The Hour of Code: does not collect any Personal Information from students participating in the Hour of Code. The Hour of Code tutorials do not require login to use.

Code Studio: The following table describes the data that collects from registered Users of the Code Studio tutorial platform. You can also try all Code Studio tutorials without creating an account, but your learning progress won't be saved.

Data stored by if you create a Code Studio student account Required? How this data is used
Display Name (eg “Cool Coder” or “JohnS”) Mandatory To provide students a welcome upon login, to identify the student in the teacher’s view of student progress, and when showcasing the student’s code-creations.
Progress in the course
1- Date/Time each stage is tried
2- Number of tries to solve a puzzle, and whether it was solved successfully or optimally
3- The code that the student submitted. (This includes art and games they create)
Mandatory (automatic) 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 log out and login later. See example progress report, and see section below on “technical information” for additional details.
Student code creations (art, animations, apps) may be shared with friends or to a public gallery at the discretion of the student, along with the students’ display name.
This data also helps improve the course effectiveness. For example, if a puzzle is too hard, may take action (like providing better hints) to improve the learning process.
Login time, IP address, and other technical data Mandatory (automatic) This data helps troubleshoot any problems users experience. It also helps understand usage patterns, to guide the build out of servers to support all users, and to enable updating the site while minimizing service disruption. See section below on “technical information” for additional details
Email Address Optional if account created by teacher or parent
Mandatory if student signs up directly
Mandatory for teacher or parent accounts
To inform the student or parent or teacher when new course-work is available and updates on curriculum, tools, professional learning options, etc. All emails contain an unsubscribe link. The student’s email address is optional when a teacher or parent creates a student account. If a student creates an account directly, an email address is required, to enable to help the student User retrieve their forgotten password.
If provided, the email can be used by the student as their login username and unique identity.
If provided, the student email address is private and not shared with anyone (not even the teacher)
Note: See section below for details on how we handle email addresses from children under 13.
Gender Optional This information is only used in aggregate, to measure the total % of students that are male or female, to track our progress towards reducing the gender gap in computer science.
Age (Not birthdate) Mandatory To understand the developmental stage of students to offer an age-appropriate experience for each student. We use this field to ensure we don’t store email information for students with age < 13. We collect ages (eg 16), as opposed to birthdates (eg Feb 13, 1998)
Any phone number Optional Users aged 13 or older can choose to share their app, art, or other code creations to a phone. To do this, they are asked to provide a phone number (their own or someone else’s). uses a 3rd party service (Twilio) to send a pre-written text message to this number. does not store any record of the number, however the phone number and message will be stored by Twilio and may also be stored by the phone service provider.
Custom photos, sounds, and/or videos Optional Users aged 13 or older can choose to upload custom photos, sounds, and videos to the Code Studio platform to use within applications that they create. These files are not used by for any purpose other than within the applications created by such users.
Messages sent within the “Internet Simulator” Optional The “Internet Simulator” is a tool developed by for use in High School classrooms to model how the Internet functions. With this tool, students can send text-based messages to other students and the teacher in their specific classroom section only. Contents of messages sent by students using the tool can be accessed by the recipient, and are not accessed or used by for any purpose other than in this educational tool.
Written comments in response to curricular/educational prompts within the Code Studio platform Optional 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 Code Studio, and are not used by for any other purpose.

Additional data stored by if you create a Code Studio teacher account Required? How this data is used
School name Optional

School address Optional At your option and under your control, we would list your school (and relevant contact information, if you provide it) in the map and database of schools that teach computer science courses.
Student section data Required
You may create accounts for your students (and provide each student’s display name and optionally their age and gender), and organize these students into sections or groups. You may assign each section a display name, and a course assignment. The section grouping data is used to simplify your view of students across multiple sections.
Teachers are encouraged to share a document with students and parents informing them about the Code Studio course, including the privacy implications.

Students and teachers may update, correct, or delete Personal Information in their Code Studio profiles at any time via the account settings page (or the manage students page for teachers).

Educators can create accounts on behalf of students. When registering an account for a student who is under the age of 13 (a “Child”), the Educator represents and warrants that they or the educational organization they work for has proper permission to register the Child for educational services, such as, that collect some of the Child’s personal information for the use and benefit of the school and for no other commercial purpose.

If you are a parent or legal guardian you can ask us to deactivate your child’s account, delete any hashed email address or inadvertently collected Personal Information, and request that we no longer allow your child 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 child.

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 an experienced independent 3rd party, Outlier Research & Evaluation (“Evaluator”) to do a thorough evaluation of our work in select partner school districts. Outlier is part of the University of Chicago’s Center for Elementary Mathematics and Science Education. For information about Outlier’s experience and track record evaluating education initiatives and student data, visit

To participate in the evaluation, these school districts are asked 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 anonymized (removing student Personal Information such as name and address). The data enables the Evaluator to perform an independent study about our work, in compliance with all applicable Federal and local laws respecting student privacy. Neither nor the Evaluator will know the personal identity of individual students. When it comes to student assessments and academic results, will only allow districts to provide the Evaluator anonymized data, which will then be aggregated by the Evaluator across thousands of students from hundreds of schools to publish an independent study. Besides the anonymity of this student academic data, our contracts with school districts also specify very strict limits on who may access this data. You may read the template contractual language governing student-data in our district agreements at
