Privacy Policy

We are committed to creating a safe and secure environment for learners of all ages on our websites located at,,,,,, other websites, application programming interface (our “API”), and online services (collectively, our “Website”). Visitors and users of the Website and participants in our education programs are referred to individually as “User” and collectively as “Users”. Any User that creates a student account is referred to as “Student” even if they are using the Website outside of a school setting. Similarly, any User that creates a teacher account is referred to as “Teacher.” As a not-for-profit, 501(c)(3) organization, we use the data we receive only insofar as it helps our mission of providing a great computer science education for every student in every school. We established ourselves as a not-for-profit organization so that a for-profit motive will not interfere with our mission of providing a trusted educational resource.

Our Privacy Policy describes what information we gather from our Users, how we use that information, and what we do to protect it. Your use of the Website and any information you provide on the Website are subject to the terms of this Privacy Policy, which is incorporated into and subject to our Terms of Service.

By visiting or using our Website, you expressly consent to the information handling practices described in this Privacy Policy.

Collection and Use of Your Information

The sections below describe the ways collects and uses personal data, which refers to any information that identifies you as an individual (directly or indirectly). This includes things like the name, display name, email address, school name and address, telephone number, etc. from Users (“Personal Information”), persistent cookies or IP addresses (“Persistent Identifiers”), as well as some of the non-Personal Information and technical information (described below) we collect. We collectively refer to any of this data we collect from Students, along with any Student information, Student records, and Student-generated content as “Student Data.”

Our collection, use, and disclosure of Student Data are governed by our Privacy Policy and Terms of Use, and where applicable, also by the provisions of the Family Educational Rights and Privacy Act (FERPA), the Children's Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR), and other applicable federal and state laws that relate to the collection of Student Data, including California’s Student Online Personal Information Protection Act (SOPIPA) and similar state laws. In addition, where we have entered into separate agreements with applicable local education authorities, such as our Student Data Privacy Addendum, the terms of those agreements may also govern our processing of Student Data. shall not use Student Data for any purposes other than those authorized pursuant to our Terms of Service, Privacy Policy, and any applicable agreement.

The Hour of Code: does not collect any Personal Information from students participating in the Hour of Code unless they choose to create accounts. The Hour of Code tutorials do not require login to use. accounts: The following table describes the data that collects from registered Users of courses. You can also try courses without creating an account, but your learning progress won't be saved.

Data stored by if you create a Student account How and when is the data collected? How this data is used
Display Name (e.g., “Cool Coder” or “John”) and username (eg "coolcoder7") Required by User (or their Teacher) on account creation Display name is used to provide Students a welcoming login and to identify the Student in the Teacher’s view of student progress. We recommend using first names only to increase privacy.

Usernames are generated based on the display name and can be used to sign into an account. Students have the option to update the username when creating a personal login that uses usernames.
Age (Not birthdate) Required by User (or their Teacher) on account creation or first sign in before using the site. This data is used to understand the developmental stage of Students in order to offer an age-appropriate experience for each Student. We use this field to ensure we don’t allow Students under age 13 to access age-restricted features (such as sharing their coding projects on social media). We store ages (e.g., 16), as opposed to birth dates (e.g., Feb 13, 2001).
One-way hash of student email address (NOT the actual email address, which is collected in the web browser but never transmitted to and thus never stored by us) Email address is required (but not stored) on account creation if Student signs up directly. Email address is not required if account is created by teacher, though can be optionally added by the Student later. A Student's email address is only used for the purposes of login. It is NOT stored by in a retrievable format. To protect Student privacy, we only store a one-way hash of the email address. We do not have any way of sending email to Students or retrieving their actual email addresses. See section on "Student Email Addresses" below for more details.
Parent or guardian email address Can be optionally provided by parent to receive updates or create a login for their child at home. Parents can choose to link their email address to their child’s account to receive updates from

A Student may want to create a personal login to access their account independently of their Teacher or school, especially if the Teacher decides to delete the classroom section that the Student belonged to or the Student signs in with a school-sponsored account like Google, Microsoft, Clever, or PowerSchool.

If the Student is under 13 or doesn’t have a personal email address and wants to create a personal login, we require a parent email address for password recovery. The Student will then be able to sign in at home with a username and password.
Login time, IP address, and other technical data Automatically collected as the site is used. This data helps troubleshoot any problems Users experience. It also helps understand usage patterns, ensure the service can support all Users, and enable site updates with minimal service disruption. See section below on “technical information” for additional details.
Gender Optionally provided by the Student or their Teacher. This information is only used in aggregate to measure the percentage of students that are male or female or to measure how male or female Students respond to different computer science challenges, or to track our progress towards reducing the gender gap in computer science.
Race Optionally provided by the Student or their Teacher (only requested from Students if their IP address is in the US). Students aged 13 and over have an option to indicate their race. For Students under age 13 we do not ask individual race, but we ask the Teacher to optionally estimate the racial distribution of the entire classroom.

