Privacy Statement

Last update: January 2015

Thank you for choosing to participate in a pre-release program for our next version of Windows! The purpose of the program is to enable you to provide usage data and feedback to Microsoft while trying out the pre-release software and services. Your participation is important and will provide us data we can use to better understand and engage our customers, and to improve our products and services. This privacy statement applies to the pre-release Microsoft Windows software, services and related experiences, including program websites and software that display or link to this notice (the “Program”).

The Program enables you or, if you are an organization, your end users, to purchase, subscribe to or use other products and services from Microsoft or third parties with different privacy practices. Your use of these other products and services is governed by their privacy statements and policies. For example, your use of Office apps is governed by the Office Privacy Statement at We strongly urge you to review their privacy statements and policies.

Data We Collect

Microsoft collects many kinds of information in a variety of ways to operate effectively and provide you the best products, services and experiences. We may combine this data with information that is linked to your user ID, such as information associated with your Microsoft account.

When you acquire, install and use the Program software and services, Microsoft collects information about your use of the software and services as well as about the devices and networks on which they operate. Examples of data we may collect include your name, email address, preferences and interests; location, browsing, search and file history; phone call and SMS data; device configuration and sensor data; voice, text and writing input; and application usage. For example, when you:

  • install or use Program software and services, we may collect information about your device and applications and use it for purposes such as determining or improving compatibility (e.g., to help devices and apps work together),
  • when you use voice input features like speech-to-text, we may collect voice information and use it for purposes such as improving speech processing (e.g., to help the service better translate speech into text),
  • when you open a file, we may collect information about the file, the application used to open the file, and how long it takes to use it for purposes such as improving performance (e.g., to help retrieve documents more quickly), or
  • when you input text, handwrite notes, or ink comments, we may collect samples of your input to improve these input features, (e.g., to help improve the accuracy of autocomplete and spellcheck).

The Program software and services may contain internet-enabled features and social functionality. When these features are used, they transmit certain standard computer information ("Standard Computer Data") to Microsoft. Standard Computer Data may include information about your computing environment such as IP address, network status, operating conditions and information about devices and software used with the Program software and services.

The Program software and services contain internet-enabled features that transmit performance or usage information to Microsoft (“Experience Data”). Experience Data may include information about performance and reliability, such as how quickly the software and services respond when you click a button or how many problems you experience with a given software or service. Experience Data may also include information about your use of software and services, such as the features used most often or how frequently you launch programs. Experience Data may be collected through the use of cookies or similar technologies; learn more below.

Microsoft automatically collects data from the devices you use with the Program software and services. This may include information about all aspects of the Program software and services, such as device performance, user interface interactions, and feature and application usage, including third party applications.

How We Collect Data

Microsoft uses a number of methods and technologies to gather data, such as:

  • Internet-enabled features in the Program software and services that transmit information to Microsoft; and
  • Technologies like cookies and web beacons. Microsoft may use cookies (small text files placed on a device’s hard disk by a web service) or similar technologies to provide the software and services. For example, cookies may be used to store a user’s preferences and settings, to gather Experience Data, to authenticate a user, or to detect fraud.

Microsoft takes measures designed to prevent the collection of email addresses and passwords, and numeric sequences such as phone numbers and credit card numbers.

How We Use Data

Microsoft uses data we collect from the Program software and services to operate, improve and personalize Microsoft products and services. For example, we use your voice data to improve speech recognition, we use your settings data to sync and roam your settings across devices, and we use information we learn about your interests to help make the content and ads we show you more relevant. Microsoft shares some data with our partners to improve how their products and services work with Microsoft’s products and services.

Microsoft may use your contact information (i) to communicate with you about your use of the Program software and services, and (ii) to provide you with additional information, which may be personalized, about the Program software and services, and other Microsoft and partner products and services. This contact may be by email, SMS, instant message, web chat, phone, in the user interface, or other means, and may include offers or ads.

Controlling the Transmission of Data

Use of the Program software and services is at your discretion. Many features that transmit data to Microsoft are enabled automatically. You will not have the option to turn off the transmission of data for certain features in the Program software and services.

To stop the transmission of all data, you must completely uninstall the Program software and services from all of your devices. This may require you to reinstall your device’s operating system.

Disclosure of Data

We will share your data with your consent, including as necessary to complete any transaction or provide any service you have requested or authorized.

We share some data collected in connection with the Program with third parties. For example, we may share data about the performance of a particular hardware or software component on your device with the manufacturer of that component to enable them to improve how their component works with Microsoft products and services.

We may share or disclose information about you with other Microsoft controlled subsidiaries and affiliates, and with vendors or agents working on our behalf. For example, companies we've hired to provide customer service support or assist in protecting and securing our systems and services may need access to personal information in order to provide those functions. In such cases, these companies must abide by our data privacy requirements and are not allowed to use the information for any other purpose. We may also disclose information about you as part of a corporate transaction such as a merger or sale of assets.

We may also access, disclose and preserve information about you when we have a good faith belief that doing so is necessary to:

  1. comply with applicable law or respond to valid legal process from competent authorities, including from law enforcement or other government agencies;
  2. protect our customers, for example to prevent spam or attempts to defraud Microsoft’s customers, or to help prevent the loss of life or serious injury of anyone;
  3. operate and maintain the security of our products and services, including to prevent or stop an attack on our computer systems or networks; or
  4. protect the rights or property of Microsoft, including enforcing the terms governing the use of the services—however, if we receive information indicating that someone is using our products or services to traffic in stolen intellectual or physical property of Microsoft, we will not inspect a customer’s private content ourselves, but we may refer the matter to law enforcement.

Data Handling

Microsoft is committed to protecting the security of your personal information. We use a variety of security technologies and procedures to help protect your personal information from unauthorized access, use or disclosure. For example, we store the personal information you provide on computer systems that have limited access and are in controlled facilities. When we transmit highly confidential information (such as a credit card number or password) over the Internet, we protect it through the use of encryption, such as the Secure Socket Layer (SSL) protocol.

Personal information collected by Microsoft may be stored and processed in the United States or any other country where Microsoft or its affiliates, subsidiaries or service providers maintain facilities. Microsoft abides by the U.S.-EU Safe Harbor Framework and the U.S.-Swiss Safe Harbor Framework as set forth by the U.S. Department of Commerce regarding the collection, use and retention of data from the European Economic Area and Switzerland.
