Privacy Policy

At Kavalu (operated by Urban Folklore Ltd), your privacy is our top priority. We believe in complete transparency about how we handle your data. This privacy policy explains our commitment to protecting your information while providing you with powerful AI-powered learning assistance.

How We Use AI to Help You Learn

When you select text on a webpage and request an explanation, here's exactly what happens:

1. Your selected text is sent securely to our AI processing partners
2. AI generates an explanation tailored to your learning preferences
3. The explanation is sent back to you through our Chrome extension
4. We don't store your selected text - it's processed temporarily and deleted
5. Flashcards are saved locally - stored only on your device, not our servers

This means your browsing content stays private while you get personalized AI assistance.

Why Our Chrome Extension Needs Permissions

Our extension requests these permissions to provide you with seamless learning assistance:

• Access to webpage content: To detect when you select text for explanations
• Storage permission: To save your flashcards and preferences locally
• Network access: To communicate securely with our AI services
• Host permissions: Only for sites where you actively use the extension

We never access your personal information, passwords, or browse your tabs without your explicit action.
