Due Keeper

`Due Keeper helps you track renewals, return windows, document expiries, service dates, and follow-up tasks on your device. Add an item with a due date, choose an earlier reminder date, keep one next task, reschedule when dates change, and delete stale task text without losing the underlying date. When notification permission is granted, the app can schedule a local alert before the due date and another on the due date. You can also share or export a user-controlled checklist from Today. No account, developer server, tracking SDK, advertising SDK, or cloud sync is required. Due Keeper organizes dates only and does not provide legal, immigration, tax, insurance, financial, or professional advice. Notifications are best-effort local reminders; if notifications are disabled, silenced, delayed, or removed by iOS, you may miss a date.
