Cookie policy

This page describes the use of cookies and third-party data on kaineos.es. Last updated: 3 September 2026.

What we store in your browser

We do not use cookies. We store three values in your browser's local storage: a record that you've seen this notice (localStorage, kept until you clear it), a random session identifier (sessionStorage, cleared when you close the tab) and a random browser identifier (localStorage, kept until you clear it).

Neither identifier holds personal data, and neither tells us who you are. The browser identifier does let us tell that several visits come from the same browser, so we can distinguish a returning visitor from a first-time one. Clearing this site's data in your browser removes it, and that link with it.

Usage measurement

We measure site usage with our own tooling, with no third-party products such as Google Analytics, Meta Pixel or Hotjar. We record the page visited, the referring page, the language, the device type (mobile, tablet or desktop), the browser family (for examplechrome or safari, or the crawler name when the visit is automated, derived on our server without storing your full browser string), the approximate country (derived from your IP, which we do not store), campaign parameters in the URL (utm_source and similar), how long you spend on each page, some relevant interactions (for example, opening a label in detail, how far you zoom into it and how long you look at it, or copying our email address) and the identifiers described above. When you submit the contact form we also store your browser and a cryptographic hash of your IP, from which the original IP cannot be recovered.

This data is stored with Supabase, our database provider, on servers located in the European Union, and is used only to understand which content works and to handle your request. It is never sold or shared for advertising.

Third-party data

We load the Manrope typeface from Google Fonts. This involves a connection to Google's servers, which receive your IP. We do no advertising and do not share data with third parties for commercial purposes.

Your control

You can delete saved preferences at any time by clearing the site's storage in your browser. If you reject external font loading, the site keeps working with your system's default typeface.
