The Do Not Track (DNT) header is a small signal that your browser can send to every website you visit. It tells the site that you prefer not to be tracked - in other words, you don’t want your browsing activity to be collected, shared, or used to build a profile about you across different websites.

How DNT Header Works

• The DNT header is sent as part of the HTTP request when your browser connects to a site.
• It can have different values:
  
  • 1 = “Do not track me.”
  • 0 = “It’s okay to track me.”
  • Not set = No preference is given.

This makes it a way for users to express their privacy preference to websites.

Limitations

• Voluntary compliance: The biggest limitation is that most websites are not required to respect this header. Many simply ignore it.
• Not a blocker: Unlike ad blockers or privacy tools, the DNT header doesn’t stop tracking on its own. It just communicates your request.
• Inconsistent support: Some sites and services honor it, but many do not, so its effectiveness is limited.

In short: The Do Not Track header is like politely asking websites not to track you. But whether they actually listen is up to them.

Why It Matters

Even though DNT is weak (due to lack of enforcement), it still adds a signal. When combined with other browser data, it can help form a fingerprint or profile.

Relevance to Kameleo

While some websites respect a user’s preference and limit or remove tracking, many others disregard it because it is not legally enforceable in most jurisdictions. This is precisely why Kameleo offers the ideal solution. Do Not Track behavior in Kameleo profiles is kept consistent and aligned so it does not produce mismatches that could reveal automation or fingerprinting.
