User Agreement
欢迎使用发送猫。你访问本网站、安装、登录或使用发送猫，即表示你已阅读并同意本用户协议及隐私政策。如你不同意，请停止使用相关服务。
Welcome to SendCat. By visiting this website, installing, signing in to, or using SendCat, you acknowledge that you have read and agreed to this User Agreement and the Privacy Policy. If you do not agree, please stop using the related services.
1. Service Scope
本协议适用于发送猫网站、iOS/iPadOS、Android、HarmonyOS、Windows、macOS 及相关服务。设备发现和首次配对依赖局域网；受支持的文本、图片、视频和文件默认走局域网，也可在你先将电脑设为“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通过互联网传输。公网连接默认关闭，实时麦克风不走公网。不同平台的具体功能以实际客户端为准。
This agreement applies to SendCat clients and related services. Discovery and initial pairing require a local network. Supported text, images, videos, and files use the local network by default and may use the internet only after you add a computer to My Devices, configure a valid public HTTPS address or reverse proxy, and explicitly enable Public Connection. Public Connection is off by default, and live microphone audio never uses it.
设备发现：用于在同一局域网、个人热点或你授权的网络环境中发现并连接可信设备。
跨屏输入：用于把手机输入直接传到电脑，支持自动粘贴、回车和快捷发送。
传输能力：用于发送文本、剪贴板、截图、图片、文件、照片和视频，并显示传输状态。
手机麦克风：在移动端 VIP 权益校验通过后，由你主动把手机实时声音发送给在线且位于“我的设备”中的 Mac 或 Windows 电脑；电脑端不能远程开启手机麦克风，该功能与发送文本相互独立。
管理能力：用于设备关系管理、历史记录、提示词管理、会员状态管理、订单或购买状态展示和必要的安全校验。
反馈能力：用于提交 Bug、故障描述、投诉或建议。你选择提交 Bug 时，客户端可能随反馈一并发送最近 10 条诊断日志，以便定位问题；建议、普通咨询或投诉通常不默认附带日志，具体以提交界面的提示为准。
Device discovery:to discover and connect trusted devices on the same local network, personal hotspot, or other network environment you authorize.
Cross-device input:to send phone input directly to desktop, with auto-paste, Enter, and quick send support.
Transfer features:to send text, clipboard content, screenshots, images, files, photos, and videos, and to display transfer status.
Phone microphone:after the mobile app verifies VIP entitlement, you may explicitly send live phone audio to an online Mac or Windows computer in My Devices. A computer cannot remotely turn on the phone microphone, and this feature is independent from Send Text.
Management features:to manage device relationships, history, prompt fragments, membership status, order or purchase status display, and necessary security checks.
Feedback features:to submit bugs, troubleshooting descriptions, complaints, or suggestions. If you choose to submit a bug, the client may send the most recent 10 diagnostic logs with the report to help locate the issue. Suggestions, general inquiries, or complaints usually do not include logs by default, subject to the notice shown in the submission interface.
2. Desktop Large Model Integration
发送猫电脑端可能提供大模型接入能力。是否接入、接入哪一家大模型服务、填写或移除相关 API Key、令牌或本地模型配置，均由你自行选择和管理。不接入大模型不影响发送猫的基础发送、传输和跨屏输入功能。接入后，发送猫可以在你主动使用相关功能时，结合你的输入或本地上下文提供更智能的文本处理、提示词辅助或操作建议。
The SendCat desktop client may provide optional large language model integration. Whether to connect a model service, which provider to use, and whether to add or remove API keys, tokens, or local model settings are choices you make and manage yourself. Not connecting a large language model does not affect SendCat's basic sending, transfer, or cross-device input features. After integration, SendCat may use your active input or local context to provide smarter text processing, prompt assistance, or operation suggestions when you choose to use those features.
接入是可选的，是否开启、切换、删除或更换服务均由你决定。
API Key、令牌、服务地址和本地模型配置应由你自行保管，发送猫不替你管理第三方服务账户。
第三方大模型处理你的输入时，是否保存、训练或用于改进服务，取决于该服务自身规则，你应自行阅读其条款。
不接入大模型时，发送猫仍可正常提供局域网传输和跨屏输入基础能力。
Integration is optional, and whether to enable, switch, remove, or replace a service is your decision.
You should keep API keys, tokens, service endpoints, and local model settings under your own control; SendCat does not manage third-party service accounts for you.
Whether a third-party model saves, trains on, or uses your input to improve its service depends on that service's own rules, which you should review.
Without model integration, SendCat still provides basic local network transfer and cross-device input features.
3. Device Relationships And Authorization
“我的设备”表示你确认属于自己或由你管理的可信设备；“好友设备”表示你允许传输普通文本、图片或文件的设备；陌生设备仅在你主动选择、确认或完成必要配对后才能参与传输。你应确认正在连接和传输的设备属于自己或已取得合法授权。
My Devices means trusted devices that you confirm are owned or managed by you. Friend Devices means devices that you allow to receive ordinary text, images, or files. Unknown devices may participate in transfers only after you actively select, confirm, or complete necessary pairing. You must ensure that connected and transfer-target devices are yours or legally authorized.
我的设备：适合你本人日常使用的手机、电脑、平板等设备。
好友设备：适合你愿意互传普通内容但暂不完全开放的设备。
陌生设备：只有在你主动确认或完成配对后，才会参与传输。
授权责任：你应保证连接设备属于你本人、你管理的设备，或已取得合法授权。
My Devices:devices you personally use, such as phones, computers, and tablets.
