Common questions
How are days counted?
Between returns a signed number of calendar days and selected working weekdays, excluding the end date. Reversing the dates gives a negative result. Add and Subtract support days, weeks, months, years, and working days.
Does it skip holidays?
No. Choose your working weekdays; holidays on those weekdays still count. Verify important deadlines independently.
What happens at month-end?
Month and year operations use the last valid day when the original day does not exist in the target month. For example, January 31 plus one month becomes February 28 in a non-leap year.
How do I restore access or cancel?
Use Settings → Restore Purchases while signed into the original store account. Manage subscriptions in Apple or Google Play subscription settings. Deleting the app does not cancel a subscription.
Where is my data?
Saved items stay on this device. Uninstalling or clearing app data removes local items. Device backups may retain copies. There is no cloud sync or app account. Keep separate exported copies of important data.
