1. Information We Access

CodeSmash Arena may access the following information:

• Codeforces Username: The extension uses Codeforces usernames and publicly available Codeforces API data to display profile information, problem-solving history, and submission details.
• Problem Information: The extension reads problem statements, examples, and related information from Codeforces pages to display them in its coding interface.
• Source Code and Test Cases: The extension processes code written by users, along with test case inputs and expected outputs, to provide code execution functionality.
• Editor Preferences: Programming language selections, editor settings, and code drafts may be saved locally in the user's browser.

CodeSmash Arena does not require users to provide their Codeforces passwords.

2. How We Use Information

Information accessed by the extension is used to:

• Display Codeforces problems in an integrated coding environment.
• Save code drafts and user preferences.
• Execute user-written code against test cases.
• Display Codeforces profile information and submission history.
• Submit solutions to Codeforces when requested by the user.

3. Third-Party Services

4. Local Data Storage

CodeSmash Arena uses browser storage to save code drafts, selected programming languages, editor preferences, and extension settings.

This information is stored locally in the user's browser unless a particular feature explicitly requires transmission to an external service.

Users can remove locally stored extension data through Chrome's extension and site-data controls. Uninstalling the extension may remove extension-specific storage, but data stored by the Codeforces website may require separate deletion.

5. Data Sharing

• CodeSmash Arena does not sell users' personal information.
• Information is transmitted to Codeforces and Judge0 only as necessary to provide the extension's requested functionality.
• We do not use extension data for advertising, creditworthiness assessments, or unrelated purposes.

6. Data Retention

Code drafts and preferences may remain in browser storage until users clear the relevant data or uninstall the extension.

Codeforces and Judge0 may retain information submitted to their services according to their own policies.

7. Security

We aim to protect user information through appropriate security practices, including HTTPS connections to external services.

No internet-based service can guarantee absolute security.

8. Children's Privacy

CodeSmash Arena is intended as a programming and educational tool. We do not knowingly collect personal information from children in violation of applicable laws.

9. Changes to This Policy

We may update this privacy policy to reflect changes in the extension's functionality, data handling, or applicable requirements. Updates will be published on this page with a revised last-updated date.
