You consent to the collection, use, and disclosure of your information in accordance with this Privacy Policy. If you do not agree with our policies and practices, please discontinue use of our Services immediately. By accessing and continuing to use our Services, you agree to the collection and use of information in accordance with this Privacy Policy.

3.USERS OF OUR SERVICES UNDER THE AGE OF 13
We are committed to compliance with the Children’s Online Privacy Protection Act (“COPPA”). Before collecting personal information from children under 13, we obtain verifiable parental consent through approved methods, such as credit card verification, signed consent forms, or direct video or phone communication.
If you are under the age of 13, you may only use the Services with verified parental consent.
If you are a parent or legal guardian who has agreed to be bound by this Privacy Policy on behalf of a child, you agree to be fully responsible for such child’s use of Mathmaji, including all financial charges and legal liability that such child may incur.
In addition to the other information we collect as disclosed in this Privacy Policy, we may collect information:
When a child creates an account.
We collect data on the learning status of the child, including the time spent on answering each question, whether the answer to each question is correct or incorrect, and the child’s progress for the purpose of personalizing learning and improving the Services.
We also collect a username and password from child account holders, which are used for login purposes only, to permit the child account holder to use the Application and Services.
When we are the processor. We may collect certain personal information from children through our products for parents or teachers/schools, but we do so in our capacity as a processor or on their direction.
We only collect as much information about a child as is reasonably necessary for the child to participate in the Services, and we do not condition his or her participation on the disclosure of more personal information than is reasonably necessary.
If we become aware that a person submitting information to us is under the age of 13 and has not obtained verified parental consent, we will delete the information as soon as we discover it and will not use it for any purpose nor disclose it to third parties. If you are a parent or guardian concerned that your child may have provided personal information to us without consent, please contact us as set forth in the “Contact Us” section below.
Parents or legal guardians who consent to their child’s use of the Services can review, correct, or request deletion of their child’s personal information by contacting us directly at privacy@mathmaji.com.

9.EXERCISING YOUR RIGHTS
To exercise any of your privacy rights, either:
Email Mathmaji at privacy@mathmaji.com.
Please include your email address, full name, and your specific information about your request(s) and, if applicable, specifically what information you do not want to receive.
If you would like to update or correct your email address, street address or other personal information with us, please include specific details about the information you wish to have updated or corrected.
If you are appealing a decision please provide information about the denied request.
OR
Write to Mathmaji with your request at 6900 Dallas Pkwy, Plano, TX 75024.
Mathmaji’s process to fulfil a privacy rights request:
First, we acknowledge your request.
Mathmaji will first send you a message acknowledging receipt of your request.
Next, we ensure that you are the person making the request.
In general, when you make a request Mathmaji will take steps to verify your identity.
Verification steps may include asking you for personal information, such as your name, address, or other information we maintain about you or your child.
If we are unable to verify your identity with the degree of certainty required, we will not be able to respond to the request. In that case, we will notify you to explain the basis of the denial.
Finally, we provide a response.
We will either honor your request or tell you why we denied it.
Your parent or agent can submit requests for you.
If you are the parent of a child whose information we have collected or are currently processing then you may submit requests on behalf of your child.
You may also designate an authorized agent to submit requests on your behalf.
If you do so, you will be required to verify your identity by providing us with certain personal information as described above.
Additionally, we will also require written proof the agent has permission to act on your behalf.
We will deny your request if the agent is unable to submit proof to us that you have authorized them to act on your behalf.
How long will it take?
Mathmaji will either fulfill or reject your request as soon as we can, generally within 45 days from when we receive your request (or less, if required by law).
But we may be allowed to take longer to process your request under certain circumstances.
We will let you know if we expect your request will take us longer than normal to fulfill.
What if my request is denied?
You may appeal your denial if you feel we have made a mistake.
To submit an appeal please use the same method of contact listed above.
If you are still not satisfied with our response then, under certain circumstances, you may contact your state privacy enforcement agency.
10.YOUR PRIVACY CHOICES
We strive to provide you with choices regarding the personal information you provide to us. We have created mechanisms to provide you with the following control over your information:
Messaging and newsletter communications. You may control how you receive certain types of communications by clicking the link to unsubscribe within the body of the communication. Note that some messages are required, service-related messages like transaction confirmation messages, legal notices, or updates. If you no longer wish to receive any communication from us and discontinue the use of our Services, you may delete your account and your personal information through your account settings within the Application.
Cookies and web tracking technologies.
What we use on the Services.
We use cookies and other embedded tracking technology like web beacons, and pixels which automatically collect users’ browsing information when they use our Website.
Third-Party cookies.
You will find other parties’ trackers on our Website. Other parties like our analytics and advertising partners place code with cookies or web beacons embedded in them. Some third-party cookies are used to track a particular user’s activity across the Internet.
Limiting Google’s tracking and data collection through cookies.
You may limit the automatic collection of information by Google, including the collection of personal information about your online activities over time and across third-party websites or online services, by opting-out of such collection. Download the opt-out browser extension, located here, to opt-out of the automatic collection of browsing and device data.
Opt out of cross-site and interest-based advertising.
First, this is not a universal opt-out request you submit to us.
Submitting a request to opt-out of cross-site advertising using the methods below is not the same as opting out of the way we use your personal information.
We do not receive your opt-out of cross-site advertising.
For more details on limiting how we use your information, see the section above regarding Your Privacy Rights.
What happens when I opt out of cross-site advertising?
When you opt out, your selection is stored on a cookie on your device.
If you delete the cookie from that device or sign in from a different device, you will need to opt out again.
Does opting out of cross-site advertising stop all data collection?
Because the data used for interest-based advertising is also used for other necessary purposes (including providing our Services, for authentication, and security purposes), opting out of interest-based advertising does not stop the data from being collected nor reduce the number of advertisements you will see.
However, the data will not be used for interest-based advertising, which means the advertisements you do see may be less relevant to you.
Is my mobile device included when I opt out of cross-site advertising?
When using a mobile application, you may receive interest-based in-application advertisements.
Depending on your device, you may be able to reset your mobile device’s advertising identifier at any time by accessing the privacy settings on your device.
In addition, each operating system (e.g., iOS for Apple devices, Android for Android devices and Windows for Microsoft devices) provides its own instructions on how to prevent the delivery of interest-based in-application advertisements.
You may review the support materials and/or the privacy settings for the respective operating system in order to opt-out of interest-based in-application advertisements.
For any other devices and/or operating systems, please visit the privacy settings for the applicable device or contact (or review the applicable privacy web page of) the applicable platform operator.
Limit the automatic collection of information by any participating third-party advertisers.
To submit your request to opt-out of that automatic collection of browsing data, visit:

