This Privacy Policy describes how SuperMark (“we”, “us”) handles information when you use the SuperMark browser extension and related membership services operated under SeedPower. 本隐私政策说明 SuperMark（“我们”）在你使用 SuperMark 浏览器扩展及 SeedPower 相关会员服务时如何处理信息。
1. What SuperMark is1. 产品说明
SuperMark is a browser extension that displays and helps you manage your browser bookmarks on the new tab page. Optional paid membership tiers (such as Pro and Premium) are sold as digital subscriptions. SuperMark 是一款在新标签页展示并协助管理浏览器书签的扩展。 可选的付费会员档位（如 Pro、Premium）以数字订阅形式销售。
2. Data we process2. 我们处理的数据
- Bookmarks & browsing data (local): Bookmark titles, URLs, and folder structure are read and written through the browser bookmark API and stay in your browser unless you export them or explicitly create a share link. We do not upload your full bookmark library by default. 书签与浏览数据（本地）：书签标题、URL 与文件夹结构通过浏览器书签 API 读写，默认保存在本地。除非你导出或主动创建分享链接，我们不会上传你的完整书签库。
- Shared folders (optional): If you use Share, a snapshot of the selected folder (titles and URLs) is uploaded to create a public or password-protected private link on supermark.seedpower.app. Anyone with a public link—or the password for a private link—can view that snapshot. 分享文件夹（可选）：若使用「分享」，所选文件夹的快照（标题与 URL）会上传以生成公开或需密码的私密链接（托管于 supermark.seedpower.app）。任何人持有公开链接，或私密链接的密码，均可查看该快照。
- Preferences (local / optional sync): Theme, wallpaper, quick links, todos, notes, and similar settings are stored in browser storage. If you enable Chrome sync, some preferences may sync via your Google Chrome account. 偏好设置（本地 / 可选同步）：主题、壁纸、快捷链接、待办、便签等保存在浏览器存储。若开启 Chrome 同步，部分偏好可能经你的 Chrome 账号跨设备同步。
- Account data (if you sign in): When you sign in with Google, we store your Google account identifier, email, display name, and profile picture as needed to authenticate you and manage membership status. 账户数据（若登录）：使用 Google 登录时，我们会保存用于身份验证与会员管理的 Google 账号标识、邮箱、显示名称与头像。
- Billing data: Payments for paid memberships are processed by Creem. Creem may process payment method details, billing address, and tax information as Merchant of Record. We receive subscription status and related identifiers needed to unlock plan features—not your full card number. 账单数据：付费会员付款由 Creem 作为 Merchant of Record 处理，可能包括支付方式、账单地址与税务信息。我们仅接收用于解锁对应档位的订阅状态及相关标识，不会保存完整卡号。
- AI features (optional): If you use AI Organize, AI Recommend, or AI Website Intro, selected bookmark titles/URLs or page metadata may be sent to our hosted AI pipeline (Pro/Premium quotas) or—to a provider you configure when using Premium custom model providers (BYOK). BYOK API keys stay on your device. AI 功能（可选）：若使用 AI 一键整理、AI 推荐书签或 AI 站点介绍，你选中的书签标题 / URL 或页面元数据可能发送至我们的托管 AI 通道（Pro / Premium 额度）；若使用 Premium 自定义模型提供者（BYOK），则会发送到你配置的接口，API Key 仅保存在本地。
- Diagnostics & product analytics: We use Sentry for crash/error reports and PostHog for anonymized product usage events (for example install, new-tab open, and sign-in). Events may include extension version, coarse technical context, and—if you are signed in—an account identifier so we can understand plan usage. We do not send your bookmark library contents to these services. 诊断与产品分析：我们使用 Sentry 收集崩溃与错误报告，使用 PostHog 收集匿名化的产品使用事件（例如安装、打开新标签页、登录）。事件可能包含扩展版本、粗粒度技术上下文；若你已登录，还可能包含账户标识以便了解档位使用情况。我们不会把完整书签库内容发送给这些服务。
