Comscore Opt Out: ScorecardResearch, VoiceFive, and Privacy Choices

Comscore provides several privacy choices for data associated with its browser tags, mobile identifiers, and market-research programs. Its Data Subject Rights page lets a person choose among opt-out, deletion, access, and sensitive-information options. The current privacy policy also warns that the browser choice is cookie-based and must be repeated for other browsers or devices. This guide explains the separate routes and their limits.

Quick facts

How to opt out of Comscore

1. Open Comscore’s Data Subject Rights page and choose the request type that matches your goal.

2. For browser or tag participation, select the relevant market-research or targeted-ad choice.

3. Add a mobile device identifier only when you want the request to include that device.

4. Submit access or deletion separately if you want a report or erasure request.

5. Repeat the browser choice on each browser and device that you use.

What the choice changes

Comscore distinguishes a browser-based market-research choice from access and deletion. The page may ask you to certify that you are the sole user of the device associated with the browser or identifier. Keep the request details and the browser used.

Verification checklist

• Save the confirmation page, email, ticket, or request date.
• Record whether the choice covered a browser, device, app, IP address, email, or formal privacy request.
• Do not assume that an advertising preference also deletes historical data or partner copies.
• Repeat the route only where the provider says the identifier or environment is separate.

Reappearance and reset risk

Deleting cookies, blocking them, switching browsers, or changing devices can remove the signal that records the opt-out. A new mobile identifier also has a different scope. Recheck after browser maintenance or a device replacement.

Privacy-rights requests versus advertising choices

An advertising preference, deletion request, access request, correction request, and account or app removal are different actions. Pick the narrowest route that matches your goal, then read the provider’s confirmation language. A provider may need to verify identity or the identifier before handling a broader request. This article is practical guidance, not legal advice.

If the provider’s page changes

Privacy interfaces move. Start from the provider’s current privacy center or policy rather than an old form copied into a search result. Check the legal name, the purpose of the request, the identifier requested, and the expected verification step before submitting anything. If the old route redirects, follow the current first-party navigation and do not enter sensitive information into an unrelated page.

Frequently asked questions

Does opting out of Comscore stop every ad?

No. These choices generally change personalization or the use of a selected identifier. Ads, measurement, contextual content, or activity tied to another browser or device can continue.

Do I need to repeat the request?

Often yes when the choice is stored in a cookie, device setting, mobile advertising ID, IP address, or another identifier. Keep the original confirmation and repeat only for the new scope.

Does this delete old data?

Not automatically. Use the provider’s access or deletion route when you want a broader privacy request, and follow any identity or identifier verification it requires.

Can I use a privacy signal?

Some providers describe Global Privacy Control or industry opt-out tools. Treat those as a separate signal and check the provider’s current scope and jurisdiction language.

What should I do after submitting?

Keep the request details, wait for the provider’s stated processing or verification behavior, and recheck the same browser, device, app, or profile without submitting personal information again.

What this control changes

An opt-out changes how Comscore may use an identifier for interest-based advertising. It does not necessarily erase every record, stop every advertisement, or remove information held for security, measurement, fraud prevention, or a service you asked a company to provide. Read the confirmation page carefully and keep a copy of the date, device, browser, and request type.

Before you submit a request

• Use the same browser, phone, connected-TV profile, or advertising identifier that you want to change.
• Turn off private browsing for the submission if the form needs to set a confirmation cookie.
• Record the confirmation message or reference number without sending unnecessary personal details.
• If you manage several devices, repeat the device-level choice on each one.

How to verify the result

Wait for the processing window stated by the Comscore privacy or request page, then revisit the preference page on the same device. A successful opt-out is usually shown as a saved choice, a confirmation screen, or a message that the identifier is no longer eligible for targeted advertising. If the result is unclear, submit a privacy-rights request rather than guessing that an advertising cookie was deleted.

Why an opt-out can appear to stop working

These choices are commonly tied to a browser cookie, mobile advertising identifier, account, IP address, or connected-device profile. Clearing cookies, changing browsers, resetting a mobile advertising ID, installing a new TV, or switching networks can create a new identifier. The service can therefore appear to contact or recognize you again even when the earlier choice was processed correctly. Recheck the preference after a reset and keep the original confirmation for comparison.

Privacy rights are separate

If your goal is access, deletion, correction, restriction, or a copy of personal data, use the separate privacy-rights route offered by Comscore. An advertising opt-out generally limits a use of data; it is not automatically a deletion request. Submit only the minimum information needed to locate the relevant record and follow any identity-verification instructions on the official page.

Practical checklist

• Save the official URL and the date you completed the choice.
• Repeat the choice for each browser or device where the identifier differs.
• Avoid treating fewer personalized ads as proof that all data was erased.
• Recheck after cookie deletion, an app reinstall, or a device reset.
• Use the provider’s access or deletion route when you need a data-rights response.

Keep a simple record of the change

A short record makes follow-up easier: note the official page, the device or browser used, the date, and the confirmation wording. Do not include passwords or unrelated identity documents. If a provider asks for verification, use only the fields required by its own privacy process. This record helps distinguish a processed preference from a new identifier created later by a browser reset, app reinstall, or device change.
