VisitLead tag cookie policy
Version of 4 November 2026.
This policy describes what the VisitLead tag stores in or reads from the browser of a person who visits the website of a VisitLead Customer. The Customer who installs the tag is responsible for informing its visitors; it may refer to this page from its own policy.
1. The principle
The tag recognises companies by their network, without a cookie. A cookie is only useful to recognise the return of a contact the Customer already knows. It is therefore only set if the rule for the visitor's country allows it, and never to identify an unknown person.
2. What the tag stores
| Name | Type | Purpose | Duration |
|---|---|---|---|
| _vl | First-party cookie of the Customer's website (SameSite=Lax, Secure) | Random identifier used to recognise the return of a contact known to the Customer | 12 months at most |
| _vl_oo | Browser local storage | Opt-out set by the "#visitlead-optout" link: when present, the tag no longer sends anything | Until the person clears the website data |
| _vl_c | Browser local storage | Consent choice passed on by the Customer's website | Until the person clears the website data |
The tag sets no third-party cookie and no advertising cookie, and reads no cookie belonging to another service.
3. When the _vl cookie is set
| Visitor's country | Rule |
|---|---|
| European Union, EEA, United Kingdom | Only after consent, read from the website's consent management platform (TCF v2, Cookiebot, OneTrust, Didomi, Axeptio, CookieYes, Usercentrics) or passed on by the website |
| Switzerland | Information and possibility to object, or consent if the Customer has chosen this setting |
| United States | Set, unless there is a Global Privacy Control or Do Not Track signal or an opt-out |
| Other countries | As for the European Union |
Everywhere, a Global Privacy Control or Do Not Track signal from the browser prevents the cookie from being set and forms from being read.
4. Without a cookie
Without a cookie, the pages of a single visit are grouped by a daily fingerprint, calculated with a secret that changes every day and is deleted after 48 hours at the latest. It does not make it possible to link two days or to recover the IP address.
5. Opting out
- Click the "Disable tracking" link (#visitlead-optout) offered by the website: the tag no longer sends anything from that browser and the _vl cookie is deleted.
- Enable Global Privacy Control in the browser.
- Refuse in the website's consent banner.
- To no longer be recognised as a contact by any VisitLead Customer: https://visitlead.io/en/optout.
6. Contact
Questions: hello@visitlead.io. Requests concerning a specific website are forwarded to the Customer that operates it.
The tag is published by Quantum Liquid LLC, 30 N Gould St, Ste R, Sheridan, WY 82801, United States of America.
