Privacy policy

This site collects very little, and this page says exactly what.

Last updated 6 September 2026

In short

No cookies

This site sets no cookie of any kind.
No third-party tracking

No analytics service, no advertising, no embedded widgets. The only outside request is for the web fonts.
Anonymous usage statistics

A random identifier that lives in your tab and disappears when you close it. Your IP address is never stored — only your country.
Opt out with one switch

Turn on Do Not Track or Global Privacy Control and the site records nothing at all.
Your enquiry stays with us

The contact form writes to our own database. It is used to reply to you, and never sold, shared or added to a list.

What we collect, and why

Website usage

We record which pages are viewed, how far they are read, and whether the interactive demo is used, so that we can see what works on the site. This is anonymous: the identifier is random, lives only in your browser tab, and is gone when you close it. We cannot recognise you when you come back, and we cannot join two visits together.

We never store your IP address, your browser’s user-agent string, or anything you type. Your IP address is used once, at the edge, to derive a two-letter country code, and then discarded.

Our basis for this is our legitimate interest in understanding how the site is used. If you would rather not be counted, turn on Do Not Track or Global Privacy Control in your browser and nothing is recorded.

Your enquiry

The contact form asks for your name, your email address and your message. A phone number and a hospital or organisation are optional. A checkbox lets you mark the message as a request for pilot access.

We use what you send to reply to you and, for a pilot request, to judge whether a pilot at your site is realistic. It is written to our own database, not to a form service, and it is not sold, shared or added to a marketing list. Nothing is emailed onward automatically: a person reads it. Mail to info@apec-international.com is delivered through Google Workspace, our mail provider.

Our basis for this is our legitimate interest in responding to you. We keep enquiries while we are dealing with them, and delete yours on request.

Your rights

Under UK GDPR you can exercise any of the following by writing to info@apec-international.com. We respond within the statutory deadline.

Access: Ask what personal data we hold about you and get a copy.
Correction: Ask us to correct anything that is wrong or incomplete.
Deletion: Ask us to delete what we hold about you.
Objection: Object to our processing. For website statistics the opt-out is immediate: turn on Do Not Track or Global Privacy Control.

One limitation: we cannot find you in the website statistics, because nothing in them identifies you. A request about that data can only be answered with this page. Your enquiry email is different — that we can find, and delete. You can also complain to the Information Commissioner’s Office at ico.org.uk.

The technical detail Every storage key, every event type, every limit — from the code that runs.

Browser storage

Keys this site can write to browser storage

apec-theme	localStorage	The word light or dark.	Only if you use the light/dark toggle.
apec.vid	localStorage	A persistent visitor identifier.	Never. The code that could write it is not called anywhere on this site.

Every stored row also carries

Time: Server clock when the batch arrives.
Path: The page path, no query string.
Session id: The random value from sessionStorage.
Country: Two letters, resolved by Cloudflare at the edge. The IP address itself is never written.
Device: Phone, tablet or desktop, from viewport width.
Viewport: Width and height in CSS pixels.
Time zone: The IANA name your browser reports.
Referrer: The origin you arrived from, never the full URL.

Limits at the edge

Batch: At most 50 events per request.
Body: Requests over 32 KB are rejected.
Rate: More than 400 events from one session in an hour are discarded.
Type: Any event type not on the list is dropped.

Where it goes

Events are batched in your tab and sent to /api/events on this domain, a Cloudflare Pages Function that writes one row per event into a Cloudflare D1 database. If the request fails, the events are dropped and nothing is retried.

Append ?debug=events to any URL on this site to watch every event it captures, live.
