Google now has a dedicated page to control all your privacy and security and a lot more! It has a flat and clean UI which makes it very easy and fun to customize these settings.
Here is some of what you can do here:
- Take the Privacy Checkup and Security Checkup, our simple, step-by-step guides through your most important privacy and security settings.
- Manage the information that can be used from Search, Maps, YouTube and other products to enhance your experience on Google. For example, you can turn on and off settings such as Web and App Activity, which gets you more relevant, faster search results, or Location History, which enables Google Maps and Now to give you tips for a faster commute back home.
- Use the Ads Settings tool to control ads based on your interests and the searches you’ve done.
- Control which apps and sites are connected to your account.
