A browser extension that watches every request a web page makes and reports, in plain English, which companies received your visit — ad networks, fingerprinters, session recorders — and what they likely collect.
Blockers like uBlock or Ghostery remove trackers silently — useful, but you never learn what was actually happening. DataFlow does the opposite: it blocks nothing and shows everything. Every page gets a grade from A to F, every third party gets named and explained in one sentence, without jargon.
It runs entirely on your device. There is no server, no account, and the extension sends no data anywhere — an extension about surveillance shouldn't do any.
0 € — forever
3.99 € / month or 19.99 € / year — cancel anytime
Pro history is computed and stored only on your device, like everything else.
Data collection: none. The DataFlow extension does not collect, transmit, sell, or share any user data. All network-request analysis happens locally in your browser. The browsing history used for Pro insights is stored only on your device (browser local storage) and can be deleted at any time from within the extension. The extension operates no server and makes no requests to us.
Payments. Pro subscriptions are processed by ExtensionPay and Stripe on their own pages. Payment details never pass through the extension. Their privacy policies govern payment data.
