Privacy Policy

Effective date: June 29, 2026

Local Practice Data

Grind Roadmap stores selected problem set, theme, and solved progress in your browser local storage. The editor starts fresh each time a problem opens, and those local values stay on your device unless you clear browser data.

Runner And Admin Access

When you run Kotlin code, the source and stdin are sent to the Trei CodeServer runner to compile and execute sample tests. Admin keys used for runner access are kept in browser session storage and are not shown in page content.

Analytics, Feedback, And Support

The site uses Trei web analytics for page and product usage. Feedback sent through trei.dev/feedback is handled by the shared Trei feedback backend with app/source context. For support or deletion questions, email contact.gangwar@gmail.com.
