Page Peek

Page Peek - See what a page collects about you

Ever wonder what's happening behind the scenes when you visit a website? Page Peek reveals the tracking signals active on any page you visit - in real time.

With a single click, see a clear breakdown of:

Third-party scripts loaded from external domains
Known trackers and advertising networks
Cookie and storage access (cookies, localStorage, IndexedDB)
Fingerprinting techniques (canvas, WebGL, audio, font enumeration)
Tag managers like Google Tag Manager, Adobe Launch, Tealium, and Segment
Each site gets a privacy score from 0 to 100 based on what was actually observed - not assumptions or blocklists. Page Peek distinguishes between first-party and third-party activity so you can understand the full picture.

Why install Page Peek?

Stay informed about what data collection happens during your browsing
Spot fingerprinting and tracking you wouldn't otherwise notice
Compare how different sites behave
Lightweight and fast - observes passively without slowing down your browsing
No data leaves your browser. Everything is processed and stored locally

What Page Peek does NOT do

It does not block ads, scripts, or trackers
It does not modify page content or interfere with how sites work
It does not send your data anywhere - all analysis happens locally on your device
It does not make assumptions about intent - it only reports what it directly observes
Page Peek is an awareness tool, not a blocker. It shows you what's happening and lets you draw your own conclusions. Pair it with your ad blocker or privacy tool of choice for a complete picture of how sites behave before and after blocking.
