Chrome Third-Party Cookies in 2025: Google’s April Decision Did Not End Tracking

Short answer: Google’s April 22, 2025 announcement did not make web tracking disappear, nor did it remove third-party cookies from Chrome. It said Google would not proceed with a planned Chrome-wide deprecation of third-party cookies or introduce a separate standalone choice prompt. For Chrome users, publishers, advertisers, privacy teams, and businesses that rely on browser-based measurement, the practical point was continuity: cookie controls remained available in Chrome settings, while tracking continued to involve many mechanisms beyond cookies.

What Google actually announced on April 22, 2025

Google’s statement was a change in direction for its Privacy Sandbox programme. The company said it would not deprecate third-party cookies in Chrome and would not roll out a standalone prompt about them. Instead, Google said users would continue to make choices through Chrome’s existing Privacy and Security settings.

That wording matters. A company announcement about a future browser policy is not evidence that third-party tracking had stopped, that every cookie setting had changed, or that websites had lost the ability to recognise visitors. It meant the broad plan to phase out third-party cookies in Chrome was no longer going forward in the form previously expected.

It also did not mean Google abandoned every privacy-related project. The announcement said Google would continue developing Privacy Sandbox technologies, although with a role different from the one originally contemplated, and would continue work on Incognito tracking protections. Google specifically referred to IP Protection as expected in the third quarter of 2025. At the April 22 dateline, that was a stated future plan, not evidence that the feature had already changed ordinary browsing.

the key distinction is simple: a decision not to retire a tracking technology is not the same as an instruction to accept it, and neither outcome makes tracking vanish. Browser privacy is a collection of settings, site practices, account relationships, device signals, network information, and advertising systems—not a single cookie switch.

Why tracking continued even without treating cookies as the whole story

Third-party cookies are small pieces of data that a browser can store for a domain other than the site a person is actively visiting. They have commonly supported cross-site advertising measurement, frequency capping, audience building, and personalisation. Their continued availability can make those uses possible where browser and user settings allow them. But removing or limiting them would not, by itself, erase the wider data ecosystem.

Sites can still use first-party cookies, which are set by the site a person visits directly. A retailer, news site, or streaming service may use them to preserve a signed-in session, remember language choices, retain a shopping basket, or measure activity on its own properties. These uses are not identical to third-party advertising cookies, and a useful privacy analysis should not collapse them into one category.

Other forms of recognition may include logged-in account data, identifiers transmitted by apps, information voluntarily supplied in forms, server-side analytics, referral data, and device or browser characteristics. Whether a particular technique is lawful or used by a particular service depends on facts, consent arrangements, jurisdiction, contracts, and implementation. The April announcement did not establish that every such method would be used, but it plainly could not establish that they had ceased.

Private-browsing modes should not be mistaken for a complete answer. Mozilla explains that private or incognito browsing primarily limits local retention of browsing history and cookies after a session closes; it does not hide activity from an ISP, employer, or school, and it does not by itself stop websites from identifying location or continuing advertising-related tracking without separate protections. See Mozilla’s explanation of what incognito browsing does and does not do. The same general lesson applies across browsers: local privacy controls and network privacy solve different problems.

A worked everyday scenario: researching a holiday

Consider someone researching a holiday over several evenings. They visit airline, hotel, map, restaurant, and review sites. On the first night, they accept or adjust cookie choices on some sites and sign into an airline account. On the second night, they return through a link in an email and compare prices from a workplace network.

Google’s April 2025 decision did not mean these visits became unlinkable. If third-party cookies were permitted in the browser, an advertising or analytics participant embedded across participating sites could potentially use them within its own setup. Separately, the airline could recognise the person through its first-party cookie or account login. Email links can identify the campaign that brought the visitor back. The workplace network may also create records under its own policies.

Now suppose the traveller uses a consumer VPN app on a café Wi-Fi connection. The VPN can encrypt the connection between the device and the VPN service and can make the destination site see the VPN server’s IP address rather than the café’s public IP address. That may reduce what the local Wi-Fi operator can readily observe and can alter the IP-based location signal presented to sites. It does not automatically prevent the airline from recognising a signed-in account, remove cookies already stored in the browser, erase information typed into forms, or stop a site from collecting data about interactions. A VPN also does not replace HTTPS, which protects the connection between the browser and a website.

The useful conclusion is not that privacy tools are pointless. It is that each tool has a defined scope. Cookie choices address browser storage and web relationships; account and permission choices address disclosed identity and app access; a VPN addresses part of the network path.

Browser controls, VPNs, and enterprise gateways are not interchangeable

A consumer VPN application has another role. It typically routes selected device traffic through a VPN provider’s server, protecting traffic against casual observation on the local network and changing the public IP address websites receive. In exchange, the VPN service becomes an important party in the connection path. Evaluating a service therefore involves its privacy policy, jurisdictional context, technical design, account requirements, payment practices, and clarity about logs—not just claims about anonymity.

An enterprise secure web gateway, corporate proxy, or employer-managed VPN serves a different purpose again. It may route staff traffic through company-controlled infrastructure for access control, malware filtering, data-loss controls, auditing, and compliance. It can protect a connection on an untrusted network, but it may also give the organisation visibility into traffic metadata or content where organisational policy and configuration permit. Workers should rely on their employer’s policies and approved tools rather than assume private-browsing mode or a personal VPN overrides workplace management.

Neither a consumer VPN nor an enterprise gateway fixes a compromised device. Malware, a malicious browser extension, or a phishing login page can defeat the assumptions people make about a secure network path. Sensible protection also includes software updates, strong unique passwords, multi-factor authentication where available, and careful handling of unexpected links.

The CMA process was separate—and October 2025 is later context

Google’s April announcement sat alongside a competition process in the United Kingdom, but the two should not be confused. The Competition and Markets Authority had examined whether Privacy Sandbox browser changes could harm competition, including possible effects on ad-tech rivals. Its framework included commitments from Google and monitoring by an independent trustee.

Competition oversight and individual privacy are related but distinct questions. A regulator may assess whether a platform change disadvantages competitors; a user may ask what data a website, browser, employer, ISP, or VPN service can observe. One question cannot fully answer the other.

Practical actions that do not depend on hype

• Review browser privacy and cookie choices periodically, particularly after browser updates or when using a new profile. Make changes with awareness that some sites may require certain storage for sign-in or checkout functions.
• Separate high-value activity where practical: use distinct browser profiles for work and personal use, and avoid staying signed into accounts unnecessarily when researching unrelated topics.
• Read consent prompts and privacy controls on sites that handle sensitive searches, purchases, health information, or financial activity. Declining optional advertising purposes may be more meaningful than relying on a single browser setting.
• Use HTTPS sites, keep the browser and device updated, and treat a VPN as a network-layer tool rather than an invisibility cloak. For choosing a service, see How to Choose The Right VPN.
• On work or school devices and networks, assume monitoring and management rules may apply. Use approved channels for sensitive organisational activity.

What the available evidence does not establish

The April 22 Google statement does not prove how every website configured cookies, how every advertising company processed data, or what any individual user saw in Chrome. It does not demonstrate that Privacy Sandbox APIs produced a particular privacy or competition outcome. It does not establish that IP Protection had launched at that date. And it does not show that a VPN makes a person anonymous, blocks all tracking, or protects an infected device.

Takeaway: Google’s April 2025 decision preserved the existing Chrome approach to third-party-cookie choices rather than making tracking disappear. Treat browser controls, account choices, HTTPS, and VPNs as complementary tools with different limits—and keep later regulatory outcomes separate from what was known on April 22.
