Privacy Policy

Effective Date: January 22, 2026

NTU Course2Cal ("we", "our", or "us") respects your privacy. We are committed to protecting the personal information you share with us. This policy describes how we handle your data when you use our application to sync your course schedule with Google Calendar.

1. Data Collection and Usage

We do not sell your personal data. The application accesses the following data types exclusively to provide the scheduling service:

• Google User Profile (Name, Email, Profile Picture): Used solely to identify the active user session and to display your identity within the app.
• Google Calendar Data:
  • We read your existing calendars to identify the primary calendar and prevent scheduling conflicts.
  • We write (add/edit) events to your calendar to populate it with your NTU course schedule.

2. Data Protection Mechanisms

We employ industry-standard security measures to protect your information:

• Encryption in Transit: All data transmitted between the application, your device, and Google's servers is encrypted using HTTPS/TLS (Transport Layer Security) protocols.
• Secure Storage: OAuth 2.0 access tokens and refresh tokens are stored securely on your local device using the operating system's secure keychain or encrypted storage mechanisms. We do not store your calendar data on external servers; it is processed directly on your device or in temporary memory during the sync process.

3. Data Retention and Deletion Policy

We retain your data only for as long as necessary to provide the service:

• Retention: User profile data is retained only while you are logged into the application. Calendar data is fetched on-demand and is not permanently archived on our systems.
• Deletion: You may revoke the application's access at any time via your Google Account Security Settings. Upon revocation, the application will lose access to your data. To request the deletion of any locally stored preferences or data, please uninstall the application or contact us at the email below.

4. Limited Use Disclosure

The NTU Course2Cal App's use and transfer to any other app of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.
