Under applicable law, Piazza is considered the "data controller" of the personal data we handle under this Privacy Notice. In other words, Piazza is responsible for deciding how to collect, use and disclose this data, subject to applicable law. Our contact information appears at the end of this Privacy Notice.
We obtain information about you through the means discussed below when we provide the Services. Please note that we need certain types of information to provide the Services to you. If you do not provide us with such information, or if you ask us to delete that information, you may no longer be able to access or use certain Services.
We collect information that you provide directly to us through:
Information about you. Certain parts of the Services may not require you to provide any information that can directly identify you by name (such as if you browse the website without logging in). Others may require information that can directly identify you. The specific types of information we collect will depend upon the Services you use, how you use them, and the information you choose to provide.
The types of data we collect directly from you includes:
Information about others. If you invite another person to join the Services, we collect their email address to send an invitation to use the Services and create an account. We may also collect (i) university and class or group information to invite students or instructors to enroll in that class or group on the Services or (ii) professional title and contact information if you are an enterprise customer inviting others in your enterprise to create company accounts.
When you use our Services, we collect certain information automatically as described in this Section. As discussed further below, we and our service providers (which are third party companies that work on our behalf), may use a variety of technologies, including cookies and similar tools, to assist in collecting this information.
Websites. When you use our website, we collect and analyze information such as your IP address, browser types, browser language, operating system, the state or country from which you accessed the Services, software and hardware attributes (including device IDs) referring and exit pages and URLs, platform type, the number of clicks, files you download, domain names, landing pages, pages viewed and the order of those pages, the amount of time spent on particular pages, the terms you use in searches on our sites, the date and time you used the Services and upload or post content, error logs, and other similar information.
Mobile Applications and Software. When you use a Piazza mobile application or app, we automatically receive certain information about the mobile phone, tablet, or computer you use, including device identifiers, IP address, operating system, version, Internet service provider, browser type, domain name and other similar information, whether and when you update the app, date and time of use, and how you use the app, including time spent in different portions of the application.
Location Information. When you use the Services, we and our service providers may automatically collect general location information (e.g., IP address, city/state and or postal code associated with an IP address) from your computer or mobile device. If you install our mobile app, we may ask you to grant us access to your mobile device's geolocation data. If you grant such permission, we may collect information about your precise geolocation, and we may use that information to improve the Services and provide you with location-based features (e.g. notify you of Events available near you). You can disable the GPS or other location-tracking functions on your device, provided your device allows you to do this.
We use the information that we collect through our Services for a variety of purposes, including to:
Aggregate/Anonymous Data. We may aggregate and/or anonymize any information collected through the Services so that such information can no longer be linked to you or your device. We may use such information for any purpose, including without limitation for research and marketing purposes, and may also share such data with our enterprise customers.
Piazza implements technical, administrative, and physical safeguards to protect the information provided via the Services from loss, misuse, and unauthorized access, disclosure, alteration, or destruction. However, no Internet or email transmission is ever fully secure or error free.
The laws of some jurisdictions such as the laws of the European Union require data controllers to tell you about the legal ground that they rely on for using, sharing, or disclosing of your information. To the extent those laws apply, our legal grounds are as follows:
We may use third-party web analytics services (such as those of Google Analytics) on our Services to collect and analyze usage information through cookies and similar tools; engage in auditing, research, or reporting; assist with fraud prevention; and provide certain features to you. To prevent Google Analytics from using your information for analytics, you may install the Google Analytics Opt-out Browser Add-on by clicking here.
If you receive email from us, we may use certain analytics tools, such as clear GIFs to capture data such as when you open our message or click on any links or banners our email contains. This data allows us to gauge the effectiveness of our communications.
Do Not Track (“DNT”) is a privacy preference that users can set in certain web browsers. We are committed to providing you with meaningful choices about the information collected on our website for third party purposes, and that is why we provide the variety of opt-out mechanisms listed above. However, we do not currently recognize or respond to browser-initiated DNT signals. To learn more about Do Not Track, you can do so here.
