Privacy Policy

Last updated: 15 October 2026.

This page describes what happens when you visit klasen-development.com or write to Klasen Development LLC. It is a plain description of how the site works, not a legal certification.

The short version

  • Access logs. Like most websites, the network that delivers this site keeps standard access logs of every request, including your IP address. They are kept for 30 days and then deleted, and they apply to every visit: you cannot opt out of them.
  • Links in our emails may carry a short code that tells us the link was opened.
  • Optional analytics run only if you choose Accept analytics. You can change your mind at any time with the Privacy choices link at the foot of every page.

Access logs

The site is delivered by Amazon Web Services. For every request, its network records standard details such as the time, the page requested, the referring page, your browser type and your IP address.

We use these logs to understand traffic to the site, to see whether links we send by email were opened, and to tell real visitors from automated programs. IP addresses are used only for that last purpose and are never shown on any page or summary. The logs are kept privately and deleted after 30 days; what we keep longer are totals with no IP address in them.

The access logs are part of how the site is delivered. Rejecting analytics and browser privacy signals do not turn them off.

A link in one of our emails may include a short code, so we can tell that the link was opened. It does not tell us who opened it: a forwarded link, or one checked by an email security system, looks the same. We record the code, the page and the time. The site removes the code from your address bar when the page loads, and codes are deleted 90 days after the email is sent.

Optional analytics: what is recorded if you accept

Each page you open sends one small record. The site keeps the time and:

  • which page you opened;
  • the name of the website that linked you here (the site name only, never the full address). If you came from a webmail service, only its kind is kept, such as "Webmail (Gmail)" or "Webmail (other)", never the mail address of an organisation;
  • campaign tags from the link you followed, if it had any (the standard utm_ tags);
  • your type of device (phone, tablet or computer), your browser's name, such as Firefox or Safari, and whether your browser looks like an automated program, so that robots can be left out of the counts;
  • your approximate location: country and state or region, as estimated by the network that delivers the site. Your city is not recorded;
  • the two random identifiers described below.

If you click a link that leaves the site, one more record says where it went: email, LinkedIn, GitHub, or the name of the other website. The full address of the link is not kept.

The location comes from Amazon Web Services' delivery network, which estimates it from your connection. It is approximate and can be wrong. Our analytics records never contain your IP address, and the site does not store your full browser description in them either: it is reduced to the device type, browser name and automated-program flag above and then dropped.

What is kept in your browser

The site sets no cookies. It uses your browser's local storage instead, which is persistent storage for the same purpose: recognising your browser when it comes back. Avoiding cookies does not by itself make this private, so here is everything it keeps:

  • kd-consent, in local storage: your choice and when you made it, kept until you change your choice or clear the site's data. It is kept whether you accept or reject. An acceptance lasts 12 months; after that it is removed and the card asks you again.
  • kd-visitor, in local storage, only if you accept: a random identifier that recognises a return visit. It is replaced by a new one once it is 30 days old.
  • kd-session, in session storage, only if you accept: a random identifier for one visit, ended after 30 minutes idle or when you close the tab.
  • kd-utm, in session storage, only if you accept: the campaign tags from the page you arrived on, kept until you close the tab.

The identifiers are random codes, not linked to your name or email address.

Your choices

  • Accept analytics or Reject analytics on the card at the bottom of the page. Neither is chosen for you.
  • Privacy choices, in the footer of every page, reopens the card so you can change your choice. Choosing Reject stops all analytics sending at once and deletes kd-visitor, kd-session and kd-utm from your browser.
  • Global Privacy Control and Do Not Track are honoured as a rejection of the optional analytics. They control the optional analytics only, not the access logs. While your browser sends either signal, no card asks you, no records are sent to the analytics, any analytics identifiers are deleted, and analytics cannot be turned on. An earlier acceptance is withdrawn, not paused: if the signal is later turned off, the card asks you again and the analytics stay off unless you accept afresh.
  • Clearing this site's data in your browser removes everything listed above. With JavaScript turned off, no records are sent to the analytics; the access logs still record your requests.

Analytics records already sent before you reject are not deleted early. They hold no name or IP address, so we cannot tell which ones were yours; they expire with the rest.

Who serves the pages

The site is hosted by Amazon Web Services. Amazon Web Services processes your IP address and browser details to deliver every request, whether or not you accept analytics, and may keep them in its own operational systems under its own privacy terms. Request logging stays off where the site's files are stored; the access logs described above come from the delivery network. Amazon Web Services also reports a daily count of all requests, with no detail about who made them.

Where the data lives and who sees it

Analytics records are kept in a private, encrypted storage bucket at Amazon Web Services in the United States, and are deleted after 180 days. A copy is kept on the founder's own computer to build a summary, and it is deleted on the same schedule. The summary itself holds only totals, with no identifiers, and may be kept longer. The collector's own log holds no visitor data, only a short code for each refused request, and is kept for 14 days.

The data is seen by the founder only, Robert Klasen. He reads a private summary page that only he can sign in to. It shows totals, such as visits and page loads per day and pages viewed, and no identifiers or IP addresses. For the links in our emails, it shows the organisation we wrote to, the page, and when its link was opened. Nothing is sold, shared or used for advertising.

What the numbers cannot say

An opened link shows that the link was opened, not who opened it: it may have been forwarded, or fetched by a scanner. The campaign tags in our emails are the same for everyone who receives them. With only a few visits, the time and approximate region of a visit could still hint at who made it.

Email

If you write to admin@klasen-development.com, the message is received through Google Workspace and kept as ordinary business correspondence. It is read by Robert Klasen, who runs the company. Klasen Development does not sell or share your address or your message.

Other sites linked from this one, such as LinkedIn, GitHub and the public records on the work pages, have their own privacy policies.
