StumbleUpon Privacy Policy


StumbleUpon respects the privacy of its users. This Privacy Policy (“Privacy Policy”) informs you of StumbleUpon’s policies and practices regarding the collection and use of information you submit to us or which we collect about you through our Services and to inform you of options that you have to control or restrict the availability and use of your information.

1. ABOUT US. We are StumbleUpon, Inc. (“StumbleUpon”, “us”, “we” or “our”), a corporation registered under the laws of the state of Delaware in the United States with our principal office address at 301 Brannan Street, San Francisco, CA 94107, USA.

2. ABOUT THE STUMBLEUPON SERVICES. We provide users (“you”, “your” or “User(s)”) with services, delivered via the StumbleUpon website (currently located at http://www.stumbleupon.com), the StumbleUpon toolbar, the StumbleUpon mobile applications and/or any other platform or media through which we make such services available from time to time, that allow you to explore the Internet, find new websites that may be of interest to you, receive recommendations of websites from StumbleUpon, and join a community of individuals with similar tastes and interests (collectively, the “Services”). A User may be a “Member” (meaning a User that has registered and created an account with StumbleUpon or through one of StumbleUpon’s connected social networking communities (“Partner Communities“) and has a “StumbleUpon Profile”) or a “Visitor” (meaning a User simply browsing the website or viewing content from or affiliated with StumbleUpon), and may also include an advertiser or a developer that has created an account with StumbleUpon.

3. ABOUT THIS PRIVACY POLICY. This Privacy Policy informs you of StumbleUpon’s policies and practices regarding the collection and use of information you submit to us or which we collect about you through our Services and to inform you of options that you have to control or restrict the availability and use of your information. Wherever you reside or from whichever country you submit your information, you consent to our use of your information, consistent with this Privacy Policy, in the United States and in other territories where StumbleUpon provides its Services.

4. CHANGES TO THIS PRIVACY POLICY. StumbleUpon reserves the right to change this Privacy Policy from time to time. We will usually inform you of any changes by posting the updated Privacy Policy on the StumbleUpon website. If we make any material changes to our Privacy Policy, we will post a notification on the StumbleUpon website and, if you are a Member, notify you via email and/or by asking you to review the changes to the Privacy Policy the next time you login to access the Services. Your continued use of the Services after the changes are communicated as set forth in this section will indicate your consent to our use of your information consistent with this Privacy Policy, including those changes.

5. SOME TERMS WE USE IN THIS PRIVACY POLICY. Important terms that we use in this Privacy Policy are “Personal Information”, “Non-Identifying Information” and “Log Data”. To explain what we mean by these terms:

a. “Personal Information” is information about you that can be used to contact or identify you, such as your full name, address, e-mail address or phone number.

b. “Non-Identifying Information” means information that does not permit the identification of an individual person, such as the other information that you provide as part of registration and personalization of your StumbleUpon Profile (for example, individual preferences). Certain Non-Identifying Information would be considered a part of your Personal Information if it were combined with other identifiers (for example, combining your zip or postal code with your street address) in a way that enables you to be identified. But the same pieces of information are considered Non-Identifying Information when they are taken alone or combined only with other Non-Identifying information (for example, your viewing preferences).

c. “Log Data” is derived by our servers automatically as you interact with the Services, which record information that your browser sends whenever you visit a website. Log Data is a form of Non-Identifying Information.

6. WHY DOES STUMBLEUPON COLLECT INFORMATION? Our primary goals in collecting information are to improve our Services, features and content, to administer your use of our Services, and to deliver content that may be of interest to you.

7. WHAT INFORMATION DOES STUMBLEUPON COLLECT?

a. When you create a StumbleUpon Profile or connect through our Partner Communities, we will collect your e-mail address, gender, date of birth and specific or general location. When you personalize your StumbleUpon Profile, we will also collect any information you provide, such as your full name, your photo and any optional information you decide to supply about yourself, your lifestyle and your interests. If you register for our Services via a Partner Community, we will obtain certain Personal Information you have provided to the Partner Community (such as your name, profile picture, e-mail address). The information we obtain may depend on the privacy settings you have with the Partner Community.

