Not signing in removes the direct association with the account session you chose not to use; it does not make a visit invisible. A platform may still receive technical details and activity signals, such as an IP address, browser or device information, and the searches or videos involved. Those signals do not, by themselves, prove that the platform knows your real name.
What changes when you do not sign in?
The platform does not have the account session you would have used to associate that visit with your signed-in account. Google, for example, says many services—including Search and watching YouTube videos—can be used while signed out. It also says signed-out information may be stored with unique identifiers tied to a browser, application, or device (Google Privacy Policy).

So the distinction is not “tracked” versus “untracked.” It is account-linked activity versus activity that may still be associated with a browser, app, device, network, or other signals. What a service actually collects on a particular visit depends on the service and circumstances; its policy describes categories it may collect, not a receipt proving what happened to one visitor.

Network and device signals
A request to a service can include information such as an IP address, browser or device details, operating system, request time, and the page or link that referred you. Google lists these kinds of information among the data it collects when people use its services. The FTC gives a concrete example from its own website: it says it collects visitors’ IP addresses, visit date and time, browser software, and operating system (FTC website privacy FAQ).

An IP address is a network signal, not proof of a person’s name. It may help indicate approximate location or a network, but the cited policies do not establish that an IP address alone identifies a named viewer.
Cookies and browser or device identifiers
Some services use cookies or similar identifiers associated with a browser, app, or device. Google describes identifiers for signed-out use. TikTok’s U.S. Privacy Policy, last updated July 15, 2026, describes technical information, cookies and similar technologies, and activity-related information collected when people use its services (TikTok U.S. Privacy Policy).

TikTok’s website cookie policy gives examples of retention periods: a ttwid analytics cookie may last up to 13 months, a ttp advertising cookie lasts one year, and Google Analytics data retention is listed as 24 months. These are examples stated in that policy, not a schedule that applies to every cookie or platform. The policy also says some cookies are essential and that blocking all cookies may impair functionality (TikTok Website Cookie Policy).

Searches, views, and other activity
Technical details are not the only possible signals. Google lists searches and watched videos among activity information that can be collected in service use. TikTok’s U.S. policy also describes usage information and information provided by partners about activity off TikTok. A policy listing a category does not establish that every item is collected for every visitor or that it is attached to a real-world identity.

Approximate location
Location may be estimated from network or device information. Google includes IP addresses among possible location inputs. TikTok’s U.S. policy names IP address, SIM region, and device settings as inputs to approximate location; more precise or additional location collection may depend on device permissions. Approximate location is not the same as a confirmed home address or a known identity.
Can a website track you without an account?
It may be able to receive or use visit signals without an account session. Cookies or device-linked identifiers can help a service recognize a browser or device, and activity can be recorded in connection with service use. Whether signals are linked across visits—or connected to a particular person—depends on the service, settings, browser, network, geography, and other information available to it. The policies cited here describe possible data flows; they do not prove a particular visitor was identified by name.

What if you visit a third-party page instead?
A page on another website may load a platform’s tools, such as embedded content or other services. That is different from visiting the platform directly: the third-party page may transmit information to the service whose tool it uses. Meta’s April 16, 2018 explanation says it can receive information when people visit websites and apps that use its services, including people who are logged out or do not have a Facebook account. That dated explanation describes an embedded-service data flow; it should not be read as proof of current behavior for every Meta product (Meta explanation of data from other websites and apps).

The FTC likewise notes that some of its sites use cookies and that third-party services are separately operated under their providers’ policies. A site’s own privacy policy may therefore not describe every service loaded on its pages (FTC website privacy FAQ).

Does incognito hide you from websites?
Do not treat private or incognito browsing as a way to hide from the platform you visit. It is a browser mode, not a no-data request: the platform can still receive information sent when its page or service loads. The evidence cited here does not establish the exact behavior of every browser’s private mode, so check your browser’s own documentation for what it does with local history, cookies, and session data.
Quick Recap
What can you do to reduce some signals?
- Review cookie choices. Where a service offers controls, decline optional cookies or adjust preferences. Some cookies may be essential, and blocking all cookies can disrupt features; TikTok’s policy notes this trade-off.
- Limit app permissions. If you use an app, review whether it has access to location services and revoke permissions you do not want it to use. Network-derived approximate location may still be possible.
- Consider embedded content. A third-party page can load services from another platform, so visiting it may involve more than the site named in the address bar.
- Use account controls when account separation matters. Signing out avoids using that active account session, but it does not guarantee that visits cannot be associated through other signals.
