Criteo Opt Out Guide: Browser, Mobile, and Privacy Rights

To complete a Criteo opt out in a web browser, open Criteo's official browser-disable page in that browser and use the control shown there. Criteo says this deletes its cookies from the current browser, stops consent-based collection, and stops consent-based Criteo ads in that browser. The choice is browser-specific. Repeat it in every browser profile, device browser, and independent in-app webview you use.

Advertising choices do not remove public people-search listings. Run a free exposure scan for that separate task, and use the opt-out guide hub to organize browser choices and record-removal work.

How to opt out of Criteo

Criteo official browser-disable page explaining browser scope, processing time, webviews, and cookie reset risk — Criteo's official browser-disable page, checked on August 18, 2026; no preference or personal request was submitted.

Use the browser in which you want the preference to apply. Privacy extensions, strict cookie settings, and Safari protections can affect whether the page can store or read the dedicated choice cookie. If the official page cannot confirm the choice, follow Criteo's browser-specific alternative instructions rather than changing unrelated privacy settings permanently.

Open the official browser-disable page in the browser profile you want to cover.
Read the status shown for that browser, then activate the disable control if Criteo is enabled.
Wait for the page to show the completed or disabled state and record the date.
Repeat the operation in every other browser, browser profile, device, and relevant in-app webview.
Return after 24 hours to confirm the state and check again after cookie clearing or major system updates.

What the browser choice changes

Criteo describes three effects for the current browser: its cookies are deleted, consent-based personal-data collection ends, and consent-based Criteo ads end. The page also notes that data collected before the choice may still be processed where Criteo relies on legitimate interests. This is why a browser advertising choice and a formal privacy-rights request should not be treated as identical actions.

The same scope distinction appears in the OpenX opt-out guide and PubMatic opt-out guide: a browser signal covers one environment, while mobile advertising identifiers and formal rights use other routes.

Cover mobile apps and webviews

A mobile browser choice does not automatically cover every app. Criteo warns that an app can display a separate webview that behaves independently from both the normal browser and the app's advertising environment. Open the official page from the affected environment when possible, and also review the device operating system's advertising and privacy settings.

If you use several devices, keep a small checklist by device and browser. Include work and personal profiles separately. This prevents a successful desktop choice from being mistaken for coverage on a phone, tablet, or another user profile on the same computer.

Verification, timing, and troubleshooting

Verify in the same browser

Return to the browser-disable page without switching browser profiles. A confirmation in Chrome does not establish the state in Safari, Firefox, Edge, private windows, or an embedded webview. Save a dated screenshot of the page's status without submitting personal information.

Allow the stated processing window

Criteo says its ads should stop as soon as possible and no later than 24 hours. Seeing an ad after that time does not by itself prove the choice failed because another advertising company may have delivered it. Verify the provider status first, then check whether the affected browser retained its cookie.

Recover from a reset

If the page shows Criteo enabled again, repeat the choice. Common triggers include clearing all cookies, using privacy software that removes the dedicated cookie, updating the operating system, creating a new browser profile, or replacing the device. Record the trigger so future checks focus on the environments most likely to reset.

When to use Criteo's privacy-rights route

Use the Your Rights route when your goal is broader than stopping consent-based advertising in one browser. Depending on your location and request, that can include access, deletion, objection, or other statutory choices. Criteo may need information to locate the relevant data and verify that the request belongs to you. Provide only what the official form requires.

For a broader cleanup sequence, pair the data broker opt-out list with the guide to removing personal information from the internet. Advertising preferences are one layer of that plan, not a substitute for public-record removal.

A useful privacy log has one row for each environment. Record the provider, browser or webview, device, action, visible status, date, and next review trigger. Do not store sensitive identifiers in an unprotected note. For formal requests, keep the provider's reference number and the minimum information needed to match the response. This structure makes it clear whether an unexpected ad appeared in the covered Chrome profile, a different phone app, or an embedded view that never received the original choice.

When troubleshooting, start with scope before repeating every action. Confirm the exact browser profile, then inspect the page status and recent cookie or operating-system changes. If the status remains disabled, the ad may come from another provider or from a context outside Criteo's consent-based service. If the status changed, reapply the choice and record the reset. This sequence produces better evidence than assuming that all advertising activity has one source.

Review the log every few months and after major browser changes. Rechecking does not require submitting a new rights request when the existing provider status is still visible and correct. It simply confirms that the technical browser preference survived. Only escalate through the official rights route when the intended action is broader, the provider cannot recognize the relevant data, or a verified request has exceeded its applicable response process.

Criteo opt-out FAQ

Does the Criteo opt out stop all ads?

No. It changes Criteo's consent-based activity in the covered browser. Other companies can still deliver ads, and Criteo's page distinguishes its services from the wider advertising ecosystem.

Do I need to opt out in every browser?

Yes. Criteo tells users to repeat the operation across browsers and devices. Treat separate profiles and independent app webviews as separate environments too.

How long does the Criteo opt out take?

Criteo says it stops displaying its ads as soon as possible and within 24 hours at the latest. Separate external environments can have different timing.

Can clearing cookies undo the choice?

Yes. Criteo stores the choice in a dedicated browser cookie and says deleting it can remove the remembered preference. Revisit the page after clearing cookies.

Is a browser opt out the same as deleting my data?

No. The browser page describes a service and consent choice. Use Criteo's privacy-rights route when you want to request access, deletion, or another broader right available in your jurisdiction.
