AppLock Privacy Policy

In short

• AppLock has no accounts, no advertising, no analytics and no crash reporting.
• We do not collect, sell or share your personal information.
• Your PIN, your list of locked apps and any intruder photos stay on your phone.
• The only network use comes from Google Play, which handles the Pro purchase.

What AppLock stores on your phone

All of this stays in AppLock’s private storage on your device. It is not sent to us or to anyone else.

• Your PIN or pattern. Stored only as a salted, one-way hash (PBKDF2-SHA256). AppLock cannot read your PIN back.
• Your recovery code. Stored the same way, only as a hash.
• Your list of locked apps and your settings. For example, when apps lock again, how many failed attempts trigger a photo, your language, and whether you have agreed to the accessibility explanation.
• Pro status. A yes or no flag that records whether Google Play confirmed your purchase.
• Intruder photos (Pro). The photo, the time it was taken, and the name of the app that was being opened.
• A backup file, only if you create one. It holds your locked-apps list and preferences. It never holds your PIN, recovery code or photos. It is saved where you choose.

Permissions and why AppLock asks for them

• Accessibility Service. Used for one purpose: to notice which app has just opened, so AppLock can show its lock screen in front of the apps you chose. It listens only for the app on screen changing. It does not read the text, passwords, messages or other content on your screen, and it does not record or collect anything. You can turn it off at any time in Android settings, which stops the protection.
• Camera. Used only to take an intruder photo with the front camera after failed unlock attempts, and only if you have bought Pro and left the feature switched on. Photos are saved on your phone.
• Notification access (optional). If you turn on “Hide notifications from locked apps”, Android lets AppLock see notifications posted by those apps. AppLock checks only which app sent each one and what type it is, dismisses it, and shows a generic “New notification” instead. It does not read, store or send the contents.
• Posting notifications. Used to show that generic “New notification”.
• Biometrics. Fingerprint and face unlock use Android’s own biometric prompt. AppLock only learns whether it succeeded. It never receives your fingerprint or face data.
• Network and billing. Android’s billing libraries from Google, used for the Pro purchase, need network permission. AppLock’s own code never uploads your data.

What we collect

We collect nothing. AppLock does not send any personal information, usage data, device identifiers or photos to our servers. We do not run servers for the app.

Third parties

Google Play. If you buy Pro, the purchase is handled by Google Play and Google Play Billing. Google may process information such as your Google account, purchase history and device details under Google’s Privacy Policy. We do not receive your payment details.

We use no advertising networks, analytics services or crash-reporting services.

Intruder photos

• They are taken only when someone fails to unlock, and only if you have Pro and the feature is on.
• They are stored privately on your phone, and nobody can see them unless they get into AppLock, which asks for your PIN, pattern or fingerprint.
• You can view, share, save or delete each photo. You can also choose automatic deletion after 7, 30 or 90 days.
• A photo may show a person other than you. Please use this feature only on your own phone and handle any photos responsibly. If you share a photo, you are responsible for how it is used.

Keeping and deleting your data

• Delete a photo, or all photos, any time in the Intruders tab.
• Uninstalling AppLock removes everything it stored on your phone. You can also clear its storage in Android settings.
• A backup file you exported, or a photo you saved or shared, stays wherever you put it until you delete it.
• If you copy your recovery code, it goes to your phone’s clipboard, as with any copied text.

Security

Your PIN and recovery code are stored only as salted hashes. AppLock’s data is kept in app-private storage, is excluded from Android’s cloud backup and device-to-device transfer, and its own screens are blocked from screenshots and the recent-apps view. No security measure is perfect, and AppLock is an added layer on top of your phone’s own screen lock, not a replacement for it.

Children

AppLock is not directed at children under 13 (or under 16 where local law sets a higher age). We do not knowingly collect information from anyone, including children.

Your rights

Depending on where you live, such as the UK and EU under data protection law, or California under the CCPA, you may have rights to access, correct or delete personal information, or to object to its use. Because AppLock does not send your information to us, we hold none about you to access or delete. Everything the app stores is on your phone, under your control. For information that Google holds about your purchase, please contact Google. If you have any question about this policy, please contact us.

Changes to this policy

If we change how the app handles information, we will update this page and the date at the top. For significant changes, we will also say so in the app’s update notes.