b. We also collect from you some Non-Identifying Information about your interests as you navigate through our Services. For example, when you click on the rating buttons (thumbs up, thumbs down), or recommend a website by clicking “I like it!” in the StumbleUpon toolbar, you are explicitly sending information about your preferences for the website then displayed, which StumbleUpon will use to improve its recommendations to you and to others. We may also receive Non-Identifying Information about you and your interests from other sources like third parties that add to their websites StumbleUpon widgets or StumbleUpon badges.

c. When you enter any information (including Personal Information) into any postings or comments, we may collect this information, which may be available to some, a subgroup of, or even all Users of the Services, depending on how and where this information was posted by you and with whom you have elected to share the posting or comment.

d. When you leave us feedback or write to us directly, we will collect any information that is contained in your feedback form, which will include your e-mail address and other information that you may submit to us for reference or reply.

e. As mentioned, when you interact with the Services our servers automatically record Log Data that your browser sends whenever you visit a website. This Log Data may include information such as your computer’s IP (Internet Protocol) address, your mobile device identifier, the geographic location of the IP address you are using to access the Internet, browser type, operating system (including identifying whether you are connecting via a mobile device), the time of day of your access, your general physical location or your more specific location if you are connecting through your mobile device, and the website that you visited immediately prior to StumbleUpon.

8. HOW DOES STUMBLEUPON USE INFORMATION? We use your Personal Information in some cases in conjunction with your Non-Identifying Information to recommend and deliver to you personalized content from across the web, including from advertisers, based on your expressed preferences and inferred interests. Log Data is used to monitor and analyze use of the Services, to determine the composition of and engage our user base, to analyze usage patterns, to optimize your access to our Services, and to control the load on our servers so that we can serve you better. We also combine your Personal Information with Non-Identifying Information and Log Data and aggregate it with information collected from other Users to attempt to provide you with better recommendations, to improve the quality and performance of our Services and to analyze and understand how our Services are used. We may use your e-mail address to inform you about changes to our Services, and, should you agree to receive such communications from us, send you newsletters or promotional e-mails about the Services.

9. HOW CAN YOU EDIT YOUR INFORMATION OR SETTINGS? As a Member you may choose to edit the Personal Information that is in your StumbleUpon Profile so that different or less information is available to the public. For example, if you choose not to be searched for by other Members via your e-mail address, you may adjust your settings so that other Members will not be able to find you by your e-mail address. Further, if you want to keep your declared interests or aspects of your StumbleUpon Profile private, you may turn on your privacy filter so other Users cannot determine which websites you have rated, or which categories of websites you have viewed. When you receive newsletters or promotional communications from us, you may indicate a preference to stop receiving further communications from us and you will have the opportunity to “opt-out” by following the “unsubscribe” instructions provided in the e-mail you receive. We may, however, still send you administrative e-mails regarding the Services. You may email us here with a request that we delete your Personal Information from our database. We will use commercially reasonable efforts to honor your request. We may retain an archived copy of your records as required by law or for legitimate business purposes.

10. HOW CAN YOU CHANGE OR DELETE INFORMATION? All Members may review, update, or correct the Personal Information in their StumbleUpon Profile by logging into their account.

11. HOW DOES STUMBLEUPON USE COOKIES?

They are used by web developers to help users navigate their websites efficiently and perform certain functions. More information about cookies is available at: http://www.allaboutcookies.org/.

b. What kinds of cookies does StumbleUpon use? We may use both session cookies (which expire once you close your browser) and persistent cookies (which remain for a certain period of time unless deleted) to provide Non-Identifying Information to us about Users. We also collect Non-Identifying Information about your immediate web history and interests through StumbleUpon badges and widgets that appear on third party websites.

c. What does StumbleUpon use cookies for? StumbleUpon will use Non-Identifying Information collected using cookies and tracking technology: (i) to deliver to Members websites or other content we think may be of interest to you; (ii) to connect you with other Members with similar interests; (iii) for analytics purposes, to monitor usage of our website, to reengage users, and improve user experience; and (iv) to remember choices you make in order to improve user experience. StumbleUpon does not share your browsing information with third party advertisers.

d. Your Options: Most browsers are initially set up to accept cookies. You can reset your browser to refuse all cookies or to indicate when a cookie is being set. Instructions to remove persistent cookies can be found through your Internet browser. You may also choose to opt out of tracking so that websites like StumbleUpon cannot learn from your interactions and viewing history. If you wish to opt out of tracking, you may follow the “Do Not Track” instructions here. Be aware that if you choose to disable cookies or opt out of tracking some areas of the Services may not be optimized for your use, you may not be able to access any or all of the functionality of the Services and your experience using the Services will not be personalized to your interests.

