2. Membership Access

Lifetime Access: A one-time purchase grants you lifetime access to the Addition Mastery course modules, including all associated interactive games and worksheets.

Personal Use Only: Your account is for individual use. Systematic sharing of login links or distributing content to third parties is prohibited and may result in immediate suspension.

3. Refund Policy

Abuse Protection: Refunds will not be granted if we detect that the entire 30-day curriculum or all worksheet PDFs were downloaded within 48 hours of purchase.

4. Results Disclaimer

Math Mastery provides cognitive training tools. While based on spaced repetition science, we do not guarantee specific academic results, standardized test scores, or professional performance outcomes.

5. Termination of Access

We reserve the right to revoke access for any user attempting to reverse-engineer our interactive games, exploit security vulnerabilities, or bypass the payment system.
