Last Updated: July 23, 2026
Thank you for using SMB2CNC (hereinafter referred to as "the Application"). This Application is developed by Mobilednc. We attach great importance to your privacy and industrial data security. This Privacy Policy is intended to explain how we collect, use, protect, and process the information generated when you use this Application.
Please read this Privacy Policy carefully before using the Application. By installing or using the Application, you agree to the contents of this policy.
1. Information We Collect and Use
The primary function of this Application is to assist you in transferring files (such as G-code files) between your Android device, SMB network folders, and CNC machine tools. To provide these services, we may need to obtain the following permissions or data:
1.1 File and Storage Access (Local Storage)
The Application requires access to your local storage space to read, write, modify, or delete CNC files.
Data Destination: These files are kept solely locally on your device. We will NEVER upload your CNC files or any personal files to our servers or share them with any third parties.
1.2 Network and SMB Folder Access (Network & SMB Access)
The Application features the ability to connect to the local area network or remote SMB folders you specify.
Data Destination: The SMB server address, account, password, and other credential information you enter will only be encrypted and stored locally on your device for establishing connections. We do not collect or transmit this login information back to ourselves. The files you transfer over the network exist only between your device and the SMB server you designate.
1.3 USB Device Access (USB Serial Access)
The Application requires USB permissions to establish physical communication with your CNC machine via an RS-232/USB adapter cable.
Data Destination: This permission is strictly used for two-way file transmission (TX/RX) and will not be used to collect machine data or transmit it to external networks.
1.4 In-App Purchase Information (In-App Purchases)
The Application offers paid unlock features (e.g., unlocking daily transmission limits, SMB write functions). This transaction process is entirely handled by the Google Play Store.
Data Destination: We receive your purchase status (e.g., whether you have Pro privileges) to unlock app features, but we do not collect, store, or process your credit card information or detailed billing data.
1.5 System Notifications (Notifications)
The Application will request permission to send notifications, which is solely used to display the current transmission status and completion notices to you while file transfers are running in the background (e.g., receiving or sending progress).
2. Third-Party Services
The Application uses some third-party service libraries to maintain operations. These third-party services may have their own independent privacy policies:
Google Play Services / Google Play Billing Library: Used for processing in-app purchases and account authorization verification.
Analytics and Crash Reporting: We may use anonymous analytics tools to collect application crash logs and basic usage data to help us improve program stability. This data does not contain your personally identifiable information or the content of your CNC files.
3. Data Security Protection
We deeply understand the importance of industrial secrets (such as machining program codes) to you. Therefore, the core design of this Application is "localized processing":
We do not set up any cloud servers to relay your files.
All data flow occurs between your mobile phone, your local area network (SMB), and your CNC machine.
We take reasonable software protective measures to ensure the security of application settings and authorization data to prevent unauthorized access.
4. Children's Privacy
This Application is designed for industrial and professional manufacturing environments and is not developed for children under the age of 13 (or other statutory ages as prescribed in your jurisdiction). We do not knowingly collect personal information from children.
5. Modifications to the Privacy Policy
We reserve the right to modify this Privacy Policy at any time. In the event of material changes, we will inform you via in-app notifications or by updating the description on the Google Play Store page. We encourage you to review this policy periodically to stay informed about our latest privacy protection practices.
6. Contact Us
If you have any questions, suggestions, or concerns regarding this Privacy Policy or the data processing practices of this Application, please contact us through the following channels:

感謝您使用 SMB2CNC（以下簡稱「本應用程式」）。本應用程式由 Mobilednc 所開發。我們非常重視您的隱私權與工業資料安全。本隱私權政策旨在說明我們如何收集、使用、保護以及處理您在使用本應用程式時所產生的資訊。
在使用本應用程式之前，請仔細閱讀本隱私權政策。一旦您安裝或使用本應用程式，即表示您同意本政策的內容。
1. 我們收集與使用的資訊
本應用程式的主要功能是協助您在 Android 裝置、SMB 網路資料夾與 CNC 工具機之間傳輸檔案（如 G-code 檔案）。為了提供上述服務，我們可能需要取得以下權限或資料：
1.1 檔案與儲存空間存取 (Local Storage)
本應用程式需要存取您的本機儲存空間，以便讀取、寫入、修改或刪除 CNC 檔案。
資料去向： 這些檔案僅保存在您的裝置本地，我們絕不會將您的 CNC 檔案或任何個人檔案上傳至我們的伺服器或與任何第三方分享。
1.2 網路與 SMB 資料夾存取 (Network & SMB Access)
本應用程式具備連接您所指定的區域網路或遠端 SMB 資料夾的功能。
資料去向： 您輸入的 SMB 伺服器位址、帳號與密碼等憑證資訊，僅會加密儲存於您的裝置本地，用於建立連線。我們不會收集或回傳這些登入資訊。您透過網路傳輸的檔案，僅存在於您的裝置與您指定的 SMB 伺服器之間。
1.3 USB 設備存取 (USB Serial Access)
本應用程式需要 USB 權限，以透過 RS-232/USB 轉接線與您的 CNC 機台建立實體通訊。
資料去向： 該權限僅用於雙向檔案傳輸（TX/RX），不會用於收集機台資料或傳送至外部網路。
1.4 應用程式內購買資訊 (In-App Purchases)
本應用程式提供付費解鎖功能（如：解鎖每日傳輸限制、SMB 寫入功能等）。此交易流程完全由 Google Play 商店處理。
資料去向： 我們會接收您的購買狀態（例如：是否具備 Pro 權限）以解鎖應用程式功能，但我們不會收集、儲存或處理您的信用卡資訊或詳細帳單資料。
1.5 系統通知 (Notifications)
本應用程式會要求發送通知的權限，僅用於在背景執行檔案傳輸時（例如：接收或傳送進度），向您顯示目前的傳輸狀態與完成通知。
2. 第三方服務
本應用程式使用了部分第三方服務器庫來維持運作，這些第三方服務可能有其獨立的隱私權政策：
Google Play 服務 / Google Play 結帳服務：用於處理應用程式內購買及帳號授權驗證。
分析與崩潰回報：我們可能使用匿名的分析工具來收集應用程式崩潰日誌（Crash logs）與基本使用數據，以協助我們改善程式穩定性。這些數據不包含您的個人身分識別資訊或您的 CNC 檔案內容。
3. 資料安全保護
我們深知工業機密（如加工程式碼）對您的重要性。因此，本應用程式的設計核心為「本地化處理」：
我們不架設任何雲端伺服器來中繼您的檔案。
所有資料流動皆發生在您的手機、您的區域網路（SMB）以及您的 CNC 機台之間。
我們採取合理的軟體防護措施來確保應用程式設定與授權資料的安全，防止未經授權的存取。
4. 兒童隱私
本應用程式是為工業與專業製造環境所設計，並非針對未滿 13 歲（或您所在司法管轄區規定的其他法定年齡）的兒童所開發。我們不會故意收集兒童的個人資訊。
5. 隱私權政策之修改
我們保留隨時修改本隱私權政策的權利。重大變更時，我們將透過應用程式內通知或更新 Google Play 商店頁面的說明來告知您。我們建議您定期查看本政策，以確保了解最新的隱私權保護措施。
