How to Lock Down Siri and Protect Your iPhone Privacy

Siri is convenient, but it can also listen more than many people realize. If Siri is enabled everywhere by default, it can access information you may prefer to keep private, such as contacts and messages, call history, location data, and app usage.


Who Is at Risk

Anyone who uses Siri on an iPhone, especially people who want to keep private conversations and personal information secure.

What to Watch For

Pay attention to Siri settings that may allow it to be activated or store your voice requests more than you want.

What to Do

Steps to increase your privacy include disabling “Hey Siri” if you don’t need it, limiting Siri on the lock screen, controlling which apps Siri can access, turning off Siri suggestions, and reviewing and deleteing Siri history.
