PrintGo Privacy Policy
PrintGo (“the App”) is a mobile printing utility that sends documents and images from your device to printers on your local network or connected via Bluetooth. This policy explains what data the App accesses, how it is used, and what is not collected.
1. Developer & Contact
- Developer: PrintGo Team
- Contact email: 1172987229@qq.com
2. Data We Collect
We do not collect, store, transmit, sell, or share any personal data.
The App runs entirely on your device. It does not operate any backend server, does not use analytics SDKs, and does not use advertising SDKs.
3. On-Device Access to Device Functions
To perform its printing function, the App requests the following device permissions. All data accessed through these permissions stays on your device and is used only to build a print job that you explicitly submit to a printer you choose.
| Permission | Why it is needed | Leaves your device? |
|---|---|---|
CAMERA | Optional “scan document” feature that captures photos to print. | No. Images stay on the device until you send them to your chosen printer. |
BLUETOOTH_SCAN, BLUETOOTH_CONNECT | Discover and connect to ESC/POS thermal receipt printers over Bluetooth. | No. Used only to address the printer you pick. |
INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE, CHANGE_WIFI_MULTICAST_STATE | Discover printers on your local Wi-Fi network (mDNS/Bonjour) and send print jobs over IPP / LPD / RAW 9100. | No. Traffic is sent to printers on your LAN only. |
To let you print photos from your gallery, the App uses the Android system Photo Picker. The system shows its own picker UI and hands the App only the images you explicitly select — no gallery-wide media permission is requested or required.
The App does not access your contacts, calendar, microphone, precise location, SMS, call logs, or any identifier such as IMEI/MAC/advertising ID.
4. Network Traffic
The App communicates with printers on your local network. It does not send any data to servers operated by the developer or third parties. Because common printing protocols (RAW 9100, LPD, IPP) transmit plaintext by design, print traffic inside your LAN is not encrypted — this is a property of the protocols themselves and is outside the control of the App.
5. Children’s Privacy
The App is not directed to children under 13 and does not knowingly collect information from children.
6. Data Retention & Deletion
Because the App stores nothing on any server, there is nothing for us to delete. To remove locally cached print history, uninstall the App or clear its data from Android Settings.
7. Third-Party Services
The App does not integrate any third-party analytics, advertising, crash reporting, or tracking services.
8. Changes to This Policy
We may update this policy if the App’s functionality changes. Updates will be published at the same URL with a new “Last updated” date. Continued use of the App after an update constitutes acceptance of the revised policy.

PrintGo 隐私政策（中文）
PrintGo（“本应用”）是一款移动打印工具，可将设备上的文档和图片发送至同一局域网内或通过蓝牙连接的打印机。本政策说明本应用访问哪些数据、如何使用，以及不会收集哪些数据。
1. 开发者与联系方式
- 开发者：PrintGo Team
- 联系邮箱：1172987229@qq.com
2. 我们收集的数据
本应用不收集、不存储、不传输、不出售、不共享任何个人数据。
本应用完全在您的设备本地运行，不运营任何后端服务器，不使用任何数据分析 SDK，不使用任何广告 SDK。
3. 设备权限使用说明
为了完成打印功能，本应用需要请求以下设备权限。通过这些权限访问到的任何数据均仅保存在您的设备上，并且只用于生成您主动提交给所选打印机的打印作业。
| 权限 | 用途 | 是否离开设备 |
|---|---|---|
CAMERA | 可选的“扫描件”功能，用于拍照后打印。 | 否。图片仅保存在设备本地，除非您主动发送到所选打印机。 |
BLUETOOTH_SCAN、BLUETOOTH_CONNECT | 发现并连接 ESC/POS 蓝牙热敏打印机。 | 否。仅用于寻址您选择的打印机。 |
INTERNET、ACCESS_NETWORK_STATE、ACCESS_WIFI_STATE、CHANGE_WIFI_MULTICAST_STATE | 通过 mDNS/Bonjour 发现局域网内打印机，并通过 IPP / LPD / RAW 9100 协议投递打印作业。 | 否。流量仅发送至您本地网络内的打印机。 |
打印相册图片的能力通过 Android 系统自带的“Photo Picker”完成：由系统弹出选择界面，只将您显式选中的图片交给本应用；本应用不会申请、也无需任何相册 / 媒体权限。
本应用不会访问您的通讯录、日历、麦克风、精确位置、短信、通话记录，也不会访问 IMEI / MAC 地址 / 广告标识等任何设备标识符。
4. 网络流量
本应用仅与您本地网络中的打印机通信，不会向开发者或任何第三方的服务器发送数据。常见打印协议（RAW 9100、LPD、IPP）的规范本身使用明文传输，因此局域网内的打印流量未经加密——这是协议本身的特性，不在本应用控制范围之内。
5. 儿童隐私
本应用不面向 13 岁以下儿童，亦不会主动收集儿童信息。
6. 数据保留与删除
由于本应用不在任何服务器上存储任何数据，也就没有数据需要我们删除。如需清除本机的打印历史等本地缓存，请通过系统“设置”卸载本应用或清除其数据。
7. 第三方服务
本应用未集成任何第三方数据分析、广告、崩溃上报或用户追踪服务。
8. 政策变更
若本应用功能发生变化，我们可能会更新本政策。更新后的政策将发布于同一 URL，并更新“最后更新”日期。如您在政策更新后继续使用本应用，即视为接受更新后的政策。
9. 联系我们
