2. What Is SendCat
SendCat is a tool for transferring local network files, images, videos, text, and clipboard content between your own devices. The iOS and iPadOS client supports device relationship management, local network discovery, file sending, image/video sending, clipboard sync, and related features.
3. FAQ
Why is Local Network permission needed?
SendCat uses Local Network permission to find your other devices and transfer content directly over the same Wi-Fi network or personal hotspot. If this permission is denied, the app may open normally, but device discovery, pairing, and local transfer may fail.
Check permission:open iOS Settings, find SendCat, and make sure Local Network is enabled.
After changing it:force quit and reopen SendCat on both devices.
If the prompt does not appear:restart the device, then open SendCat again while connected to Wi-Fi.
What if devices cannot be found?
Network:make sure both devices are on the same Wi-Fi network or personal hotspot.
Permission:make sure SendCat is open on both devices and Local Network permission is allowed.
Isolation:make sure the other device is not blocked by a firewall, guest network, or router isolation.
VPN:turn off VPN, proxy, security filtering, or private relay features temporarily and try again.
Retry:restart the app, reconnect Wi-Fi, or restart the router if discovery still fails.
What if sending is slow, interrupted, or stuck?
Distance:keep both devices close to the Wi-Fi router or personal hotspot.
Screen state:keep SendCat open during large transfers, especially for videos or many files.
Network quality:avoid crowded public Wi-Fi, guest networks, and weak hotspot signals.
Large files:try sending fewer files at once, then resend failed items.
Why did the receiving device not show a notification?
Notifications depend on system permission and background restrictions. If no notification appears, open SendCat on the receiving device and check whether the content arrived in the app. Also make sure notifications are enabled for SendCat in system settings and that Focus or Do Not Disturb mode is not hiding alerts.
Why is clipboard sync not working?
Switch:make sure the related clipboard send or receive option is enabled in the app.
Permission notice:on newer iOS versions, the system may ask before an app reads pasted content.
Content type:some apps, password managers, or secure fields may block clipboard reading or shorten clipboard availability.
Trust:send clipboard content only to devices you recognize and trust.
What if photos or files cannot be selected or saved?
For selecting photos, videos, or files, SendCat relies on the system picker and the permission granted by your current selection. If saving fails, check photo library permission, available storage, file name compatibility, and whether the target app or folder allows writing.
How does membership work?
iOS and iPadOS membership takes effect through Apple App Store subscriptions or purchase records. SendCat verifies membership entitlements using Apple transaction records and necessary device identifiers, and does not require phone-number sign-in. If membership status does not update immediately after purchase, wait a short time, make sure the network is available, then use Restore Purchases in the membership page.
Does iOS / iPadOS membership carry over to other platforms?
No. iOS and iPadOS membership is based on Apple App Store subscription or purchase records. Memberships on other platforms follow their own platform rules. Membership validity is not shared, and purchases cannot be restored across platforms.
Is clipboard content uploaded to the server?
Clipboard sync transfers content between your devices. The local network is used by default; supported content may use Public Connection only after you configure a public HTTPS address or reverse proxy and explicitly enable it. SendCat does not use clipboard content for advertising profiles or provide a public relay.
Are files, photos, or videos stored on SendCat servers?
File, photo, and video transfer uses the local network by default. If you configure and enable Public Connection yourself, supported content travels over the internet directly to the selected computer through services you choose. It is not stored as account data by the SendCat login service. Public transfers are limited to 10 GiB per file.
How do I restore VIP purchases?
Sign in to the App Store with the Apple ID used for the purchase, then go to the membership page and tap Restore Purchases. If restoration fails, confirm that the purchase exists under the current Apple ID, check the network, restart the app, and try again. Purchases, subscription management, and refunds on iOS and iPadOS are handled by the Apple App Store, and SendCat restores membership entitlements based on Apple transaction records.
How do I cancel a subscription or request a refund?
If your purchase is an Apple App Store subscription, manage it in the Apple ID subscriptions page in iPhone or iPad Settings. Refund requests usually need to be submitted through Apple's official channels.
4. Data Deletion And Membership Records
The iOS and iPadOS client mainly stores transfer history, device relationships, and preferences on your device. You can clear local history, remove device relationships, turn off receiving or sync switches in the app, or uninstall the app to remove local data.
If you need help with membership entitlements, device bindings, feedback records, or other service-side data, contact us at gua@sendcat.link and provide information for request verification. Apple transaction, subscription, refund, and billing records are handled by Apple under its rules.
5. Feedback Checklist
App:app version number.
Device:device model, such as iPhone 15 or iPad Pro.
System:system version, such as iOS 18 or iPadOS 18.
Issue:steps to reproduce and screenshots.
Network:whether the devices are on the same Wi-Fi network or personal hotspot.
Purchase:for purchase issues, provide an Apple order screenshot or transaction time, but do not send Apple ID passwords or bank card information.

