Your location

Does Google know my location?

Whenever you use the Internet, apps and sites can estimate roughly where you are, and the same is true for Google. Google may also know your precise location, depending on your device settings. (See How precise is my location?)

When you search on Google, like with Search, Maps or Google Assistant, your current location may be used to give you more helpful results. For example, if you search for restaurants, the most helpful results are probably for restaurants near where you are.

See How you can manage your location

How can I turn location on and off?

When you search on Google, Google will always estimate the general area that you’re searching from. Google, like any app or website that you use which connects to the Internet, can estimate your location based on your device’s IP address. For more, see How does Google know where I am?

To choose whether to send your precise location when you use Google, you can turn location permissions on or off for individual apps, sites and for your device.

If you set your home or work addresses, and Google estimates that you’re at home or work, then the exact address will be used for your search.

How precise is my location?

Your general area

When you search on Google, Google will always estimate the general area that you’re searching from. This way, Google can give you relevant results, and keep your account safe by detecting unusual activity, such as signing in from a new city.

A general area is larger than 1 sq mi. and has at least 1,000 users so that the general area of your search doesn’t identify you, helping to protect your privacy.

Your precise location

If you give your permission, Google can use your precise location. For example, Google needs your precise location to return the most relevant results for searches like 'ice cream near me' or turn-by-turn walking directions to a shop.

Precise location means exactly where you are, such as a particular address.

How does Google know my location?

Your location comes from different sources, which are used together to estimate where you are.

Your device’s IP address

IP addresses are roughly based on geography, similar to phone number area codes. This means that any app or website that you use, including google.com, can estimate the general area you’re in because of your IP address. Your device’s IP address is assigned to your device by your Internet Service Provider, and is required to use the Internet.

Your device location

If you give a Google app or site permission to use your device’s location, that information can be used to help understand where you are. Nearly all devices have a location setting built into the operating system, usually in settings.

Your activity on Google

Google can estimate the general area that you’re in based on your previous Google searches. For example, if you often search for pizza in Mumbai, it’s likely that you want to see results in Mumbai.

Your labelled places

If you set your home or work address, Google can use them to estimate where you are. For example, if you set your home address, and your IP address, previous activity or other sources of location information suggest that you may be near your home, then we will use your home location as an estimate of where you are.

Who can see my location?

It’s up to you. If you use Google Location Sharing, you can share your real-time location with friends and family across Google apps and sites.

Check if you’re sharing your location

Location Sharing is off by default. If you want to share your real-time location, you need to choose and confirm who you want to share with and for how long. You can stop sharing your location at any time.

See Sharing your real-time location with others

Data and personalisation

What data does Google collect about me?

When you use Google apps and sites, we collect information that we need in order to provide them to you, make them more useful to you, and for other reasons as explained in Why does Google collect data?.

With your settings, you can limit the data that we collect and how that data is used. For example, if you don’t want us to save your YouTube History to your Google Account, you can turn YouTube History off. See How can I decide what Google saves?

What is data?

Your personal information includes things that you provide to us which personally identify you, such as your name or email address. It also includes other data that can be reasonably linked to you by Google, such as information that we associate with you in your Google Account.

Your personal information includes two types of things:

Things that you provide or create

When you create a Google Account, you provide us with personal information like your name and a password.

You can also save content that you create, upload or receive from others, like email messages and photos.

Things that you do on Google

We collect information about your activity in our services, which can include things like the terms that you search for and the videos that you watch, people with whom you communicate or share content, and your Chrome browsing history, to deliver a better experience.

We collect information about the apps, browsers and devices that you use to access Google services, which helps us provide features like dimming your screen if your battery runs low.

We process your location, such as when you’re using features like turn-by-turn directions. For more, see the Location section.

Why does Google collect data?

We collect information that we need in order to provide our services, make them more useful to you, and for other reasons as explained in 'Ways we use data'.

For example, Google Maps can help you get to where you’re going while avoiding traffic because it combines information about where you are (your data) with public data (maps and information about public places).

Ways we use data

Provide our services

We use data to provide our services, like processing the terms that you search for in order to return results.

Maintain & improve our services

Data helps us maintain and improve our services. For example, we can track outages. And understanding which search terms are most frequently misspelled helps us improve spell-check features used across our services.

Develop new services

Data helps us develop new services. For example, understanding how people organised their photos in Google’s first photos app, Picasa, helped us design and launch Google Photos.

Provide personalised services, including content and ads

We use data to provide personalised content; for example, recommendations for videos that you may like. Depending on your settings and how old you are, we may show you personalised ads based on your interests.

Measure performance

We also use data to measure performance and understand how our services are used

Communicate with you

We might use your email address to send you a notification if we detect suspicious activity

Protect Google, our users and the public

We use data to keep people safer online, like detecting and preventing fraud

How does Google use data to personalise things?

'Personalisation' is about using the information that we collect to tailor our apps and sites to you, for example:

  • Recommendations for videos that you may like
  • Security tips adapted to how you use Google apps and sites (see Security Check-Up)

We also use data to personalise ads, except in cases, for example, when the setting is off or for certain ages.

Does Google personalise the ads that I see?

We try to make the ads that we show as useful as possible. But we don’t personalise ads for certain ages or for people who turn Ad Personalisation off.

We can still make ads useful even without personalising them. For example, if you’re looking at a page of results for 'new shoes', you might see an ad from a sports company. The ad can be based on general factors, like the time of day, your general location and the content of the page that you’re looking at.

You’re in control

How can I decide what Google saves to my account?

As you use a Google service, like Photos, there are settings that let you decide things, like whether you want to back up and sync your photos.

There are also settings that help personalise your experience across Google apps and sites. Two key ones are Web & App Activity and YouTube History.

When these controls are on:

  • Information about your activity on Google apps and sites is saved to your Google Account and
  • Saved information is used to personalise your Google experience

Web & App Activity

Saves your activity on Google sites and apps, like Search and Maps, and includes associated info like location. It also saves synced Chrome history and activity from sites, apps and devices that use Google services.

Your activity is used to give you faster searches, better recommendations and more personalised experiences in Maps, Search and other Google services.

YouTube History

Saves the videos that you watch and the things that you search for when you use YouTube.

Your YouTube History is used to personalise your YouTube experience and other apps, like your search results.

How do I delete My Activity data?

You can delete data saved in your Google Account. Data that you choose to permanently delete gets removed from our systems. We follow a careful process to make sure that this data is completely removed from our servers or kept only in a form that can’t be associated with you.

Visit My Activity to review the activity saved in your Google Account, such as things that you’ve searched for, read and watched. You can delete specific pieces of activity or all your activity within a specific time range.

You can also choose to have your activity deleted automatically.

How do I download my content?

Your content includes things like emails, photos, videos, docs, sheets, comments, contacts and calendar events.

Visit Download your data to create an archive of your content – either to back it up or to take it to another company if you want to try a different service.

What controls do I have when I’m signed out?

You have controls that let you choose how to use Google, even when you’re signed out. When you’re signed out, visit g.co/privacytools to change these settings:

Search customisation

Uses your Google searches from this browser for more relevant results and recommendations.

YouTube search and watch history

Uses your activity on YouTube, like videos that you watch and things that you search for, to personalise YouTube for you.

You can also block some or all cookies in your browser, but this can cause certain features across the web to stop working. For example, many websites require cookies to be turned on when you want to sign in.

Signed-out users can also choose whether they want to see personalised ads, though we don’t personalise ads for certain ages.
