What data we collect and why

Enquiry form

When you submit an enquiry, we collect your name, email address, and the content of your message. We use this solely to respond to your enquiry. We do not add you to any mailing list, pass your details to third parties, or use them for any other purpose without asking you first.

Legal basis: Legitimate interests (responding to a direct enquiry you initiated).

Newsletter signup

If you choose to subscribe to updates, we collect your email address for that purpose only. You can unsubscribe at any time using the link in any email we send, or by contacting us directly.

Legal basis: Consent.

The platform used to manage newsletter subscriptions will be named here once confirmed. Any third-party processor used for this purpose will be operating under a data processing agreement and appropriate safeguards.

Analytics (GA4 via Cloudflare Web Tag)

We use Google Analytics 4, loaded through Cloudflare’s server-side web tag. This collects anonymised data about how visitors use the site: pages visited, time on site, approximate location (country or region level), device type, and referral source. No personally identifiable information is captured through analytics.

IP addresses are anonymised before processing. Data is processed by Google in accordance with their data processing terms.

Legal basis: Legitimate interests (understanding how the site is used in order to improve it). You can opt out of analytics tracking via your browser settings or a tool such as the Google Analytics Opt-out Browser Add-on.

Commonly Asked Questions

Do You Really Guarantee Outcomes?
On eligible projects, yes. A specific commitment with a defined consequence if we miss it. That is not a marketing line, it is what confidence looks like when it is willing to be measured. Not every project qualifies, and we will tell you honestly whether yours does.
For e-commerce and lead generation projects with clear commercial upside, we work at near cost in exchange for a share of the additional revenue we generate. We take a stake in the result because we are confident enough to bet on our own work. It is not offered to everyone. It needs a viable business, a real opportunity, and a straight conversation first.
Based in Warwick, working on site across Warwickshire, Shropshire and the wider Midlands, and remotely across the UK and internationally.

Plenty of security work has to happen in the building: configuring firewalls, securing the network, setting up machines, training the people who actually click the links. We travel for that. Remote where it makes sense, in person where it matters.
Yes, on retainer. Certification lapses, threats move, and staff turn over. Ongoing support keeps the controls in place between annual renewals, handles incidents when they come, and means the person who built your security is the person who maintains it. No ticket queue. No stranger relearning your estate every time.
Both. Alongside client work we build and sell our own tools, like custom systems for e-commerce, with more in development. The same standards apply: built properly, supported directly, and made to do one job well rather than ten jobs badly.
