Clean up
the internet.

On Guard catches sexualized posts as they load, on your device, and you clean them up with one tap.

Illustration: a wall of feed posts. As you scroll, each sexualized post on it is caught as it loads, covered by a nudge, and replaced by a clean post. Nothing is uploaded.

The algorithm doesn't care about you.

It only wants your attention.

It finds what stops your thumb and serves more of it, usually late and usually when you are alone. Blocking a list of sites never reached the feed. Losing those small fights in private wears a man down, and the feed keeps training him for the next one.

Stop the algorithm.

Detection runs on your device. A nudge covers dirty content, and "Move on" removes it.

Your data and screenshots stay on your device. We never sell it, and never send it to the cloud.

Someone in your corner.

Choose people you trust as allies. If adult content is open on one of your devices, they get a text with the app, the device and the time. Never a screenshot, never your history.

“I needed a tool to help avoid temptation online, but I didn't want screenshots sent to some server from my laptop and phone. On Guard keeps me sharp without compromising my privacy.”
Caleb R. Software engineer
“Wasted years on nofap forums, counting streaks, posting confessions. Kept relapsing anyway. On Guard did more for me in a month than any of it. Finally locking in on my goals.”
Devon K. Business owner
“I've watched porn since I was a kid. Seems like no one knew about the problem, or no one cared. Getting On Guard stopped the habit cold. I finally feel like the father and husband my wife and kids deserve.”
JP S. Husband and father

Your trial starts in the app.

Mobile subscriptions are billed through the App Store or Google Play. Mac and Windows use web checkout. Renewal, cancellation and applicable refund terms are shown before you subscribe.

Questions, answered.

Is this actually private?

Yes. Detection runs in the background on your device, not on the cloud. Your browsing history is not collected. If you choose to send a screenshot after a false alarm, that image goes to On Guard for review. Account, settings, subscription and check-in data are handled separately.

Does it work the same on iPhone?

Not quite. For app store compliance, iPhone uses Apple’s Screen Time controls for site filtering and nudges in the apps you select. On Guard does not run visual detection on other apps on your iPhone.

What exactly does my ally see?

A check-in names the app, device, and time when adult content is opened on a supported device. It never includes the site, screenshots, or your browsing history.

What happens when I tap "Move on"?

Wherever possible, On Guard triggers the platform’s own negative signals to remove the content and prevent more of it from being pushed to your account. Elsewhere, "Move on" closes the content, or recommends alternative content. The illustration above uses a clean post to show the idea of moving on.

How does billing work?

The trial lasts 30 days. The annual plan is $99.99 per year; the monthly plan is $9.99 per month. Your purchase screen shows the renewal date and the terms for your billing provider before you subscribe.
