 ### Changed
 - **Skill catalog layout**: replace the two-column cards with scroll-safe installed and uninstalled lists; selecting a row now opens a full detail page where installation, Shortcut setup, and custom-skill editing are managed. / **技能目录布局**：将双列卡片改为可稳定滚动的已安装与未安装列表；点击列表项进入完整详情页，并统一管理安装、捷径配置与自定义技能编辑。
+- **Conversational skill replies**: make every built-in reply action favor short everyday chat language over formal email or support templates, and apply the active user-owned learned style only as a bounded wording-and-rhythm layer. / **口语化技能回复**：所有内置回复操作优先使用简短日常聊天表达，避免正式邮件与客服模板；当前用户自有的学习风格仅作为受限的用词与节奏层应用。
 
 ### Fixed
 - **Repeatable OOBE practice**: scope each free feature to one use per short-lived guided session, so returning to OOBE starts a fresh four-page experience without misreporting consumed-page conflicts as weak network; also simplify lesson titles, add a voice sample to read aloud, and streamline the completion page. / **可重复的 OOBE 体验**：将每项免费功能限制为每个短期引导会话使用一次，让用户重新进入 OOBE 时可以重新体验四个页面，并避免把页面已完成冲突误报为弱网；同时精简各环节标题，加入语音朗读示例，并简化完成页。

With a user-configured cloud engine, recordings are sent directly to that ASR provider. If you explicitly choose managed credits, recordings are sent through the OSGKeyboard managed gateway at <code>account.osglab.com</code> to the managed ASR provider for transcription. OSGKeyboard does not keep raw recordings after the request is processed.</li>
     <li><strong>Transcribed text and cursor context</strong> — after ASR, the transcript (not audio) may be sent for polish when you use a configured LLM or managed credits. A small amount of text around the cursor may be included to continue naturally. Secure fields are never captured, and cursor context is not written to logs or voice history. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>

Native speech and explicit user edits are used to infer recurring habits; historical prompts are supplied only to distinguish and remove AI-added style. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.

Native speech and explicit user edits are used to infer recurring habits; historical prompts are supplied only to distinguish and remove AI-added style. The generated prompt is shown for review and is not saved or activated until you confirm it. When you later invoke a conversational clipboard-reply skill while a reviewed user-created style is active, that style prompt is sent with the copied text so the reply can follow your wording and rhythm; built-in polish personalities are not attached. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>
     <li><strong>AI mode questions</strong> — in AI keyboard mode, your spoken question text—or a question you tap from an idle suggestion—is sent to the selected AI service to generate an answer. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>. When the selected service supports server-side web search, it may retrieve public web results for time-sensitive answers.</li>
     <li><strong>Anonymous onboarding AI trial</strong> — before you sign in, onboarding can issue a short-lived, feature-limited credential after Apple App Attest verifies a genuine app installation. The four fixed lessons may send one voice transcript, an explicitly copied lesson sample for translation and reply, and one transcribed AI question through <code>account.osglab.com</code>. This flow does not create an account, process an Apple identity token, use credits, or upload raw voice audio. The copied lesson sample is temporary and does not enable or populate clipboard history. The service keeps only pseudonymous integrity, request-state, feature, and metering records needed to enforce the one-use limits and investigate abuse; it does not retain request or response bodies.</li>
     <li><strong>AI suggestions and OSGKeyboard web pages</strong> — the main app may request public suggestion titles from <code>key.osglab.com</code>; no voice, transcript, clipboard body, API key, or ordinary keystroke content is included.

If you explicitly select managed credits, recordings go through the OSGKeyboard managed gateway at <code>account.osglab.com</code> to the managed ASR provider. Before the first switch to managed credits, the app explains that audio, text, nearby cursor context, and account data may leave the device and requires explicit agreement. OSGKeyboard does not retain raw recordings after processing.</li>
     <li><strong>Transcribed text and cursor context</strong> — after ASR, the transcript (not audio) may be sent for polish when you use a configured LLM or managed credits. To continue naturally at the insertion point, a small amount of text immediately before and after the cursor may be included. Secure fields are never captured; cursor context is not written to logs or voice history. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>. Without either path, raw local ASR text can still be inserted.</li>

     <li><strong>语音音频</strong> — 仅在你主动录音时采集。使用<strong>本地引擎</strong>时，音频在设备端完成转写，原始录音不会上传。使用用户自备云端服务时，录音会直接发送到你配置的识别服务商；若你明确选择「使用积分」，录音会经 <code>account.osglab.com</code> 的 OSGKeyboard 托管网关发送到托管识别服务商。首次切换托管积分前，App 会说明语音、文字、光标附近上下文与账号数据可能离开设备，并要求你明确同意。请求处理完成后，OSGKeyboard 不保留原始录音。</li>
     <li><strong>转写文字与光标上下文</strong> — 使用已配置的 LLM 或托管积分时，转写文字（非音频）可能发送润色，并可能包含光标附近少量文字以自然衔接。密码框不会采集，光标上下文不会写入日志或语音历史。用户自备请求直达所选服务商；托管积分请求经 <code>account.osglab.com</code> 处理。未选择任一路径时，仍可直接插入本地 ASR 原始文字。</li>
-    <li><strong>说话风格学习</strong> — 语音历史可同时保留界面展示的最终文本、可用时保留 AI 润色前且已经过确定性纠错的 ASR 文本，以及当次使用的润色风格 Prompt 去重快照；润色前文本不会在历史界面显示。只有当你主动点击「生成我的风格」后，符合条件的润色前后文本对及对应历史 Prompt 才会发送给你配置的 AI 服务。原生口述与用户明确编辑用于归纳反复出现的习惯；历史 Prompt 只用于识别并排除 AI 附加风格。用户自备请求直达所选服务商；托管积分请求经 <code>account.osglab.com</code> 处理。生成结果会先展示供你检查，确认保存前不会写入或启用。</li>

     <li><strong>AI 建议与 OSGKeyboard 网页</strong> — 主 App 可能从 <code>key.osglab.com</code> 请求公开建议标题；该请求不包含语音、转写、剪贴板正文、API Key 或普通击键内容。打开更新页时会从 <code>download.osglab.com</code> 请求公开内容。与普通 HTTPS 网站相同，相关主机与基础设施可能处理 IP 地址、请求时间等连接元数据。</li>
     <li><strong>AI Agent 技能、快捷指令与地图</strong> — 仅在你主动运行技能时，所选或复制的文字及技能提示词才会发送到你配置的 LLM 服务商。导出提醒事项、日历或备忘录时，生成结果会在设备端交给你安装的 Apple 快捷指令；OSGKeyboard 不会收到最终创建的项目。导航时，地址或路线会写入 URL 并交给 Apple 地图、高德地图或百度地图，相应地图服务商的政策适用。</li>
