What we collect

LeetRevise collects your Google account name and email address for authentication purposes only. If you connect Google Calendar, we store an OAuth refresh token to create calendar events on your behalf.

How we use it

Your data is used solely to schedule LeetCode revision reminders on days 3, 7, 15, and 30 after you mark a problem. We never sell, share, or use your data for advertising.

Google Calendar access

We request the calendar.events scope only to create revision reminder events titled "Revise: [problem name]".We only access your Google Calendar to schedule revision events; we do not store, share, or sell your personal calendar data.

Data retention & deletion

You can disconnect Google Calendar at any time from your dashboard settings. To permanently delete your account and all associated data, email us at karthicksaai197@gmail.com and we will process it within 7 days.

Third-party services

We use Supabase for database and authentication, Google OAuth for sign-in, and Resend for email delivery. Each service has its own privacy policy.

Data Protection & Retention

• Encryption in Transit: All data transferred between the extension and our servers is protected using industry-standard TLS/SSL encryption.
• Encryption at Rest: Sensitive information, such as OAuth tokens, is stored in our Supabase database using AES-256 encryption.
• Secure Authentication: We use Google OAuth 2.0 for all sign-ins, meaning we never see or store your Google account password.
• Account Deletion: You can disconnect Google Calendar via your dashboard. To permanently delete your account and all data, email karthicksaai197@gmail.com; requests are processed within 7 days.

Data Sharing and Disclosure

We do not sell or trade your personal information. We share data with third-party service providers (Supabase for database hosting, Resend for email notifications) only to the extent necessary to provide the LeetRevise service. We may disclose your information if required by law or to protect our rights. We do not share your Google user data with any other third parties for their own marketing purposes.
