You entered the date once. That’s the reminder.
Most reminder apps ask you to type the reminder — which means the one that mattered is the one you never typed. Hundo works the other way: the maturity date on your FD, the renewal month on your policy, the expiry on your passport are already in the record, so the reminder is a view of data you gave once, not a chore you repeat. Add the policy, and its premium is already on the calendar.
