Facebook (Privacy Policy)

Instagram (Privacy Policy)

We process data about your activities on our side, such as visits, publication of content (for instance text, images and videos) and reactions to our or others' content (for instance likes and comments) to administrate the page.

3.7 Measure Traffic on Our Web Page to Optimize Our Services

We use cookies on our web pages. Cookies are primarily used to measure traffic on our web page, so that we can optimize our services.

You can manage cookies through our cookie consent banner. Read more about our use of cookies here.

4. To Whom Do We Share This Data?

We will only share your personal data with others if they supply services in operation, maintenance, technical solutions or other necessary services for us. To ensure your rights, we have entered into an agreement with them that shall protect your privacy. This means, for example, that your personal data shall not be used for anything other than what is stated in this privacy policy. We will also not hand over your personal data to others unless it is in accordance with current rules and regulations. For example, it may be that you have given us permission to such sharing, or that we must hand over information in order to supply you with the services. We do not sell your personal data.

Some of our suppliers may be in countries outside of the EU/EEA. That means that personal data can be transferred to a country with laws that do not give the same level of protection of personal data as the laws of Norway. To ensure your privacy, such a transfer will only occur in accordance with the current privacy regulations, for example by us entering into the EU's Standard Contractual Clauses with the supplier or, where the supplier is certified, relying on the EU–U.S. Data Privacy Framework.

If you choose to create an account or log in via your Facebook account, we will share information about your use of our webpage with Facebook. Facebook's use of this personal data is regulated by Facebook's terms and conditions, which are available here. This entails a transfer of personal data to the US based on the EU's standard agreement.

5. Deletion of Personal Data

We delete personal data in accordance with our deletion routines. That means that we delete information about you when we no longer need it to offer you our services, for example if you delete your account. You can in some instances yourself request the deletion of your personal data. For more information, see Section 6 below. For School Users, the deletion commitments in Section 9 apply.

6. Your Rights

Request us to gather all information we have about you and send you a copy of it. You can also request an explanation from us about how we use your personal data.

7. Privacy Rights for U.S. State Residents

This Section applies to you to the extent a U.S. state privacy law — such as the California Consumer Privacy Act as amended by the California Privacy Rights Act (CCPA/CPRA), the Virginia Consumer Data Protection Act (VCDPA), or a similar law of another U.S. state — applies to our processing of your personal data.

Categories of personal information. In the last 12 months we have collected the categories of personal information described in Section 3: identifiers (such as name, nickname, e-mail address, account ID), customer records information (such as payment information processed by our payment provider), characteristics such as birth year and country, commercial information (such as subscriptions purchased), internet or other electronic network activity (such as usage of our services and, where enabled, cookie and pixel data), and inferences related to your learning progress. We collect this information from you directly, from your device, and from third parties such as Facebook if you use social login. We use it for the purposes described in Section 3 and disclose it to the service providers described in Section 4.

We do not sell personal information. Where our use of third-party advertising or analytics cookies is considered "sharing" of personal information for cross-context behavioral advertising under the CCPA/CPRA, you can opt out via our cookie consent banner, by enabling the Global Privacy Control (GPC) signal in your browser, or by contacting us at support@houseofmath.com. We do not sell or share the personal information of consumers we know to be under 16 years of age. We do not use or disclose sensitive personal information for purposes requiring a right to limit under the CCPA/CPRA.

Your rights. Subject to the applicable state law, you have the right to: know and access the personal information we hold about you; correct inaccurate personal information; delete your personal information; receive a portable copy of your personal information; opt out of the sale or sharing of personal information and of targeted advertising; and not receive discriminatory treatment for exercising these rights. Where required by your state's law, you may also appeal a refusal of your request.

How to exercise these rights. Contact us at support@houseofmath.com with the subject line "US Privacy Rights Request". We will verify your request using the e-mail address associated with your account and respond within the time required by the applicable law. You may use an authorized agent to submit a request on your behalf; we will require proof of the agent's authority.

8. Children's Privacy in the United States (COPPA)

Our consumer services are not directed to children under 13 in the United States outside of the settings described in this Section. In the United States, a child under 13 may use House of Math only:

through the child's school, where the school authorizes the use and consents to the collection of the student's personal information as described in Section 9; or

through an account created and managed for the child by a parent or legal guardian.

We do not knowingly permit children under 13 in the United States to create their own accounts directly. Parents and legal guardians may review the personal information collected in an account they manage, request its deletion, or refuse to permit further collection, by contacting support@houseofmath.com. If we learn that we have collected personal information from a child under 13 in the United States without the required consent, we will delete it promptly.

9. Special Provisions for U.S. K-12 Institutional Users

This section applies automatically to any account or use of House of Math in the context of a U.S. K-12 school, school district, or educational institution, and supersedes any conflicting language in these policies.

FERPA Compliance: House of Math operates as a "School Official" with a legitimate educational interest under FERPA (34 CFR § 99.31(a)(1)(i)). All student data and education records remain under the direct control and ownership of the school at all times.

COPPA Compliance: Pursuant to FTC guidance, House of Math relies on the school to act as the parent's agent to authorize data collection for students under 13 solely for educational purposes.

Data Restrictions & Security: We collect only basic identifiers (names, school emails, usernames, and progress data) necessary to run the platform. We explicitly do not collect personal contact info, phone numbers, or precise geolocation. Student data is never used for marketing, behavioral profiling, or advertising. Student progress, points, and achievements are never published on public leaderboards and are visible only within the student's own classroom or institutional environment. We encrypt data in transit and at rest.

Deletion & Breach Response: We will notify the school within 24 hours of an actual data breach. We will completely delete all student data within 30 days of a school's request or contract termination.

Dispute Resolution: Mandatory arbitration and class-action waivers do not apply to U.S. institutional K-12 accounts.

For inquiries or to exercise deletion rights, please contact schools@houseofmath.com.
