Current browser status

You successfully changed your status to OPTED {{ optout.isOptedOut ? "OUT" : "IN" }}

Your browser currently does NOT have a unique ID5 User ID

Your browser currently HAS a unique ID5 User ID

I would like to {{ optout.isOptedOut ? "Opt In" : "Opt Out" }}:

  • If you select "Opt Out with Id5 User ID":
    • If you are in a cookie supporting browser:
      • ID5 will set a non-unique opt-out cookie in your browser to store your choice.
      • On non-ID5 websites, this cookie will be considered a “third-party cookie” and may not be readable by us if your browser is blocking or not supporting third-party cookies. If we cannot read the opt-out cookie that we have set, and you indicate on the website you are visiting that you want us to process your personal data, we may not be able to honor your choices.
      • If you block or delete the ID5 opt-out cookie, and consent again for your data to be processed by ID5, we might not know that you previously opted out.
    • If you are not in a cookie supporting browser, ID5 will leverage our probabilistic algorithm to attempt to identify your browser and save your preference.
      • On non-ID5 websites, ID5 will also process some data that does not allow us to directly identify you in an attempt to identify your browser again and honor your opt out preferences. If we still process any pseudonymous personal data about you, it will only be for the purpose of respecting your choices; we will never assign you an ID5 User ID for use in advertising purposes.
      • Since we rely on our probabilistic algorithm, which never uses any personally identifiable information, we may not always be able to recognize your browser, and therefore may assign a unique ID5 User ID that does not have the opt out preference associated with it. By enabling third party cookies, we can ensure that your browser’s opt out preference is always respected within this browser.
  • If you select "Opt Out with Email", this will indicate to our partners and us that you no longer wish to receive targeted advertising based on your email. ID5 will not process your personal data for any requests linked to your hashed email address. Note: this choice may limit your ability to access ad-supported content.
  • If you select “Opt In with User ID”, you agree to ID5 processing your data and might enable our partners to more efficiently serve you relevant ads. This does not overwrite any consent settings you may select on other websites.
  • If you select “Opt In with Email”, this will indicate to us and, potentially our partners, that you agree to receive targeted advertising based on your email.
If you live in the EEA and have chosen to block ID5 on a non-ID5 website, then ID5 will honor your choice regardless of your opt out choices set here. For more information about how ID5 uses your data, please read ID5’s Platform Privacy Policy.

If (a) you have not opted out and (b) we are not required to obtain your opt-in consent to process your personal data, an ID5 User ID may be assigned to your browser after your visit to the ID5 Privacy Preference Center, even if you have not elected to opt in.
