EazySend 隐私政策

生效日期：2026 年 5 月 9 日

概述

EazySend 是一款局域网/跨网络文件传输工具，旨在让设备之间快速、安全地传输文件。我们高度重视您的隐私。

核心原则：EazySend 应用本体不收集、不上传、不存储任何用户数据。所有文件传输均在您的本地网络中完成，或通过加密中继通道传输。官方网站使用匿名访问统计（详见下文）。

本政策适用范围

本隐私政策涵盖两个独立部分：

  • EazySend 应用本体 — Android / iOS / Windows / macOS / Linux 客户端
  • 官方网站 eazysend.app — 下载页 / 隐私政策页等

两者数据收集策略不同，请分别参阅以下条款。

应用本体收集的信息

我们不收集任何信息。具体而言：

  • 不收集个人身份信息（姓名、邮箱、电话等）
  • 不收集设备标识符或广告 ID
  • 不收集使用分析或崩溃报告
  • 不追踪用户行为
  • 应用内不包含任何第三方分析 SDK

网站访问的信息收集

eazysend.app 官方网站使用 Google Analytics 4 进行匿名访问统计，帮助我们了解用户分布、改进文档与下载页：

  • 页面访问量与停留时间
  • 访问来源（搜索引擎 / 直接访问 / 外部链接）
  • 设备类型（PC / 手机 / 平板）与浏览器
  • 访问地理位置（国家 / 城市级，不收集精确位置）

GA4 默认匿名化，不识别个人身份，不与应用使用数据关联。

退出方式：通过 Google Analytics Opt-out 附加组件 拒绝统计，或在浏览器设置中启用 Do-Not-Track。

权限使用说明

EazySend 需要以下权限才能正常工作：

  • 网络访问（INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE）— 用于局域网设备发现和文件传输
  • 多播（CHANGE_WIFI_MULTICAST_STATE）— 用于通过 mDNS 发现同一网络中的其他设备
  • 存储访问（READ/WRITE_EXTERNAL_STORAGE, MANAGE_EXTERNAL_STORAGE）— 用于读取要发送的文件，以及保存接收到的文件
  • 前台服务（FOREGROUND_SERVICE, FOREGROUND_SERVICE_DATA_SYNC）— 用于在应用切到后台时保持传输不中断
  • 通知（POST_NOTIFICATIONS）— 用于显示传输进度
  • 唤醒锁（WAKE_LOCK）— 防止传输过程中设备休眠

数据传输

所有文件传输均在您的本地网络中直接在设备之间进行。文件数据不经过任何外部服务器。使用中继模式进行跨网络传输时，所有数据均为端到端加密。

数据存储

接收到的文件保存在您设备的本地存储中（默认保存到 Downloads/eazysend 目录）。应用本身不维护任何数据库或日志文件。

第三方服务

应用本体：不集成任何第三方服务、广告 SDK 或分析工具。

官方网站：使用 Google Analytics 4（访问数据由 Google 处理，详见 Google 隐私政策）。

儿童隐私

EazySend 不面向 13 岁以下儿童，也不会有意收集儿童的任何信息。

隐私政策变更

如果我们更新本隐私政策，将在此页面发布新版本并更新生效日期。

EazySend Privacy Policy

Effective Date: May 9, 2026

Overview

EazySend is a LAN/cross-network file transfer tool designed for fast, secure file sharing between devices. We take your privacy seriously.

Core Principle: The EazySend application does not collect, upload, or store any user data. All file transfers happen within your local network or through encrypted relay channels. The official website uses anonymous traffic analytics (details below).

Scope of This Policy

This privacy policy covers two independent parts:

  • EazySend application — Android / iOS / Windows / macOS / Linux clients
  • Official website eazysend.app — download page, privacy policy page, etc.

Data collection policies differ between the two; please refer to the relevant sections below.

Information Collected by the Application

We do not collect any information. Specifically:

  • No personal identifiers (name, email, phone, etc.)
  • No device identifiers or advertising IDs
  • No usage analytics or crash reports
  • No user behavior tracking
  • The application contains no third-party analytics SDKs

Information Collected by the Website

The eazysend.app website uses Google Analytics 4 for anonymous traffic statistics, to help us understand user distribution and improve documentation and download pages:

  • Page views and time on page
  • Traffic source (search engine / direct / external links)
  • Device type (desktop / phone / tablet) and browser
  • Geographic location (country / city level, no precise location)

GA4 anonymizes data by default, does not identify individuals, and is not linked to application usage data.

Opt-out: Use the Google Analytics Opt-out Browser Add-on to decline tracking, or enable Do-Not-Track in your browser settings.

Permissions

EazySend requires the following permissions to function:

  • Network (INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE) — For LAN device discovery and file transfer
  • Multicast (CHANGE_WIFI_MULTICAST_STATE) — For discovering other devices via mDNS
  • Storage (READ/WRITE_EXTERNAL_STORAGE, MANAGE_EXTERNAL_STORAGE, READ_MEDIA_*) — For reading files to send and saving received files
  • Foreground Service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_DATA_SYNC) — To keep transfers running in background
  • Notifications (POST_NOTIFICATIONS) — To display transfer progress
  • Wake Lock (WAKE_LOCK) — To prevent device sleep during transfers

Data Transfer

All file transfers happen directly between devices on your local network (LAN). File data never passes through any external server. When using relay mode for cross-network transfers, all data is end-to-end encrypted.

Data Storage

Received files are saved to your device's local storage (default: Downloads/eazysend). The app does not maintain any database or log files.

Third-Party Services

Application: No third-party services, advertising SDKs, or analytics tools integrated.

Official website: Uses Google Analytics 4 (data processed by Google — see Google Privacy Policy).

Children's Privacy

EazySend is not directed at children under 13 and does not knowingly collect any information from children.

Changes to This Policy

If we update this privacy policy, we will post the new version on this page and update the effective date.
