Your Alexa just responded to something you never said. Again. You're wondering what recordings Amazon has of your family conversations, and whether Google is listening to more than just "Hey Google" commands. After researching voice assistant privacy for three years and testing every major platform, I can tell you the privacy concerns are real – but completely manageable with the right settings.
Quick Answer: Voice assistant privacy requires 5 key steps: disable continuous listening, regularly delete voice recordings, turn off targeted ads, use privacy-focused wake words, and enable manual review deletion. These steps work across Alexa, Google Assistant, and Siri.
What Voice Assistants Actually Record
Understanding what gets recorded helps you make informed privacy decisions. Here's what each major platform actually captures:
Amazon Alexa Data Collection
- Voice recordings - Everything after you say "Alexa" (stored indefinitely by default)
- Text transcripts - Written versions of your voice commands
- Usage patterns - When you use skills, which smart devices you control
- Purchase history - Items ordered through voice commands
- Location data - If location services are enabled
Google Assistant Data Collection
- Voice recordings - Commands and conversations (linked to your Google account)
- Search queries - All voice searches and questions
- Device information - Which Google devices you use and when
- App interactions - Third-party services you connect
- Activity data - Combined with other Google services for ad targeting
Apple Siri Data Collection
- Anonymous voice clips - Short samples not tied to your Apple ID (after iOS 13.2)
- Device requests - What you ask Siri to do
- Correction data - When you correct Siri's mistakes
- Minimal personal data - Apple processes most requests on-device
The Real Privacy Risks You Should Know
Beyond the obvious recordings, voice assistants create these often-overlooked privacy vulnerabilities:
- False wake-up recordings - Devices activate from TV shows, conversations, or similar sounds
- Smart home device logs - Records of when you're home, room occupancy patterns
- Third-party skill data sharing - Apps can request access to your voice history
- Family member mixing - Systems may not distinguish between different household members
- Emergency service connections - Some situations automatically share location and recordings
5 Essential Privacy Steps for Alexa Users
Step 1: Delete Voice Recordings Regularly
Amazon stores Alexa recordings indefinitely by default. Delete them manually or set automatic deletion:
- Open the Alexa app → Settings → Alexa Privacy
- Select "Review Voice History" to see and delete individual recordings
- Enable "Enable deletion by voice" to say "Alexa, delete what I just said"
- Turn on automatic deletion after 3 months or 18 months
Step 2: Disable Targeted Advertising
Prevent Amazon from using your voice data for ads:
- Alexa app → Settings → Alexa Privacy → Manage Your Alexa Data
- Turn off "Use of Voice Recordings" for product development
- Disable "Interest-based ads" in Amazon account settings
- Block third-party access to voice recordings
Step 3: Control Smart Home Data Sharing
Limit what Alexa shares with connected smart home devices:
- Review connected skills and remove unused ones
- Check skill permissions and revoke unnecessary data access
- Disable location services for smart home skills that don't need it
- Use Groups to limit which devices can access specific data
5 Essential Privacy Steps for Google Assistant
Step 1: Manage Voice Recording Storage
Google ties voice recordings to your account. Control what gets saved:
- Visit myactivity.google.com → Voice & Audio
- Delete individual recordings or all voice data
- Turn off "Web & App Activity" to stop saving future recordings
- Enable auto-delete after 3, 18, or 36 months
Step 2: Disable Ad Personalization
Stop Google from using your voice data for targeted advertising:
- Go to adssettings.google.com
- Turn off "Ad personalization"
- Disable "Also use your activity & information from Google services"
- Remove voice and audio activity from ad targeting
Apple Siri Privacy Configuration
Apple processes most Siri requests on-device, making it the most privacy-friendly option. Still, configure these settings for maximum protection:
iOS/iPadOS Siri Privacy Settings
- Settings → Siri & Search → Turn off "Listen for 'Hey Siri'" if not needed
- Disable "Allow Siri When Locked" to prevent unauthorized access
- Turn off "Use with Ask Siri" for apps that don't need voice control
- Settings → Privacy & Security → Analytics → Don't Share With Apple
HomePod and Apple TV Settings
- Disable "Use Listening History" in Home app settings
- Turn off "Personal Requests" for shared devices
- Require authentication for sensitive commands
- Regularly check and delete Siri recordings in Settings
