Who controls your data

There are two parties involved in running this service, and which one is the data controller depends on the type of data:

Anvul Ltd is the data controller only for platform- and account-level data — for example, the login credentials and sign-in tokens used to operate the platform, security and fraud-prevention logs, and aggregated, de-identified analytics it uses to improve the product.

In short: {{ trading_name|default:"FreeMCS" }} decides what happens with your survey and install data; Anvul Ltd provides the platform that makes it work.

What data we collect

Why we use it

Lawful basis

Your survey and install data is processed under UK GDPR on these bases, decided by your installer ({{ trading_name|default:"FreeMCS" }}) as controller:

Anvul Ltd relies on its own legitimate interest as controller of the platform- and account-level data described above — running, securing and improving the service — and processes all your survey and install data only on your installer's instructions.

Who we share data with

We share the minimum data needed to do the job:

We do not sell your data.

Data retention

We keep your survey, design and install records for seven (7) years. This matches the warranty period on most heat-pump installs and the document-retention requirement for HMRC and grant audits. After 7 years, records are deleted or anonymised.

International transfers

Your data is stored on UK and EU servers. If we ever move it outside the UK / EEA we will use the UK International Data Transfer Agreement (IDTA) or the EU Standard Contractual Clauses, with additional safeguards as required.

Your rights

Under UK GDPR (Articles 15–22) you have the right to:

Cookies

We use a small number of cookies and similar technologies. The full list and your controls are on the cookies page.

Who to contact

Because {{ trading_name|default:"FreeMCS" }} is the data controller for your survey and install data, requests about that data — access, correction, deletion and the other rights above — are handled by your installer; you can reach them via the contact page. For platform- or account-level matters, or any data processing handled by Anvul Ltd, you can reach Anvul Ltd's Data Protection Officer at dpo@freemcs.com.

If your complaint cannot be resolved, you have the right to lodge one with the Information Commissioner's Office (ico.org.uk) — you do not need to use our process first.

Changes to this policy

If we make a material change we will publish a new effective date and, where required, ask for fresh consent on cookies or marketing.
