Plickers	Not Approved	Declined We received your request to have Plickers sign and return the California Student Data Privacy Agreement. While we truly appreciate the need for privacy around student data, we cannot respond to every single request we receive individually. However, our Privacy Policy is posted on our website. Here is the link: Plickers Privacy Policy. We are also fully GDPR compliant and have completed our Privacy Shield certification to further reinforce our commitment to all privacy matters. Please see the Privacy Shield website for more information. Additionally, we want to reinforce that Plickers definitely does not store images or video from your mobile device on our servers. When teachers scan student responses, the processing gets conducted locally on the mobile device. No images are ever stored or kept on the device beyond the initial "reading" or scanning; only the student answer choice is derived. We sincerely hope that this satisfies your school’s privacy requirements. Please feel free to contact us if you require additional information. School Year: Select One

Prodigy	Not Approved	Declined Thanks for contacting Prodigy Customer Support! Unfortunately, as a free product for schools, we currently don't have the legal resources to be able to properly review and sign individual agreements with schools, school districts, and other bodies that make use of our product. With this in mind, we are not currently able to sign on to any individual privacy agreements. I would however, point you to the following page that contains articles that lists our compliance with several pieces of federal and state legislation which also describe how we handle Personally identifiable information (PII): https://prodigygame.zendesk.com/hc/en-us/sections/201846096-Privacy I can assure you that we take our users' privacy and protection of their information very seriously. With this in mind we have worked with iKeepSafe to review and revise our privacy policy in order to ensure that we comply with the following pieces of legislation and have recognizable seals/badges to signify this: • Family Educational Rights and Privacy Act (FERPA) • The Children’s Online Privacy and Protection Act (COPPA) • Protection of Pupil Rights Amendment (PPRA) • Student Online Personal Information Protection Act (SOPIPA) • AB 1584: Privacy of Pupil Records: 3rd-Party Digital Storage and Education Software • Collection of Student Information from Social Media (California Education Code 49073.6 Pupil Records: Social Media) • The Health Insurance Portability and Accountability Act of 1996 Please have a look at our updated Privacy Policy here: https://www.prodigygame.com/privacy-policy/ Your concerns regarding privacy and the protection of student information are shared here at Prodigy and always have been. We hope that these documents demonstrate this clearly to you and all of our Prodigy users. Please let me know if you have any questions/concerns by responding to this email and I'll be happy to address them for you to the best of my ability.

Quill	Not Approved	Declined Thanks for reaching out! We take data privacy very seriously, and we never sell or trade student data. We follow all industry best practices to keep our data safe, including encryption and other safeguards. You can see our full privacy policy at https://www.quill.org/privacy We are unable to enter custom privacy agreements with our non-paying school users.

Our team thoroughly reads privacy agreements to ensure we can meet all criteria. However, these data requirements impose additional costs on our organization, and we are currently unable to provide those services for non-paying school users. Please let us know if you have any questions.

Scratch	Not Approved	Declined Thank you for reaching out to us regarding Scratch’s privacy practices. Scratch cares deeply about the privacy of students and of all individuals who use our platform. The Scratch Team has in place physical and electronic procedures to protect the information we collect on the Scratch website. We strictly limit individual access to the Scratch servers and the data we store on them. We encourage you to read our Privacy Policy for more information. Although we are not in a position to offer contractual guarantees with each entity that uses our free educational product, we are in compliance with all federal laws that are applicable to MIT, a 501(c)(3) organization and the entity that created and maintains Scratch. Additional information about Scratch’s policies and practices as outlined on our Terms of Use and Frequently Asked Questions pages. We have recently launched Scratch Teacher Accounts which may be of interest to you. Teacher Accounts allow educators to create student accounts without identifiable student information (such as student email addresses and student-created usernames). Learn more about Teacher Accounts here. In addition, you may be interested in the Scratch 2.0 offline editor, which is a stand-alone version of Scratch that runs offline. This allows students to create Scratch projects without creating online profiles, sharing data online, or using the online community. You can download the offline editor here. We hope that you will continue engaging young people in creative learning experiences using Scratch. Sincerely, Scratch Team School Year: Select One
