Check it yourself

This page does not ask you to trust us. It asks your own browser to prove that inyourbrowser.com keeps every file you process on your own device. Every check below works without opening developer tools.

1. Watch your browser stop a data request

The button below asks your browser to send a small piece of data to example.com. The browser refuses, because this site instructs it to refuse all outside requests. The actual message your browser returns will appear after you click.

Try to send data

Click the button below. It will ask your browser to send a request to a different website (example.com). The browser should refuse, because this site tells it to refuse all outside requests. You will see the actual error message your browser gave back.

2. See the live count of data leaving this page

This is the bigger version of the small indicator in the corner of every page. The left number is how many requests have left your browser since you loaded this page; the right number is how many were blocked. Both should be zero, unless you just clicked the demo above (in which case “blocked” will read 1).

Live network activity, from this page
requests left your browser
blocked by your browser

These numbers come from your own browser, not from us. They update live. The first number is how many requests this page has actually managed to send to another website. The second is how many your browser stopped from being sent. Both should usually be zero.

3. See what is stored on your device

The panel below reads directly from your browser, right now. It shows every cookie, every local storage key, and every database this site has put on your device. The list is almost always empty. There are at most two entries: theme (your light/dark preference) and nc_dismissed(whether you closed the floating “no data sent” pill).

What about the camera?

The QR code scannercan use your camera to scan QR codes in real time. The camera turns on only after you click “Start camera”. Video frames are decoded inside your browser and discarded immediately; nothing is recorded or transmitted. The same defences above apply to the camera stream.

What if you do not trust the buttons on this page?

Open your browser’s developer tools and check directly. The technical guide walks through the exact tabs, commands, and what each one means.
