The user may terminate the modified Services within 45 days of submitting the new ToS.

1. Your responsibility for internet access

To use the Website, you must obtain access to the World Wide Web, either directly or through devices that access web-based content, and pay any service and/or telephony fees associated with such access.

You have obtained and shall maintain all consents, licenses, and necessary filings and settings for the Website and/or intellectual property rights related to any Services, to be available to you. You shall guarantee that the Services will not be used to violate any law, regulation, or rights of third parties, including intellectual property rights, or to incite or facilitate such a violation.

3. Prices

Happy Numbers provides free and paid licenses to use Teacher accounts, as our pricing page outlines. Teacher accounts allow you to use our exercises on an interactive whiteboard for group instruction and modeling. Individual student accounts are connected to Teacher accounts and might require a paid subscription depending on whether the Teacher account needs one. If you have any questions regarding our pricing, please contact us at: support@happynumbers.com.

4. Supervising children

Happy Numbers is concerned about the safety and privacy of all its users, particularly children. For this reason, children should be assisted by their parents, legal representatives, or teachers to access the Services by helping them set up any relevant accounts and supervising their access to the Website and the Services. Happy Numbers agrees that students’ personally identifiable information stays under the parents’ and school’s direct control.

If you are a teacher, you represent and warrant, and Happy Numbers assumes that you have the express consent of the children’s parents or legal representatives to use the Services.

Suppose a parent or a legal representative becomes aware that their represented minor has registered with us without express authorization. In that case, they should contact us using the information at the end of this page. We will delete such accounts from our files within five working days.

Happy Numbers warns persons holding parental authority, legal representatives, or teachers about the diversity and the nature of the content available on the internet, which might harm minors. So, parents, legal representatives, and teachers are encouraged to monitor children when they connect to the Website. Parents, legal representatives, and teachers shall determine what Services available on the Website minor children are allowed to use and monitor the use of the Services by the minor.

5. Indemnity

You agree to indemnify and hold Happy Numbers and its subsidiaries, affiliates, licensors, licensees, officers, agents, co-branders and other partners, and employees harmless from any liabilities, losses, damages, claims, penalties, fines, costs, and expenses, including without limitation reasonable legal fees, that may arise in connection with: (i) your use of and access to the Website and Services, including without limitation any text, logo, graphic, image, video, music, or any multimedia file (the “Content”), as well as your connection to the Website; (ii) your, your children's, or third party's failure to comply with any provision of the ToS; or (iii) any claim by a third party that any other use of the Website by you or your children infringes any intellectual property, other proprietary or privacy right of such third party or has otherwise caused damage to a third party.
