Cookie policy
This policy explains which cookies and storage technologies are used on this site. As things stand, the site sets none that require consent: this page therefore describes as much what does not happen as what does.
1. What a cookie or tracker is
A cookie is a small file placed by a site on your device and read again on your later visits. Other techniques have the same effect: local storage (localStorage, sessionStorage), invisible pixels, device fingerprinting.
Article 82 of French Law no. 78-17 of 6 January 1978 as amended makes any operation to access or write information on your device subject to your prior consent, except where its sole purpose is to enable or facilitate an electronic communication, or where it is strictly necessary to provide an online communication service at your express request.
2. This site’s position: no cookies set
As at the date this policy was last updated, this site sets no cookies, neither its own nor any third party’s.
- no audience-measurement or analytics cookie;
- no advertising, retargeting or campaign-measurement cookie;
- no social-network cookie, no embedded share button;
- no A/B testing, no heatmap, no session recording;
- no request to any third-party server when a page loads: the typeface is served by the site itself and the map is loaded only at your request.
That is why you are shown no consent banner: there is nothing to consent to. A banner that collected no meaningful consent would add nothing but friction.
3. The only item stored: your language preference
When you choose a display language, that choice is stored in your browser’s local storage so that the site appears in that language on your later visits.
| Item | Type | Purpose | Duration | Consent |
|---|---|---|---|---|
| coroni_locale | Local storage (localStorage) — first party | Remember the display language chosen by the visitor | Persistent until erased by the visitor | Not required — exemption under Article 82 |
This item is strictly necessary to provide a service you expressly requested — displaying the site in the language you chose. It contains only a language code, does not identify the visitor, is read by no third party and never leaves your browser. It falls within the consent exemptions accepted by the CNIL (the French data protection authority).
You can delete it at any time by clearing your browser’s site data; the site will then revert to the language inferred from your browser preferences.
4. The location map, loaded only on your click
The contact section shows the postal address on its own and embeds no map by default. A map is loaded only if you press the dedicated button, whose label states what that action triggers.
Loading it calls the OpenStreetMap mapping service. At that moment, and only at that moment, your IP address and your browser’s technical characteristics are disclosed to that service, which may set its own cookies or storage items under its own domain. Those operations fall under the responsibility of the OpenStreetMap Foundation and its own privacy policy.
Your click constitutes consent to that single load; it is not remembered and must be repeated on each visit. You can read the address, open it in the mapping service of your choice or telephone us without ever loading the map: that route remains fully available.
5. Cookie table
The table below lists the cookies actually set by the site. It is empty today and must be filled in, row by row, before any tracker goes live.
| Cookie name | Publisher / domain | Purpose | Type | Retention period | Legal basis |
|---|---|---|---|---|---|
| No cookie to date | — | — | — | — | — |
To be filled in only once a tracker is actually set. A table announcing cookies that do not exist is as inaccurate as a table omitting cookies that do.
6. Consent mechanism and withdrawal
No consent mechanism is needed as things stand, apart from loading the map, which requires your explicit action and takes effect only for the current visit.
You remain in control of your browser’s storage and may, at any time, clear site data, block cookies or accept only those of sites you visit directly. Those settings are in your browser’s privacy preferences, under the heading for cookies and site data. Blocking local storage entirely does not prevent you from reading the site: only the language memory stops working.
The "Do Not Track" signal and any privacy preferences your browser sends are contradicted by no tracking device, since this site has none.
7. If trackers are introduced later
Adding audience measurement, an automatically loaded map, an embedded video or an advertising conversion tool would change the position described above. The following obligations would then apply:
- obtain consent before anything is set, other than strictly necessary trackers or audience measurement configured to meet the exemption conditions published by the CNIL;
- make refusing as easy as accepting, through a refuse button of the same prominence and legibility as the accept button;
- allow consent to be withdrawn at any time, by a means easily accessible from every page;
- keep proof of the consent obtained, and retain the recorded choices for no more than six months, in line with the CNIL’s recommendation;
- complete the table in section 5 and the list of processors in the privacy policy before going live.
8. Contact and complaints
Any question about this policy may be sent to contact@coroni.fr or to Coroni Security Systems Installation, 128 rue Véron, 94140 Alfortville, France.
You may also lodge a complaint with the Commission nationale de l’informatique et des libertés (CNIL), 3 Place de Fontenoy, 75007 Paris — www.cnil.fr. The details are set out in the privacy policy.
