Introduction
This Privacy Policy explains how Last Defense: Phòng Tuyến Cuối ("the Game", "we", "our", or "us") handles information when you install, open, and play the Game. The Game is developed and published by BIEXCE Technology Investment & Solutions Company Limited.
We designed Last Defense: Phòng Tuyến Cuối as a single-player offline tower defense game. The current version is intended to run without user accounts, online profiles, advertising networks, analytics SDKs, or social login.
Information We Do Not Collect
Last Defense: Phòng Tuyến Cuối does not request or collect the following categories of personal information:
- Name, email address, phone number, home address, or identity documents.
- Precise location, contacts, calendar data, camera data, microphone data, or photo library data.
- Account credentials, social media profile information, or payment card information.
- Advertising identifiers used for targeted advertising in the current version.
Local Gameplay Data
The Game saves limited gameplay information locally on your device so it can work as expected. This may include:
- Current wave progress and the highest wave reached.
- Gold balance, towers built (positions and upgrade levels), and skill cooldown state.
- Collection unlock states — which zombies you have encountered.
- Basic settings such as audio mute state.
- Other non-personal progress values required for normal gameplay.
This local gameplay data is stored on your device using standard Android storage. We do not use this data to identify you, contact you, track you across apps, or build a personal profile.
Permissions
Last Defense: Phòng Tuyến Cuối is designed to operate without requesting sensitive device permissions such as camera, microphone, contacts, precise location, or photo library access.
If a future version requires a permission for a new feature (for example, vibration for haptic feedback), this Privacy Policy will be updated to explain why that permission is needed.
Ads, Analytics, and Tracking
The current version of Last Defense: Phòng Tuyến Cuối does not include third-party advertising, third-party analytics, behavioral tracking, or targeted advertising.
We do not sell personal information and do not share personal information with advertisers or any third party.
Game Assets and Audio
The Game uses local visual and audio assets bundled inside the build, including background music, button sound effects, gameplay sound effects, tower and zombie sprites, UI artwork, menus, popups, and the app icon. These assets are used solely to provide the gameplay experience.
Some audio assets (such as background music or sound effects) may be sourced from royalty-free or licensed audio libraries (for example, Pixabay). These audio files are bundled locally with the Game build and are not used to collect, transmit, or analyze player information.
Children's Privacy
Last Defense: Phòng Tuyến Cuối is a general audience game with cartoon visuals and does not knowingly collect personal information from children. Because the Game does not require registration or personal details, it is designed to avoid collecting personal data from children entirely.
If you believe that a child has provided personal information to us, please contact us using the email below so we can review and address the issue.
Data Retention and Deletion
Local gameplay data remains on your device until you clear the Game's app data, reset your device, or uninstall the Game. Uninstalling the Game normally removes locally stored gameplay data from your device.
You can clear save data at any time from the in-game menu (Quit to Menu → New Game), or from Android's Settings → Apps → Last Defense → Storage → Clear Data.
Security
Since Last Defense: Phòng Tuyến Cuối does not require accounts or transmit personal gameplay profiles in the current version, the privacy risk is inherently limited. All data stays on your device.
We still strive to keep the Game simple, secure, and respectful of player privacy.
Changes to This Policy
We may update this Privacy Policy if Last Defense: Phòng Tuyến Cuối adds new features, online services, advertising, analytics, cloud saves, leaderboards, account systems, or other data-related functionality.
When changes are made, the "Last updated" date at the bottom of this page will be revised accordingly.
