Davyn Payroll for Business Central
- Last updated: 24 April, 2026

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.
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.
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.
Section 03

The App processes the following categories of personal and business data, all of which reside within your Business Central tenant:

3.2 Payroll & Financial Data

Your Organisation
Data Controller
Your organisation controls all personal data processed through the App and is fully responsible for it.
Davyn Ltd
Data Processor
Davyn acts as a processor solely through the App software. We do not independently control or access your data.
Section 05
Data Sharing & Sub-Processors
The App interacts with the following Microsoft services as part of Business Central’s standard operation, governed by Microsoft’s own privacy commitments:
- Microsoft Dynamics 365 Business Central (host platform)
- Microsoft Exchange / Microsoft 365 (if email payslip delivery is enabled, using your organisation’s email server configuration)
Davyn does not use third-party analytics, tracking, or telemetry tools within the App.
Section 06
Data Retention
Data created by the App — payroll batches, calculations, logs, and payslips — is retained within your Business Central tenant for as long as your organisation requires, subject to your own data retention policies.
To delete specific payroll records, your Business Central administrator can use the standard Business Central data management tools. Contact Davyn support for assistance with bulk data deletion if required.
Section 07
Data Subject Rights
Because Davyn does not hold or control your payroll data, requests from employees (data subjects) to access, correct, export, or delete their personal data must be directed to your organisation as the data controller.
Section 08
Security
Davyn Payroll for Business Central relies on the security infrastructure of Microsoft Dynamics 365 Business Central, which includes:
- Encryption in Transit:
TLS encryption for all data transmitted within the Business Central platform. - Encryption at Rest:
Managed by Microsoft at the infrastructure level. - Role-Based Access Control:
Only users with appropriate permissions can access payroll data. - Multi-Factor Authentication:
Configured via your Microsoft 365 / Entra ID tenant.
Section 09
Children’s Privacy
The App is designed for use by organisations processing adult employee payroll data. It is not intended for use with personal data of individuals under the age of 16, and we do not knowingly process such data through the App.
Section 10
International Data Transfers
The App does not transfer data to Davyn or any third party. Data residency is determined by your Microsoft Business Central tenant configuration.
If your organisation operates across multiple jurisdictions, your data residency obligations are governed by your agreement with Microsoft.
