App Lock - Fingerprint & PIN

Privacy Policy

Effective date: November 6, 2026 · Last updated: November 6, 2026

This Privacy Policy explains how App Lock - Fingerprint & PIN (the “App”), published on Google Play by Atharv Apps World (“we”, “us”), handles information when you use the App on your Android device. The App’s package name is com.atharvapplock.lockapps.atharva.

You can open this policy at any time from Settings › Privacy Policy in the App. By using the App you agree to this policy. If you do not agree, please uninstall the App.

In short

• We have no user accounts and no servers of our own. Nothing you lock, hide or set up in the App is sent to us.

• Your PIN, pattern, locked-app list, unlock history, vault files, vault notes and intruder photos stay on your device. Vault photos and videos are encrypted.

• Fingerprint unlock is handled by Android. The App never receives your fingerprint.

• The App shows ads and uses Google services (AdMob and Firebase) that collect limited device and usage data, as described below.

• We do not sell your personal information.

1. Information that stays on your device

The following is created by you or by the App’s features and is stored only in the App’s private storage on your device. We cannot see it, and it is not uploaded anywhere.

• PIN and pattern. Saved in hashed form (never as plain text) in the App’s private storage, which is encrypted with an Android Keystore key on devices that support it.

• Locked apps and settings. The list of apps you choose to lock, your lock schedules, themes and other preferences.

• Private Vault. Photos and videos you move into the Vault are copied into the App’s private storage and encrypted (AES-256). The original copy is removed from your gallery. Vault notes are kept in the App’s private storage, encrypted on devices that support it. Items you delete from the Vault move to the Vault trash and stay there until you empty it.

• Intruder selfie (optional, off by default). If you turn it on, the App uses the front camera to take a photo after a set number of wrong unlock attempts. The photo, its time and the app that was being opened are saved in the App’s private storage so you can review them.

• Unlock history (on by default). Each PIN, pattern or knock-code entry on the lock screen, right or wrong, and each fingerprint unlock is saved with the name of the app being unlocked and the time. Only the latest 200 entries are kept, and only on your device.

• Custom backgrounds. Images you pick and photos you take with the camera for themes are copied into the App’s storage. They leave the App only if you choose to share them or set them as your phone wallpaper.

• After-call screen (optional, off by default). If you turn it on, the App detects when a phone call ends and shows a screen with the caller’s number and the call duration. The number of the most recent call stays in the App’s storage on your device until the next call replaces it. Actions such as call back, SMS, WhatsApp or add contact open the relevant app only when you tap them.

Backups: The App turns off Android cloud backup, so this data is not copied to Google Drive. If you uninstall the App or clear its data, everything above, including Vault files, is permanently deleted. Move any Vault files out of the Vault before uninstalling.

2. Information collected by third-party services

The App uses the following Google services. They may collect information automatically from your device and process it under their own privacy policies.

Google AdMob (advertising)

Shows ads in the App. AdMob may collect your device’s advertising ID, IP address, device and app information, and how you interact with ads. It uses this information to show, measure and improve ads, to prevent fraud, and to personalise ads.

In the European Economic Area, the United Kingdom and Switzerland, the App shows Google’s consent form (User Messaging Platform), and ads are personalised only if you consent. In these regions you can change or withdraw your choice at any time from Settings › Ad privacy options in the App. Elsewhere, ads may be personalised unless you opt out in your device’s ad settings (see section 7).

Google Analytics for Firebase

Helps us understand how the App is used so we can improve it. It records events such as app opens, sessions, screens and ad events (ad requested, loaded, failed, shown, tapped and closed, and the revenue an ad earned). The following details are attached:

• app version

• device model and Android version

• country and language from your device settings

• connection type (Wi-Fi or mobile data)

• an app-instance identifier

• your advertising ID, where available

Google may also estimate your approximate location (for example, city) from your IP address, and may learn how the App was installed (for example, from which store page or ad) through the Google Play Install Referrer and Android’s ad attribution features. We do not send the names of the apps you lock, your PIN or pattern, your unlock history, or anything from the Vault or intruder photos.

Firebase Crashlytics

When the App crashes, Crashlytics sends a crash report so we can fix the problem. The report contains:

• technical details of the error

• device model and Android version

• app state at the time of the crash, such as free memory and orientation

• a random installation identifier

Crashlytics also records each app session (its time, the installation identifier, device model, Android version and app version), even when nothing crashes, to measure how often the App runs without crashing.

