How extensions work in Gemini Apps

  • Gemini Apps only use extensions that are on in your Extensions settings. This includes extensions you turn on when you specify them in your prompt with an "@" mention.
  • Gemini Apps check for extensions that can help it generate a more helpful response. If a Gemini app finds an extension that can help, it automatically sends information from your conversation and other relevant information to that extension. For example, Gemini Apps will send your location data to Google Maps if you ask for coffee shops near you and the Google Maps extension is on.
  • Gemini Apps won’t access your personal content in other services without your permission. Some Gemini Extensions are designed to automatically work with tools, apps, and content on your device to help you seamlessly interact with it.
  • If you directly interact with another Google service in Gemini Apps, your activity might be saved by that other service. For example, if you watch a YouTube video in a Gemini app, YouTube may:
  • Gemini Apps can use extensions to help you connect with third-party apps and services. When they do, Gemini Apps share information with those apps and services to fulfill your requests. That information is then used by those third-party apps and services according to their own developers' privacy policies.