We may share or disclose information in the following ways:
We generally retain information for so long as it may be relevant to the purposes above and in compliance with applicable law. To dispose of any personal data, we may anonymize it, delete it or take other appropriate steps. Information may persist in copies made for backup and business continuity purposes for an additional period of time.
You have certain rights and choices with respect to your information such as:
Please note, however, that certain information may be exempt from such requests in some circumstances, which may include needing to continue processing your information for our legitimate interests or to comply with a legal obligation. We may request you provide us with information necessary to confirm your identity before responding to your request.
To exercise any of these rights, please contact us as described in the “How to Contact Us” section below. In addition to those rights, you have the right to lodge a complaint with the relevant supervisory authority. However, we encourage you to contact us first, and we will do our very best to resolve your concern.
Our Services are operated in the United States. If you are located outside of the United States, please be aware that any information you provide to us will be transferred to and/or accessed within the United States. The recipients of information described in the relevant "How We Share Information" sections above may be located in the United States. This information may be subject to United States law, including laws that may require disclosure of personal information to government authorities.
European Union-United States and Swiss-United States Privacy Shield: Piazza has certified with the E.U.-U.S. and Swiss-U.S. Privacy Shield as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of “personal data” (as defined under the Privacy Shield principles) from applicable European countries. We have certified that we adhere to the Privacy Shield Principles of notice, choice, purpose limitation, onward transfer, security, data integrity, access, recourse, liability, and enforcement for such personal data. To learn more about the Privacy Shield Framework, visit the Department of Commerce’s Privacy Shield list by clicking here.
As required under the principles, when Piazza receives personal data under the Privacy Shield and then transfers it to a third-party service provider acting as an agent on our behalf, we have certain liability under the Privacy Shield if both (i) the agent processes the information in a manner inconsistent with the Privacy Shield; and (ii) Piazza is responsible for the event giving rise to the damage.
Some international users (including those whose information we collect under the Privacy Shield) of our Services have certain legal rights to access certain information we hold about them and to request its deletion. Please see the “Your Choices” section above for more information.
Dispute Resolution for E.U. and Swiss Residents: If you are a resident of the European Union or Switzerland and are dissatisfied with the manner in which we have addressed your concerns, you may seek further assistance, at no cost to you, from our designated Privacy Shield independent recourse mechanism, the JAMS Privacy Shield Program, which you can learn more about by visiting here. Residents of the European Union or Switzerland may elect to arbitrate unresolved complaints but prior to initiating such arbitration, you must: (1) afford us the opportunity to resolve the issue; (2) seek assistance via Piazza’s recourse mechanism above; and (3) contact the U.S. Department of Commerce (either directly or through a European Data Protection Authority) and afford the Department of Commerce time to attempt to resolve the issue. Each party shall be responsible for its own attorney’s fees. Please be advised that, pursuant to the Privacy Shield, the arbitrator(s) may only impose individual-specific, non-monetary, equitable relief necessary to remedy any violation of the Privacy Shield Principles with respect to the individual. Piazza is subject to the investigatory and enforcement powers of the U.S. Federal Trade Commission (FTC).

The Services are intended for general audiences and not for children under the age of 13. If we become aware that we have inadvertently collected “personal information” (as defined by the United States Children’s Online Privacy Protection Act) from children under the age of 13, children under the age of 14 in Spain or South Korea, or from an EU resident under the age of 16 without parental consent, we will take reasonable steps to delete it as soon as possible. We also comply with other age restrictions and requirements in accordance with applicable local laws.
California law permits users who are California residents to request and obtain from us once a year, free of charge, a list of the third parties to whom we have disclosed their personally identifiable information (if any, and as defined by California law) for their direct marketing purposes in the prior calendar year, as well as the types of personally identifiable information disclosed to those parties. Piazza does not share your personally identifiable information with third parties for their own direct marketing purposes without your consent.
