Browser fingerprint spoofing · 100% local

Tracking you today?
Nah, not today.

They don't need cookies to recognize you. Your browser quietly hands every site a unique fingerprint — your GPU, your fonts, the way your screen draws a single pixel. NahNotToday buries all of it under persistent noise, so trackers see a stranger that still behaves like a real browser.

The problem

Cookies were the easy part.

You cleared cookies. You went incognito. You turned on a VPN. And the tracking network still greeted you by name — because none of that touches the fingerprint.

Every browser leaks dozens of tiny technical signals. Alone they're harmless. Combined, they form one stable hash that's unique to your machine — and it follows you across sites, sessions and even private windows. Ad blockers can't help: there's no cookie to block. The ID is your browser.

NahNotToday doesn't hide the signals. It rewrites them — consistently — so the math never resolves to you.

Core spoofing

Persistent noise on every tracking vector.

Not random per request — that screams "tampered". NahNotToday locks one believable, noisy identity per session, so you look like a consistent real user the whole time you browse.

Canvas

Subtle, stable noise injected into every canvas read — so the rendered-pixel hash never matches anyone else's.

noise: persistent · per-session

WebGL

Spoofs vendor & renderer strings (e.g. NVIDIA → Intel) without breaking 3D — your GPU stops being a beacon.

renderer: spoofed

AudioContext

Masks the unique signature of your audio stack so the silent "audio fingerprint" trick comes back empty.

signal: masked

Fonts

Hides which fonts you actually have installed — a quietly powerful identifier most blockers ignore entirely.

enumeration: blocked

Client Rects

The sub-pixel size and position of page elements — read through getClientRects — quietly betrays your exact font rendering. NahNotToday adds steady geometry jitter, so those measurements never single you out.

geometry: jittered
one-click profiles

A whole new identity, generated in one click.

Press one button and NahNotToday assembles a complete, internally consistent profile — GPU, fonts, screen resolution, locale and time zone, all matched to a real OS-and-browser pairing. Every detail agrees, so there's no telltale mismatch for trackers to flag.

GPU

A believable vendor & renderer for the chosen OS.

FONTS

The font set that real OS actually ships with.

RESOLUTION

A common screen size for that class of device.

LOCALE

Language & time zone that read as one region.

you stay in control

Or fine-tune every value by hand.

Prefer to dial it in yourself? Override any field and NahNotToday holds it steady — perfect for matching your VPN exit node.

USER-AGENT

Choose your reported browser & OS string.

LANGUAGES

Override the languages your browser advertises.

RESOLUTION

Report a common screen size, not your exact one.

TIME ZONE

Align your zone with your VPN for full consistency.

How it works

Protected in three clicks.

No accounts. No configuration marathon. Install it and you're already harder to track.

01

Install & pin

Add NahNotToday from the Chrome Web Store and pin it. That's the whole setup. Defaults are already sane.

02

It spoofs, silently

One consistent noisy identity is generated for your session and applied to Canvas, WebGL, Audio and fonts automatically.

03

Browse normally

Same noise all session long — so sites don't flag you as a bot. Hit a site that breaks? Whitelist it in one click.

Inside the extension

Simple on the surface. Serious underneath.

One popup tells you exactly what's being spoofed right now. No dashboards, no noise — well, only the good kind.

Beyond the fingerprint

The leaks a VPN forgets about.

You can hide your IP and still leak it. NahNotToday closes the two gaps people most often miss.

Third-party cookies, blocked

The cross-site cookies that stitch your browsing into one profile? Cut off at the source — without nuking the first-party cookies that keep you logged in.

WebRTC leak protection

WebRTC can quietly reveal your real IP behind a VPN. NahNotToday disables it, so the connection that's supposed to be private actually stays that way.

Receipts, not promises

Verified against the tools trackers use.

We didn't just say it works — we ran it through the same fingerprinting test suites the tracking industry relies on. Go check for yourself.

Zero trust issues

A privacy tool that you don't have to trust.

The irony of most "privacy" extensions: they phone home. NahNotToday can't betray your data to a server, because there is no server. Everything happens inside your browser, on your machine, full stop.

  • 100% client-side & local
    No cloud processing. The work never leaves your device.
  • No servers
    Nothing to breach, subpoena, or quietly sell.
  • No logs
    We don't record where you go. We literally can't.
  • No telemetry
    No "anonymous usage stats." No data collection of any kind.
Questions

The honest FAQ.

Almost never — because the noise is consistent, sites see a stable browser rather than one that mutates mid-session. On the rare site that's picky, one click adds it to your whitelist and spoofing is bypassed just for that domain.

That's exactly why the noise is persistent, not random. Tools that re-roll values on every request raise tampering flags instantly. NahNotToday holds one believable identity per session — which is why it scores 92% trust on CreepJS.

No. There are no servers, no logs, and no telemetry. Everything runs locally in your browser. A privacy extension that harvested your data would be a bad joke — so we built it so that it can't.

They solve different problems. A VPN hides your IP address; NahNotToday hides your browser's identity. Together they're strongest — set your spoofed time zone to match your VPN exit node and the story lines up perfectly.

No meaningful impact. The spoofing hooks are lightweight and run only when a site reads a fingerprinting API — which is most of the time exactly the sites you'd want it running on anyway.

Yes — free to install and use, with no premium tier holding the real protection hostage. If it saves your sanity, there's a Support button below. Entirely optional, deeply appreciated.