Mathmaji may offer you certain discounts, free or exclusive products or services, or other rewards, such as rewards points, for participation in opt-in rewards points programs. If you are eligible and opt-in, these programs may be considered a financial incentive under the CCPA.
Participation in these programs is voluntary, and requires your prior consent. If you choose to participate, you may do so by becoming a registered customer.

Our Services may contain links to other websites including those that permit online transactions. Mathmaji does not endorse, approve, or certify these other websites, and we do not guarantee the accuracy, completeness, efficacy, or timeliness of the information contained on those websites.

13.LOCATION OF PROCESSING
Your personal information may be transferred to and processed by the recipients indicated in “How We Disclose Information to Others” section of this Privacy Policy. Some of these recipients may be located in a country outside the one where you reside, and which may not offer similar levels of data protection by law.
Those parties may be located both within and outside the European Union or European Economic Area, the United Kingdom, or Switzerland.
When your information is moved from your home country to another country, the laws and rules that protect your personal data in the country to which your information is transferred may be different from those in the country in which you live. For example, the circumstances in which law enforcement can access personal data may vary from country to country. In particular, if your information is in the United States, it may be accessed by government authorities in accordance with U.S. law.
Please be advised that information Mathmaji collects about you via the Services may be transferred, processed and/or accessed by us in the United States, or another country where we, or our service providers operate. Please be aware that the privacy laws and standards in certain countries, including the rights of authorities to access your personal data, may differ from those that apply in the country in which you reside. If you are located outside the United States and choose to allow us to collect information about you, please be aware that Mathmaji may transfer your personal data to the United States and process and store it there. We will transfer personal data only to those countries to which we are permitted by law to transfer personal data.
14.SECURITY AND YOUR ACCOUNT
Mathmaji will take steps to protect your personal information. We maintain physical, electronic and procedural safeguards to ensure that personal information is stored and processed responsibly. When we collect information, it is stored in an area to which the general public does not have access. We encrypt data in transit and encrypt passwords in storage.
However, no internet transmission is ever fully secure, and we cannot guarantee that information transmitted via our Website will remain confidential at all times.
In the event that any use of the Application involves log-in credentials, please bear in mind that anyone you provide with your log-in information will also have access to your account and personal information. If you create an account with log‐in credentials, you are responsible for maintaining the confidentiality of any log-in credentials associated with your account.
15.CHANGES TO PRIVACY POLICY
Mathmaji recognizes that information privacy is an ongoing responsibility, so we reserve the right to change this Privacy Policy from time to time by posting revisions on our Website. We will notify you when these changes occur in accordance with our Terms of Use. Updates to our Privacy Policy will occur when we modify or alter any of our data practices, such as using data for other purposes or disclosing data to other categories of parties not mentioned in this version of this Privacy Policy. Mathmaji will update the effective date of this Privacy Policy when changes are made, so please check this page periodically for changes.
If we make material changes affecting personal information collection or use for children under 13, we will provide direct notice to parents or guardians and obtain new consent as required by COPPA.

We will respond to any complaints from you and will provide consultation to anyone whose personal information is concerned as to the handling of his or her personal information. We will respond properly and promptly to any request for disclosure, correction, addition, deletion, refusal of use or provision regarding personal information.
