Privacy and Opt-Out

The Irish Market build of the Nielsen SDK automatically Opt's Users out of the collection of any User Identifiable information or any Device Advertising ID.

When building your app:

  1. Ensure that you are using the NoID version of the Nielsen SDK Framework.
  2. Immediately following the initialization of the Nielsen SDK ensure you call the userOptOut API with Opt out selection:
NielsenAppApi?.userOptOut("nielsenappsdk://1"); // User opt-out

Retrieve current Opt-Out preference

Whether the user is opted out via OS-level Opt-out or via User Choice Opt-out, the current Opt-Out status as detected by the SDK is available via the optOutStatus property in the Nielsen SDK API

@property (readonly) BOOL optOutStatus

Display OptOut Notice

Nielsen does not use cookies in measurement in Ireland; however, you may want to present this information to your user. Sample code on how to do this is below:

Sample Code

import UIKit
import WebKit
import NielsenAppApi

class OptOutVC: UIViewController, NielsenAppApiDelegate, WKNavigationDelegate {
    var nielsenApi : NielsenAppApi!
    var webView: WKWebView!
    override func loadView() {
        webView = WKWebView()
        webView.navigationDelegate = self
        view = webView

    override func viewDidLoad() {
     // For English use: https://sites.nielsen.com/priv/browser/cookie-policy-ie-en.html
     // For  Gaelic use: https://sites.nielsen.com/priv/browser/cookie-policy-ie-ga.html

            if let url = URL(string: "https://sites.nielsen.com/priv/browser/cookie-policy-ie-en.html") {
                webView.load(URLRequest(url: url))
                webView.allowsBackForwardNavigationGestures = true

        func closeOptOutView() {
            self.dismiss(animated: true, completion: nil)
