What’s actually slowing this PC down?

To keep message text off a locked iPhone’s screen, set notification previews to When Unlocked or Never. You can also control where Messages alerts appear, mute a particular conversation, screen messages from unknown senders, or delete a thread when you intend to remove it. These options protect against casual viewing and notification exposure; none hides a conversation that remains in Messages from someone who can use your unlocked iPhone.
Choose the right kind of privacy control
“Hide” can mean hiding message text in a notification, silencing an alert, filtering messages from unfamiliar senders, or removing a conversation. Those actions have different effects. In particular, muting and filtering do not conceal an existing known conversation.
| Control | What it changes | Scope | Do messages still arrive? |
|---|---|---|---|
| Show Previews | Whether notification text is visible | Messages notifications | Yes |
| Notification locations | Where Messages alerts appear | Messages notifications | Yes |
| Hide Alerts | Alerts for a conversation | One conversation | Yes |
| Allow Notifications off | All Messages alerts | Messages app | Yes |
| Screen Unknown Senders | Separates qualifying unknown senders into a filter | Unknown senders only | Yes |
| Delete conversation | Removes messages from your Messages history, subject to recovery and sync behavior | Selected conversation or messages | Not applicable |
1. Hide message previews on the Lock Screen
A preview can reveal the actual words in an incoming message. To keep the text hidden while the iPhone is locked, open Settings > Notifications > Show Previews and choose When Unlocked. The notification text appears after you authenticate. Choose Never if you do not want previews shown in notifications. Apple lists Always, When Unlocked, and Never; exact menu presentation can vary by iOS version. See Apple’s notification settings guide and Lock Screen feature guide.
2. Choose where Messages alerts appear
To keep Messages alerts off the Lock Screen, open Settings > Notifications > Messages and adjust the alert locations, such as Lock Screen, Notification Center, and Banners. Turning off a location reduces exposure there; it does not remove a conversation or hide it from someone who opens Messages.
3. Mute one conversation with Hide Alerts
To silence notifications from a particular thread without stopping delivery, open Messages and either swipe left on the conversation or open it and use its contact or conversation controls to turn on Hide Alerts. The exact control placement can vary by iOS version. New messages continue to arrive in the thread, but you are not notified about its activity. Apple notes that the sender may see that notifications are silenced. Its Messages notification guide distinguishes muting alerts from stopping message delivery.

4. Turn off all Messages notifications
If you want no Messages alerts at all, go to Settings > Notifications > Messages and turn off Allow Notifications. Messages still arrive, and you can open the app to read them. This affects every Messages conversation rather than just one thread. Apple describes the effect as stopping notifications while continuing to receive messages in its notification instructions.
5. Screen messages from unknown senders
On iOS 26, unknown-sender screening places qualifying messages in a separate filter; it is not a way to hide a conversation with someone you know. Apple says Screen Unknown Senders is off by default in iOS 26. To enable it, use either Messages > Filters > Manage Filtering or Settings > Apps > Messages > Unknown Senders. Consult Apple’s unknown-sender instructions for iOS 26.

6. Delete a conversation only if you intend to remove it
Deleting is different from hiding a thread: it removes messages from your own Messages history, but they may remain recoverable. Apple says deleted messages stay in Recently Deleted for up to 30 days, where they can be recovered or permanently removed. With Messages in iCloud on, deletion syncs across your participating Apple devices; it does not delete the recipient’s copy. See Apple’s guides to deleting messages and attachments and recovering deleted messages.

Blocking and reporting are separate tools
Blocking prevents messages from a specific person or number from being delivered, so it is useful when you want to stop contact—not to hide an existing thread. Blocking may also affect communication through other Apple apps. Reporting spam does not by itself stop further messages; Apple advises blocking the sender to stop receiving them. See Apple’s instructions for reporting spam and blocking senders.
