Privacy
Is this actually private?
Yes. Detection runs 100% on-device. We never see, store, or transmit your screen content or browsing history.
What exactly does my ally see?
A short text that something happened. Never screenshots, never URLs, never what it was. They can also see whether each of your devices is standing guard and when it was last seen. That's it.
Does On Guard save screenshots?
No. Never. Detection runs on your device and the pixels stay there. We never upload, store, or see your screen. If needed, your ally gets a short check-in text, never an image.
Getting started
Do I need an account to start?
Yes: you sign in during the two-minute setup. Your account is what links your devices and settings.
Which devices does it cover?
iPhone, iPad, Android, Mac, Windows. One subscription, unlimited devices.
Does On Guard work on iPhone?
Yes, but with key differences. Apple does not allow our detection engine on iOS, so On Guard on iPhone uses a Safari content filter plus block and nudge modes. Mac, Windows, and Android run the full real-time engine.
Will it drain my battery?
No. Typical impact is under 1% per day. It only activates when it needs to.
How it works
How is this different from a blocker?
Blockers use DNS lists, so they miss everything slipping through your social feeds. On Guard interrupts content in real time across every app and browser, and what it sees never leaves your device.
What stops me from just uninstalling it?
Nothing. You stay free to remove it. But On Guard is tamper-evident: if you turn defense off, uninstall it, or it goes quiet on a device, the contacts you chose get a text. Quitting loudly is the point.
Trial and billing
What if it doesn’t work for me?
30-day free trial, then a 30-day money-back guarantee. Cancel in one click: no forms, no calls.

Each install and feed-reset guide ends with its own questions — the ones that only make sense on that platform.
