Section 01

Introduction

This Privacy Policy describes how Davyn Ltd (“Davyn”, “we”, “us”, or “our”) handles data in connection with Davyn Payroll for Business Central (the “App”) — a software extension for Microsoft Dynamics 365 Business Central distributed through Microsoft AppSource.

This policy is specific to the Davyn Payroll for Business Central application. It supplements our general website privacy policy and governs the collection, processing, storage, and handling of data within the App.

By installing or using the App, the organisation administering the installation (the “Customer”) acknowledges this Privacy Policy on behalf of themselves and the individuals whose data is processed through the App.

Section 02

How the App Works & Where Data Lives

Davyn Payroll for Business Central is a native Business Central extension installed directly within your organisation’s Microsoft Dynamics 365 Business Central environment.

All data processed by the App is stored exclusively within your organisation’s Business Central tenant. The App does not transmit data to Davyn’s servers, third-party servers, or any external systems during normal operation.

This means:

  • Data Residency follows your Business Central tenant’s region, as configured by your organisation with Microsoft.
  • Data Ownership remains entirely with the Customer (your organisation).
  • Tenant Isolation is maintained – the App cannot access data from any other Business Central tenant.
  • Zero Davyn Access. Davyn does not have access to your payroll data, employee records, or financial data.
