Effective date: July 1, 2023

VertexMathematics does not permit children under the age of 13 ("Child") to create an account and does not knowingly collect personally identifying information from children under the age of 13 without the consent and at the direction of a parent.

VertexMathematics permits Parents to set up child profiles associated with the Parent account so that children may access the Service under the Parent's supervision. We take special precautions to collect only as much information as is reasonably necessary for the child to use the Service and to ensure that Parents have access to and control of their child's use of the Service.

This Children's Privacy Policy applies to all users of child profiles associated with a Parent account, regardless of the age of the child.

By creating a child profile associated with a Parent account and permitting your child to use the VertexMathematics Service, you expressly agree to the practices described in this Children's Privacy Policy and you consent to the collection, use, and disclosure of your child's personal information as described herein.

1. How to create a child profile associated with a Parent account.

A parent must purchase a user license using a credit card on the Family Membership page, register for an account with VertexMathematics, and agree to the terms of our Terms of Service, Privacy Policy and this Children's Privacy Policy. During the account creation process, the Parent may create individual profiles for each child(ren) authorized by the Parent to use the Service through the Parent's account. Each child user profile must be associated with a Parent account, and children cannot access the Service without the Parent first signing in to the Parent account with the Parent's login credentials. After the Parent logs into a Parent account, the child user selects the child profile to use the Service.

2. What information does VertexMathematics collect from or about a child and how does VertexMathematics use this information?

Information you provide us. Through the Parent's account set-up, the Parent provides information about the child(ren) authorized by the Parent to use the Service through the Parent's account, including a profile name and selection of a profile avatar. We recommend that the Parent selects a profile name that does not include the real name or identifying characteristics of the child. The Parent may also create a "secret word," which functions similar to a password to access the child profile, though it cannot be used to sign in to the Service without the Parent first signing in to the Parent's account using the Parent's login credentials. VertexMathematics does not request a birthdate or any additional personal information from the user of the child profile, though the child may change his/her profile avatar, secret word and profile name (of course, the Parent will see these changes through the Parent's account dashboard).

VertexMathematics uses this information to provide the Service to the user of the child profile. VertexMathematics uses the e-mail address provided by users of Parent accounts to communicate messages about the account, such as subscription notices and password resets, and the child user reports and awards.

Information collected from the Child's use of the Service. During the course of providing the Service, we collect information about the user of the child profile's use of the Service and information submitted to the Service, such as answers to questions, for the purpose of providing feedback to the user and for compiling reports and awards.

When your Child accesses the Service through the Parent's account, we automatically collect and store usage information as well as information about the device used by the Parent and Child to access the Service. For example, we collect an IP address, location (at the city level), browser type, language preferences, and other information about the device used to access the Service, such as the device type, model and manufacturer and a unique identifier which allows us to uniquely identify your browser, device, or account, as well as account usage information such as the day/time stamp, referring/exit pages and URLs, pages viewed, and similar information. This information is typically collected through a variety of tracking technologies, including cookies, web beacons, log files, and similar technology (collectively, "tracking technologies"), and we may use third party providers to collect this information on our behalf. This data collection is explained in greater detail in Section 1 of our Privacy Policy under the sub-heading "Information we receive when you use the Service."

We use this information to secure and improve the Service, to provide personalized content and information, to remember you when you return to the Service at a later time or using a different device, to improve the Service, to save you time, to provide better technical support, to track website usage and other similar purposes.

3. How we disclose information

VertexMathematics may share or disclose a child's personal information as needed to provide our Service or with your consent or permission. For example, we share information with our trusted vendors, third party service providers and individuals to provide services for us on our behalf, which may include analytics providers and hosting services. We may also share personal information if we have a good faith belief that access, use, preservation, or disclosure of such information is reasonably necessary to (a) satisfy any applicable law, regulation, legal process, or enforceable governmental request; (b) enforce applicable Terms of Service, including investigation of potential violations thereof; (c) detect, prevent or otherwise address fraud, security or technical issues; (d) protect the rights, property, or personal safety of VertexMathematics, its users, or the public; or (e) as required or

Please note: This Children's Privacy Policy is designed to supplement the general Privacy Policy. If there is a conflict between the two policies, the terms of this Children's Privacy Policy will govern.

4. Third-party tracking and online advertising on the Service

VertexMathematics does not display any targeted advertising on the Service. We work with third-party online advertising networks which use tracking technologies (such as cookies, web beacons and similar technologies) to collect information about visitors to direct targeted advertising on other websites or services. We take certain steps designed to avoid these third-party tracking technologies from collecting information from users of Child profiles for targeted advertising purposes.

5. How to access and delete your child's personal information

The Parent may review the information collected from the user of the child profile at any time by signing in to the Parent account. The Parent may refuse to permit the further collection of the child user's information by no longer providing the child user access to the Service through the Parent's account.

VertexMathematics will retain the personal information collected from and about the user of the child profile for as long as necessary to provide the Service and will de-identify or delete the personal information after the termination of the Parent's subscription account in accordance with our standard data retention policy or until we receive a deletion request. To request deletion of personal information of a user of a child profile at any time, please contact us at compliance@vertexmathematics.com.

6. Our practices involving Schools

When VertexMathematics is used by a School in an educational setting, the School may authorize VertexMathematics to collect information from a child under 13. If you are a Parent whose child accesses the VertexMathematics Service through a School, please contact the child's School to request to access, review and/or delete your child's information. VertexMathematics will process such requests promptly as directed by the School.

7. Region-Specific Disclosures

We may choose or be required by law to provide different or additional disclosures relating to the processing of personal information about residents of certain countries, regions or states. Please refer to the Region-Specific Disclosures section of our Privacy Policy to learn more.