Firebase Remote Config

Lets us change some App settings, such as which ad formats are shown, without releasing an update. To fetch these settings it sends a random installation identifier and your device’s country, language, time zone and Android version.

• How Google uses information from apps that use its services (https://policies.google.com/technologies/partner-sites)

• How Google uses information for advertising (https://policies.google.com/technologies/ads)

• Privacy and security in Firebase (https://firebase.google.com/support/privacy)

3. When you contact us

If you email us, for example with Send feedback or Request a feature in the App, we receive your email address and your message. The App adds your app version, device model and Android version to the email so we can understand the problem; you can remove them before sending. We use this information only to reply to you and to improve the App.

4. Permissions and why the App needs them

Each permission is used only for the purpose described. Sensitive permissions are requested only when you enable the feature that needs them, and you can turn them off in Android settings at any time. Some features will stop working if you do.

• Usage access: Tells the App which app is currently open, so it can show the lock screen in front of a locked app.

• Display over other apps: Shows the lock screen on top of locked apps, and shows the optional after-call and charging screens.

• See installed apps: Lists the apps on your phone so you can choose which ones to lock. The list is used only on your device.

• Camera: Used for the optional intruder selfie after wrong unlock attempts, and when you tap Take photo in the theme editor to take a photo for your lock-screen background. These photos stay on your device.

• Photos and videos / storage: Lets you choose photos and videos to move into the Vault and removes the original copy from your gallery.

• Phone state: Used only for the optional after-call screen, to know when a call has ended.

• Fingerprint / biometrics: Lets you unlock with your fingerprint. Android checks the fingerprint and only tells the App whether it matched.

• Notifications and foreground service: Keep app protection running and show a notification while it is active.

• Run at start-up, ignore battery optimisation: Restart protection after your phone reboots and stop Android from closing it in the background.

• Set wallpaper: Applies a theme as your wallpaper, only when you choose to.

• Vibrate: Gives haptic feedback when you enter a PIN or pattern.

• Internet, network state and advertising ID: Used by the Google services in section 2 for ads, analytics, crash reports and remote settings.

5. How information is shared

We do not sell, rent or trade your information. Information collected by Google AdMob is shared with Google, which uses it for advertising, ad measurement and fraud prevention under its own privacy policy. Firebase (Analytics, Crashlytics and Remote Config) processes data for us as a service provider. We may also disclose information if required by law or to protect the rights and safety of our users.

6. Data retention and deletion

• On-device data is kept until you delete it in the App, clear the App’s data, or uninstall the App. Vault items you delete stay in the Vault trash until you empty it. The unlock history and custom background images are removed only when you clear the App’s data or uninstall the App.

• Data held by Google services is kept for a limited time under Google’s retention policies and is then deleted or anonymised.

• Emails you send us are kept only as long as needed to answer you. Ask us and we will delete them.

• Because the App has no accounts and does not show its analytics or crash identifiers, we cannot find the data of a single user in Google’s services, so we cannot delete it on request. It expires automatically under Google’s retention settings. You can reset or delete your advertising ID at any time (see section 7), and you can contact us with any question (see section 11).

7. Your choices

• Keep optional features such as intruder selfie and the after-call screen turned off, or turn them off at any time in the App’s settings.

• In the EEA, the UK and Switzerland, change or withdraw your ad consent at any time from Settings › Ad privacy options.

• Turn off the unlock history in Magic › Unlock Attempts (it is on by default). This stops new entries; saved entries are removed when you clear the App’s data.

• Revoke any permission in Android Settings › Apps › App Lock › Permissions, or turn off the App’s usage access in Settings › Usage access.

• Reset or delete your advertising ID, or opt out of personalised ads, in your device settings (usually Settings › Privacy › Ads or Settings › Google › Ads).

• Uninstall the App to stop all collection by the App and delete all on-device data.

8. Security

We protect information on your device by encrypting Vault media and, on devices that support it, the App’s settings storage with keys kept in the Android Keystore. No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security. Keep your PIN private and your device updated.

9. Children’s privacy

The App is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided information through the App, contact us and we will help remove it.

10. Changes to this policy

We may update this Privacy Policy from time to time. Changes are posted on this page with a new “Last updated” date. Continuing to use the App after an update means you accept the revised policy.
