last_updated: 2025-12-13



Privacy Policy

Contest Reminder – Coding Competition Alerts ("the extension") is designed to help users track upcoming competitive programming contests and receive reminder notifications. We value your privacy and are committed to protecting it.



1. Information We Collect

1.1. Personal Information

With the introduction of Premium features and Calendar integration in version 2.5, the extension now interacts with your Google account in the following limited ways:

• Email Address: We access your email address via Google Sign-In solely to verify your identity and determine your subscription tier (Free, Pro, or Premium).
• Calendar Data: We access your Google Calendar to add, update, or remove contest reminders that you explicitly choose to sync.

We do not sell, trade, or share your email address or calendar data with third parties.

1.2. Local Data

The extension stores the following preferences only on your device:

• Selected platforms (e.g., Codeforces, LeetCode, CodeChef, etc.)
• Notification preferences
• Theme settings (dark/light mode)
• Sync settings (e.g., last sync time)

2. Permissions and Usage

The extension requests the following permissions to support its functionality:

| Permission | Purpose |
|-----------|---------|
| notifications | To send reminders shortly before contests begin. |
| alarms | To schedule contest reminders and background sync tasks. |
| storage | To save user preferences locally. |
| identity | To authenticate you with Google for Calendar integration and Premium features. |

2.1. Google API Scopes

We request specific scopes to interact with Google services:

• https://www.googleapis.com/auth/calendar.events: To create and manage contest events on your calendar.
• https://www.googleapis.com/auth/userinfo.email: To identify your account for subscription management.

3. Remote Data Retrieval

• Contest Data: The extension retrieves publicly available contest schedule data from competitive programming platforms.
• Google APIs: The extension communicates directly with Google's servers to sync your calendar and verify your account.

No remote executable code is ever loaded or run.



4. Data Sharing and Third Parties

We do not:

• Sell user data.
• Use third-party analytics.
• Track user behavior across the web.

Data is only shared with Google as strictly necessary to fulfill the Calendar sync and Authentication features you request.



5. Data Protection

We are committed to ensuring the security of your sensitive data.

• Encryption: All data transmission between the extension and Google APIs occurs over secure HTTPS (TLS/SSL) protocols.
• Secure Storage: Authentication tokens are managed securely via the Chrome Identity API. We do not store your Google account credentials or personal data on external servers.

6. Data Retention and Deletion

We adhere to the following policies regarding the retention and deletion of your data:

• Retention: Your email address and authentication status are retained only while you are signed in to the extension. Local preferences (such as platform selection and theme) are stored on your device as long as the extension is installed.
• Deletion: You can revoke the extension's access to your Google account at any time via your Google Account Security Settings. Uninstalling the extension will permanently delete all locally stored data and preferences. Calendar events created by the extension can be deleted directly through your Google Calendar.

7. Children’s Privacy

This extension is safe for all users and does not knowingly collect data from children under 13 or any other age group.

We may update this Privacy Policy if features change. Any updates will be reflected on this page with a revised "Last Updated" date.
