Cookie Policy
Last updated: May 2026
1. What is a cookie?
A cookie is a small text file placed on your device (computer, tablet, phone) when you visit a website. It enables the site to remember information about your browsing session in order to improve your experience or carry out audience measurement.
Under French CNIL guidelines (deliberation no. 2020-091 of 17 September 2020) and the ePrivacy Directive, certain cookies require your prior consent before being placed. Others are strictly necessary for the site to function and are exempt from consent.
2. Cookies used on bioxela.com
2.1 Strictly necessary cookies
These cookies are essential for the site to function. They collect no personal data for profiling purposes and do not require your consent under the ePrivacy Directive and CNIL guidelines.
| Name | Purpose | Duration | Type |
|---|---|---|---|
| bioxela_lang | Remembers the chosen language (FR/EN) | Session | First-party |
2.2 First-party analytics tracker
bioxela.com uses a first-party audience measurement tool hosted by BIOXELA on its own servers
(LWS, France). This tool does not place any cookie on your device: it relies
on a random session identifier stored in your browser's session memory
(sessionStorage),
automatically cleared when you close the tab.
| Identifier | Technology | Purpose | Duration |
|---|---|---|---|
| _bx_s | sessionStorage (not a cookie) | Links pages viewed during a single visit | Tab close |
Data collected: pages visited, referrer URL, UTM parameters if present in the URL, browser language, timezone, screen width.
IP address: used server-side to determine approximate location (city, country), then immediately anonymised (last octet set to 0) before any storage. The full IP address is never recorded.
Do Not Track (DNT): if your browser sends this signal, no browsing data is collected.
2.3 Social media and third-party cookies
The bioxela.com website contains a link to Alexandra TIZON's LinkedIn profile. This link opens in a new tab and places no cookies on your device from bioxela.com. The use of LinkedIn cookies is governed by LinkedIn's own privacy policy.
3. Consent management
bioxela.com does not place any consent-requiring cookie. The analytics tracker described in section 2.2 is exempt from prior consent under the CNIL guidelines for first-party audience measurement tools. No cookie banner is therefore displayed.
Should trackers requiring prior consent be added in the future (e.g. advertising cookies, social media embeds), a consent management mechanism will be implemented, allowing you to:
- accept or decline non-essential trackers before they are placed;
- update your choices at any time;
- withdraw your consent without this affecting your past browsing.
4. Browser settings
You can configure your browser at any time to accept or decline cookies, and delete those already stored. Please note that blocking certain cookies may affect the functioning of the site. Instructions for the most common browsers:
- Google Chrome — Menu → Settings → Privacy and security → Cookies and other site data
- Mozilla Firefox — Menu → Settings → Privacy & Security → Cookies and Site Data
- Safari — Preferences → Privacy → Cookies and website data
- Microsoft Edge — Menu → Settings → Cookies and site permissions
You may also opt out of certain trackers via the Your Online Choices platform (for advertising cookies from EDAA member companies).

6. Policy updates
This cookie policy may be amended at any time, in particular where regulations evolve or new tools are added to the site. The last updated date shown at the top of this page is authoritative.
