Data Collection

数据收集

• Your notes are stored only on your device and in your personal iCloud account.
• 您的笔记仅存储在您的设备和个人 iCloud 账户中。
• We do not collect, store, or have any access to your personal data or note content.
• 我们不收集、存储或访问您的个人数据或笔记内容。
• No advertising or user-tracking SDKs are used, and we never build an advertising profile of you.
• 应用内不使用任何广告或用户追踪 SDK，也绝不为您建立广告画像。
• Crash & diagnostics: In release builds we use Sentry to collect crash reports, app-hang (freeze) reports, MetricKit stability signals, and a sampled share of performance traces. This helps us fix bugs. It includes device model, OS version and error logs, but never your note content or API keys — and it is not linked to your identity or used for tracking.
• 崩溃与诊断：在正式版中，我们使用 Sentry 收集崩溃报告、应用挂起（卡死）报告、MetricKit 稳定性信号，以及按采样比例的性能追踪，用于修复问题。其中包含设备型号、系统版本和错误日志，但绝不包含您的笔记内容或 API Key——且不与您的身份关联、不用于追踪。

iCloud Sync

iCloud 同步

• iCloud sync is entirely optional and can be disabled at any time in Settings.
• iCloud 同步完全可选，您可以随时在设置中关闭。
• When enabled, your data is synced through your own Apple iCloud (CloudKit private database) and protected by Apple's iCloud security — encrypted in transit and at rest on Apple's servers.
• 启用后，数据通过您自己的 Apple iCloud（CloudKit 私有数据库）同步，并受 Apple iCloud 安全机制保护——在传输过程中及存储于 Apple 服务器时均经过加密。
• The sync stays inside your personal iCloud account. Jotaid developers have no access to it — only you do.
• 同步数据始终保留在您个人的 iCloud 账户内。Jotaid 开发者无法访问，只有您自己能访问。

Permissions & System Access

权限与系统访问

• Images: Inserted via clipboard paste only. The app does not request access to your camera or photo library.
• 图片：仅通过剪贴板粘贴插入。应用不请求访问相机或照片库权限。
• iCloud: Used optionally to sync notes across your Apple devices.
• iCloud：可选，用于在您的 Apple 设备间同步笔记。
• Network: To render math, the app loads the KaTeX and MathJax libraries on demand from the jsdelivr CDN (pinned versions, integrity-checked); your note content is never sent to them. Mermaid diagrams render entirely on-device with no network request. The app also makes network connections in other cases, including: optional iCloud sync; opt-in AI (to the provider you choose); fetching a remote image from its source address when a note references one; and reaching an external website when you open a link or use the built-in browser. These connections go to the third-party address involved, not to Jotaid servers.
• 网络：渲染数学公式时，应用会按需从 jsdelivr CDN 加载 KaTeX 和 MathJax 渲染库（固定版本、完整性校验），且绝不向其发送您的笔记内容。Mermaid 图表完全在设备本地渲染，不发起任何网络请求。应用还会在下列情况联网，包括：可选的 iCloud 同步；主动开启的 AI（连接您所选的服务商）；当笔记包含远程图片时，向该图片的来源地址请求图片；以及当您打开外部链接或使用内置浏览器时，连接对应的网站。这些连接指向相关的第三方地址，而非 Jotaid 服务器。

AI Features

AI 功能

• AI features are optional and off by default. They are powered by third-party providers (OpenAI, Anthropic, Google, DeepSeek) using your own API key. You may also configure a custom OpenAI-compatible provider (for example a self-hosted or local model).
• AI 功能为可选项，默认关闭。由第三方服务商（OpenAI、Anthropic、Google、DeepSeek）驱动，使用您自己的 API Key。您也可以配置自定义的 OpenAI 兼容服务商（例如自建或本地模型）。
• Your API key is stored in the device Keychain — never transmitted to Jotaid servers.
• 您的 API Key 存储在设备 Keychain 中，不会传输到 Jotaid 服务器。
• When you trigger an AI action, the selected note content and context are sent directly to the provider you chose, governed by that provider's privacy policy. Nothing is sent without your explicit action, and no AI traffic passes through Jotaid servers.
• 当您触发 AI 操作时，选中的笔记内容与上下文会直接发送给您所选的服务商，并受该服务商的隐私政策约束。未经您主动操作不会发送任何内容，且所有 AI 流量都不经过 Jotaid 服务器。
• For a custom provider, remote endpoints must use HTTPS (plain HTTP is allowed only for localhost). You choose the endpoint, so any data sent to a custom endpoint is under your control and responsibility.
• 对于自定义服务商，远程 endpoint 必须使用 HTTPS（明文 HTTP 仅允许用于 localhost 本地）。endpoint 由您指定，因此发送到自定义 endpoint 的任何数据均由您自行掌控并负责。

Share Extension

分享扩展

• When you share text, a URL or an image into Jotaid from another app, the Share Extension reads that shared content and saves it as a note in Jotaid's shared on-device App Group storage. If you have iCloud sync enabled and available, that note then syncs to iCloud under the same rules as your main library.
• 当您从其他应用把文本、链接或图片分享到 Jotaid 时，分享扩展会读取该分享内容并将其保存为笔记，存入 Jotaid 的共享 App Group 本地存储。若您已启用且 iCloud 可用，该笔记会按主笔记库的相同规则同步到 iCloud。
• The Share Extension runs in its own process and includes the same Sentry crash and app-hang reporting as the main app. It never sends your shared content anywhere except your own note storage.
• 分享扩展在独立进程中运行，包含与主应用相同的 Sentry 崩溃与挂起报告。它绝不会把您的分享内容发送到您自己的笔记存储之外的任何地方。

Backups & Exports

备份与导出

• Backup files exported from Jotaid are encrypted with AES-GCM before being written to disk.
• 从 Jotaid 导出的备份文件在写入磁盘前经过 AES-GCM 加密处理。
• You are responsible for securing exported files stored outside the app.
• 存储在应用外部的导出文件，由您自行负责安全保管。
• If you choose to export a diagnostic report to help with support, it contains device, error and redacted log information (never your note content). It is written as a plain file, so only share it with someone you trust.
• 若您选择导出诊断报告以协助支持排查，其中包含设备、错误与脱敏后的日志信息（绝不含笔记内容）。该文件以明文形式生成，请仅分享给您信任的对象。

Data Deletion

数据删除

• Deleting the app from your device removes all locally stored data.
• 从设备删除应用将清除所有本地存储的数据。
• iCloud data can be deleted via: Settings → [Your Name] → iCloud → Manage Storage → Jotaid.
• iCloud 数据可通过以下路径删除：设置 → Apple ID → iCloud → 管理储存空间 → Jotaid。