Friend Devices:devices you allow to exchange ordinary content with, but not yet fully trust.
Unknown devices:devices that may participate only after you actively confirm or pair them.
Authorization responsibility:you must ensure connected devices belong to you, are managed by you, or are legally authorized.
4. Transfer Security
传输使用配对密钥派生的会话密钥进行 AES-GCM 加密。公网连接仅允许已有配对密钥的“我的设备”，使用你自行配置的 HTTPS 地址；发送猫不提供公网中转或云端存储。你选择的域名、代理、CDN、隧道或网络服务商可能处理公网 IP 和连接日志，电脑也可能在本机队列暂存待发送文件。实时麦克风仍仅通过局域网传输。公网单文件上限为 10 GiB。
Transfers use AES-GCM with keys derived from pairing keys. Public Connection is limited to paired My Devices and uses the HTTPS address you configure; SendCat provides no public relay or cloud storage. Providers you choose may process public IP addresses and logs, and the computer may temporarily stage outbound files locally. Live microphone audio remains local-network only. Public transfers are limited to 10 GiB per file.
加密范围：适用于剪贴板、图片、文件、实时麦克风音频和其他局域网传输内容。
校验方式：结合配对密钥、设备信息、会话信息和操作类型，降低伪造接收和中途篡改风险。
风险边界：加密并不能消除你把内容发给错误设备、授权给错误设备或在不可信网络中传输的风险。
使用建议：只对可信设备开启自动接收、自动粘贴或连续传输功能。
Encryption scope:applies to clipboard, images, files, live microphone audio, and other local network transfer content.
Validation method:pairing keys, device information, session information, and operation type are used to reduce forged receiving and tampering risks.
Risk boundary:encryption does not eliminate the risk of sending content to the wrong device, authorizing the wrong device, or transferring on an untrusted network.
Usage advice:enable auto-receive, auto-paste, or continuous transfer only for trusted devices.
5. Accounts, Sign-In, And Membership
发送猫的登录方式按平台、地区和分发渠道提供。中国大陆 Android 渠道可能支持手机号验证码、微信或 QQ 等应用内展示的登录方式；Google Play Android、iOS/iPadOS 和 HarmonyOS 版不提供手机号、微信或 QQ 登录。HarmonyOS 版不设发送猫应用账号，会员购买与恢复通过当前设备登录的华为账号和华为应用内支付处理；华为账号仅由华为用于应用市场和支付服务，不等同于登录发送猫。桌面端和其他客户端的登录、配对或会员状态展示方式，以对应客户端页面为准。你不应把某一平台或渠道的登录方式理解为所有平台均可使用。
SendCat sign-in methods are provided by platform, region, and distribution channel. Mainland China Android channels may support phone verification code, WeChat, QQ, or other sign-in methods shown in the app. The Google Play Android, iOS/iPadOS, and HarmonyOS versions do not support phone number, WeChat, or QQ sign-in. SendCat for HarmonyOS has no SendCat app account; membership purchase and restoration use the HUAWEI ID currently signed in on the device and Huawei In-App Purchases. Huawei uses that HUAWEI ID for AppGallery and payment services; it is not a sign-in to SendCat. Desktop and other clients may display sign-in, pairing, or membership status according to their own client pages. A sign-in method available on one platform or channel should not be understood as available on all platforms.
当前移动端 VIP 权益包括使用“把手机用作电脑麦克风”、在会员有效期内不限次数发送剪贴板，以及其他在应用内明确标注的 VIP 功能，具体以购买页和功能入口展示为准。麦克风权益由发起连接的手机所属平台校验；电脑端不单独开通该权益。非会员点击带锁的麦克风操作时只会看到会员开通提示，不会申请麦克风权限或发起连接；已经显示的停止操作不受会员门槛阻断。会员权益、购买记录、续费管理、取消方式、退款规则和恢复购买方式，以实际购买渠道、应用内说明和对应平台规则为准。中国大陆 Android 渠道、Google Play、Apple App Store、华为应用内支付或其他渠道的会员权益相互独立，不互通、不合并有效期，也不能跨平台恢复。一个 Android 账号或对应渠道账号最多可在应用内规则允许的设备数量内使用会员权益；超过限制时，可能需要移除旧设备后再使用新设备。不得出租、出借、转售、共享账号、Apple ID、Google 账号、华为账号或其他渠道账号，也不得通过模拟设备、篡改客户端、伪造订单、绕过校验等方式获取会员权益。
Current mobile VIP benefits include phone-as-computer-microphone, unlimited clipboard sends while membership is active, and other features explicitly marked VIP in the app, subject to the purchase page and feature entry. Microphone entitlement is verified by the platform of the phone that initiates the connection; the desktop does not separately activate this entitlement. Free users who tap the locked microphone action only see the VIP upgrade prompt; SendCat does not request microphone permission or start a connection. A visible Stop action is never blocked by the membership gate. Membership benefits, purchase records, renewal management, cancellation methods, refund rules, and purchase restoration methods are subject to the actual purchase channel, in-app descriptions, and applicable platform rules. Memberships from mainland China Android channels, Google Play, Apple App Store, Huawei In-App Purchases, or other channels are independent, do not share entitlements, do not merge validity periods, and cannot be restored across platforms. An Android account or corresponding channel account may use membership benefits only within the device limits allowed by the app rules. If the limit is exceeded, you may need to remove an old device before using a new one. You may not rent, lend, resell, or share accounts, Apple IDs, Google accounts, HUAWEI IDs, or other channel accounts, or obtain benefits through simulated devices, client tampering, forged orders, or bypassed verification.
