Last modified: January 15, 2021
You can control what information is collected, stored and shared when you use the Google Chrome browser on your computer or mobile device, Chrome OS and enable Safe Browsing in Chrome. This data protection notice describes special Chrome functions, however, all personal data that is transmitted to Google or stored in your Google account is used and protected in accordance with Google's data protection declaration in its currently valid version. Google's data retention policy describes how and why Google retains data.
Details on the data protection information
The Beta, Dev, and Canary versions of Chrome allow you to test new Chrome features that are being developed. This privacy notice applies to all versions of Chrome, but may not be current for features under development.
For detailed instructions on how to manage your privacy settings, see this overview of Chrome's privacy settings.
Table of Contents:
You don't need to provide any personal information to use Chrome. However, Chrome offers several modes that you can use to adjust or improve your browser usage. How data protection is handled depends on the mode used.
Basic browsing mode
In the basic browser mode, information is stored locally on your system. This information can include:
Browsing history information: In Chrome, for example, B. The URLs of the pages you visit, text, images and other resources of these pages are saved. If the function for predicting network actions is activated, some IP addresses linked on these pages are also stored.
Personal information and passwords to help you fill out forms or log in to websites you visit
A list of permissions you've given specific websites
Cookies or data from the websites you have visited
Data saved by add-ons
A directory of files downloaded from websites
You can manage this information in different ways:
The personal data stored by Chrome will only be sent to Google if you have this data stored in your Google account by activating synchronization. For passwords, payment cards and information, you will need to select specific login details or payment cards and information to be stored in your Google Account. Additional Information.
How Chrome handles your information
Information for website operatorsStandard log information is automatically sent to websites you visit with Chrome, including your system's IP address and information from cookies. By using Chrome to access Google services such as B. to access Gmail, Google generally does not receive any additional personal data. If Chrome detects signs of being attacked by someone or a company on the network ("man-in-the-middle attack") on Google websites and other websites that participate in this process, Chrome may send information about them Connection to Google or the website you visited to help determine the extent and functionality of the attack. Google provides participating website owners with reports of attacks that have taken place on their websites.
Pre-rendering: To make web pages load faster, Chrome has a function that fetches IP addresses from links on a web page in advance and establishes appropriate network connections. Websites and Android apps can also instruct the browser to preload the pages you might visit next. Requests for preloading by Android apps are controlled with the same setting as the predictions initiated by Chrome. Preload requests from websites, on the other hand, are always honored regardless of whether Chrome's ability to predict network actions is enabled. When Chrome, a website, or an app prompts you to pre-render, the preloaded website can set and read its cookies as if you had visited them. This is true even if you ultimately don't visit the pre-rendered page. additional Information
Location: For more geographically relevant information, you can use Chrome to share your location with a website. Chrome will not allow any website to access your location information without your consent. On mobile devices, however, Chrome will automatically share this information with your default search engine if the Chrome app has access to location information and you haven't blocked location for that website. Chrome uses Google Location Services to determine your approximate location. Chrome can send the following information to Google location services:
- WiFi router in your area
- Identification of the transmission masts in your area
- Strength of your WiFi or cellular connection
- The IP address currently assigned to your device
Google has no control over third-party websites or their privacy practices. So be careful when sharing your location with a website.
Updates: Chrome regularly sends information to Google to check for updates, check the connection status and the current time, or estimate the number of active users.
Search functions: If you are signed in to a Google website and Google is your default search engine, searches you perform using Omnibox or the search box on the "New Tab" page in Chrome are saved in your Google Account.
Completion function: So that you can find what you are looking for more quickly, Chrome uses the completion function of your standard search engine to complete your previous input. If you search using Omnibox or the search box on the New Tab page in Chrome, the characters you type will be sent to your default search engine, even if you haven't pressed Enter yet. If Google is your default search engine, the completions are based on your search history, on topics relevant for the respective context that you enter in Omnibox or the search field on the "New Tab" page, and on the search queries of other users. Additional Information. Your browser history may also be used for completions. additional Information
Navigation aid: If you cannot connect to a web page, you can receive alternative suggestions for pages that are similar to the page you are looking for. To do this, Chrome sends the URL of the page you are trying to reach to Google.
Auto-fill function, password management and payments: Chrome sends Google limited, anonymous information about the web forms you see or submit, including the hash of the web page URL and form structure details while auto-fill or password management is enabled. This will enable us to improve the “auto-complete” function and password management. Additional Information.
