UA Info — User Agent parsing

What is UA Info?

The UA Info add-on automatically parses the User Agent string and adds structured headers (X-DataNostro-Browser, X-DataNostro-OS, X-DataNostro-Device) to all requests.

Why use UA Info?

• Segmentation: Analyze conversions by browser/device.
• QA: Quickly identify browser-specific problems.
• Personalization: Adapt tracking based on device type.
• Reporting: Cross-device analysis without complex parsing.
