Lock Screen Privacy: Hide Sensitive Alerts Fast
Your lock screen shouts every text and code to anyone nearby. Lock screen privacy fixes that in minutes — hide the sensitive bits, keep the ping.
Your Lock Screen Is a Billboard — Make It a Whisper
By default, many phones show the full text of messages, emails, and one-time codes right on the lock screen. Anyone at the table, desk, or counter can read them without ever unlocking your phone.
Lock screen privacy changes the preview, not the alert. You still hear the ping and see which app called — the private words wait until you unlock. It pairs well with an app permissions check, because both shrink what strangers can see.
On iPhone: Show Previews Only When Unlocked
- Open Settings, then Notifications, then Show Previews.
- Choose When Unlocked — alerts show the app name, not the message text, while locked.
- For extra-sensitive apps, open that app in Notifications and turn off Lock Screen or set its preview to Never.
- Check Messages and Mail first — they carry codes, bills, and private chats.
Face ID makes this painless: glance at the phone, it unlocks, and the full preview appears for your eyes only.
On Android: Hide Sensitive Content
- Open Settings, then Notifications, then Lock screen notifications. Menu names vary a little by brand.
- Choose Hide sensitive content, or Show conversations, default and silent on Samsung phones.
- Open individual apps in the same list to silence or hide the nosiest ones completely.
- Test it: lock the phone, send yourself a text, and confirm only the app name shows.
| Setting | iPhone | Android |
|---|---|---|
| Main switch | Show Previews: When Unlocked | Hide sensitive content |
| Per-app control | Yes, in Notifications per app | Yes, in Notifications per app |
| What still shows | App name and icon | App name and icon |
| Missed alerts | Recover in Notification Centre | Recover with Notification History |
Missed something while it was hidden? Our notification history trick finds it fast, and Focus Mode quiets whole hours at once.
Go One Step Further: Shoulders and Codes
- Protect the codes. Hidden previews keep one-time codes off the billboard — a strong partner to our passkey guide.
- Stop shoulder surfing. A JETech Privacy Screen Protector for iPhone or a Belkin ScreenForce Privacy Screen Protector darkens side views so seatmates see nothing.
- Lock shared moments too. When you hand the phone over, app pinning keeps guests inside one app.

- iPhone: Show Previews set to When Unlocked. Android: Hide sensitive content.
- Tighten Messages, Mail, and banking apps first, then test with a locked self-text.

What is the one app you would never want popping up in full on your lock screen?
