Last Updated: June 11, 2025

At 21 Challenge, your privacy is paramount. This Privacy Policy outlines the types of information we collect, how we use it, and the measures we take to protect your data.

1. Information We Do Not Collect

21 Challenge is designed as a skill-based cognitive training game, not a gambling service. We do not require or collect any personal identifying information (PII) from our users such as names, email addresses, physical addresses, phone numbers, or financial details. We also do not track your location or use cookies for individual user tracking or advertising purposes.

2. Anonymous Usage Data (Optional)

We may collect **anonymous, aggregated usage data** to understand how our game is used and to improve the user experience. This data includes:

  • Game session duration
  • Number of games played
  • Feature usage (e.g., how often certain buttons are clicked)
  • Performance data (e.g., game load times)
  • Device type (e.g., mobile, desktop, tablet)

This information is entirely anonymous and cannot be used to identify you personally. It is collected for analytical purposes only and helps us make the game better for everyone.

3. How We Use Anonymous Data

The anonymous usage data we collect is used solely for the following purposes:

  • To analyze game performance and stability.
  • To improve game features and user interface.
  • To understand general user engagement patterns.
  • For internal reporting and development planning.

4. Data Security

Although we collect minimal data, we implement robust security measures to protect the anonymous data we do receive from unauthorized access, alteration, disclosure, or destruction. We use industry-standard practices to ensure the integrity of our systems.

5. Third-Party Services

We do not share any data, anonymous or otherwise, with third-party advertising networks or data brokers. If we were to integrate any third-party analytics services in the future, we would ensure they adhere to strict privacy standards and that any data shared remains anonymous and aggregated.

6. Children's Privacy

21 Challenge is suitable for all ages as it does not involve gambling or personal data collection. We are in compliance with the Children's Online Privacy Protection Act (COPPA) and other relevant regulations, as we do not collect PII from anyone, including children under 13.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. We encourage you to review this Privacy Policy periodically for any changes. Your continued use of the game after any modifications constitutes your acknowledgment of the modified Privacy Policy and agreement to abide and be bound by it.
