Website Privacy Policy

This website counts visits so its owner can see which work people actually look at. There is no cookie banner here because the site stores nothing on your device. Nothing is sold, shared with advertisers, or sent to an analytics company.

Who runs this

This site belongs to Bart Kelchtermans. Its analytics are collected with Umami, an open-source analytics package, self-hosted by Andrei Lavrenov on private infrastructure at umami.lav.ren. Stated precisely: the two of us are the only people who see this data. No analytics vendor, advertising network or data broker is involved, and no third-party scripts run on these pages.

Nothing is stored on your device

The tracker sets no cookies and writes nothing to localStorage, sessionStorage or IndexedDB. The only value it reads is the opt-out flag described below, and only if you set it yourself. Requests are sent with credentials: "omit", so no cookie travels with them. The EU cookie rule governs storing or reading information on your device — this site does neither, which is why you are not asked to accept anything.

What is collected

Pages you open (path, title and the referring URL); browser, operating system, device type, screen size and language; approximate location — country, region and city — derived from your IP address; loading performance (Core Web Vitals: LCP, FCP, CLS, INP, TTFB) and time on page; clicks on elements tagged for counting; and a recording of roughly one visit in seven.

Session recordings

About 15% of visits are recorded. A recording is not video and not a capture of your screen: the page structure and its text are re-serialised and replayed, which shows how the portfolio was browsed and where people lost interest. Anything typed into a form field is masked inside your own browser before it is sent, so the value never leaves your device. Click and scroll heatmaps are aggregates built from these recordings.

How a visit is identified

Each visit carries a one-way hash of your IP address, browser user-agent, hostname and site identifier. That hash cannot be reversed into an IP address and is not reused on any other website, so you are not followed across the web. Your IP address is processed to produce the hash and to resolve the approximate location above.

Stated plainly rather than marketed: an IP address is personal data under the GDPR, and a hash derived from one is pseudonymous rather than anonymous. The lawful basis for this processing is legitimate interest under Article 6(1)(f) — understanding how this site is used. You may object at any time.

Retention

Analytics records are kept until deleted by hand. No automatic expiry is configured.

Your rights

You may request access to data concerning you, request its erasure, or object to it being collected. Because a visit carries only an irreversible hash, your records generally cannot be singled out from anyone else's — which is the point of the design, and why the opt-out below is the dependable remedy. For anything else, write to [email protected].

Opt out

This sets one flag in this browser, on this device, which the tracker checks before sending anything. It is the only thing this site ever writes locally.
