A free trial is a period when you can use an app with all its features before paying. It exists so you can find out whether the app fits your day before you spend anything.

Why it matters

A trial is not the same as a refund. A trial is time before you buy. A refund window is time after you buy. Some products offer one, some both.

How NotchStar’s trial works

Every install gets 7 days with every tool turned on. The count starts at the first launch and is in whole days. If the clock on your Mac is set backwards, that counts as day zero, not as extra time. During the trial the app contacts no server.

When the 7 days pass, the app asks for a license key to keep the notch open. The trial end is a soft wall. It never deletes your data, and it never locks it. The home page also runs every tool in your browser, so you can try them before you install anything.

Limits

The trial is counted from the first launch on your Mac, using that Mac’s clock. After it ends, a license key is the way to keep using the notch.

To see the price model, read one time purchase. Try the Timers tool during your trial, and see how one time purchase notch apps compare.
