The following terms and conditions ("Terms of Use" or “Terms”)) govern your access to and use of our products and services, including any content, functionality, and services offered on or through Aristotle (the "App") or any related applications, including mobile applications (collectively with the App, the "Services"), whether as a guest or a registered user.
Please read the Terms carefully before you start to use the Services, as they include important provisions
regarding your use of the Services, including solving disputes through
arbitration.
By using, registering for, or accessing the
Services, you accept and agree to be bound and abide by these Terms of Use and our Privacy Policy
(“Privacy Policy”), incorporated herein by reference.
If you do not want to agree to these Terms of Use or the Privacy Policy, you must not access or use the Services.
Our Services are intended for individuals aged 13 years or older. By accessing or using the Service, including this App, you represent and warrant that:
If you are a parent or guardian and you believe that your child under the age of 13 has provided us with personal information without your consent, please contact us at privacy@harmonic.fun, and we will take appropriate steps to delete such information in accordance with our Privacy Policy.
We do not knowingly collect personal data from children under 13. If we become aware that a child under 13 has provided us with personal information, we will promptly delete it in compliance with the Children’s Online Privacy Protection Act (COPPA).
We may revise and update these Terms of Use from time to time in our sole discretion. All changes are effective immediately when we post them, and apply to all access to and use of the Services thereafter. However, any changes to the dispute resolution provisions set out in Third-Party Platforms (Apple and Google)
If you access the Services via a mobile application downloaded from the Apple App Store or Google Play Store (“App Providers”), the following terms apply:

The App Providers are not responsible for providing any maintenance or support services for the Services.
In the event of any failure of the mobile application to comply with any applicable warranty, you may notify the App Provider, and the App Provider may refund the purchase price (if any). To the maximum extent permitted by law, the App Providers will have no other warranty obligation whatsoever.
You agree that the App Providers are third-party beneficiaries of this agreement, and upon your acceptance of the Terms, they will have the right (and be deemed to have accepted the right) to enforce this agreement as third-party beneficiaries.
Governing Law and Jurisdiction will not apply to any disputes for which the parties have actual notice on or before the date the change is posted on the Services.
Your continued use of the Services following the posting of revised Terms of Use means that you accept and agree to the changes. You are expected to check this page from time to time so you are aware of any changes, as they are binding on you.