This information is only used in aggregate, to measure the percentage of students from underrepresented racial and ethnic groups and their aggregate response to computer science challenges, in order to track our progress toward improving diversity in computer science.
Progress in the course
1- Date/Time each lesson is tried
2- Number of tries to solve a level, and whether it was solved successfully or optimally
3- Information on how the Student solved the level including time to completion and whether they used hints
4- The code that the Student submitted
5- Student-provided answers to simple assessments (e.g., multiple-choice questions)
Collected as Students work through a tutorial or course progression. This information is displayed to Students and their Teachers to see their progress in a course, to see the code they’ve created, and to identify topics they need help with. It also lets Students pick up where they left off if they sign out and sign in later. See example progress report, and see section below on “technical information” for additional details.

This data, in de-identified form, also helps improve course effectiveness. For example, if a level is too hard, may take action (like providing better hints) to improve the learning process.
Student projects - apps, animations, stories, or code-art Collected as Students create such projects. Creating apps and projects is part of our course progressions but can also be done outside our courses through our standalone tools. The code and underlying assets for these apps are stored by, so that Students can retrieve their projects each time they log in.

When Students work in the context of a classroom, their Teacher also has access to view the projects created by any Students in the classroom.

Student projects and code creations each have a custom URL that Students can use to share with others, or post to the public gallery. On the public gallery, projects are displayed with only the first letter of the Student’s display name to protect Student privacy as well as their age. We do not allow Students under the age of 13 to share App Lab, Game Lab, and Web Lab projects to the public gallery as these projects allow for Student-uploaded content.

Students may “remix” (copy, change, or improve upon) projects made by themselves or by other Users.

Students over age 13 can also, at their discretion, post their projects to social media.

In our elementary school courses, Students create stories, games, or art using tools, such as Play Lab, which are limited to using artwork and sounds provided by Students can write dialogues for these projects. Text provided by Students in these tools is automatically analyzed to help prevent sharing any email addresses, phone numbers, or street addresses.

Our middle school and high school courses teach Students to make more complex apps and games. These tools allow the Students to upload custom photos, sounds and/or videos. (See below)
Student-uploaded images, sounds, or videos (for App Lab, Game Lab, and Web Lab Projects) Collected if Students choose to upload custom files. Creating apps with these programming tools is part of our courses for grades 6+. Only Students of age 13 and older, or Students under 13 who are working in a classroom whose Teacher has explicitly accepted the Privacy Policy and Terms of Service, can choose to upload custom images, sounds, and videos to the platform to use within apps or games that they create. Students under 13 will be advised never to upload any media containing Personal Information.

These files are not used by for any purpose other than within these projects. These projects may be shared and remixed as described above, subject to those restrictions imposed on Students under 13.
Data collected by Student-created apps Collected if users of a code project created by the Student choose to enter data into the app. Students may use to create their own apps. Depending on the app author’s design, a Student-created app may in turn collect data by prompting other Users (anybody who tries using the Student-created app) to enter information, such as a favorite movie.

If a Student creates an app that collects and stores data in this fashion, all data entered by Users of the app may be accessed and possibly shared publicly by the app author, the app itself, and potentially anybody with a link to view the app. does not itself use or share this data outside of the app.

Before using a Student-created app that collects data, Users are shown a clear warning that any data they enter may be shared publicly and that they should not share anything personal to them or to others.
Written comments in response to curricular/educational prompts within courses Collected if Student chooses to enter text in response to the prompts. Within some of our courses, Students in a classroom are prompted to answer a question. Their answers are shared with any Teacher with whom the Student is affiliated on and are used by in de-identified form to improve the curriculum.
Student-provided responses to surveys (e.g., multiple choice and free response questions) Collected if Student chooses to fill out survey offered inside the courses. We may ask for responses to attitudinal questions (to assist the Teacher in understanding their classroom’s reaction to learning computer science and, in de-identified form, to help improve our curriculum). Students are informed that answers to these attitudinal questions are shared with the Teacher anonymously without their name attached. We may, however, share a Student’s identity, answer, and other information related to a given question with their teacher or appropriate authorities if we are prompted to do so, and upon investigation, we have a good-faith and reasonable belief that the answer indicates the Student may harm themselves or others, among a few other limited scenarios outlined in the section titled “How We Share or Transfer Data.” However, we are not monitoring student answers for such issues. If you are a teacher, please contact so we can help you if your Student indicates they may be unsafe.

