 身份按主机名和端口分开保存，备份与设备迁移不包含应用数据。密码不写入连接记录，仅在明确开启“保存密码”后写入独立加密存储；未开启时仅用于当前会话。连接成功通知只处理一次，重复的传输就绪回调不会再次保存密码或重建会话页面；密码存储拒绝空值覆盖。旧版本已被空值覆盖的密码无法恢复，遇到此记录时会提示重新输入一次，并保留“保存密码”开启状态。由于 MiniRTC 的诊断日志包含登录身份，Android 桥接层关闭其会话日志。身份存储损坏会显示错误，不会静默重新注册。
 
-会话中的“剪贴板”发送用户输入的文本；收到的远端文本先留在会话内，点击“复制远端文本”才写入手机剪贴板。退出会话后清除会话内容。每次发送最多 128 KB。电脑键盘的 Ctrl / Win / Alt / Shift 可锁定组合键；macOS 的 Command 对应 Win。系统键盘通过 `supports_text_input` 检测远端能力，支持 UTF-8 的 macOS 被控端可直接输入中文、表情和听写文本；其他端或旧版使用 ASCII 按键回退，不支持的文本会提示使用剪贴板，不会先删除远端内容。输入法尚未确认的组字不会发送，自动纠错仅替换已发送文本的变化后缀；点击远端、收起、切换键盘或进入后台会清除本地输入上下文。

 “发送文件”调用系统文件选择器，后台读取所选文件后使用桌面端相同的 `file` / `file_feedback` 协议传输，支持空文件和中文文件名。每次发送一个文件，以 64 KiB 分块、最多 1 MiB 未确认数据限制发送队列；进度来自接收端确认，30 秒没有有效进展则报告失败。接收时校验大小并追踪完整字节范围，允许跨线程回调乱序，未完成的文件不会提供保存入口。同名文件分开存储，不覆盖已有文件；可通过“保存收到的文件”导出最近收到的文件，连续接收多个文件时应逐个保存。
