Support

Fern Pro is billed by Apple. On iPhone, open the Settings app, tap your name, then Subscriptions › Fern, then Cancel subscription. On a Mac, open the App Store, click your name, then Account Settings › Subscriptions. Your plans stay; Pro features stop at the end of the period you’ve paid for.

Apple handles all refunds for Fern Pro: request one at reportaproblem.apple.com. We can’t issue refunds ourselves, but email hello@fernplan.app if something went wrong and we’ll help. Canceling stops the next renewal, and Pro keeps working until the end of the period you’ve paid for.

Go to Settings › Calendars and allow Fern to use your calendars. Fern shows the calendars already on your iPhone or Mac, including Google or Outlook accounts you’ve added in your device’s settings. Free shows one calendar; Fern Pro shows all of them. Your calendar events stay on your device (Fern Assistant only sees the ones it needs when you ask it something). You can turn access off at any time.

Check that notifications are on for Fern (iPhone: Settings › Notifications › Fern; Mac: System Settings › Notifications › Fern), and that Focus modes allow Fern. Reminders are scheduled on each device, so they work offline; after you change something on another device, open Fern once if a reminder hasn’t updated.

Settings › Account and data › Save a backup saves everything to a file you keep. Restore it with Restore from a backup.

Settings › Account and data › Delete my account and data. This permanently removes your account and everything in it from our servers. Deleting your account doesn’t cancel Fern Pro: cancel it separately in your Apple ID settings.

Make sure you’re signed in to the same account on both. Changes usually show on your other device within a minute when both are online; anything you change offline syncs when you’re back online.
