Privacy Policy

Last updated: 20 August 2026. This policy explains how Corvan Mobile, operating as Thornfield SIM ("we", "us", "our"), collects and uses personal data.

1. Who we are

Thornfield SIM (thornfieldsim.online) is operated by Corvan Mobile. This site provides an independent mobile SIM deals comparison and advisory service, delivered primarily by phone. For contact details, see our Contact page.

2. What data we collect

This website does not use sign-up forms, checkout pages or account creation, so we don't collect personal data through the site itself beyond standard technical data described in Section 4. When you call our advice line, we may collect:

  • Your phone number (via caller line identification) and any details you choose to share, such as your name, postcode area, and mobile usage habits;
  • A recording or transcript of the call, where recording is enabled;
  • Details of the plan or provider you express interest in, if you ask us to help you switch.

3. Why we collect it

We use this information to: give you relevant, accurate comparison advice during the call; process a switch or referral if you ask us to; maintain call quality and staff training; and meet our own record-keeping and complaint-handling obligations.

4. Website technical data

Like most websites, our hosting and analytics tools may automatically log basic technical data such as IP address, browser type, device type, and pages visited, for security and performance purposes. See our Cookie Policy for details on cookies and similar technologies.

5. Legal basis for processing

We rely on the following legal bases under UK GDPR: legitimate interests (to operate and improve our advisory service), consent (for call recording, where applicable, and non-essential cookies), and contract (where processing is necessary to act on your request to compare or switch a plan).

6. Who we share data with

We may share relevant details with a mobile network or SIM provider only where you've asked us to help you switch to them. We do not sell personal data to third parties. We may share data with service providers who support our call handling and hosting infrastructure, under appropriate data processing terms.

7. How long we keep data

Call recordings and related records are typically retained for a limited period sufficient for training, quality assurance and dispute resolution, after which they are deleted or anonymised, unless a longer period is required by law or an ongoing complaint.

8. Your rights

Under UK GDPR you have the right to request access to, correction of, or deletion of your personal data, to object to or restrict certain processing, and to data portability where applicable. To exercise any of these rights, contact us using the details on our Contact page.

9. Complaints

If you're unhappy with how we've handled your data, please contact us first via our Complaints Procedure. You also have the right to lodge a complaint with the UK Information Commissioner's Office (ICO) at ico.org.uk.

10. Changes to this policy

We may update this policy from time to time to reflect changes in our practices or legal requirements. The "last updated" date at the top of this page will always reflect the latest version.
