Not signing in removes the account session you chose not to use, but it does not make a visit invisible. A platform may still receive technical details such as your IP address and browser information, plus activity such as searches or videos viewed. Those signals do not, by themselves, prove that the platform knows your real name.
What changes when you don’t sign in?
Many services allow some use without an account. Google, for example, says people can use services such as Search and watch YouTube videos while signed out. That avoids directly attaching the visit to an account session you did not use, but Google says it may store signed-out information with identifiers tied to a browser, application, or device (Google Privacy Policy).
That is the key distinction: an account-linked record is not the same thing as a browser- or device-linked record. A service may recognize or group activity using technical identifiers without the cited policy establishing that it has identified the visitor by real name.
What can a platform receive during a visit?
Network and device details
Google lists information such as IP address, browser and device details, operating system, request date and time, and the referring page among the data it may collect when people use its services. The IP address can provide network-level or approximate location information, but it is not proof of a particular person’s identity (Google Privacy Policy).

Searches, viewing, and other activity
Google’s listed activity data includes search terms and videos watched. A platform can use activity received during a signed-out visit to operate or personalize its service, subject to its policies and settings. A policy describes what may be collected; it does not prove that every listed signal is recorded on every visit.
Cookies and similar identifiers
Platforms may use cookies or similar technologies associated with a browser or device. TikTok’s U.S. Privacy Policy, last updated July 15, 2026, describes technical and usage information, cookies, and approximate location derived from network or device information. It also describes partner-provided information about activity outside TikTok’s services (TikTok U.S. Privacy Policy).

TikTok’s global Website Cookie Policy, accessed October 4, 2026, gives examples of differing cookie durations: a ttwid analytics cookie may last up to 13 months, a ttp advertising cookie one year, and Google Analytics retention 24 months. These are examples in that policy, not a universal schedule for all cookies, visitors, or jurisdictions (TikTok Website Cookie Policy). TikTok says some cookies are essential; blocking all cookies may impair functionality.
Can a website track you without an account?
It can receive information about a visit without using an account login. The Federal Trade Commission’s privacy FAQ, for example, says its own website collects visitors’ IP addresses, visit date and time, browser software, and operating system. The FTC also notes that some of its sites use cookies and that third-party services are separately operated under their providers’ policies (FTC Privacy Policy FAQ).

A visit to a platform directly is not the only way information may reach a platform. Meta’s April 16, 2018 explanation says it receives information when people use websites or apps that use Meta services, including when they are logged out or do not have a Facebook account. This is a dated explanation of embedded-service data flows, not proof of current behavior for every Meta product (Meta: Data and Advertising).
Does incognito hide you from websites?
Do not treat incognito or private browsing as a way to hide a visit from the platform receiving it. It changes the browser context in which you visit, but the policies described here still identify information a service may receive from a request, such as an IP address, browser details, or activity. The sources cited here do not establish that private browsing prevents those services from receiving such signals.

What does a platform’s policy establish—and what doesn’t it?
- It establishes what the company says it collects or may collect. The details vary by platform, service, geography, settings, and the type of visit.
- It does not establish that every signal is collected every time. A policy’s categories are not a visit-by-visit record.
- It does not prove that a signal names a person. An IP address, cookie, or device identifier can be useful for recognizing or grouping activity, but the cited policies do not show that any one of these identifies a visitor by real name.
- It does not settle what can be linked across visits. Whether activity can be associated depends on the service and its identifiers, settings, network, geography, and other information available to it.
What can reduce optional tracking?
Where a service offers cookie choices, declining optional cookies can reduce that category of collection, but it does not prevent a site from receiving the request itself or necessarily disable essential cookies. Cookie controls also differ by service and jurisdiction. For precise location, TikTok says collection can depend on device settings and permissions; its policy also describes approximate location based on information such as IP address and SIM region.
For the question “what can a website see if I’m not logged in?”, the practical answer is: it can still receive visit-related technical and activity signals, and an embedded third-party tool may receive information too. That is different from proof that the platform knows who you are by name.
