The short version
This website is a set of static files served from a CDN. It has no login, no shopping basket and no server-side session, so it has no reason to set a cookie — and it does not set one. Nothing about you is transmitted to us, or to anybody else, by visiting a page.
A site that genuinely sets no cookies does not need a consent banner under PECR or the ePrivacy Directive. The absence of the banner is the point, not an oversight.
What is stored in your browser
Two values are written to your own browser and never leave it. They are stored in Web Storage rather than in cookies, which means they are not attached to any request and no server — ours or anyone’s — ever receives them.
| Key | Store | Purpose | Lifetime |
|---|---|---|---|
| arcwright-theme | localStorage | Remembers your light/dark choice and colour preset, so the page does not flash the wrong theme on your next visit | Until you clear it |
| arcwright-preloader | sessionStorage | Records that the opening animation has already played, so it does not replay on every page you open | Until the tab is closed |
Neither key contains personal data, an identifier, or anything that could be used to recognise you across sites. Deleting them costs you nothing except the theme preference, which the site will simply ask your operating system for again.
What we deliberately do not do
The following are all absent by design rather than by omission, and each was a decision somebody had to defend:
- No analytics of any kind — including the self-hosted, "privacy-friendly" variety.
- No advertising or retargeting pixels, and no conversion tracking.
- No session recording, heatmaps, or scroll-depth instrumentation.
- No fonts, scripts or stylesheets loaded from a third-party domain; typefaces are self-hosted at build time, so no external service sees your IP address.
- No chat widget, no A/B testing harness, and no "customer data platform".
The cost of that position is that we do not know how many people read any of this. We consider it a reasonable trade for a firm whose clients hand it clinical and financial records.
Embedded third-party content
Two places on this site are designed to hold a third-party embed: the scheduling dialog on the contact page and the media containers on the testimonials page. In this build both are empty slots, so neither loads anything from anywhere.
If a provider is ever configured into one of them, that provider will set its own cookies under its own policy, this notice will name it in the table above, and its version number will change. An embed appearing without this page changing would be a defect.
How to remove what is stored
- Clearing site data for this domain in your browser removes both keys immediately.
- Private or incognito browsing discards them when the window closes.
- Browsing with JavaScript disabled means neither is ever written; the site renders and reads normally, using your operating system’s light or dark preference.
There is no preference centre on this page because there is nothing to switch off. A control that does nothing is worse than no control.
Changes to this notice
The version and effective date in the title block are the record. Because the table above is a complete inventory rather than a summary, any addition to what this site stores requires a change to this page — and we would publish that change before the code shipped, not after.
Found something we have not declared?
If you inspect this site and find storage or a network request that is not described above, we would genuinely like to know. That is a bug in the site or a bug in this page, and both get fixed.
