Your privacy is
our highest priority.

App Lock is built with privacy-first principles:

• NO data collection whatsoever
• NO analytics or tracking services
• NO advertisements or ad networks
• NO internet connection required
• NO cloud storage or syncing
• NO third-party integrations
• NO user accounts or registration
• NO cookies or tracking pixels
• NO behavioral profiling
• NO data sharing with anyone

Everything you do in App Lock stays on your device. Period.

We want to be crystal clear about what we DON'T collect:

• Personal Information: No name, email, phone number, or identifying information
• Usage Data: No tracking of which apps you lock or usage patterns
• Device Information: No device IDs, IP addresses, or hardware information
• Location Data: No location information whatsoever
• Photos/Videos: Your vault contents never leave your device
• Contacts: We don't access your contacts
• Messages: We don't read your SMS or messaging apps
• Browsing History: We don't track your web browsing
• Crash Reports: We don't collect crash reports or error logs
• Performance Metrics: We don't measure app performance or behavior

All data is stored locally on your device using Android's secure storage mechanisms with military-grade encryption:

• PIN/Pattern/Password: Stored in encrypted SharedPreferences on your device
• Security Question & Answer: Stored locally, never transmitted
• Locked Apps List: Stored in local app preferences
• Vault Photos/Videos: Encrypted using AES-256-GCM encryption and stored in the app's private directory. Files are encrypted with keys stored in Android KeyStore, making them unreadable even if someone gains access to your device storage.
• Intruder Photos: Stored locally in the app's private directory
• App Settings: All preferences stored in local SharedPreferences

Vault Encryption Details:

• Algorithm: AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode)
• Key Storage: Android KeyStore (hardware-backed when available)
• Each file is encrypted with a unique initialization vector (IV)
• Files are stored with .enc extension and are completely unreadable without the app
• Even with root access or file manager, encrypted files cannot be viewed
• Encryption keys never leave the secure hardware element

None of this data is uploaded to any server, shared with any third party, accessible to other apps, backed up to cloud services (unless you enable Android's backup feature), or transmitted over the internet.

Here's every permission we request and exactly why:

Since camera access is sensitive, here's exactly how we use it:

INTRUDER SELFIE FEATURE:

• ONLY activates after 3 wrong PIN attempts - camera is NEVER accessed before this
• Camera is NOT initialized when you open a locked app
• Camera is NOT running in the background
• Takes a single photo using front camera only after the 3rd wrong attempt
• Photo is saved to app's private directory on your device (not accessible to other apps)
• Photo is NEVER uploaded, transmitted, or shared with anyone
• You can view and delete intruder photos anytime in the Intruder Gallery
• Feature can be completely disabled in settings
• If camera permission is not granted, feature simply won't work (app locking still works)

WE NEVER:

• Access camera in the background or without explicit trigger
• Access camera when you open a locked app (only after 3 wrong attempts)
• Record video
• Upload photos or face data
• Share camera data with anyone
• Use camera for any purpose other than intruder detection
• Store photos anywhere except the app's private directory on your device

WHERE INTRUDER PHOTOS ARE STORED:

• Location: App's private directory (/data/data/com.aeroloomstudio.applock/files/intruders/)
• Access: Only accessible by App Lock, not by other apps or file managers
• Encryption: Stored in app's private storage (protected by Android's app sandboxing)
• Deletion: Automatically deleted when you uninstall the app
• Manual Deletion: You can delete individual photos or all photos from Intruder Gallery

App Lock offers optional Pro upgrades (Monthly, Yearly, and Lifetime plans) handled securely through Google Play Billing:

• Google Play processes all payments (we never see your payment information)
• Monthly ($2.99/month) and Yearly ($29.99/year) plans are subscriptions that automatically renew unless canceled
• Lifetime plan ($59.99 one-time payment) provides permanent Pro access
• You can manage or cancel your subscriptions at any time directly through the Google Play Store app
• We only receive a purchase confirmation status from Google Play to unlock Pro features
• Pro features work entirely offline and no additional data is collected for Pro users
• When you cancel a subscription, Pro features are automatically revoked at the end of the billing period

App Lock uses ZERO third-party services. No analytics, crash reporting, ad networks, cloud storage, social media integrations, or push notification services.

The ONLY external service involved is Google Play Store for Pro version purchases, which is handled entirely by Google's payment system. We never see your payment information.

App Lock does not collect any data from anyone, including children under 13. Since we don't collect any personal information, we comply with COPPA by default.

Since we don't collect any data about you, there's no data to request, delete, export, or correct. You have complete control over your data because it never leaves your device.

If we ever change this privacy policy, we will update the "Last Updated" date at the top of this page. Since we don't collect any data, any changes would likely be to clarify our existing practices or add information about new features.