12. WHEN DOES STUMBLEUPON SHARE INFORMATION, AND WITH WHOM?

a. Sharing via the StumbleUpon Profile. The information provided in your StumbleUpon Profile that you select to be publicly displayed via your privacy settings will be public information and any User will be able to view it. This information may also be “crawled” by third party search engines so that Personal Information in your StumbleUpon Profile may be accessible through search engines in search results. Also, when you enter any information (including Personal Information), into postings or comments via the Services, this information, may be available to some, a subgroup of, or even all Users of the Services, depending on how and where this information was posted by you and with whom you have elected to share the posting or comment. You may edit or delete information in your StumbleUpon Profile at any time so that it is no longer accessible to the public.

b. Invitations to Friends. If you use the StumbleUpon Services to invite a friend to join StumbleUpon or if you share a website with a friend, your friend’s e-mail address will be stored. StumbleUpon stores this information so that we may send these messages and to improve our social sharing programs. Your friend may contact us here to request that we remove this information from our database.

c. Aggregate Information and Non-Identifying Information. We may share aggregated information that does not include Personal Information and we may otherwise disclose Non-Identifying Information and Log Data with third parties for industry analysis, demographic profiling, marketing, and other purposes relating to our Services. Any aggregated information shared in these contexts will not contain your Personal Information. We do not share Personal Information with advertisers.

d. Service Providers. We may employ third party companies and individuals to facilitate our Services, to provide the Services on our behalf, to perform site-related services (e.g., without limitation, maintenance services, database management, web analytics and improvement of the Services’ features) or to assist us in analyzing how our Services are used. These third parties have access to your Personal Information only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.

e. Business Transfers. If StumbleUpon or the assets of StumbleUpon are acquired by another company, we may transfer your information in connection with that acquisition or sale and the acquiring company will possess the information (including your Personal Information) collected by us and it will assume the rights and obligations described in this Privacy Policy.

f. Compliance with Laws and Law Enforcement. We will access and disclose your Personal Information to government or law enforcement officials or private parties if we believe in good faith that such disclosure is necessary to comply with relevant laws, to respond to valid legal process such as a search warrant, subpoena, statute, or court order, to protect the property and rights of StumbleUpon or a third party, to protect the safety of the public or any person, or to prevent or stop activity we may consider to be, or to pose a risk of being, illegal, unethical or legally actionable.

13. HOW LONG WILL STUMBLEUPON RETAIN INFORMATION? Unless there is a specific legal or regulatory requirement for us to keep information, we will retain it for no longer than is reasonably necessary for the purposes for which the data was collected or for which it is to be further processed.

14. WHERE WILL INFORMATION BE COLLECTED AND STORED? StumbleUpon is located in the USA. Accordingly, Personal Information we collect may be transferred to and stored in our servers or those of third parties that act on our behalf (such as hosting providers) in the USA or other countries outside of the European Economic Area. By using the Services you agree to such collection, transfer and storage outside of the European Economic Area.

15. HOW SECURE IS THE INFORMATION? You should be aware that while we take reasonable measures to maintain the security of your Personal Information, we are not able to fully eliminate all security risks or potential breaches.

16. WHAT IS THE POLICY TOWARDS CHILDREN? Children under the age of 13 are not eligible to create a StumbleUpon Profile or to use the Services. We do not knowingly gather Personal Information about Users who are under the age of 13. If a parent or guardian becomes aware that his or her child has provided us with Personal Information without their consent, he or she should contact us here. If we become aware that a child under 13 has provided us with Personal Information, we will delete such information from our files.

17. WHAT POLICIES APPLY TO THIRD PARTY WEBSITES, SERVICES AND APPLICATIONS? Our provision within the Services of links or referrals to other websites, services or applications is for your convenience and does not signify our endorsement of such other websites, services or applications or their content. Links to other websites may also be posted or referred by Members. We have no control over, do not review, and cannot be responsible for these outside websites or their content. This Privacy Policy does not govern your visit to these other websites, and your access is entirely at your own risk. These other websites, services and applications may set their own cookies on users, collect data, or solicit personal information. You should refer to any privacy policies found on such websites, services and applications to understand how your information may be collected and used.