Additional* data stored by if you create a Teacher account How and when is the data collected? How this data is used
Email address Email address is required on account creation (or when switching from a Student account to a Teacher account). Email addresses are used to send emails to the Teacher with updates about their classroom or Student progress, send notices when new course-work is available, and provide updates on curriculum, tools, professional learning options, etc.

All non-transactional emails sent by contain an unsubscribe link and do not require typing a password to unsubscribe.
District and school name and/or school type (private, public, charter, homeschool, after school, or other) and/or school address Optionally provided by the Teacher on account creation or after creating an account. At the Teacher's option and under their control, we would list their school in the map and database of schools that teach computer science courses. or our professional development partners** may also use this information to reach out to the Teacher's school or district to discuss broader education partnerships or participation in special events.
Student section data Collected if Teacher decides to create a section on to manage their Students. The Teacher may create accounts for their students (and provide each Student’s display name and optionally their age and gender), and organize these Students into sections. The Teacher may assign each section a display name, a course assignment, and grade level. The section grouping data is used to simplify their view of Students across multiple sections.

Teachers are encouraged to share a document with Students and parents informing them about the course, including the privacy implications.
Survey and demographic data Collected if teacher chooses to optionally fill out survey. For the purposes of evaluating our own work and improving our education results, regularly sends surveys to Teachers.

These surveys are completely optional. The data provided by Teachers in these surveys is saved and used for analysis by, our Evaluator, our Regional Partners, our International Partners, or facilitators. Any survey data shared with external parties will be de-identified and aggregated.
Attendance at professional learning workshops Collected when Teachers attend a workshop. Attendance of Teachers at our professional learning workshops is stored and associated with the Teacher’s account on

This data may be shared (along with the Teacher’s identity) with any other parties involved in the Teacher’s professional learning, such as the in-person facilitator who led the workshop, or the professional learning organization hosting the workshop, or the school district of the Teacher. In some cases, the school district may use the workshop attendance data to compensate Teachers for participating in the professional learning program.
Progress, answers, documents, projects, and peer reviews for online professional learning. Collected as teachers interact with our online professional learning tools.

Participation in professional learning programs is optional.
Progress and answers in online professional-learning courses for Teachers are stored in their Teacher account in order to allow Teachers to pick up where they left off.

This includes the lesson plans, documents, and other projects Teachers create as part of finishing the online learning courses. After submitting a document or project, Teachers receive peer feedback from each other which is also stored so that they can read it.

Teachers also take a self-assessment survey to create a custom learning plan. The results of this survey are stored with the Teacher’s account along with their custom plan.
Comment feedback provided to students Collected if Teacher decides to give written comments to their Students on their work The Teacher may provide written feedback to their Students on their coursework. Though a Student will only see the most recently provided comment on a given level, we store all the previously shared comments as part of the Teacher’s account in case the Teacher or school needs to access them later.

* A Teacher account on has all the functionality of a Student account, and as a result the data collected and stored for a Teacher account is a superset of the data stored for a Student account.

** partners with U.S.-based nonprofit professional learning organizations, our “Regional Partners,” as well as similar organizations outside the U.S., our "International Partners", collectively our "Local Partners". We share limited information (as outlined in this privacy policy, and never including Student Personal Information) with these partners to allow them to run local professional development workshops and support teachers and schools in their region. Each Local Partner signs an Agreement with that requires them to comply with this privacy policy and to treat any information received through the partnership as confidential.

Students and Teachers may update, correct, or delete Personal Information in their accounts at any time via the account settings page. Teachers can go to their section’s “Manage Students” tab to update the most common settings or to access a Student’s login information. Teachers also have the ability to reset the password of any Student in their section. A parent or legal guardian of a Student under the age of 18 may also review Personal Information and correct erroneous information, if any, by asking the Student or Teacher to access the Student account.

Teachers can create accounts on behalf of Students. When registering an account for a Student who is under the age of 13 (a “Child”), the Teacher represents and warrants that they or the educational organization they work for has proper permission to register the Child for, and that they or the educational organization has obtained the necessary parental consent for collection of some of the Child’s Personal Information for the use and benefit of the school and for no other commercial purpose. In addition, they agree to be bound by this Privacy Policy on behalf of the educational organization they work for, and are authorized to do so.

