make calls, or use Walkie-Talkie. It also continuously records health data (heart rate, blood oxygen, ECG, sleep, activity) and location when you use location-based features. According to Apple's privacy policy, Siri audio may be retained for up to six months. Health data is encrypted end-to-end and not used for advertising.

How to Limit What Apple Watch Records
Disable Siri on Apple Watch
Open Watch app on iPhone → Siri → turn off "Listen for Hey Siri" and "Raise to Speak". This prevents voice recording for Siri.
Delete Siri history
iPhone Settings → Siri & Search → Siri & Dictation History → Delete Siri & Dictation History. This removes stored audio from Apple's servers.
Control app microphone access
iPhone Settings → Privacy & Security → Microphone → toggle off any apps you do not want accessing the Apple Watch microphone.
Disable location tracking
iPhone Settings → Privacy & Security → Location Services → set individual apps to "Never" or "While Using". Apple Watch Workout can be set separately.
Opt out of health research
Health app → Browse → Research Studies → leave any studies you have joined. This stops your anonymised health data being shared with researchers.
Disable iCloud Health sync
iPhone Settings → [Your Name] → iCloud → Health → toggle off. Health data will remain on-device only and not sync to Apple's servers.
