Your kid uses your phone and sees your reminders

When your kid uses your phone, your reminders are one tap away in the app, in a widget on the Home Screen, and in every alert that arrives while they're holding it. For a borrowed phone the quick fix is Guided Access, which keeps them inside the one app you hand them; the lasting fix is a locked Reminders app, previews that wait for your face, and, when they're old enough for a device of their own, an Apple Account of their own.

Most of it is harmless. Some isn't theirs to read: a gift for them, a doctor's appointment, a note to talk to their teacher.

Where it shows up

• The Reminders app itself, and Recently Deleted inside it
• A Reminders widget on the Home or Lock Screen, showing whatever list you pointed it at
• Alerts on the Lock Screen and as banners over the game they're playing
• Spotlight, which Apple's search guide says works from the Home Screen and the Lock Screen
• Siri, and in iOS 18 and later the Calendar app, which lists scheduled reminders
• Your Apple Watch, if it's on the table

What to do

1. Guided Access when you hand the phone over. Set it up once: Settings, Accessibility, Guided Access, turn it on and set a passcode (Apple's page). Then open the app they'll use, triple-click the side button and tap Start; the phone stays in that app, with a time limit if you set one. To end it, triple-click again (double-click on iOS 18 and earlier), enter the passcode or use Face ID, and tap End. Apple warns that Crash Detection and Emergency Services aren't available during a session
2. Lock the Reminders app with Face ID. Touch and hold the Reminders icon and tap Require Face ID (Apple's lock an app page). Apple says information inside a locked app won't appear in notification previews, search or Siri suggestions, and the app locks again when you quit it. iOS 18 or later, and per phone
3. Hide the words in alerts. Settings, Notifications, Reminders, Show Previews: choose When Unlocked, or Never if your kid knows your passcode (Apple's notification settings); under Alerts on the same screen you can keep Reminders off the Lock Screen altogether
4. Trim the Lock Screen, the widget and search. In Settings, Face ID & Passcode, turn off Widgets under Allow Access When Locked; Apple's Lock Screen page says that stops someone holding your iPhone from seeing personal information in them. Point any Reminders widget at a list you'd be happy for them to read. In Settings, Search, tap Reminders and turn off Show App in Search (Apple's search guide; before iOS 18 it's under Siri & Search)
5. Lock your Screen Time settings. Settings, Screen Time, Manage Screen Time, Lock Screen Time Settings, then a four-digit passcode and a recovery option (Apple's page); no Screen Time setting changes without it after that. Content & Privacy Restrictions can also hide some built-in apps and features (Allowed Apps & Features on iOS 18, Other Features on iOS 27, per Apple's Screen Time guide), but Apple's examples are AirDrop and Camera; Reminders isn't named, so check the list on your phone
6. When they get their own device, give them their own account. A parent creates the account for a child under 13 (the age varies by country) from Settings, Family, Add Member, Create Child Account (Apple's Child Account page), and Apple's Screen Time page says it's important that your child has their own Apple Account and isn't sharing one with anyone else. You manage their controls from your own phone through Family Sharing; in iOS 27 the new parental controls need every device in the family group on iOS 27
7. Mind the Watch. In the Apple Watch app on your iPhone, tap My Watch, Notifications, Reminders, Custom, and choose Send to Notification Center or Notifications Off; on the watch, Settings, Notifications, turn on Tap to Show Full Notification, so the full alert waits for a tap (Apple's watch settings). A watch set up for your kid through Apple Watch For Your Kids runs on their own Apple Account (Apple's setup page), and Apple says mirrored settings don't apply to it

The catches

• Guided Access only lasts the session. It's for the phone you hand over, not the one left on the counter
• A lock is only as good as your passcode. A locked app opens with Face ID, Touch ID or your passcode, so a kid who knows the passcode can open it; the same problem with a grown-up is its own page
• When Unlocked means when anyone unlocks it. Hand over an unlocked phone and previews show as usual; Never is the setting that holds, and the alert still arrives without the words
• The Watch follows the phone. It mirrors the iPhone's notification settings by default, Apple says; a watch for a family member needs a cellular model and a Family Sharing group
• Their own account is a project, not a toggle. Worth it, not for tonight. If the shared thing is an iPad, see your reminders show up on the family iPad

Where Notif fits

Notif is the reminders app I make, and every note in it is a real reminder in Apple Reminders, on Notif's own list, so a kid on your phone could read it like any other. For the notes that aren't theirs to see, the gift or the appointment, there is a private switch: mark the note private, and the box below says exactly what that does. Only the notes you mark private are private; the rest can be sent, one at a time, to Notif's server and an AI provider to write their Insight. Notif is free on the App Store: get Notif.

Questions

What's the fastest way to hand my kid my phone without them seeing my reminders?

Guided Access. Open the app they'll use, triple-click the side button and tap Start; the phone stays in that app until you end the session with your Guided Access passcode or Face ID

Can I lock the Reminders app so my kid can't open it?

Yes, on iOS 18 and later. Touch and hold the Reminders icon and tap Require Face ID. Apple says information inside a locked app won't appear in notification previews, search or Siri suggestions, and the app opens with Face ID, Touch ID or your passcode

How do I stop reminder alerts showing their words while my kid has the phone?

Go to Settings, Notifications, Reminders, Show Previews, and choose Never. When Unlocked shows the words once the phone is unlocked, including when you unlocked it and handed it over

Does my child need their own Apple Account?

For a device of their own, yes. Apple says a child under 13 needs an account a parent creates through Family Sharing, and that it's important they aren't sharing an account with anyone else. Their reminders stay in their account and yours in yours

Does a child's Apple Watch show my reminders?

Not when it's set up through Apple Watch For Your Kids, which runs on the child's own Apple Account. Your own watch mirrors your iPhone's notification settings by default, so whatever you allow on the phone can reach your wrist
