You think you are browsing anonymously.
Here is what this page just learned about you.
No cookie, no account, no consent. Just by loading this page. Any website does the same — most of them use it to recognise you from one visit to the next.
None of this leaves your browser. No server receives this data: there is no server. You can cut your connection and reload — the page still works.

Shrinking your fingerprint
Ordered by what actually works, not by what is popular.
What a VPN does not do
A VPN hides your IP address from your internet provider and from the sites you visit. It changes nothing about everything listed above: your browser fingerprint stays identical, and it is the fingerprint that lets a site recognise you across the web. Two people behind the same VPN remain perfectly distinguishable.
It is useful, but it replaces neither a browser that resists tracking nor a content blocker. VPN advertising often suggests otherwise.
Is private browsing enough?
No — and you can check it yourself in a minute: open this page in a private window and compare the results. They will be the same.
Private browsing clears what is stored on your machine — history, cookies, form entries — when you close the window. It changes nothing about what your browser answers when asked: installed fonts, graphics card, resolution, time zone. That answer is your fingerprint, and it is identical in both modes.
