Cookie policy
We use essential browser storage and offer optional analytics. This page explains what each does, how long it lasts and how to accept, reject or change your analytics choice.

What this site stores today
Essential security storage supports the enquiry form. Optional analytics only starts after your acceptance.
We do not use advertising cookies, advertising pixels or third-party embeds. Google signals and advertising personalisation are disabled in our analytics configuration.
Where Google Analytics 4 is enabled, its script only loads and its cookies are only set after you choose Accept analytics. It uses pseudonymous browser and session identifiers to understand visits, page views and selected interactions. We use these in summarised reports, never for advertising. See how to manage your choice below.
We protect the contact form with Vercel BotID, which checks whether a submission is a genuine person or automated traffic. That check can write to your browser's session storage, not a cookie, and it clears itself when you close the tab.
Analytics events do not include your enquiry's contents. Reported page addresses exclude query strings and fragments. Preview and local development sites do not run analytics by default.
Every item, in one table
The same list, laid out by what it is, who sets it, and how long it lasts.
| Item | Set by | Type | Purpose | Duration |
|---|---|---|---|---|
| Advertising cookie or pixel | None | Not set | We run no advertising cookie and no cross-site tracking pixel | Not applicable |
| Analytics cookie (optional) | Google Analytics 4, only if you accept it | Cookie, for example _ga and _ga_<container id> | Distinguishes browser visits and sessions for site-usage reports using pseudonymous identifiers; only after acceptance, never for advertising | Up to 2 years from the most recent accepted visit; removed from this site if you withdraw consent |
| Cookie choice | MSD Systems (this site) | Browser local storage (msd_consent), not a cookie | Remembers whether you accepted or rejected analytics, so we do not ask on every page | Valid for 183 days (about 6 months), then we ask again. The saved record remains until replaced or cleared; local storage does not expire by itself |
| Refusal safeguard (only if saving a choice fails) | MSD Systems (this site) | First-party cookie and session storage (msd_consent_revoked) | Keeps analytics off when a browser cannot save the normal consent record | Cookie: up to 183 days; session storage: until the tab closes. Removed when a new acceptance is successfully saved |
| Automated-traffic check | Vercel BotID | Session storage, not a cookie | Checks contact-form requests for signs of automated traffic | Cleared when the browser tab closes |
| Third-party embeds | None | Not applicable | Not used on this site | Not applicable |
How to control cookies and storage
Your browser provides controls for cookies and site storage. If a security check prevents a form submission, you can email us directly.
Block cookies in your browser
Every modern browser has a setting to block or limit cookies, by site or entirely. You can continue to read the website with cookies blocked. If browser restrictions prevent a form submission, you can email us directly.
Clear session storage
The session storage used by the contact-form check clears itself automatically when you close the browser tab. You can also clear it manually from your browser's site-data or developer-tools settings.
Change your analytics choice at any time
Where analytics is enabled, use Cookie settings in the footer to reopen the choice. Reject analytics stops further collection and removes this site's analytics cookies. It does not delete information Google has already received. You can also clear the saved choice through your browser's site-data settings.
