ads-personalised-consent

A client side package to provide consent settings of personalised advertisement.

Functionality Overview

This package collects all the information related to privacy and generates an answer on whether different types of personalised advertisement is allowed. It takes into account of:

• The privacy policy of the location which the user is in (e.g. California Consumer Privacy Act (CCPA) for California, US), which is collected from Privacy Legislation Client
• The browser settings - e.g. Global Privacy Control (GPC).
• The consents settings for behavioral, demographic and programmatic ads retrieved via the FTConsent cookie. Users can configure these settings via the Manage Cookies page in FT.com, the Manage Cookies page on the FT App and the Manage Cookies pages on the specialist titles websites. These values can also be configured via the Cookie Banner displayed on FT.com, FT App or specialist titles. Yet another way to configure ads consent is via the Privacy page on FT.com

Use

Typical usage would be to add the module to your app, call the imported method and then check whether the personalised advertisement is allowed:

import { getPersonalisedConsent } from "@financial-times/ads-personalised-consent";

async function onPageLoad() {
  // create a fresh, updated instance of PersonalisedConsent, and get the privacy properties via getters
  const pc = await getPersonalisedConsent();
  const personalisedConsent = pc.isAllowed();
  // check whether a certain type of personalised ads is allowed or not
  if (personalisedConsent.behavioral) {
    setupBehavioralAds();
  } else {
    blockBehavioralAds();
  }
  
  // alternatively, only update the privacy legislation properties and retrieve the new values
  await pc.updatePrivacyLegislation();
  const legislation = pc.getLegislation();
  const region = pc.getRegion();
  // similar for GPC value and consent cookie
  pc.updateGpcValue();
  const gpc = pc.getGpcValue();
  pc.updateConsentCookie();
  const consentCookie = pc.getConsentCookie();
  ...
}