Student Data of any Student that is in a Teacher's section will continue to be under the control of the Teacher. If a Student over the age of 13 or a parent of a Student of any age attaches a personal email login to a Student account, the Student can add or remove themselves from a Teacher's section. Users over the age of 13 who use email or a third-party login such as Clever, Google Account or Microsoft Account can also add or remove themselves from as many sections as they want (unless the section is synced with Google Classroom or Clever). The Teachers for these sections get access to the User's course progress and display name, but not their email address. If a Student is no longer associated with a Teacher’s section, that means the Student Data will no longer be managed by the school or Teacher and the Student may retain possession and control of the Student-generated content.

In order to allow Users to recover deleted accounts, we will save progress, code creations and data for a period of time. A User can email to request permanent deletion of their account and all the associated data. A Teacher may also request the deletion of Student accounts or particular Student projects or Student Data the same way. Deleting a Student’s project will not delete other Students’ creations that were previously remixed from the deleted project.

Information from Third Party Authentication Services

If you decide to register for a account through an Authentication Service (such as Google Accounts, Microsoft Accounts, Facebook Connect, Clever, or PowerSchool), you give the permission to store and use information already associated with your Authentication Service consistent with this Privacy Policy and the table above.

When using third-party authentication systems, may receive personal data (such as a Student's full name or gender) that is not required for use of the Website. For example, districts or schools that use Clever as an Authentication Service can permit to use existing Clever teacher and student account information to sign in to sites. Districts or schools may revoke’s access to this information in Clever at any time.

You may revoke’s access to your account on any Authentication Service at any time by updating the appropriate settings in the account preferences of the respective Authentication Service. You should check your privacy settings on each Authentication Service to understand and change the information sent to us through each Authentication Service. Please review each Authentication Service’s terms of use and privacy policies carefully before using their services and connecting to our Website.

The information is used to enable your participation in the relevant feature and to send you occasional emails with information about that we feel may interest you. All non-transactional emails we send include an “unsubscribe” link. The one exception to this paragraph is when a User under the age of 16 signs our online petition supporting’s mission, any name or email address they provide is deleted from our servers and thus never used.

If you enter your name to print a certificate of completion upon finishing our courses, we save the name you enter in order to let you share your certificate digitally.

We may also survey Users to provide us with optional demographic information (such as gender, age, ethnicity), which we use in aggregate to better understand our User base.

Computer science educators may provide a school or classroom street address, along with a description of course offerings, in order to allow students or parents to find local schools, summer-camps, or workshops that teach computer science in their neighborhood.

If you nominate a teacher for professional development or to receive teaching resources, we will only send them emails about the program they are nominated for - they will not be added to any mailing lists (unless they sign up). The nominated teacher may see your name and your description of why you nominated them. Additionally, in the US, we will share the nominated teacher’s name, school, city, and why you nominated them (but not the teacher’s email address or your name) with our Regional Partner in the teacher’s state, so that our partner knows the teacher was recommended and to help process the teacher's application for a scholarship to the partner’s local workshops.

Lastly, for teachers, educators, and partners who participate in our computer science training programs, we may ask for information that is required for compensating or acknowledging you for your work (such as a mailing address to send a check, the name of the school/district that employs you, or a tax form containing your social-security number for IRS reporting purposes).

We use the embedded YouTube player in Privacy Enhanced Mode to deliver computer science videos within our curriculum. This means that YouTube does not place cookies or track your viewing behavior for advertising purposes. Our student-facing curriculum does not embed any YouTube videos that are not part of our curriculum. We have disabled the “rel” functionality of YouTube, which prevents the embedded YouTube player from playing related content outside of our curriculum. We have also tagged our “YouTube” videos on the site for “child-directed treatment”. Schools can choose to block access to YouTube, in which case we use a fallback option that plays videos directly from our Website. We also offer clearly marked links to visit Facebook or Twitter to share various things such as your creations or certificates on Using an account on these third-party social networking services is entirely at your option and under your control, and will not result in behavioral tracking of your browsing behavior on However, because we know that these services use behavioral targeting as part of their advertising business model, on student-facing course and activity pages, we don’t offer links to these services to Students under the age of 13, or in schools that have blocked Internet access to these services. (To opt out of various forms of internet advertising by third parties, you may visit the following links: or If you use these tools, you may need to opt out separately for each of your devices and for each web browser on each device.)

Uploading Custom Content

Student and Teacher profiles can NOT be customized with a photo.

