Effective Date: 18 June, 2026
This Privacy Policy explains how Odyssey Apps and Games Inc. collects, uses, and protects information when you use our app Calculator Lock: App Locker.
By using this app, you agree to this Privacy Policy.
We try to collect only the information needed to provide and improve the app.
The app may process the following types of information:
Photos, videos, audio files, documents, and notes selected by the user
App lock settings selected by the user
Device and app usage information through third-party services
Crash and performance information
Advertising-related information if ads are shown in the app
Your private vault files and notes are mainly stored on your device or app storage. We do not ask users to upload their private vault content to our own server.
We use information to:
Provide the vault and file hiding features
Let users lock and unlock private content
Let users lock selected apps
Improve app performance and stability
Fix bugs and crashes
Show ads, if available in the app
Understand general app usage through analytics
We do not sell your personal files, private notes, photos, videos, audio files, or documents.
Our app may request the following permissions to provide its features:
We use biometric permission to allow users to unlock the vault using fingerprint, face unlock, or other supported biometric methods.
We use the camera permission for the Intruder Alert feature. If this feature is enabled, the app may capture a front-camera photo after repeated failed unlock attempts.
We use photo and video access permissions to allow users to import, view, hide, lock, and manage photos and videos inside the vault.
We use storage access permissions to read, move, hide, or delete selected photos, videos, audio files, and documents from the device storage, depending on the user’s action and Android version.
We may request All Files Access permission to manage vault files and remove original files from device storage after they are hidden inside the vault.
We use usage access permission to detect which app is currently opened. This is needed so the App Lock feature can show a lock screen for protected apps.
We use this permission to show the app lock screen over selected protected apps.
We use foreground service permission to keep the App Lock feature running reliably in the background.
We use notification permission to show service notifications required for app lock and background protection features.
We use boot completed permission to restart protection features after the device is restarted.
We access the list of installed launcher apps so users can choose which apps they want to lock. We do not use this access to collect unnecessary app data.
We may use Device Administrator access for the Uninstall Protection feature. This feature helps protect the user’s private vault data by preventing unauthorized people from uninstalling the app without the correct app password.
When this feature is enabled, the app may require the correct password before uninstall protection can be turned off. After the correct password is entered, the user can disable uninstall protection and uninstall the app.
This permission is used only to protect the user’s private content from unauthorized access or deletion. We do not use Device Administrator access to control the device for any unrelated purpose.
Our app may use third-party services that may collect, process, or share information according to their own privacy policies.
These services may include:
Google Play Services
https://policies.google.com/privacy
Google AdMob
https://support.google.com/admob/answer/6128543
Firebase Analytics
https://firebase.google.com/support/privacy
Firebase Crashlytics
https://firebase.google.com/support/privacy
These services may collect information such as device information, app usage data, advertising identifiers, crash logs, and performance data. This information helps us improve the app, fix issues, and show ads.
Our app may show ads using Google AdMob. AdMob may use device information and advertising identifiers to show ads and measure ad performance.
Users may be able to manage ad personalization from their device settings or Google account settings.
We may use Firebase Analytics to understand how users interact with the app. This helps us improve features and user experience.
We may use Firebase Crashlytics to collect crash reports and performance information. This helps us find and fix technical problems.
Files, notes, and private content added to the vault are stored on the user’s device. Users are responsible for keeping backups of important files.
If the app is deleted, device storage is cleared, or data is removed by the user, vault content may be lost.
We do not sell users’ private vault content.
We may share limited information with third-party services listed in this Privacy Policy for app functionality, analytics, crash reporting, and advertising.
We may also disclose information if required by law or to protect our rights, users, or services.
We care about protecting user privacy. We use reasonable measures to protect information handled by the app.
However, no app, storage system, or internet-based service can be guaranteed to be 100% secure.
Users can:
Choose which files to hide or protect
Choose which apps to lock
Enable or disable optional features such as Intruder Alert
Enable or disable Uninstall Protection
Allow or deny permissions from Android settings
Clear app data or uninstall the app after disabling uninstall protection, if enabled
Some features may not work properly if required permissions are denied.
Our app is not intended for children under the age required by applicable law. We do not knowingly collect personal information from children.
If you believe a child has provided personal information through the app, please contact us so we can take appropriate action.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
Users are encouraged to review this Privacy Policy regularly.
