Opt-Out

Ariane Hervier
  • Updated

  • Definition

    Opt-out translates the user’s choice not to be tracked and consequently designates, for Piano Analytics, a collection of anonymous data.

    On all platforms (website or mobile application, etc.) using an Analytics solution, it is a legal requirement to provide a clear opt-out option.  

     


    Expected behaviour

    Piano Analytics uses properties and cookies geared towards visitor and user identification.

    If you use our markers, you must also use our methods to enable opt-out status.

    They will define the opt-out values of all identification or cookie settings, in order to ensure the non-collection of this data by our servers.

    Our marking methods are based on client-side or server-side cookie management.

    Both forms of cookie management have their own opt-out method (see below).

    Only these hit parameters will be filled in:

    s idclient vm vc ts
    site number visitor identifier visitor mode visitor consent hit timestamp

     

    These parameters will feed the AT Internet Privacy analysis, allowing you to get an anonymous and quantitative view of your traffic generated by users refusing tracker deposit. More details in our developer documentation.

     


    Client-side cookie management

    Description

    As client-side cookie management is handled by JavaScript, only your marking is able to define the cookies and opt-out of the requesting visitor.

    On your site, you simply add a button to activate the method in the example provided below.

     


    Tag Configuration

    This method requires SmartTag JavaScript v5.24.0 minimum.
    Its configuration requires the use of Client-side user ID and Privacy plugins.

    Tagging

    var tag = new ATInternet.Tracker.Tag();
tag.privacy.setVisitorOptout(); //  Visitor is set to Opt-Out status 
tag.page.set({
    name: 'pageName',
});
tag.dispatch();

     

    Server-side cookie management

    Description

    Server-side cookie management uses our servers (xiti.com, ati-host.net, etc.), your site cannot define the opt-out value of visitor cookies.

    Visitors choosing to opt out of our analytic solutions must complete a dedicated form, by clicking on your site to reach our opt-out page.

    The marker example described below opens a browser window to enable the user to complete the form, authorising the placement of a cookie to memorise their opt-out choice.

     

    Note

    Server-side cookie management for opt-out implies that the cookie is defined on a domain other than your site. Our opt-out cookie is therefore a 3rd party cookie.

    With opt-out via this form, the visitor is on opt-out status for all other sites using our server-side cookie management.

    These opt-out cookies may be blocked by browsers. Please refer to the browser restrictions on cookies.


    Tag Configuration

    This method requires SmartTag JavaScript v5.21.0 minimum.


    Tagging

    function optOut() {
    window.open('http://xiti.com/en/opt-out');
    ATInternet.Tracker.Tag({
       disableCookie: false
            });


    Non-transfer of a hit in opt-out

    You can prevent the marker from sending hits when the visitor is deemed ‘opt-out’.

    There are two ways for you to do this:

    • Unclick the dedicated option in the advanced settings of your configuration

    • Use the dedicated method in the following marking:
      It is possible not to send data by overloading the tracker using the method:
    sendHitWhenOptOut:false


    Management of application identifiers

    Our audience measurement SDK for your applications meet the same requirements as websites relative to the use of trackers.

    If identification is not stored on a cookie or application, it is stored and must benefit from an opt-out option as for websites.

    Please refer to the dedicated articles in our developer documentation:
