Support

Write to support@pipeguard.app — a real person reads it, usually answering within two business days.

What to include

The app version (Settings → the version line at the bottom), your phone model, and what you expected to happen. In Settings there is Send feedback, which attaches the app version, the platform and the in-app log to the message — it tells you exactly what is being sent before it goes, and it can attach a picture of the screen you were looking at if you switch that on.

The evening warning did not arrive

Warnings are scheduled by the phone itself, so a phone that was switched off cannot ring — the app says so when you turn warnings on. Some Android phones restrict apps in the background and delay or drop their alarms; Settings → Notification reliability shows when this phone does, and where to change it. If the app could not check the forecast for a day and a half, it tells you so with a notification instead of staying silent.

How is the risk calculated?

From the forecast low, the hours the forecast spends at or below the pipe threshold (about −4 °C / 25 °F — a little above where research puts the first freezing, on purpose), the wind, and the answers you gave about the house. Thresholds are deliberately conservative: when in doubt, drip.

Where does the forecast come from?

From the US National Weather Service for homes in the US and from MET Norway everywhere else — both public services, named in Settings → Forecast sources.

A pipe is frozen right now

Open the app and tap “A pipe is frozen?” — the steps are there, and they work before you have set anything up: keep the tap open, shut off the main if you suspect a split, warm the run gently and never with an open flame, photograph everything, call a plumber. Each step you tick is logged with its time.

Can I change the 8 pm hour?

Yes — Settings → Warning time. The warning arrives around that hour, not to the minute.

Is this a guarantee?

No. It is guidance based on a forecast and your answers, not a promise about your pipes.

Refunds

Purchases are handled by the store, so a refund is requested there — and the two stores work differently, which is worth knowing before you write to anyone.

On Android: Google Play → Order history → Report a problem. If Play declines and you believe the app is at fault, write to us: a Play purchase is one we can refund ourselves, and we would rather do that than argue.

On iPhone and iPad: reportaproblem.apple.com. Apple issues every App Store refund and a developer has no way to return an App Store payment — we cannot refund you there, and it would be dishonest to promise it. Write to us anyway if the app is at fault: we will tell you exactly what to put in the request, and fix the defect.

Privacy
