1. About This Policy

H2 Business Systems Limited ("H2", "we", "us") is a company registered in England and Wales. This policy explains how we handle personal information in connection with this website and with Essential Rental, our extension for Microsoft Dynamics 365 Business Central.

It should be read alongside our Licence Terms & Conditions, which governs your use of the software itself.

2. Your Business Data

Essential Rental runs inside your own Microsoft Dynamics 365 Business Central environment. The rental, customer, pricing and other business records the software creates and uses stay within your Business Central tenant, under your control. We do not access, copy, or store this data in the ordinary course of providing the software.

3. Telemetry We Collect

The software collects operational telemetry - such as activation events, which modules and features are in use, and diagnostic information when something goes wrong. This is used to monitor performance, diagnose faults and guide product improvements.

This telemetry does not include your business records, customer data, or the content of your rental, invoicing or pricing information.

4. Support Access

If you contact us for support and choose to grant us access to your Business Central environment to help resolve an issue, we will use that access only for the purpose of investigating and resolving the issue you have raised.

5. This Website

This website does not currently use analytics or marketing tracking cookies. Our hosting provider may keep standard technical logs (such as IP address and request details) for security and reliability purposes.

The website includes a chat widget provided by Microsoft (Copilot Studio / Customer Connect). Messages you send through it are processed by Microsoft in accordance with Microsoft's own privacy terms, not this policy. Avoid sending sensitive personal information through the chat widget.

6. Legal Basis & Your Rights

Where we process personal information (for example, contact details for a support request, or the telemetry described above), we rely on our legitimate interests in operating, supporting and improving the software, or on taking steps to perform our contract with you.

Under UK GDPR you have the right to request access to, correction of, or erasure of your personal information, to object to or restrict certain processing, and to request that your information be provided in a portable format. You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.

To exercise any of these rights, contact us using the details below.

7. International Transfers

Your Business Central data is hosted by Microsoft in the region associated with your Business Central environment; H2 does not itself store or relocate that data. Where any personal information we hold directly (such as support correspondence) is processed by a supplier located outside the UK or EEA, we ensure appropriate safeguards are in place, such as the UK International Data Transfer Addendum or equivalent standard contractual clauses.

8. Data Retention

We retain telemetry and support correspondence only for as long as needed for the purposes described in this policy, or as required by law. Your business data in Business Central is retained according to your own organisation's practices and Microsoft's retention terms for your tenant, not by us.

9. Children's Privacy

Essential Rental is business software intended for use by organisations and their staff. It is not directed at, and we do not knowingly collect personal information from, children.

10. Changes to This Policy

We may update this policy from time to time. The version published on this page applies from its "Last updated" date. We will highlight material changes on this page.
