PRISM is useful for people who want to know what a website is doing before they hand over an email, a credit card, or a photo. It is also useful for privacy lawyers, compliance staff, journalists, and anyone who has to write a report about what a particular site collects from its visitors.
You paste a web address into PRISM. PRISM opens a small private browser window on your machine, loads the page, and records every request the page tries to make. Then it compares each request against a built-in list of 3,107 known trackers (from the DuckDuckGo Tracker Radar dataset, published under an open license). You see the results in plain English: which trackers fired, who owns them, what category they belong to, and a count of how many were on the page.
A list of every tracker on the page, grouped by category (advertising, analytics, fingerprinting, session recording, social, content, customer success, and a few others). For each one you see the company that owns it, the type of data they typically collect, and how common that tracker is across the public web.
PRISM does not block trackers. It is a scanner, not a blocker. If you want blocking, install uBlock Origin or a similar browser extension. PRISM also cannot see trackers that only fire after you click a specific button or fill in a specific form (some trackers only activate on user interaction). PRISM tells you about every tracker that fires when the page first loads.
PRISM ships in two versions. Both run on your device. Both keep your data local.
Full scan, full tracker list, full results on screen. Local history of past scans. Auto-updating tracker database. No limits on how many sites you can scan.
Everything in Free. Plus PDF audit reports for client work. Batch scan many sites at once. Compare two scans of the same site side by side. Scheduled scans that run on their own.
PRISM does not send scan results, analytics, or any user data to Cinderpoint. The only outbound traffic is the request that loads the page you asked to scan. PRISM does not check for updates on its own; the App Store handles app updates, and the tracker list refreshes when a new app version ships. Advanced users can build a tracker list file from the DuckDuckGo Tracker Radar open-source dataset and import it through Settings.

PRISM is built on Electron, React, and TypeScript. The tracker database comes from DuckDuckGo's Tracker Radar (published under the Apache 2.0 license). All of PRISM's bundled open-source dependencies are credited in the NOTICE file shipped inside the app.
Version 1.0 is built and tested. Store submissions in progress. Sign up below to be notified when PRISM goes live in your store.