一、联系方式
支持、反馈、投诉、会员、隐私和数据删除请求，请联系 gua@sendcat.link。
请尽量说明 App 版本、设备型号、系统版本、问题发生步骤和截图。若涉及购买问题，可以提供 Apple 订单截图或交易时间。不要发送 Apple ID 密码、验证码、银行卡信息或其他敏感凭据。
二、发送猫是什么
发送猫是一款用于在你自己的设备之间进行局域网文件、图片、视频、文本和剪贴板传输的工具。iOS / iPadOS 客户端支持设备关系管理、局域网发现、文件发送、图片/视频发送、剪贴板同步等功能。
三、常见问题
为什么需要本地网络权限？
发送猫需要本地网络权限，才能在同一 Wi-Fi 或个人热点下发现你的其他设备，并直接在设备之间传输内容。如果拒绝这个权限，App 可能可以正常打开，但设备发现、配对和局域网传输会失败。
检查权限：打开 iOS 系统设置，找到发送猫，确认“本地网络”已经开启。
修改后：在两台设备上都彻底关闭发送猫，再重新打开。
没有弹窗：重启设备，连接 Wi-Fi 后再打开发送猫。
找不到设备怎么办？
网络：确认两台设备连接到同一个 Wi-Fi 或同一个个人热点。
权限：确认发送猫在两台设备上都已打开并允许本地网络权限。
隔离：确认对端设备没有被防火墙、访客网络或路由器隔离。
VPN：临时关闭 VPN、代理、安全过滤、专用中继等网络功能后再试。
重试：关闭并重新打开 App，重新连接 Wi-Fi；如果仍然找不到，可以重启路由器。
发送很慢、中断或一直卡住怎么办？
距离：让两台设备尽量靠近 Wi-Fi 路由器或个人热点。
前台：传大视频或大量文件时，尽量保持发送猫在前台打开。
网络：避免使用信号弱、人数多的公共 Wi-Fi、访客网络或不稳定热点。
大文件：一次少传一些文件，失败的内容可以单独重新发送。
接收设备没有弹出通知怎么办？
通知是否出现，取决于系统通知权限和后台限制。可以先打开接收设备上的发送猫，查看内容是否已经到达；同时确认系统设置里已经允许发送猫通知，并检查专注模式、勿扰模式是否隐藏了提醒。
剪贴板同步没反应怎么办？
开关：确认 App 内相关的剪贴板发送或接收开关已经开启。
系统提示：较新的 iOS 版本可能会在 App 读取粘贴内容前弹出确认提示。
内容限制：部分 App、密码管理器或安全输入框可能会限制剪贴板读取，或让剪贴板内容很快失效。
可信设备：只把剪贴板内容发送给你认识并信任的设备。
照片或文件无法选择、无法保存怎么办？
选择照片、视频或文件时，发送猫使用系统选择器，并依赖你本次选择授予的访问权限。如果保存失败，请检查照片权限、设备剩余空间、文件名是否兼容，以及目标 App 或文件夹是否允许写入。
会员如何生效？
iOS / iPadOS 会员通过 Apple App Store 订阅或购买记录生效。发送猫会根据 Apple 交易记录和必要的设备标识校验会员权益，不要求手机号登录。如果购买后会员状态没有立刻更新，可以等待一小会儿，确认网络正常后，在会员页面使用“恢复购买”。
iOS / iPadOS 会员和其他平台会员互通吗？
不互通。iOS / iPadOS 会员以 Apple App Store 的订阅或购买记录为准；其他平台会员按对应平台规则生效。不同平台会员不共享有效期，也不能跨平台恢复购买。
剪贴板内容会上传服务器吗？
剪贴板同步用于你的设备之间传输，默认走局域网；只有你自行配置 HTTPS 公网地址或反向代理并主动开启后，受支持的内容才会使用公网连接。发送猫不提供公网中转，也不会将剪贴板内容用于广告画像。
文件、照片、视频会保存到发送猫服务器吗？
发送猫的文件、照片和视频默认在设备间通过局域网传输；你自行配置并开启公网连接后，受支持的内容会经过你选择的网络服务直达指定电脑，不作为账号数据保存到发送猫登录服务。公网单文件上限为 10 GiB。
如何恢复 VIP 购买？
请使用购买时的 Apple ID 登录 App Store，然后进入会员页面点击“恢复购买”。如果恢复失败，请确认当前 Apple ID 下确实有对应购买记录，检查网络，重启 App 后再试。iOS / iPadOS 购买、订阅管理和退款由 Apple App Store 处理，发送猫会根据 Apple 交易记录恢复会员权益。
如何取消订阅或申请退款？
如果你购买的是 Apple App Store 订阅，请在 iPhone 或 iPad 的系统设置中进入 Apple ID 订阅页面管理。退款请求通常需要通过 Apple 官方渠道提交。
四、数据删除与会员记录
iOS / iPadOS 客户端主要在本机保存传输历史、设备关系和偏好设置。你可以在 App 内清理本地历史、移除设备关系、关闭接收或同步开关，也可以卸载 App 删除本机数据。
如果你需要处理会员权益、设备绑定、反馈记录或其他与服务端有关的数据，请通过 gua@sendcat.link 联系我们，并提供可用于核实请求的信息。Apple 交易、订阅、退款和账单记录由 Apple 按其规则处理。
