How DeskSip Uses Your Webcam Without Compromising Your Privacy

Does This Extension Watch Me?

It's the first question anyone should ask before granting a Chrome extension access to their webcam. And it's the right question. Extensions that abuse camera permissions exist. Spyware exists. Skepticism is healthy.

So let's answer it directly: DeskSip uses your camera to detect when you take a sip of water. That is the only thing it does with the camera. No video is recorded. No frames are uploaded. No data leaves your machine. Ever.

What Actually Happens

When DeskSip's detection runs, everything stays on your device. The camera feed is processed locally, the sip is detected locally, and a count is stored locally in Chrome's storage on your machine. Nothing is transmitted anywhere. There is no server receiving your video. There is no backend processing your face.

The rest of the extension, your nudge history, your daily goal, your streak, all of it lives in Chrome's local storage. It never touches a network connection.

No other part of the extension touches the camera either. The popup, the settings page, the notification system — none of them have camera access. The detection runs in an isolated, sandboxed component whose only job is to watch for a sip and increment a counter.

The Network Question

A reasonable follow-up: sure, the detection is local, but couldn't the extension still phone home with metadata?

No. The detection pipeline makes zero network requests. There is no telemetry attached to it. No event is fired to an analytics service when a sip is logged. DeskSip's free tier has no analytics or usage tracking of any kind.

You can verify this yourself. Open Chrome DevTools, go to the Network tab, and watch while DeskSip is running. You will see nothing coming from the detection side of the extension. The only network activity you would ever see from DeskSip is if you sign up for a Pro account, and that is entirely separate from the detection system.

How to Verify It Yourself

You do not have to take my word for it. Chrome gives you the tools to check.

Open chrome://extensions, find DeskSip, and click "Details." You can see exactly which permissions the extension has declared. Nothing is hidden. You can also inspect the extension's source files directly from that page if you want to go deeper.

You can revoke camera access at any time. Go to Chrome settings, find DeskSip under extensions, and remove the camera permission. The detection stops immediately. Nothing is cached, nothing is queued, nothing lingers.

The Practical Reality

I built DeskSip as a solo entrepreneur. Even if I wanted to store your video, I couldn't. The cost would be financially impossible for a one-person operation. That's not me.

But more importantly: I never wanted to. The whole point of building DeskSip was to create a tool I would actually trust and use myself. A tool that spies on you is not that.

The Privacy Guarantee

The camera answers one question: did you just take a sip? The answer stays on your device. Nothing more.

Your camera permission is yours to give and yours to take back. Try it.
