Introduction

This Data Processing Agreement ("DPA") forms part of the Terms of Service between Supalytics ("Processor", "we", "us") and the customer ("Controller", "you") using our web analytics service.

Important Note: Because Supalytics does not collect personal data from website visitors, a traditional DPA may not be legally required. However, we provide this document for transparency and to address our handling of your account data.
