Modern smartphones carry our most sensitive personal and financial data—from banking applications and cryptocurrency wallets to private messaging conversations and health records. Handing your phone to a friend or colleague to share photos or show a navigation map can introduce anxiety about private notifications or accidental access to confidential information. To address this challenge at the operating system level, Google introduced Private Space in Android 15. Private Space creates a sandboxed, isolated profile on your device that completely conceals selected apps, data, and notifications behind a dedicated biometric authentication layer.
How Private Space Works in Android 15
Unlike third-party app lockers that merely place a pin prompt over an existing application, Private Space operates as a segregated Android user profile:
- Sandboxed Profile Isolation: Apps running inside Private Space operate within an independent security boundary. They have separate application data, independent storage volumes, and isolated cache directories.
- Separate Google Account Support: You can link a separate, dedicated Google Account to Private Space. This prevents your private browsing search history, Google Photos backups, and Play Store downloads from syncing with your primary personal account.
- Suppressed Notifications: When Private Space is locked, notifications, incoming alerts, background downloads, and calendar reminders from hidden apps are completely suppressed from the lock screen and notification shade.
- Hidden App Drawer Presence: You can configure Android 15 to make the Private Space container entirely invisible in your app drawer until you type a specific access keyword into the search bar.
Step-by-Step: Setting Up Private Space on Android 15
To initialize Private Space on a compatible device running Android 15 (such as Google Pixel devices):
- Open the Settings app on your Android device.
- Scroll down and select Security & privacy.
- Under the Privacy subsection, tap Private Space.
- Tap Set up on the onboarding splash screen.
- Authenticate using your current device screen lock (fingerprint, pattern, or PIN).
- Choose whether to sign in with a dedicated Google Account for Private Space (recommended for total account isolation) or tap Skip to proceed with your current configuration.
- Set a distinct lock method: choose Choose new lock to set a unique PIN, pattern, or password different from your primary device lock, and enrol fingerprint unlock.
- Tap Done to finalise the setup.
Installing and Moving Apps into Private Space
Once Private Space is established, you can populate it with sensitive applications:
- Swipe up from the bottom of your home screen to open the App Drawer.
- Scroll to the very bottom. You will see a container labelled Private with a lock icon.
- Tap the container and verify your identity using fingerprint or your Private Space PIN.
- Tap Install apps inside the container.
- Google Play Store opens within the Private Space sandbox. Browse or search for applications (such as mobile banking, password managers, or private messaging platforms) and tap Install.
Hiding the Private Space Container from the App Drawer
For maximum privacy, you can prevent the “Private” section from displaying in your app drawer altogether:
- Go to Settings > Security & privacy > Private Space.
- Tap the gear icon next to Hide Private Space when locked and toggle it On.
- When toggled on, the Private container disappears entirely from the bottom of your app drawer when locked.
- To access your hidden apps, open your app drawer search bar, type your secret keyword (or
Private Space), and press Enter to reveal the authentication prompt.
Configuring Auto-Lock Rules for Private Space
To avoid leaving private apps accessible when stepping away from your phone:
- Navigate to Settings > Security & privacy > Private Space > Lock Private Space automatically.
- Select your preferred auto-lock trigger:
- Every time device locks: Automatically locks the container whenever your phone screen turns off.
- 5 minutes after screen timeout: Provides a brief grace period if switching between apps.
- On device restart: Remains unlocked until a reboot (least secure).

| Notification Suppression | Complete (zero leaks when locked) | Complete | Partial (previews often leak) |
| Stealth Visibility Mode | Yes (hides from search & drawer) | Yes (hide icon toggle) | Rarely |
| Platform Availability | All Android 15+ devices (AOSP) | Samsung Galaxy devices only | Any Android version |
| Separate Google Account | Yes | Yes | No |
Troubleshooting Common Private Space Issues
If you encounter unexpected behaviour with Private Space:
- Missing Notifications: If you are not receiving urgent messages from apps inside Private Space, remember that notifications are paused while locked by design. Unlock Private Space to allow applications to perform background synchronisation.
- File Transfer Between Spaces: To move a photo or document between your main profile and Private Space, use the system Share sheet and choose the Switch to Private / Personal tab.
- Deleting Private Space: If you decide to remove the profile, navigate to Settings > Security & privacy > Private Space > Delete Private Space. Note that this permanently erases all applications and local data stored inside the sandbox.
Frequently Asked Questions
Can applications in Private Space access my main photos or contacts?
No. By default, applications inside Private Space cannot access photos, media, contacts, or calendar entries stored in your personal profile unless you explicitly grant permissions or share them across profiles.
What happens to Private Space if I connect my phone to a PC via USB?
When your device is connected to a computer, the MTP file transfer protocol exposes only your primary user storage. Private Space storage volumes remain encrypted and unmounted until unlocked on the device.
Does installing duplicate apps in Private Space use additional storage?
Yes. Because Private Space maintains independent application binaries and cache data, apps installed in both your personal space and Private Space consume separate storage allocations.
