Terms of Use

The agreement that governs our Services

Last updated: May 12, 2026

These Terms of Use (“Terms”) govern your access to and use of neurantra.com and Puzzlecub(together, the “Services”), provided by Neurantra LLC (“Neurantra,” “we,” “us,” “our”). By using the Services, you agree to these Terms. If you do not agree, do not use the Services.

Our other products IyerSpine and Pawcial are governed by separate terms, available on their respective websites.

1. Eligibility

The neurantra.com website is intended for users 13 years of age or older. By using the website, you represent that you meet this minimum age requirement, or that a parent or legal guardian has reviewed the site on your behalf.

Puzzlecub is designed for players of every age. On first launch, Puzzlecub asks each player for their year of birth and applies additional safety protections — non-personalized advertising and parental gates on outbound links — to any user whose locally-entered age indicates they are under 13 (or under 16 in the European Union). When a child uses Puzzlecub, the parent or legal guardian agrees to these Terms on the child’s behalf and is responsible for the child’s use of the app.
