Privacy Policy

1. Information We Collect

When you sign in to Leetly using Google or another identity provider through Keycloak, we receive and store the following information:

• Your name and email address
• Profile picture (if provided by the identity provider)
• Authentication tokens (used to keep you signed in securely)

We also store data you create within the app, including problem attempts, notes, custom lists, and analytics derived from your activity.

2. How We Use Your Information

Your information is used exclusively to:

• Authenticate you and maintain your session

• Generate personal analytics and progress reports

We do not use your data for advertising, profiling, or any purpose beyond providing the Leetly service.

3. Data Sharing

4. Data Storage & Security

Your data is stored securely in our database hosted on infrastructure we operate. We use HTTPS for all data in transit and employ industry-standard security practices, including encrypted tokens and secure session management through Keycloak.

5. Data Retention & Deletion

We retain your data for as long as your account is active. You may request deletion of your account and all associated data at any time by contacting us. Upon request, your data will be permanently deleted within 30 days.

6. Third-Party Services

Leetly integrates with the following third-party services:

• Google OAuth — for sign-in authentication
• Keycloak — as our identity and access management provider

These services have their own privacy policies. We encourage you to review them.

8. Your Rights

You have the right to:

• Access the personal data we hold about you
