Events saved in your Google Calendar are shown in Smart Planner as well once you turn on "Link Google Calendar".
- Make sure your Google Account is registered on your device (you can check this in your device's "Settings" app → "Passwords, passkeys & accounts"; the item name may differ depending on your device)
- In Smart Planner's settings screen, turn on "Calendar Settings" → "Link Google Calendar"
- When the app asks for permission to access your calendar, choose "Allow"
- In the settings screen, tap "Calendar Settings" → "Visible Calendars" and check the Google calendars you want to see
Your Google Calendar events are now shown, and events you create in Smart Planner can be saved to Google Calendar as well (when creating an event, select a Google calendar as the "Calendar" to save it in).
※ Google Calendar events are fetched through the sync feature of the Google Account on your device. If they don't appear, please see "Google Calendar events aren't showing or syncing".
