Privacy Policy
1. Basic Principles
发送猫默认通过局域网在你授权或配对的可信设备之间直接传输内容。公网连接默认关闭；只有在先通过局域网将电脑设为“我的设备”、自行配置有效的 HTTPS 公网地址或反向代理并主动开启后，受支持的内容、设备标识、在线状态和必要请求元数据才会通过互联网传输。发送猫不提供公网中转或云端存储；请求会经过你选择的域名、反向代理、CDN、隧道或网络服务，相关服务商可能处理公网 IP 和连接日志。电脑可能在本机队列暂存待发送文件直至完成、取消、失败或过期。实时麦克风仍仅通过局域网传输。我们不会出售你的个人信息或将传输内容用于广告画像。
SendCat transfers content directly between trusted devices over the local network by default. Public Connection is off by default and is used only after you add a computer to My Devices over the local network, configure a valid public HTTPS address or reverse proxy, and explicitly enable it. Supported content, device identifiers, online status, and request metadata then travel over the internet. SendCat provides no public relay or cloud storage; providers you choose may process public IP addresses and connection logs. The computer may temporarily stage outbound files in its local queue. Live microphone audio remains local-network only.
2. iOS/iPadOS Platform Notes
本政策适用于发送猫 iOS/iPadOS 版。会员购买、订阅、退款、交易验证和恢复购买通过 Apple App Store 与 StoreKit 处理。会员状态、商品标识、权益有效期、购买时间、随机设备 ID 和剪贴板发送次数保存在本机，用于本机权益展示、恢复和次数控制；发送猫不会把 Apple 交易或这些本机权益记录上传到自有会员服务器。Apple 按其规则处理购买与账户数据，我们无法取得你的支付卡号或 Apple ID 密码。
This policy applies to SendCat for iOS/iPadOS. Membership purchases, subscriptions, refunds, transaction verification, and restoration use the Apple App Store and StoreKit. Membership status, product identifier, entitlement validity, purchase time, random device ID, and clipboard-send count stay on the device for local display, restoration, and usage control. SendCat does not upload Apple transactions or these local entitlement records to its own membership server. Apple processes purchase and account data under its rules; we do not receive your payment-card number or Apple ID password.
3. Local Network, Clipboard, Screenshots, And Files
为发现和连接同一局域网内的设备，发送猫会处理设备名称、设备类型、随机设备 ID、设备 IP 地址（当前 Wi-Fi/热点分配的本地 IPv4 地址）、端口、在线状态、配对状态、设备关系和配对密钥摘要。在你同意本政策后，应用会通过系统网络接口，在应用进入前台及网络状态变化时按需读取该设备 IP 地址，用于判断局域网连接状态、发现和连接同一网络内的设备及展示传输状态；该地址仅在本机和当前局域网内处理，不上传至我们的服务器，不用于广告画像。剪贴板、截图、图片和文件仅在你主动使用相关功能或开启对应开关时处理，并在授权设备之间加密传输。我们不会读取或收集 IMEI、IMSI、SUPI、SUCI、设备 MAC 地址、通讯录、通话记录、日历、短信或本机电话号码；图片、音视频和文件仅在你主动选择、发送、接收、保存或开启同步功能时处理。
To discover and connect devices on the same local network, SendCat processes device name, device type, random device ID, device IP address (the local IPv4 address assigned by the current Wi-Fi or hotspot), port, online status, pairing status, device relationship, and pairing-key digest. After you consent to this policy, the app uses the system network interface to read the device IP address as needed when the app enters the foreground or the network changes. It is used to determine local-network connectivity, discover and connect devices on the same network, and display transfer status. The address is processed only on your device and within the current local network, is not uploaded to our servers, and is not used for advertising profiles. Clipboard content, screenshots, images, and files are processed only when you actively use related features or enable related switches, and are transferred between authorized devices with encryption. We do not read or collect IMEI, IMSI, SUPI, SUCI, device MAC address, contacts, call logs, calendar, SMS, or the phone number of this device. Images, audio, videos, and files are processed only when you actively select, send, receive, save, or enable sync for them.
同意本政策不会开启或预先申请麦克风权限。“把手机用作电脑麦克风”是 iOS/iPadOS VIP 功能。只有在当前 Apple App Store VIP 权益校验通过，且你对在线并位于“我的设备”中的 Mac 或 Windows 电脑主动点击“连接麦克风”后，发送猫才会申请麦克风权限并采集实时音频。音频使用每次连接独立派生的会话密钥进行 AES-GCM 加密，仅通过当前局域网发送，只在内存中处理，不保存、不上传，也不用于广告、训练或分析。电脑端不能远程开启手机麦克风。只有你在前台主动建立、通过认证且已经进入使用状态的连接，才可在返回桌面或锁定手机后继续，此时 iOS 会持续显示麦克风使用指示。来电等音频中断、输入路由变化、网络丢失、目标离线、强制退出、恢复失败或你主动停止时，连接结束；尚未连成或已经结束的连接绝不会在后台开始或恢复。
Agreeing to this policy does not enable or pre-request microphone access. SendCat requests access only after the App Store VIP entitlement is verified and you tap Connect Microphone for an online Mac or Windows computer in My Devices. Audio is AES-GCM encrypted with a per-session key, sent only over the current local network, processed in memory, and is not saved, uploaded, or used for advertising, training, or analytics. A computer cannot remotely enable the phone microphone. Only a connection explicitly started in the foreground, authenticated, and already live may continue after you go Home or lock the phone while iOS displays its microphone-use indicator. An audio interruption, input-route change, network loss, target going offline, force quit, recovery failure, or your stop action ends it. A pending or ended connection never starts or resumes in the background.
