Who runs this

cadvisionstory.com is a historical archive of CADVision Internet (Calgary, 1990–2001), assembled and operated by Jeffrey Shmigelsky in Vancouver, British Columbia. I decide what happens to the information described below. You can reach me at jeffrey@activeq.io.

What this site does not do

There is no contact form, no sign-up, no newsletter, no account and no shop. The site never asks for your name, your email address or anything else about you, and there is nothing here to fill in. If you want to get in touch, you have to send an email — and then I have whatever you chose to put in it, and nothing more.

What is collected

Three analytics services run on every page, and the Google Analytics property is linked to a Google Ads account. I never see who you are: what reaches me is counts and visits, not names. Google is the exception worth knowing about — if you are signed in to a Google account, it may recognise the visit as yours. That is set out under “Google Ads and advertising features” below.

• Google Analytics 4 — which pages were opened, how you arrived (the referring site, a search, or an ad), approximate location worked out from your IP address, and your device and browser type. Google’s enhanced measurement adds scroll depth, clicks on links leaving the site, file downloads and video plays. Two events are counted here that Google does not supply on its own: that a newspaper scan was opened, and that it was magnified past the fitted view. On an archive of clippings, whether anyone actually read one is the only question worth asking.
• PostHog (US Cloud) — clicks, scroll and click maps, page views, and session replay: recordings that reconstruct how a visit moved through the pages. There is nothing on this site to type into, and PostHog masks anything typed into a form field before it leaves the browser in any case. PostHog is configured not to create a profile for an anonymous visitor, and since nobody signs in here, no profile is ever created.
• Vercel Analytics and Speed Insights — page views and how quickly pages loaded, so the site can be kept fast.

Google Ads and advertising features

This site’s Google Analytics property is linked to a Google Ads account, with ads personalisation switched on. If you arrive from a Google ad, the link carries Google’s click identifier (gclid) in the address. Google reads it to attribute the visit to the ad that produced it, and Google Analytics stores it alongside the visit. The link also lets Google Ads use what Google Analytics records here — through Google’s advertising cookies and identifiers — to measure whether advertising for the archive works, and to show ads for the archive to people who have visited it. There is no separate ad conversion tag and no lead form on this site.

The property uses Google Analytics Advertising Features, including Google signals: where you are signed in to a Google account and have allowed ads personalisation, Google may associate your visit with your Google account information, to give me aggregated demographics and interests and cross-device reporting, and for ads personalisation. I do not receive anything from this that identifies you.

Why

To find out which chapters are read, which scans people stop on, and whether the archive is reaching anyone — including whether an ad or a search result brought them — and to keep the pages loading quickly. That is the whole of it. Nothing here is sold or rented, and no one is added to any list. The only parties that receive anything are the services named on this page, and Google uses what it receives in the ways described above.

Cookies, and how to opt out

Google Analytics and PostHog set cookies to tell one visit from the next, and Google’s may be used for advertising as described above. None of them is needed for the site to work: block them in your browser, or use its tracking protection, and every page will still work exactly as it does now. Nothing on this site is behind a cookie banner, because nothing here depends on your accepting one.

You can opt out of Google’s ads personalisation at adssettings.google.com, install the Google Analytics opt-out add-on so that Google Analytics does not record your visits to any site, and review or delete the activity Google has associated with your account at myactivity.google.com.

This site does not respond to a browser’s Do Not Track signal — Google Analytics ignores it, and nothing here is set up to act on it — so the routes above, or blocking cookies, are the ones that work.

Where it goes, and for how long

The site is hosted by Vercel, and Google (Analytics and Ads), PostHog and Vercel all process this data on servers in the United States, so information about your visit is stored outside Canada. Each keeps it on its own schedule: Google Analytics retains event data for at most fourteen months, and PostHog keeps events and session recordings under its own retention settings. Nothing about a visit is copied anywhere else.

Your choices

Because the archive never asks who you are, there is normally no record here that could be tied to you that I could hand over or delete. If you think there is — you emailed me, say, or you believe a session recording captured something of yours — write to jeffrey@activeq.io and I will find it and delete it. No form, no charge.

The archive is run from British Columbia, under Canada’s Personal Information Protection and Electronic Documents Act and British Columbia’s Personal Information Protection Act. If you think I have handled your information badly, tell me first — and you can complain to the Office of the Privacy Commissioner of Canada.

The archive itself

The scans, photographs and documents reproduced here are historical records of a company that closed in 2001. If you appear in one and would rather not, write and say so.

Children

This is a business history. It is not aimed at children and no information is sought from them.

Changes

If what the site does changes, this page changes with it and so does the date at the top.
