Our cookie policy and how we use them

Last reviewed: 9 October 2026Version: 1.2

This document does not constitute individualised legal advice.

1. What cookies are

Cookies are small files that a website stores on your device. They may be strictly necessary for the operation of the site or serve other purposes (analytics, personalisation, advertising).

2. Cookies used by alethexis.com

Alethexis uses only cookies and storage that are strictly necessary to provide the service you request. None of them requires prior consent.

We do not use advertising, analytics, third-party tracking or profiling cookies.

3. Analytics

Alethexis does not perform visitor analytics and does not use audience-measurement tools on alethexis.com. For that reason the site displays no consent banner: there are no non-exempt cookies or technologies to consent to. Should a non-exempt technology be introduced in the future, prior consent will be requested, with accepting, rejecting and configuring made equally easy.

We use the browser's local storage (localStorage and sessionStorage) to remember functional interface preferences, such as having dismissed the newsletter notice or the last sign-in method used. It is not used for tracking or profiling purposes, nor is it shared with third parties.

The electronic-communications rules apply to any access to or storage on the device, whether a cookie or local storage: the exemption depends on the purpose, not the technique.

4. How to manage cookies

You can configure your browser to block or delete cookies. Please note that blocking strictly necessary session cookies may prevent you from signing in and using the platform.

5. Further information and contact

For further information on the processing of your data, see the Privacy Policy. For any enquiry: [email protected].