4. Feedback, Bugs, And Diagnostic Logs
只有当你进入客户端反馈入口并点击“发送”，或主动通过邮箱联系我们时，我们才会收到反馈。普通建议包含你填写的内容、设备型号、系统版本和客户端版本；BUG 反馈还会附带发送按钮前明确说明的最近错误码、运行状态、时间、连接状态、功能调用结果和必要诊断日志。连接诊断、配对失败和自动修复只在本机记录，不会静默上传。上述信息仅用于回复、复现、定位和修复本次问题。
We receive feedback only when you open the client feedback entry and tap Send, or contact us by email. A suggestion contains your text, device model, and system and client versions; a bug report also includes the recent diagnostic fields described before the Send button. Connection diagnosis, pairing failures, and automatic repairs stay local and are not silently uploaded. Submitted data is used only to respond to and repair the reported issue.
5. Information Types And Purposes
我们仅在实现明确功能、保障设备与会员权益安全、处理购买或恢复权益、排查故障、回复反馈、履行法定义务所必要的范围内处理信息。设备标识、设备名称、系统版本、客户端版本、连接状态、错误码和诊断日志用于设备发现、配对、连接、传输状态展示、异常定位和安全风控；会员、订单和权益信息用于开通、校验、恢复、退款或争议处理；你主动提交的联系方式、问题描述、截图和沟通记录用于客服回复、投诉处理和服务改进。
We process information only as necessary for clear functions, device and membership security, purchase or entitlement restoration, troubleshooting, feedback response, and legal compliance. Device identifiers, device name, system version, client version, connection status, error codes, and diagnostic logs are used for device discovery, pairing, connection, transfer status display, issue diagnosis, and security risk control. Membership, order, and entitlement information is used for activation, verification, restoration, refunds, or dispute handling. Contact details, issue descriptions, screenshots, and communication records you submit are used for support replies, complaint handling, and service improvement.
6. Clipboard, Screenshots, Images, Videos, And Files
发送猫不会在未触发功能时主动读取你的剪贴板、相册或文件。相关内容默认通过局域网处理；只有你自行配置并开启公网连接时，受支持的内容才会通过互联网直达指定电脑。除你选择的公网服务另有规则外，内容不上传至发送猫运营的服务器。公网传输的单个文件上限为 10 GiB。
SendCat does not proactively read your clipboard, albums, or files. The local network is used by default; supported content travels over the internet only when you configure and enable Public Connection yourself. Content is not uploaded to SendCat-operated servers. A single public-transfer file is limited to 10 GiB.
7. Permissions
首次运行时，发送猫先明示处理目的、方式和范围；你同意后才启动本地网络发现、接收监听、剪贴板监听和分享文件处理。应用按功能申请本地网络、麦克风、照片读取/保存和通知等授权。麦克风仅在 VIP 校验通过且你主动连接受支持的在线“我的设备”电脑时申请；已连成会话可在系统音频后台模式下继续并显示 iOS 麦克风指示，不会从后台新开或恢复。照片访问仅用于你主动选择的媒体以及保存你接收的媒体。拒绝某项权限只影响依赖它的功能。
On first launch, SendCat explains the processing purpose, method, and scope before starting local discovery, receive listeners, clipboard listening, and shared-file handling. It requests local-network, microphone, photo read/save, and notification authorization only as needed. Microphone access is requested only after VIP verification and your active connection to a supported online computer in My Devices. A live session may continue under the system audio background mode while iOS shows its microphone indicator; it never starts or resumes from the background. Photo access is limited to media you choose and media you save after receiving. Denying a permission affects only the dependent feature.
8. Third-Party Services
Apple 和 App Store 按其规则处理购买、订阅、退款、交易验证和恢复购买。只有当你明确点击发送反馈时，反馈接口服务商才会为传输与保存该反馈处理必要网络信息和提交内容。发送猫未集成广告或跨应用追踪 SDK，也不会把本机连接诊断作为遥测静默上传。
Apple and the App Store process purchases, subscriptions, refunds, transaction verification, and restoration under their rules. Only when you explicitly tap Send for feedback does the feedback endpoint provider process the network information and content required to transmit and retain it. SendCat integrates no advertising or cross-app tracking SDK and does not silently upload local connection diagnostics as telemetry.
9. Retention, Deletion, And Correction
传输记录、设备关系、配对资料、会员权益、购买摘要、剪贴板发送次数和偏好设置保存在你的设备中。你明确提交的反馈及附带诊断信息仅在客服回复、问题排查和合规所需期限内保存。你可以清理本地历史、移除设备关系、关闭接收或同步开关，或联系我们处理已经提交的反馈信息。
Transfer history, device relationships, pairing material, membership entitlements, purchase summaries, clipboard-send counts, and preferences stay on your device. Feedback and attached diagnostics you explicitly submit are retained only as needed for support, troubleshooting, and compliance. You may clear local history, remove relationships, disable receiving or sync, or contact us about feedback already submitted.
10. Security Measures
发送猫通过设备关系、配对密钥、局域网连接校验、AES-GCM 加密、必要的回声过滤、接口校验和访问控制等方式降低误传、未授权接收、内容回流、订单伪造和接口滥用风险。但任何网络传输和系统剪贴板都无法保证绝对安全，请只与可信设备建立关系并在可信网络环境下传输敏感内容。
SendCat uses device relationships, pairing keys, local-network connection checks, AES-GCM encryption, necessary echo filtering, API validation, and access controls to reduce risks of accidental delivery, unauthorized receiving, content loopback, forged orders, and API abuse. No network transfer or system clipboard can be absolutely secure, so please establish relationships only with trusted devices and transfer sensitive content only in trusted network environments.
11. Policy Updates
