Safeguarding your data
Google is committed to protecting data confidentiality and security. It is important to understand your privacy options, whether in the role of a publisher or a consumer. This page provides information on data collection and security for:
Google customers use tags on web pages and an SDK for mobile apps to enable Google measurement products. The measurement data collected helps customers understand their users’ needs and, optionally, personalize the user experience and offer relevant advertising (see Advertising personalization).
Google Analytics mainly uses first-party cookies to report on visitor (aka. user) interactions on Google Analytics customers’ websites. Users may disable cookies or delete any individual cookie. Learn more
In addition, Google Analytics supports an optional browser add-on that - once installed and enabled - disables measurement by Google Analytics for any site a user visits. Note that this add-on only disables Google Analytics measurement.
Where a site or app uses Google Analytics for Apps or the Google Analytics for Firebase SDKs, Google Analytics collects an app-instance identifier — a randomly generated number that identifies a unique installation of an App. Whenever a user resets their Advertising Identifier (Advertising ID on Android, and ID for Advertisers on iOS), the app-instance identifier is also reset.
Google Analytics is a data processor under GDPR because Google Analytics collects and processes data on behalf of our clients, pursuant to their instructions. Our customers are data controllers who retain full rights over the collection, access, retention, and deletion of their data at any time. Google’s use of data is controlled by the terms of its contract with Google Analytics customers and any settings enabled by customers through the user interface of our product.
To help customers manage their compliance needs, Google Analytics offers a collection of tools, detailed below, that enable you to control how data is collected, and whether it is used for advertising personalization.
If you have linked Google Analytics to another product, please refer to Google Analytics linking overview.
Google operates as a data processor for Google Analytics. This is reflected in our Ads Data Processing Terms, which are available to all Google Analytics customers with direct contracts with Google. Learn more
Google Analytics is a data processor under LGPD because Google Analytics collects and processes data on behalf of our clients, pursuant to their instructions. Our customers are data controllers who retain full rights over the collection, access, retention, and deletion of their data at any time. Google’s use of data is controlled by the terms of its contract with Google Analytics customers and any settings enabled by customers through the user interface of our product.
We are committed to having a lawful basis for data transfers in compliance with applicable data protection laws.
For customers who use the Google Analytics for Apps SDK, we collect an App Instance Identifier, which is a number that is randomly generated when the user installs an app for the first time.
Google uses Google Analytics data to provide the Google Analytics measurement service to customers. Identifiers such as cookies and app instance IDs are used to measure user interactions with a customer’s sites and/or apps, while IP addresses are used to provide and protect the security of the service, and to give the customer a sense of where in the world their users come from. Customers may also choose to use the data collected by Google Analytics for site/app personalization or advertising purposes, including ads personalization (See Advertising Personalization below).
We do not share Google Analytics data without the customer’s authorization (including via settings in the product user interface), or as otherwise expressly permitted under the terms of their Google Analytics agreement, except in limited circumstances when required by law.
Customers may control their own access to data in their Analytics accounts or properties by configuring view and edit permissions for employees or other representatives who may login to their Analytics account. Learn more
Security-dedicated engineering teams at Google guard against external threats to data. Internal access to data (e.g., by employees) is limited by strict access controls (both internal policy controls and automated technical controls such as authentication, SSL, and security logs) to only those with a business need to access it.
Where customers link their Analytics property to another Google product or service account (“Integration Partner”), certain data from that Analytics property may be accessed and exported into the linked account. Once data is exported through a linking integration, it becomes subject to the Integration Partner’s terms and policies.
Note that once data is sent to an Integration Partner, that the data sent is subject to the terms of that Integration Partner and that Google Analytics no longer maintains access or control over that data.
Customers may review and manage their product integration linkings at any time within the Analytics product linking summary user interface.
With the Data Retention controls, customers can limit or expand the duration for which their user-level and event-level data is stored in Google Analytics servers. All customers should review their Data Retention settings and ensure the appropriate retention is selected.
If any of 1) all property-level data, 2) individual events, or 3) specific event names or user properties have been excluded from ads personalization, then Analytics will append an additional signal (called ‘npa’) in Postbacks indicating that networks should not use the data for personalized advertising. Note that each network's treatment of such 'npa' signal is determined by such network.
Google has earned ISO 27001 certification for the systems, applications, people, technology, processes, and data centers serving a number of Google products, including Google Analytics. or learn more about ISO 27001.
In web-based computing, security of both data and applications is critical. Google dedicates significant resources towards securing applications and data handling to prevent unauthorized access to data.
Data is stored in an encoded format optimized for performance, rather than stored in a traditional file system or database manner. Data is dispersed across a number of physical and logical volumes for redundancy and expedient access, thereby obfuscating it from tampering.
Google applications run in a multi-tenant, distributed environment. Rather than segregating each customer's data onto a single machine or set of machines, data from all Google users (consumers, business, and even Google's own data) is distributed among a shared infrastructure composed of Google's many homogeneous machines and located in Google's data centers.
To minimize service interruption due to hardware failure, natural disaster, or other catastrophe, Google implements a comprehensive disaster-recovery program at all of its data centers. This program includes multiple components to eliminate single points of failure, including the following:
Data replication To help ensure availability in the event of a disaster, Google Analytics data stored in Google's distributed file system is replicated to separate systems in different data centers.
Geographical distribution of data centers Google operates a geographically distributed set of data centers that is designed to maintain service continuity in the event of a disaster or other incident in a single region.
Resilient and redundant infrastructure Google's computing clusters are designed with resiliency and redundancy in mind, helping minimize single points of failure and the impact of common equipment failures and environmental risks.
Continuity plan in the event of disaster In addition to the redundancy of data and regionally disparate data centers, Google also has a business-continuity plan for its headquarters in Mountain View, CA. This plan accounts for major disasters, such as a seismic event or a public-health crisis, and it assumes people and services may be unavailable for up to 30 days. This plan is designed to enable continued operations of our services for our customers.
