Privacy Policy

This Privacy Policy discloses the practices of Math Shelf, concerning information we obtain by and through your use of the Math Shelf website (the "Site"), the Math Shelf online services (the "Service") and/or the Math Shelf Mobile Application (the "Product"). Math Shelf is committed to respecting your privacy and recognizing your need for appropriate protection and management of Personally Identifiable Information you share with us. The purpose of this privacy policy is to explain the types of information Math Shelf obtains about visitors to our Site and users of our Product and Service, how the information is obtained, how it is used, and the choices you have regarding our use of, and your ability to review and correct, the information. By using the Site, the Service and/or the Product and by agreeing to Math Shelf's Site Terms of Use, you are accepting and consenting to the use of your information as described in this policy.

1. What Information We Collect

The information we collect on our Site and through the use of our Product generally falls into the following two categories: Personally Identifiable Information and Non-Personally Identifiable Information. If we do combine Non-Personally Identifiable Information with Personally Identifiable Information, the combined information will be treated as personal information for as long as it remains combined.

Personally Identifiable Information

Personally Identifiable Information refers to information that lets us know the specifics of who you are. The Personally Identifiable Information we collect when you use our Product may include the teacher's name, phone number, e-mail address, login name, passwords, etc. We request Personally Identifiable Information when you register for the Product.

Non-Personally Identifiable Information

Non-Personally Identifiable Information refers to information that does not by itself identify a specific individual. We collect Non-Personally Identifiable Information in the form of statistics and information regarding the Product's overall classroom, building, and organization use and performance statistics. This enables us to document the benefits of the Product in classrooms, schools and systemwide.

Information You Provide for Your Students

You need to register and create an account for the Product. When you register for the Product, you may be asked to provide certain information regarding your students who use the Product's educational games and activities. This information may include the child's first and last name. Providing this information will allow you to take full advantage of the diagnostic and monitoring tools offered through the Product. We do not collect Personally Identifiable Information directly from children and the information collected from use of the Product by children relates to game play and performance; your child will not be able to submit Personally Identifiable Information through the Product or the Service.

2. Why We Collect Information

Our primary goals in collecting information is to:

  • Provide you with the all features and functions of the Product,
  • Provide Users with superior service
  • Provide all visitors a smooth, efficient, and personalized learning experience while using the Product.

We may collect Non-Personally Identifiable Information on an aggregated and anonymous basis to analyze customer behavior and to help us iteratively improve our Product. We may also use information relating to use of the Product on an anonymous and aggregate basis for research purposes, and to develop new learning tools and solutions. If your information or your student's information is used for such purposes it will be used anonymously and will not be tied to your Personally Identifiable Information.

We may use Personally Identifiable Information to communicate with you about the Product.

3. How We Collect Information

We collect Personally Identifiable Information only when you provide it to us. Math Shelf does not solicit or collect personal information from children and use of the Product and Service by children results only in the collection/transmission of Non-Personally Identifiable Information to Math Shelf, such as game play scores and statistics. If you do not wish for your Personally Identifiable Information to be used or collected, please do not submit it to us. Whether or not you choose to provide such information is completely your own choice.

4. How We Use Information About You

Our primary use of student information is to adapt instruction to meet their learning needs. Student information is shared only with their teachers. We do not share any data with third parties. All data is encrypted on our servers and protected with SSL certificates. We may also use teacher's personal information to provide customer support and to respond to your requests in a timely fashion.

5. Where we store, and how we protect your data

Data is stored on Amazon Web Servers in the Pacific Northwest region of the United States of America. We use technological (data encryption and SSL certificates) and physical safeguards to protect Personally Identifiable Information you provide to us from loss, misuse and unauthorized access, disclosure, alteration and destruction. Additionally, we comply with Amazon Web Services data security measures outlined here:

No method of transmission over the Internet, however, is 100% secure. Therefore, while we strive to make all reasonable efforts to use commercially acceptable means to protect your personal information, we cannot guarantee its absolute security. In the unlikely event of a data breach, you will be notified within 24 hours. We urge you to keep any password for use of the Program in a safe place and not to divulge it to anyone.

6. How to Correct or Remove Personal Information

If you do not want your Personally Identifiable Information collected or stored, please do not submit it to us. If you have already submitted personal information and would like us to correct or remove your information from our records, please contact John Schacter (

7. Children's Online Privacy and Protection Act

Math Shelf does not knowingly collect personal information from children. Any information collected from use of the Product by children is strictly anonymous and any data we do collect is aggregated and anonymized. Any personal information submitted through the Program is collected from users (teachers, parents or guardians) over the age of 18. By using the Program, you represent that you are over the age of 18, that you are the teacher, parent or legal guardian of any child for whom you may submit information, that you consent to the collection and use of your (or your child's) information by Math Shelf consistent with this Policy, and that you consent to your child's use of the Product.

8. Disclosures to Third Parties

We do not share your information with third parties.

  • Special Circumstances: We may disclose your information, including Personally Identifiable Information, in the following special circumstances:
    • In response to a subpoena or similar investigative demand, a court order, or other request from a law enforcement or government agency; to establish or exercise our legal rights; to defend against legal claims; or as otherwise required by law;
    • When we believe disclosure is appropriate in connection with efforts to investigate, prevent, or take other action regarding illegal activity, suspected fraud or other wrongdoing; to protect and defend the rights, property or safety of our company, our users, our employees, or others; to comply with applicable law or cooperate with law enforcement; or to enforce our Site's terms and conditions or other agreements or policies.
    • In connection with a corporate transaction, such as the sale of all or a portion of our business, a divestiture, merger, consolidation, or asset sale, or in the event of bankruptcy. We will endeavor to contact you in the event of any of these transactions, but we do not promise to do so.

9. Data Disposal and Destruction

Three months after a Math Shelf license expires, we destroy all user data associated with that account. We employ assured data deletion methods that reflect everywhere data or copies of data exist including metadata, data from buffer, RAM or any service layer that uses the data. When destroying electronic data, we use appropriate data deletion methods to ensure the data cannot be recovered. Complete deletion means that data is removed from all layers and components that handle data. Deleted data is not accessible after deletion, either by Math Shelf or the end user. Data is completely wiped from Math Shelf's servers and from locally stored devices. Finally, we email users an acknowledgement after we've deleted their data to inform them that the data deletion has been completed successfully

10. Policy Changes

To improve the services it can offer you, Math Shelf may opt to expand its capabilities for obtaining information about users in the future. Math Shelf will update this privacy statement continually to ensure that you are aware of developments in this area. We will post those changes here so that you will always know what information we collect online on through our Product, how we use it, and what choices you have. Please be sure to check this page before proceeding to use our Product.
