Definition
The ‘Opt-out by default’ setting designates data collection without a request for visitor consent.
As of the web user’s first event, they are identified as a visitor with the placement of a cookie, and personal data may be transmitted.
When using this configuration, as with any digital platform, you must provide, in a clear and explicit manner, a method enabling visitors to choose opt-out.
Important
You may only implement this solution if the legislation in effect for your platform does not require prior consent for the online collection of personal data.
Please refer to your legal team to ensure that the platform in question authorises the use of opt-in by default prior to any implementation.
Expected behaviour
To comply with your users’ wishes, you must be able to modify the state of consent at any time of the visit.

All cookies are defined with the OPT-OUT value. |
Tag configuration
The ‘Opt-in by default’ method will use the Tag Composer Privacy plug-in available in the Javascript 5.24.0 version.
Note
This plug-in and its methods will apply solely to client-side visitor identification, it will impact first-party cookies only.
Tagging
Opt-In
var tag = new ATInternet.Tracker.Tag();
tag.privacy.setVisitorOptin(); // Visitor set under Opt-In
tag.page.set({
name: 'pageName',
});
tag.dispatch();
Opt-Out
var tag = new ATInternet.Tracker.Tag();
tag.privacy.setVisitorOptout(); // Visitor set under Opt-Out
tag.page.set({
name: 'pageName',
});
tag.dispatch();
IIt is possible not to send information by using the false setting of Tracker sendHitWhenOptOut.
Properties
The ‘opt-in by default’ setting uses two dedicated consent properties:
-
Consent properties
The new Privacy plug-in methods add 2 properties to your hits:
- Visitor mode : visitor_privacy_mode / &vm to filter events based on the consent status (optin/optout)
- Consentement visiteur : visitor_privacy_consent / &vc to directly identify consented traffic when ‘true’
Explorer
Once the marking and the hits containing the properties have been implemented, you will only see events in opt-in visitor mode.
You do not need to filter the 2 properties; we will do this for you. (See below).
Analyse Privacy
In Explorer you can reach Audience > General Traffic > Privacy to see the number of events considered as opt-out.
When the visitor has opt-out status, their hits are anonymised, excluded from general traffic and serve only to feed this analysis.
Data Query / Data Flow
You may add the Visitor mode and Visitor consent properties to your data sets.
You will be able to analyse opt-in visitor mode only, given that opt-out events feed the Privacy analysis exclusively.