If you've signed in to Chrome with your Google Account, Chrome may offer to save passwords, payment methods, and similar information to your Google Account. You may also be offered the option to add passwords and payment methods from your Google Account to web forms. If you've saved passwords or payment methods on your device in Chrome, you may be asked there to save them to your Google Account as well. When you use a payment method from your Google Account or save your payment method to your Google Account for future use, Chrome will collect information about your computer and share it with Google Pay to protect you from fraud and to provide the service. If the merchant supports the option, you can also pay with Google Pay in Chrome.
language: So that your browser usage can be customized based on the languages you prefer, Chrome saves the most frequently used languages of the websites you visit. This language preference is sent to Google so that your browser usage can be customized in Chrome. If Chrome sync is enabled, this voice profile will be linked to your Google account. If you also include the Chrome history in your Google Web & App activities, your use in other Google products can also be personalized with it. Go to activity settings
Web apps on Android: On Android, when you select "Add to Home" for a website optimized for fast, reliable performance on mobile, Chrome uses a Google server to create a native Android package for that website on your device . With this Android package, you can interact with the web app just like you would with an Android app. The web app will also appear in the list of your installed apps. additional Information
Usage statistics and crash reports: By default, usage statistics and crash reports are sent to Google to help us improve our products. Usage statistics include B. Information on settings, button clicks, performance statistics or memory usage. In general, usage statistics do not include website URLs or personally identifiable information. However, if you have "Improve search queries and surfing / send URLs of pages you visit to Google" enabled, Chrome usage statistics will include information about the web pages you visit and how you use them. If Chrome Sync is enabled, Chrome may combine the age and gender information on your Google Account with our statistics to help us develop products that are suitable for all demographics. For example, we may collect statistics to identify web pages that are loading slowly. We use this data to improve our products and services and to provide web developers with information on how to improve their websites. Crash reports contain system information from the time of the crash and, under certain circumstances, URLs of websites or personal data, depending on what was happening at the time the crash report was triggered. We may share aggregated, non-personal information with the public and our partners, such as publishers, advertisers, or web developers. You can choose to send usage statistics and crash reports to Google at any time. Additional Information. If you have Google Play apps enabled on your Chromebook and Chrome usage statistics are enabled, Android diagnostic and usage data will also be sent to Google.
Media licenses: Media is encrypted on some websites to prevent unauthorized access and copying. In the case of HTML5 websites, the key exchange required for this takes place via the Encrypted Media Extensions API. When deciding whether to allow access to the medium, session identifiers and licenses can be saved locally. The user can delete these markings in Chrome using the Clear browsing data option. The box "Cookies and other website data" must be ticked. For websites with Adobe Flash Access, Chrome provides a unique identifier for content partners and websites. The identification is saved in your system. You can prevent this access in the settings under "Content settings"> "Protected content". To reset the flag, select Clear browsing data and click the "Cookies and other website data" box. When accessing protected content in Chrome on Android or offline or higher quality content on Chrome OS, content providers can request a certificate from Chrome to verify the device's eligibility. A website-specific tag sent to the website confirms that the device's cryptographic keys are protected by the Chrome hardware. additional Information
Other Google services: This data protection notice describes the Google services activated by default in Chrome. Chrome can also offer other Google web services. If you z. For example, to access a page in a different language, Chrome offers to send the text to Google for translation. The first time you use these services, you will be informed of your options for managing them. For more information, see the Google Chrome privacy white paper.
Labels in Chrome
Chrome contains a number of unique and ambiguous identifiers that are required for various functions and services. If you z. For example, if you have push notifications enabled, a label will be created to send notifications to you. Wherever possible, we use ambiguous labels and remove those that are no longer needed. The following markings also help us to further develop, sell and promote Chrome without being directly related to a Chrome function.
Installation tracking: Each copy of the Windows desktop version of the Chrome browser has a temporary, randomly generated installation number that is sent to Google when you install and use Chrome for the first time. This temporary flag helps us estimate the number of browsers installed and will be deleted the first time Chrome is updated. The mobile version of Chrome continuously uses a variant of the device ID to record the number of Chrome installations.
