Limit Alexa Access
- Turn mics off when not using. The light ring turns red.
- Enable Alexa Guard when leaving home to only allow critical requests.
Review and Delete Recordings
- Regularly delete conversations under Privacy settings.
- Set recurring auto-delete option for recordings (every 3 months is ideal).
Secure Alexa Skills Access
- Disable skills you don‘t use so they can‘t collect voice data.
- Enable skill permissions on request instead of by default.
Limit Account Linking
- Be selective when linking email, calendar etc. to minimize data sharing.
- Use throwaway accounts if allowing third-party skill access.
Place Alexa Carefully
- Don‘t put Alexa in private rooms like bedroom, bathroom etc.
- Face Echo Dot away from conversations you don‘t want analyzed.
Familiarize Yourself
- Adjust mics, camera and voice control settings in the Alexa app.
- See what data Amazon collects and how it‘s used in their Privacy hub.
Following these best practices goes a long way towards using Alexa while maintaining your privacy!
