WolframAlpha Privacy Policy

We understand your concerns about how your information is used and shared, and we endeavor to use such information carefully and sensibly. This page explains how the information you provide is collected and used.

What Information Do We Collect?

We may collect both personally identifiable information about you and non-personally-identifiable information about your experience when you access the Wolfram|Alpha website.

The personally identifiable information we collect on our website or through our service consists of information you submit to us, including your name, email address, and other personal information that you willingly provide. Because participation in these activities is voluntary, you have a choice whether or not to disclose such information.

In addition to information that you provide to us through forms, we receive non-personally identifiable information whenever you interact with our websites, including your Internet Protocol (IP) address, browser type and version, geographical region, referral URLs, and other data automatically supplied by common web browsers.

How Is Your Information Used?

Information about our users is an important part of our business, and we are not in the business of selling it to others. We do not sell, rent, or lease your information to third parties.

The information we obtain from Wolfram|Alpha users helps us enhance and refine our service and content. Non-personal information collected about you through your experience and queries is used to better understand the entire population that is utilizing our website and how we might improve our services to improve the collective experience. Except as noted below, we track and record IP addresses that access our website for internal reporting, diagnostic, and analysis purposes only.

If you choose to receive communication from Wolfram|Alpha directly or via use of any submission forms associated with the website, we may send you an email response as well as notify you of other offers or services that may be of interest. When you send email or other communications to us, we may retain those communications to respond to you and improve our products and services.

Your IP address is used to determine, when possible, your approximate geographical location, which affects such things as your results' default currency and units of measure, based on what country you are in. Your browser type may be used to fine-tune the results for optimal display, for example on mobile devices or to work around limitations of a particular browser. Referrer URLs may be used to generate usage statistics and analyze usage patterns.

Other Disclosures of Your Information

We may release personally identifying information when we believe release is necessary to comply with lawful court orders. Any collected information associated with your use of the website (personal and non-personal) will be disclosed to government authorities or third parties only pursuant to a lawful request, subpoena, or other process that legally compels disclosure of that information.

We may also preserve, use, or disclose your information if necessary to enforce our Terms of Use and related agreements; to detect, prevent, or otherwise address fraud, security or technical issues, including high-volume use of the website; to respond to support requests; or to protect the rights, property, or safety of Wolfram|Alpha, our users, or others.


When you visit our website, we, like most websites, send one or more cookies—small anonymous identifiers—to your computer that uniquely identify you to our servers. While we do use cookies for security and fraud investigation purposes, our primary purpose is to enhance your user experience by understanding and remembering your preferences, and by general tracking of our user trends. Most browsers are initially set up to accept cookies, but you can configure your browser to accept all cookies, reject all cookies, or to notify you when a cookie is sent. Please be aware that Wolfram|Alpha may not have full functionality if your browser refuses cookies.

Links to Third-Party Websites

From time to time, Wolfram|Alpha may contain links to other websites. We do not exercise any control over these websites, and we are not responsible for their privacy practices or content. We encourage all users to read the privacy policies of each and every website visited when following links from the Wolfram|Alpha website. This privacy policy applies solely to information collected by Wolfram|Alpha.

Accessing Wolfram|Alpha from Third-Party Sources

Wolfram|Alpha may additionally be accessed through web widgets or gadgets that are embedded on third-party sites, such as iGoogle. If you choose to access Wolfram|Alpha via such tools, then depending on the third-party widget technology, your personal information and queries may be passed on to the third party's servers prior to being processed on the Wolfram|Alpha website.


We take appropriate measures to ensure the security of our website and systems. This includes precautions to safeguard your personal information against loss, theft, and misuse, as well as against unauthorized access, alteration, disclosure, or destruction of data.

Despite our efforts to protect your personal information, there is always some risk that an unauthorized third party may find a way around our security systems or that transmissions of your information over the internet may be intercepted. Your use of the website constitutes an acceptance of such risk.

Changes to This Privacy Policy

We may update or modify this Privacy Policy from time to time in the future. Any such updates or modifications shall be effective immediately upon their posting. Please refer back to this page often for the latest information.
