Privacy Policy

Last updated: July 29, 2026

1. Information We Collect

We collect information you provide directly to us when you create an account, update your profile, submit practice essays or prompts, participate in online matches, or communicate with us. This includes your name, username, email address, profile picture, country flag preference, and text submissions. We also automatically collect technical data such as IP address, browser type, device info, language preferences, and usage analytics.

2. How We Use Your Information

We use your information to operate, maintain, and improve ClashClass, evaluate your writing submissions using AI models, calculate Elo skill ratings, update global leaderboards, perform content moderation, manage subscriptions, deliver customer support, personalize your learning experience, and train, fine-tune, and improve our proprietary machine learning and artificial intelligence models using de-identified or aggregated submission data.

3. Third-Party Data Sharing & AI Model Training

To provide real-time writing feedback, content safety moderation, secure authentication, and payment processing, your data may be processed by trusted third-party service providers. User credentials and profile details are securely managed by authentication providers, while payment details are processed directly by payment gateways. Submitted practice text, essays, and prompts may be transmitted to secure third-party AI processing services and used to train, evaluate, and fine-tune AI models. We do not sell your personal data.

4. Advertising and Analytics

We may partner with third-party advertising networks and analytics providers to serve advertisements and measure service traffic. Third-party vendors use cookies, web beacons, or unique device identifiers to display relevant ads based on your visits to our platform and other websites. You can manage your ad personalization preferences through your browser settings or third-party opt-out mechanisms.

5. Cookies & Tracking Technologies

We use essential functional cookies to save your language, theme, and session preferences across visits. Third-party partners may also set performance and advertising cookies to analyze traffic and measure ad effectiveness.

6. Security, Fraud Prevention & Data Retention

We employ industry-standard encryption and security measures to protect your information. To prevent fraud, maintain system integrity, and enforce actions against malicious or abusive users, technical access logs and security records may be retained as necessary even after account closure or deletion requests, as permitted by law.

7. Children's Privacy & Cross-Border Transfers

ClashClass is intended for users who are at least 13 years of age (or the minimum legal age required in your jurisdiction). We do not knowingly collect personal information from children under 13 without appropriate consent. Your information may be transferred to, stored, and processed in cloud servers located outside your home country by our infrastructure providers.

8. Privacy Policy Updates & Contact

We may update this Privacy Policy periodically to reflect service modifications or legal requirements. Material updates will be posted on this page with an updated revised date. If you have questions regarding this policy, please contact our support team.
