What is browser fingerprinting?
Browser fingerprinting combines observable browser or device characteristics to distinguish visitors. It can work without a login or a conventional tracking cookie. “No account” and “no fingerprinting” therefore describe different properties.

What can become part of a fingerprint?
Signals can include browser and operating-system details, language, time zone, screen characteristics, supported fonts, or graphics behavior. Individually ordinary values can become more distinctive in combination. Fingerprints are not necessarily stable or uniquely identifying.
A cookie stores an identifier that the browser sends back. Fingerprinting attempts recognition from characteristics instead. Deleting cookies does not automatically change all those characteristics.
Why this matters for AI chat
A service can avoid accounts while still keeping network or usage records. The prompt itself may contain identifying information. Evaluate what is collected, what is retained, and why, instead of treating an empty sign-up form as a complete privacy audit.
Practical controls
Use maintained browsers with built-in tracking protection and review extensions that can read pages. An incognito window is not a promise that the browser is indistinguishable from others or that the destination cannot see your network address.
For nokeep, read the privacy policy’s operational-data explanation alongside its browser-local history design. Free quotas and abuse prevention are distinct from saving the text of a conversation. Protecting the content archive does not remove every trace of a website visit.

Asked before you asked
Does a VPN stop browser fingerprinting?
It can change the network address seen by the destination, but it does not automatically change browser characteristics or information in your prompt.
Does no sign-up mean untrackable?
No. Network information, browser signals, payments, and the content you provide are separate considerations.
