What this site knows about you.
Almost nothing, and that is deliberate. This page states exactly what is collected, by whom, and why — in plain terms rather than boilerplate.

What HolterTek collects
Nothing. There is no analytics, no tracking pixel, no advertising network and no embedded third-party content of any kind. The fonts are self-hosted, the images are served from this domain, and the site makes no requests to any other host while you read it.
There is no account to create, no form to submit and no newsletter. The site does not profile visitors, and there is no data set anywhere that describes what you looked at.
Cookies
This site sets no cookies of its own. One cookie is set by Cloudflare, which sits in front of the site to serve it quickly and protect it from automated abuse:
| __cf_bm | Set by Cloudflare to tell automated traffic from human traffic. It holds a bot score, not an identity, and a separate one is generated per site — it cannot follow you from here to anywhere else. | Cloudflare~30 minutes |
|---|
That cookie is classified as strictly necessary: it exists to deliver a service you asked for — a working, non-abused website. Under the ePrivacy rules, strictly necessary storage does not require consent, which is why this site does not ask you to accept anything. There is nothing optional to accept.
The only thing stored on your device by the site itself is a single flag recording that you dismissed the cookie notice, so it does not reappear on every page. It contains no personal data and no identifier. Clearing your browser storage removes it and the notice returns.
Server logs
Like any website, this one is delivered by servers that keep short-lived technical logs. Cloudflare and Railway, the hosting provider, record the usual request metadata: IP address, timestamp, the page requested, and the browser's user-agent string.
An IP address counts as personal data, so it is worth being clear about it. These logs exist to serve pages and to detect abuse, they are not used to build any profile of you, and they are retained according to each provider's own policy rather than kept by HolterTek. The lawful basis is legitimate interest in running a secure, functioning site.
If you get in touch
If you email or call, whatever you send is used to reply and, should we end up working together, to run that project. It is not sold, not shared with anyone, and not added to any mailing list. Correspondence is kept for as long as it is useful for the work and ordinary bookkeeping, and deleted after that.
Your rights, and who to ask
You can ask what is held about you, ask for it to be corrected or deleted, or object to it being processed. In practice there will usually be nothing to send you unless we have corresponded. Ask at [email protected] and you will get an answer within a few days.
If you are not satisfied with how a request is handled, you can complain to the Norwegian Data Protection Authority, Datatilsynet.
