Personal data

The website has no forms, no user accounts and no comments. You are never asked for any personal data.

Analytics

To see which pages are read, the website uses Koko Analytics, a tool installed directly on the site, with no external service. It sets no cookies on your device, does not store your IP address and shares no data with third parties. Only aggregate counters are recorded: number of visits and pageviews, pages viewed and referring sites. This data cannot identify you and is deleted after 25 months.

You can opt out of this measurement. Your choice is saved in your browser, only to remember your refusal, and applies until you clear it.

Your visits are currently counted, anonymously. Stop counting my visits

Cookies

The website sets no analytics or advertising cookies. It only uses technical cookies needed for it to work: remembering your chosen language and, when needed, a security cookie from the hosting provider that protects the site against attacks. These cookies do not require your consent.

Hosting

The website is hosted by LWS, a French hosting provider. Like any host, LWS may keep technical logs (IP address, date, page requested) to keep the service secure.

Your rights

Under the GDPR, you can ask to access, correct or delete data about you by writing to serge.dao@sdtconcept.fr. You can also lodge a complaint with the CNIL, the French data protection authority (www.cnil.fr).