Ad tracking: To help us better track the success of advertising campaigns, Chrome generates a unique token that is sent to Google the first time the browser is run and used. In addition, search queries from the Omnibox contain an ambiguous advertising tag if you received or re-activated your desktop version of the Chrome browser as part of an advertising campaign and Google is your default search engine. All mobile versions of the Chrome browser also contain an ambiguous advertising tag for search queries via the Omnibox. Under certain circumstances, Chrome OS is also used regularly, e.g. B. Sent an ambiguous advertising tag to Google during initial setup and when performing Google searches. More information
Field tests: Sometimes we do limited testing of new features. Chrome includes a seed number that is randomly selected the first time it is run to assign browsers to different trial groups. The tests can be limited to certain countries (based on the IP address), to operating systems, to a Chrome version and to other parameters. All requests sent to Google include a list of the field tests currently running on your Chrome installation. additional Information
Sign in and sync Chrome modes
You can also use the Chrome browser while signed in to your Google Account, regardless of whether syncing is turned on.
- browser history
- Passwords and AutoFill information
- Other browser settings, such as B. installed extensions
The synchronization will only be activated if you want it to. Additional Information. You can use the \ "Settings \" menu to specify which information should be synchronized. Additional Information. Under Chrome data in your account, you can view and manage the amount of Chrome data saved for your Google account. In the dashboard, you can also turn off synchronization and delete all linked data from the Google servers. However, this does not apply to Google Accounts created through Family Link. Additional Information. Sign in to Google Accounts created through Family Link. Synchronization cannot be turned off here because it provides administrative functions for parents, including: Website restrictions. However, children with Family Link accounts can delete their data and turn off syncing for most types of data. Additional Information. The privacy notices for Google accounts created with Family Link apply to Chrome sync data stored in those accounts.
How Chrome handles your synced information
If you activate synchronization with your Google account, we will use your browser data to improve and personalize your use of Chrome. You can also personalize your use of other Google products by including your Chrome history with your Google Web & App activity. additional Information
You can change this setting on the Account History page or manage your private data at any time. If you do not use your Chrome data to personalize your Google usage outside of Chrome, Google will only use your Chrome data after it has been anonymized and combined with data from other users. Google uses this data to develop new functions, products and services and to improve the quality of existing products and services as a whole. If you want to use Google's cloud to store and sync your Chrome data without Google accessing the data, you can encrypt your synced data with a sync passphrase. additional Information
Incognito mode and guest mode
You can limit the information Chrome stores on your system by using incognito mode or guest mode. Chrome does not save certain information in these modes, such as: B .:
- Basic browsing history information such as URLs, cached page text, or IP addresses of pages linked on the websites you visit
- Snapshots of the pages you have visited
- Lists of your downloads, even if the files you downloaded remain elsewhere on your computer or device
How Chrome handles your information in incognito or guest mode
Cookies: Chrome does not share existing cookies with websites that you visit in incognito or guest mode. However, new cookies can be placed in your system while you are using these modes. However, these are only saved and transferred as long as at least one incognito or guest window is open.
Changes to the browser configuration: If you make changes to the browser configuration, e.g. For example, if you save a web page as a bookmark or change your settings, this information is saved. Incognito or guest mode has no effect on saving these changes.
Permissions: Permissions that you grant in Incognito mode are not saved in your existing profile.
Profile information: In incognito mode you still have access to information from your existing profile, e.g. B. on suggestions based on your browsing history and saved passwords. In guest mode, you can surf the web without seeing information from existing profiles.
Manage users in Chrome
Manage users for personal use from Chrome
You can set up personalized versions of Chrome for multiple people using the same device or computer. Note that anyone with access to the device can see all information in all profiles. If you want to prevent others from seeing your data, use the built-in user accounts in your operating system. additional Information
Manage users in Chrome for Enterprise
Some Chrome browsers and Chromebooks are administered by a school or business. In this case, the administrator can apply policies in the browser or on the Chromebook. The first time a user starts the browser, Chrome connects to Google to review these guidelines. The exception to this is guest mode. Chrome regularly checks for updated policies.
An administrator can set up a status and activity reporting policy for Chrome, including location information for Chrome OS devices. In addition, your administrators may be able to view, monitor, use, or disclose data accessed through your managed device.
Google Chrome and some third-party browsers such as: B. some versions of Mozilla Firefox and Safari have the Safe Browsing function from Google. When using Safe Browsing, information on suspicious websites is exchanged between the browser used and Google servers.
How Safe Browsing works
Your browser will regularly connect to Google servers to download the latest Safe Browsing list of known phishing and malware websites. The current version of this list is saved locally in your system. Google does not collect account information or other personal data as part of this contact, but receives standard log information, such as B. an IP address and cookies.
