Two kinds of nudge, both optional.
In Settings › Preferences you can be reminded to refresh your values monthly or quarterly. The reminder arrives on the first of the period, mid-morning.
Separately, the app can warn you before something runs out — an insurance policy, a fixed deposit maturing, a warranty ending. These come from the dates you enter on your records, and the same list drives the Upcoming Dates report.
Reminders are scheduled locally on whichever device you set them up on, because WorthSafe has no server to send them from — which is also why the app needs no account and holds none of your data. If you use both an iPhone and a Mac and enable reminders on each, you will get one from each.
Set the cadence to Off, or turn WorthSafe's notifications off in iOS Settings. If notifications are denied at the system level, the app tells you rather than silently failing.
