Effective 29 October 2026

mksvrcek.com is the site of Michael Kimberly Svrcek ("we"), who makes PocaPal, Peregrino, UoP Bus and Keepsake. Besides its pages, it runs two kinds of link for the apps and their sites, short links and campaign links, and the tests and personalisation on those sites. This is what they keep.

Short links

An address like mksvrcek.com/s/launch passes you straight on to where it goes. As it does, we note the click:

• when it was, and your country, worked out from your network address, which isn't kept;
• the kind of device, its system, and the browser or app the link was opened in (Safari, Chrome, Instagram…);
• the site the link was on, if your browser says: its name only, never the page;
• a code made from your network address and browser with a key that's deleted after two days, so a day's visitors can be counted once each. Once the key has gone, the code can't be traced back to anyone.

Link previews and other automated requests are kept apart and never counted as people.

Campaign links

Our sites (pocapal.mksvrcek.com, peregrino.mksvrcek.com, uopbus.mksvrcek.com, keepsake.mksvrcek.com and this one) load a small script from mksvrcek.com. It does nothing at all unless you arrive through one of our campaign links, an address tagged with something like ?src=instagram. Then it tells mksvrcek.com which link it was and the page you landed on, with the same details as a short link's click above, and, for the rest of that visit in that browser tab, which of the site's pages you open next and whether you tap through to the App Store.

It remembers the link in the tab's own storage (sessionStorage), which your browser clears when the tab is closed. It sets no cookies. If your browser asks sites not to track it (Do Not Track or Global Privacy Control), it sends nothing.

Tests and personalisation

Our sites also load a second small script from mksvrcek.com, which lets us try changes to a page (two versions of a button, say, to see which helps more people find what they came for) and show a page a little differently depending on how you arrived (from an Instagram link, for example). When nothing is being tried on the site you're on, it does nothing. When something is:

• when two or more versions are being compared, it picks one for you at random and remembers which in a cookie, mk_t, on mksvrcek.com and our sites under it, so you see the same one when you come back. The cookie holds a random number, when it was first set, and which version of each comparison you're seeing, and lasts a year from your last visit to a site where one is running;
• when a page is adapted to how you arrived, it decides from that page alone (its address, the site you came from, its language, your kind of device) and keeps nothing: no cookie, and nothing in your browser's storage;
• it tells mksvrcek.com which version you were shown and whether you then did what the change is about (such as tapping through to the App Store), with the details described for short links above. For a comparison we keep these under a code made from the cookie's number and the comparison, so what you saw in one can't be connected with another; for an adapted page, under a code made the same way as a short link's, from a key deleted after two days.

The cookie is set only when you're in a comparison, and only so the site shows you the same version while it runs: it isn't used for advertising, isn't shared, and nothing else reads it. If your browser asks sites not to track it (Do Not Track or Global Privacy Control), you're never put in a comparison, no cookie is set and nothing is sent, though a page may still be adapted to the link you arrived from. You can delete the cookie whenever you like in your browser's settings, and you'll simply be treated as a new visitor.

What isn't kept

No name, account, email address or network address. Nothing is sold or shared with anyone: the counts tell us only which links people find useful.

Where it's kept, and for how long

Cloudflare hosts this site and processes standard request data (such as IP addresses) to deliver and protect it. The counts are stored in a Cloudflare D1 database that only we can read, through a dashboard behind a sign-in, and are deleted with the link, campaign or test they belong to.

This website

Cloudflare Web Analytics counts visits to its pages without cookies and without identifying or following visitors. Apart from the cookie above, while something is being tried on it, its pages set no cookies. When you choose a language, or close the note offering yours, your browser keeps that choice for this site in its own storage; it is never sent anywhere.