Every website you visit is compared with the safe browsing list in your system. In the event of a match, your browser will send a partial copy of the hash value of the URL of this website to Google so that Google can send further information to your browser. Google cannot determine the actual URL from this information. additional Information
The following Safe Browsing features are only available in Chrome:
If you have activated the "Advanced Safe Browsing" mode, Chrome takes additional protective measures as described in the browser settings and sends additional data to Google. More information can be found here. Some of these protective measures may also be available in the "Standard protection" mode as independent functions and can be controlled individually.
If you have "Improve searches and browsing / URLs of the pages you visit are sent to Google" and enabled Safe Browsing, Chrome will send the full URL of every website you visit to Google to see if it's safe. In addition, if you sync your browsing history without a sync passphrase, these URLs will be temporarily linked to your Google Account so that safeguards can be more personalized. This feature is disabled in incognito and guest modes.
Some versions of Chrome have Safe Browsing technology that detects potentially harmful websites and potentially dangerous file types that are still unknown to Google. The full URL of the website or potentially dangerous file can also be sent to Google to determine if it is actually a malicious website or file.
Chrome uses Safe Browsing technology to regularly scan your computer for unwanted software that is preventing you from changing your settings or otherwise compromising the security and stability of your browser. More information can be found here. If Chrome finds what it is looking for, you can download the Chrome Cleanup Tool to remove the relevant software.
If you visit a website that contains potential malware or if Chrome detects unwanted software on your computer, you have the option to send additional data to help us improve Safe Browsing. additional Information
If you use Chrome's password manager and enter a saved password on an unknown page, Safe Browsing will run a check on Google to protect you from phishing attacks. As part of this safeguard, Chrome won't send your passwords to Google. Safe Browsing also protects your Google account password. If you enter it on a website that could be a phishing website, Chrome will prompt you to change the password. If you sync your browsing history or are signed in to your Google Account and choose to notify Google, Chrome will also send you an alert stating that your Google Account has likely been the target of a phishing attack.
If you're signed in to your Google Account, Chrome will warn you if you use a username and password that may have been revealed in the event of a data breach. When you sign in to a website, it is checked by Chrome sending part of a hash of your username and other encrypted information about your password to Google. Google then returns a list of possible matches from known data breaches. This list can help Chrome determine if your username and password have been leaked. Google does not find out your username or password, and also not whether they have been disclosed. This function can be deactivated in the Chrome settings. additional Information
For desktop and Android versions of Chrome, you can deactivate the Safe Browsing function at any time in the Chrome settings. For iOS versions of Chrome, the Safe Browsing technology used on your device is managed by Apple and data may be sent to Safe Browsing providers other than Google.
Dealing with data protection in apps, extensions, designs, services and other add-ons
Before installing an add-on, you should find out which permissions are requested via the add-on. Add-ons can e.g. B. have the following permissions:
- Store, access and share data stored locally or in your Google Drive account
- Viewing content on websites you visit
- Use of notifications sent through Google servers
Chrome can interact with add-ons in a number of ways:
- When checking for updates
- When downloading and installing updates
- When sending usage indicators for the add-ons to Google
Some add-ons may require access to a unique identifier to manage digital rights or to transmit push notifications. You can turn off the use of flags by removing the add-on from Chrome.
Occasionally, Google may come across an add-on that poses a security threat or that violates the Developer Terms of Service for the Chrome Web Store or any other legal agreement, law, regulation, or policy. Chrome periodically downloads a list of these dangerous add-ons to remotely disable or remove from your system.
Information on data protection for server logs
As usual with websites, our servers automatically record which pages you call up when you visit our website. These "server logs" normally contain your web request, the IP address, the browser type, the browser language, the date and time of your request and one or more cookies that can uniquely identify your browser.
The following example shows a typical log entry, in this case for a search for the term "cars", followed by a breakdown of the individual components:
- is the IP address that the internet provider assigns to the user. Depending on the type of connection, the user can be assigned a different address each time he connects to the Internet.
- refers to the date and time of the search query.
- is the requested URL including the search query.
- is information about the browser and operating system used.
- is the unique cookie ID that was assigned to the respective computer when visiting a Google website for the first time. Cookies can be deleted by the user. If the user has deleted the cookie from their computer since the last time they accessed Google, this is a unique cookie ID that is assigned to them as soon as they access Google again from this computer.
To use some of our services, you need to create a Google account and provide some personal information. This usually includes your name, your email address and a password. This account information can be used to authenticate you when you access Google services and to protect your account from unauthorized access by other users. You can edit or delete your account at any time through your Google Account Settings.
