Support

That's normal, not a bug. Shared calendars sync through iCloud, and Apple batches changes to save battery, so it usually takes 1–2 minutes to appear. You can check the last sync time at the top of the Shared Calendars screen, and reopening the app pulls changes sooner.

Make sure you are signed in with the Apple account used for the purchase, then tap "Restore Purchases" at the bottom of the Premium screen. If it still does not work, email us — including the Support ID at the bottom of the app settings helps us find your purchase quickly.

Amadoo stores your data on your device and in your own iCloud. Sign in with the same Apple account on your new device, install Amadoo, and your schedules, timetable, and memos restore automatically. Before switching, make sure iCloud is turned on in the Settings app.

No — not a cent. Cancel any time before the trial ends and nothing is charged, and Premium stays active until the last day of the trial even after you cancel. You can cancel in the Settings app → your name → Subscriptions.

Tap the people button at the top of the calendar screen to open Shared Calendars. Create one with "New shared calendar" and send the invite link via any messenger — the recipient taps the link to join. If the link does not open, they can paste it into "Join with a link" on the same screen.

Open the Settings app on your iPhone → your name → Subscriptions, select Amadoo, and tap "Cancel Subscription". Premium stays active until the end of the period you already paid for.
