1. What are cookies
Cookies and similar technologies such as localStorage store information in your browser. Under Article 22.2 LSSI, anything not strictly necessary requires your prior consent.
2. What we actually use
| Category | Needs consent? | Set by | When |
|---|---|---|---|
| Necessary | No | ProtoVision | Always |
| Analytics (GA4) | Yes | Only if you accept Analytics | |
| Marketing (YouTube) | Yes | Google / YouTube | Only if you accept Marketing and a video is loaded |
Before you choose, no Analytics or Marketing cookies, scripts or iframes are loaded.
3. Details
3.1 Necessary
| Name | Purpose | Duration | Type |
|---|---|---|---|
pv_consent | Remembers your choice in the banner (analytics/marketing, version, date). Stored as a cookie and in localStorage under the same name. | 12 months | First-party |
This is strictly necessary to respect your choice and is not used to track you across sites.
3.2 Analytics — Google Analytics 4 (only with consent)
After you accept Analytics we load https://www.googletagmanager.com/gtag/js. No request is made before consent, and no analytics data is sent before consent.
| Name | Purpose | Duration | Provider |
|---|---|---|---|
_ga | Distinguish users | 2 years | |
_ga_<id> | Keep session state for this property | 2 years |
3.3 Marketing — YouTube (only with consent)
YouTube shows a placeholder first. Only after you accept Marketing do we create an <iframe> to youtube.com or youtube-nocookie.com. YouTube’s privacy-enhanced mode (youtube-nocookie.com) still involves a connection to Google/YouTube when the video is loaded.
When the video is loaded, your browser connects to YouTube/Google and may send technical information such as IP address and user-agent.
| Name | Purpose | Duration | Provider |
|---|---|---|---|
VISITOR_INFO1_LIVE | Estimate bandwidth and player preferences | ~6 months | YouTube |
YSC | Distinguish views in the same session | Session | YouTube |
PREF | Player preferences | ~8 months | YouTube |
YouTube may use additional technologies and the exact cookies can vary with its current implementation.
4. Your choice
- Banner: Reject all, Customize and Accept all are shown with equal prominence and require the same interaction. Closing the banner without choosing, continuing to browse or scrolling does not grant consent.
- Manage cookies: the footer link “Manage cookies” reopens the banner, lets you change categories and switch from granted to denied. Withdrawing consent prevents future non-essential loads.
- Already sent data: withdrawing consent stops future collection; it does not automatically delete data already sent to Google. You can delete cookies in your browser and, for Google, manage data in your Google account.
- Duration: your choice is kept for 12 months, then we ask again.
5. Managing cookies in your browser
You can also block or delete cookies in your browser settings (Chrome, Firefox, Safari, Edge). For Analytics you can use the GA opt-out add-on.
6. Recipients and transfers
Necessary: only ProtoVision and hosting for delivery. Analytics/Marketing: Google as described in privacy §5.
7. Updates and contact
If we add new cookies we update this table and ask for consent again where the purpose changes. Questions: info@protovision.es.