As part of “App Lab,” “Game Lab,” or "Web Lab" (in-browser programming tools available on, Users 13 years of age and older as well as Students under the age of 13 in a classroom managed by a Teacher can upload custom images, text, sound, and videos to the platform to use within applications or “apps” that they create. These files are stored by, and are not used by for any purpose other than within the applications created by Users.

Message Sending Between Users has created a tool called the “Internet Simulator” for use in High School classrooms to model how the Internet functions. With this tool, Students participating in a Teacher-supervised classroom activity can send text-based messages to their Teacher and to other Students in their specific classroom section. Message contents are visible to the classroom Teacher and are not accessed or used by for any purpose other than in this educational tool. All messages are deleted after two hours of class inactivity, or upon a manual reset by the Teacher.

In some courses, Students are asked to provide written responses or reflections to prompts within courses. These written responses are accessible by any Teacher that the Student is currently affiliated with on

In addition, Users may send messages to for customer-support requests.

Other than the above, the Website supports no other form of messaging among Users.

Testing and Staging websites

For the purposes of testing our Website and services before releasing them into production for broad usage, we run staging and testing versions of our services for internal testing purposes only. These are meant only for experimental use by employees, contractors, or agents, and not considered part of the Website as defined in this agreement. Any information, including Personal Information or Persistent Identifiers provided while using these staging or testing versions of our services is not governed by this Privacy Policy.

Information We Do NOT Collect does not directly collect or store payment instruments. Donations to or purchases from the store are processed via third parties, and although receives a receipt for donations (for tax purposes), we never receive the payment instrument (such as credit card or wallet information).

Student Email Addresses

When User accounts use a Student email address for login, does not store the email address provided by those Users in a retrievable format. Instead, we immediately create and store only a one-way hashed version of the email address (which cannot be converted back into the original address), and use it only for the purposes of login, account management, and password recovery. In fact, when creating or signing into a Student account, the actual account email address is never even transmitted to's servers. The only circumstance when's servers receive a Student's email address is if the Student forgets their password and asks to reset it. At that point, the Student is prompted to enter their email, which is used to send them a password reset link.


If a User contacts us via our customer support pages, we will store and use their email address in order to respond to them. If a User aged 16 or over signs our online petitions, or a User creates a Teacher account on or offers to help us as a software industry volunteer, we will store and use their email address just as we do for other advocates of our nonprofit mission.

For a small minority of our Students, and only if they are over the age of 18, we may offer the opportunity to participate in a "longitudinal" study to understand the multi-year impact of learning computer science. Participation in such a study would be entirely optional. Students who receive an offer and choose to participate will be asked to provide their contact information (email address and optionally other forms of contact that may be more convenient for the Student). This contact information will not be shared with third parties, nor used in any way outside the purpose of such a study – to ask Students to participate in surveys. If we learn that we have inadvertently collected this information from a Student under 18, we will delete such information immediately.

Children Under Age 13 courses are designed to be used by Users of all ages, including children under the age of 13 with the involvement of and pre-authorization by their school, teacher, parent or legal guardian. In order to use features that involve uploading custom media files or sending messages within the school, we obtain prior consent from the Student’s teacher, other authorized school representative, or, in some cases, the parent or legal guardian.

When children under the age of 16 attempt to sign our online petition supporting’s mission, the email addresses and names are discarded and are not stored on our server.

If learns that it has inadvertently collected Personal Information or Persistent Identifiers from children under the age of 13 without prior parental or teacher consent, will take appropriate steps to delete this information. If you are a teacher, parent or legal guardian of a Student on, you can ask us to deactivate the Student’s account, delete any hashed email address or inadvertently collected Personal Information or Persistent Identifiers, and request that we no longer allow the Student to submit their information to To make such a request, please contact us at Before processing your request, we may verify your identity and your relationship with the Student.

Student Academic Data from School Districts

As is common in education research, to measure how well our programs perform and how well students are learning from them, engages experienced independent third parties (“Evaluators”) to do a thorough evaluation of our work in select partner school districts.

If a district chooses to participate in an evaluation, the school district is asked to provide student academic or demographic data from education records directly to the Evaluator, and they are only authorized to provide data that has been completely de-identified. The data enables the Evaluators to perform an independent study about our work, in compliance with all applicable Federal and local laws respecting student privacy. Neither nor the Evaluators will know the personal identity of individual students. When it comes to student assessments and academic results, will only allow districts to provide the Evaluators de-identified data, which will then be aggregated by the Evaluators across thousands of students from hundreds of schools to publish an independent study.
