Email info@thebighead.ca and tell us your iPhone model, your iOS version, and what you expected to happen. That is usually enough for us to reproduce it straight away.
Yes. If you are not signed in to iCloud, or you turn iCloud off for Kalend, the app keeps working normally on that device — you simply do not get sync between devices. Nothing is lost.
On your device, and — if iCloud is enabled — in your own private iCloud database. There is no Kalend server. We cannot see your data, which also means we cannot recover it for you. See the privacy policy.
The Calendar tab needs full calendar access. Check Settings → Privacy & Security → Calendars → Kalend. If it is set to "Add Events Only", Kalend can create events but cannot display them — switch it to Full Access.
Only so it can show your real events beside the tasks due that day. Your events are read live from your own calendars each time they are shown and are never copied into Kalend's storage or uploaded anywhere.
Yes. When you create an event from quick add, Kalend uses the system event editor, which saves to your calendar without needing any permission from you.
A cushion. With one grace day (the default) you can miss a single required day without losing your streak — the next miss ends it. You can set it between 0 and 3 when editing a habit. It exists because research on habit formation found that missing one opportunity does not meaningfully set you back, so an app that punishes it is working against you.
Because that is what it is measuring. A habit done a set number of times per week is judged per week, so its streak counts consecutive successful weeks. A daily habit counts days.
The "21 days" figure is a myth with no supporting evidence. Lally and colleagues (2010) actually measured how long it takes a behaviour to become automatic and found a median of 66 days, ranging from 18 to 254 depending on the person and the habit. Kalend shows progress toward 66.
Yes. Open the habit and tap the day on the heatmap. Streaks are recalculated from your completion history, so correcting the past corrects the streak.
iOS allows an app a maximum of 64 pending notifications at once — a hard system limit with no way around it. Kalend keeps a rolling window of the soonest reminders and refreshes it every time you open the app, so if you set a very large number of far-future reminders, the distant ones are scheduled later rather than immediately. Opening the app periodically keeps the window topped up.
Settings → Notifications → Kalend → Allow Notifications.
Settings → your name → Subscriptions → Kalend → Cancel. Deleting the app does not cancel a subscription.
Open the paywall and tap Restore Purchases, making sure you are signed in with the Apple Account you bought it on. If that does not work, email us with the date of purchase.
All purchases go through Apple, so refunds are handled by Apple at reportaproblem.apple.com. We are not able to issue them directly.
Delete the app from your device, then remove its iCloud data in Settings → your name → iCloud → Manage Account Storage → Kalend. That erases everything the app has created. Because we hold no copy, nothing remains anywhere else.
