Privacy Policy

1. Information We Collect

1.1 Data Processed Locally

When you use Chatlyzer, the app processes your WhatsApp chat exports locally on your device. This includes:

• Message text content
• Timestamps and metadata
• Participant information (names/contacts)
• Media file references (not the actual media files)

Important: This data is processed entirely on your device and is never transmitted to our servers.

1.2 Analytics Data

To improve our app, we may collect anonymized usage analytics:

• App usage patterns (which features are used most)
• Performance metrics (app crashes, loading times)
• Device information (OS version, device model)
• General app interactions (buttons clicked, screens viewed)

This data is completely anonymized and cannot be traced back to specific users or their messages.
