Killion Files Privacy Policy
Effective date: 2026-08-31 | Last updated: 2026-08-31
Killion Files (the "Application") is a local-first, privacy-first Android file manager. This privacy policy explains how we handle your data. Our core principle is simple: your files are processed on your own device and are never uploaded to our servers.
1. Operator Information
The Application is operated by:
- Operator: Unknown Company (this information will be updated once the company entity is registered)
- Contact: a1090442016@outlook.com
2. Collection and Use of Personal Information
1. Purpose of collection: solely to provide core features such as file browsing and management, archiving and encryption, the Private Vault, LAN / remote file access, the Phone Cloud FTP server, transfers and downloads, cleanup, and media compression.
2. Method of collection: we do not actively collect your personal information. The Application has no user registration or account creation; all data processing is performed locally on your device.
3. Scope of collection: the Application does not collect the following personal information:
- Identity information such as name, national ID number, or phone number
- Sensitive personal information such as location, contacts, photos, or call logs
- Device identifiers (IMEI, MAC address, Android ID, etc.)
- Behavioral data such as browsing or search history
Apart from content you voluntarily send us via feedback email, we do not receive any of your personal information.
3. Locally Stored Data
To provide core functionality, the Application stores the following information locally on your device:
- Files in the Private Vault: encrypted on import, with encrypted thumbnails; auto-locked when you leave, with keys and the file list wiped from memory.
- Remote server credentials: URLs, usernames, and passwords for FTP / SFTP / SMB / WebDAV, encrypted and stored on your device, used only to connect to servers you configure yourself.
- App preferences: such as theme, archive / encryption options, and playback progress.
None of this data leaves your device. Uninstalling the Application removes all of it.
4. Network and Server Data Handling
- When you connect the Application to remote servers you configure yourself (FTP / FTPS / SFTP / SMB / WebDAV), the Application sends requests to that server to list, upload, download, or stream files. All of this is initiated by you. We have no control over how your server processes your data — please refer to that server's privacy policy.
- The "Phone Cloud" feature starts a local FTP server on your device. Other devices on the same LAN can access directories you choose via the address you provide. Data flows only between your device and your LAN — it is never uploaded to any server we operate.
5. Permissions Used
To provide its features, the Application requests the following permissions. All permissions are used solely to implement core functionality and never to access personal data beyond that scope:
- All files access (MANAGE_EXTERNAL_STORAGE): required for local file operations such as browsing, archiving, encrypting, extracting, and cleaning — processed locally, never uploaded.
- Media management (MANAGE_MEDIA): querying media files and moving files to the trash.
- Install packages (REQUEST_INSTALL_PACKAGES): to install APK files you have downloaded.
- Query all packages (QUERY_ALL_PACKAGES): used by the APK extraction feature.
- Network access (INTERNET / network state / Wi-Fi state): to connect to remote servers you configure and to LAN devices.
- Local network access (ACCESS_LOCAL_NETWORK / Wi-Fi multicast): to scan, discover, and connect to LAN devices.
- Background download (WAKE_LOCK / foreground service / notifications): to prevent the screen from sleeping and to show download progress.
- Biometrics (USE_BIOMETRIC): optional, for fingerprint / face unlock of the Private Vault.
- Shizuku (moe.shizuku.manager.permission.API_V23): optional, to access storage paths protected by scoped storage on non-rooted devices.
6. Third-Party Services
- The Application integrates no advertising, analytics, or crash-reporting SDKs.
- Donations: when you donate via PayPal, USDT (TRC20), WeChat, or Alipay, the transaction is handled by the corresponding platform, which collects and processes the relevant information according to its own policy. We do not receive your payment credential information.
- Feedback and community channels (email, Telegram, QQ, GitHub Issues) are operated by their respective platforms — please refer to their policies.
7. Children's Privacy
The Application is not directed at children and we do not knowingly collect personal information from children. The Application is not intended for children under 13 (or under 16 in jurisdictions where the GDPR applies, or as otherwise required by local law). If you believe a child has provided us with personal information, please contact us via the email below and we will cooperate to delete the relevant information.
8. Retention of Information
Apart from feedback emails you voluntarily send and unless otherwise required by law, we do not retain your personal information on any server. Uninstalling the Application removes all local data.
9. Information Security
- The Private Vault uses AES-256 encryption; sensitive information such as login credentials is stored encrypted.
- We follow the data-minimization principle, processing only the minimum data needed for core functionality, locally.
- No external scripts are loaded and no dynamic code is executed.
- We never sell, rent, or otherwise share your personal information.
10. Your Rights
- View and delete locally stored data through app settings or device storage.
- Disconnect from remote servers at any time.
- Uninstall the Application to remove all local data.
- Contact us via the email below regarding this Policy or your data.
If you are located in the EU, the UK, or another jurisdiction where the GDPR applies, you also have rights of access, rectification, erasure, restriction of processing, data portability, and the right to withdraw consent. If you are located in California (CCPA/CPRA) or another jurisdiction granting similar rights, you have the right to know about and delete your personal information and to opt out of the "sale" of your personal information — we do not sell any personal information. To exercise any of these rights, please contact us via the email below.
11. Changes to This Policy
As the Application evolves, we may update this Policy. On material changes, we will update the date at the top of this page and, where possible, notify you through other means.
12. Contacting Us
