Google currently shares data across its services for the purposes described in its Privacy Policy at g.co/privacypolicy and depending on the previous choices you’ve made about your privacy settings, such as Web & App Activity, YouTube History, and Personalized ads

As of March 6, 2024, new laws in Europe will require Google to get your consent to link certain services if you want them to continue to share data with each other and other Google services as they do today. For example, linked Google services might work together to help personalize your content and ads, depending on your settings.
Services you can choose to link

You can choose which services to link from this list of Google services:

    Search
    YouTube
    Google Play
    Ad services
    Chrome
    Google Shopping
    Google Maps

All other Google services that are not listed here are always linked and therefore able to share data with each other for the purposes described in our Privacy Policy, depending on your privacy settings
What data is used

Personal data that is collected about your interaction with Google services can be shared across any linked services. This includes:

    Searches
    Videos you watch on YouTube
    Apps you install from Google Play
    Associated info, like your device info
    All the other types of info described in our Privacy Policy

How Google uses this data

Google uses data shared across linked services for all the purposes that are set out in our Privacy Policy:

    Providing personalized services, including content and ads, depending on your privacy settings
    Maintaining and improving our services
    Developing new services
    Understanding how people use our services to ensure and improve the performance of our services
    Performing other purposes described in our Privacy Policy

What won’t be affected

The choices you make about linked services will not change:

    The purposes for which Google uses data
    Your privacy settings, such as choices you have made about personalizing Google services
    Aspects of a service that don’t involve sharing data

The following can always be shared across Google services:

    Info that’s associated with your Google Account and not specific to any service, such as your profile picture or the info used to verify your identity
    Content or info you’ve chosen to make publicly available on Google services, such as comments you’ve posted on YouTube

Your data from all Google services, regardless of whether they are linked, may still be shared across all services for certain purposes, like preventing fraud, protecting against spam and abuse, and complying with the law.

Your data may also be shared across Google services to effectively help you complete tasks when two services are offered together. For example, if you make a purchase on Google Play, Play and Google Payments will share related info so that you can complete your purchase.
Things to know

Other settings let you control whether you see personalized content or ads. Linking Google services is not about sharing your data with third-party services

If services aren’t linked, some features that involve sharing data across Google services will be limited. For example, if you have personalization on for a service in your privacy settings but don’t link that service, you won’t get personalization based on data from other services, but can still get personalization based on data from that service.

You won’t be signed out of any Google services if you choose not to link services
How to manage linked services

You can manage your choices, including selecting other Google services to keep linked or withdrawing your consent, in your Google Account at myaccount.google.com/linked-services. You can also manage your other settings, like Web & App Activity, YouTube History, and Personalized ads, in your Google Account.
