维点图书馆（DimensionsCosmos Library，以下简称「本站」）是一个用于在线阅读中国古典文献原文的静态网站与应用。 我们尽量把隐私做到最简：本站不设注册登录，不建立用户画像，不出售任何个人数据。本政策说明本站会接触哪些信息、这些信息存放在哪里，以及你可以如何清除它们。
一、我们是谁
本站由个人开发者独立运营，站点域名为 dimensionscosmos.pages.dev（正式域名启用后将同步更新本页）。 任何与隐私相关的问题，可发送邮件至 dimensionscosmos@outlook.com。
二、我们不收集什么
- 本站没有账号系统，不需要姓名、手机号、邮箱或任何身份信息即可阅读全部免费内容。
- 本站不接入广告 SDK、不做跨站追踪、不做行为画像，也不使用 Cookie 进行个性化推荐。
- 本站不读取你的通讯录、位置、相机、麦克风、相册或设备上的其他文件。
三、存放在你设备上的数据（本地存储）
为了让已购买的内容可以离线反复阅读，本站会在你的浏览器或应用沙盒内写入少量本地数据。这些数据不会上传到我们的服务器：
- 解锁凭证：键名
dc_unlocks，保存你已购买的「书籍 × 方法」组合对应的解锁码。解锁校验完全在你的设备上完成。 - 离线缓存：本站作为可安装应用（PWA）运行时，Service Worker 会把页面、样式、图标与书籍文本缓存到本地，用于断网阅读。
如何清除：在浏览器「设置 → 网站数据 / 存储」中找到本站并清除站点数据，或在应用内卸载本站即可。 清除后，已购买的解锁码将从该设备移除；如需恢复，请保留购买时收到的解锁码并重新输入。
四、第三方服务
本站自身不设数据库、不记录阅读行为。以下第三方在处理过程中可能接触到有限的技术信息：
- 托管与分发（Cloudflare Pages）：本站静态文件由 Cloudflare 托管。与所有网站一样，其边缘节点会接收访问请求， 可能记录 IP 地址、请求时间、User-Agent 等技术日志，用于分发与安全防护。相关处理适用 Cloudflare 自身的隐私政策。
- 字体（Google Fonts）：页面引用 Google Fonts 提供的在线字体，加载时你的浏览器会向
fonts.googleapis.com 发起请求， 该请求会暴露 IP 地址。若你希望完全避免这一外部请求，可在浏览器中启用字体拦截，或使用离线模式（已缓存的字体不受影响）。 - 支付（第三方收款平台）：付费解锁通过第三方收款平台完成（当前为面包多，国际渠道为 Gumroad）。 支付过程中的姓名、支付账号、账单信息由收款平台直接处理，本站不接触、不存储任何银行卡号或支付凭据。 收款平台的隐私政策适用于该环节。
五、我们不会做的事
- 不会出售、出租或交易你的任何信息。
- 不会向你发送营销邮件或推送（本站没有消息推送权限）。
- 不会基于你的阅读记录做用户画像或定向推荐。
六、未成年人
本站内容面向一般读者，不针对儿童设计，也不会有意收集儿童的个人信息。 由于本站不设账号、不收集身份信息，正常使用不会产生儿童个人数据。若家长或监护人认为存在相关问题，请联系我们处理。
七、你的权利
由于本站不保存你的个人信息，你无需申请导出或删除数据——清除设备上的站点数据即可彻底移除本站留下的全部痕迹。 如你对本站的数据处理方式仍有疑问、异议或投诉，可随时通过上方邮箱联系，我们会在合理期限内答复。
八、内容来源与 AI 生成说明
本站收录的原文主要来自中文维基文库等开放来源（遵循 CC BY-SA 4.0 等相应许可），版权归原作者与整理者所有。 站内不包含由 AI 模型生成的解读内容；原文之外的底本状况标注（如缺章、缺字提示）由程序依据底本数据生成，可能存在偏差，仅供阅读参考，不构成专业建议。
九、政策更新
若本站新增功能（如账号、评论、统计）导致数据处理方式发生变化，我们会在本页更新政策并修改上方的生效日期。 重大变更会在站内显著位置提示。建议你在使用前不定期查阅本页。

English Version
DimensionsCosmos Library (the "Site") is a static website and installable app for reading classic texts in their original form. We keep privacy as simple as possible: there are no accounts, no user profiling, and no sale of personal data.This policy explains what information the Site touches, where it is stored, and how you can remove it.
1. Who we are
The Site is independently operated by an individual developer and is currently served at dimensionscosmos.pages.dev. For any privacy question, contact dimensionscosmos@outlook.com.
2. What we do not collect
- There is no account system. No name, phone number, email address, or identity information is required to read free content.
- We use no advertising SDKs, no cross-site tracking, and no behavioural profiling, and we do not use cookies for personalised recommendations.
- We do not access your contacts, location, camera, microphone, photo library, or other files on your device.
3. Data stored on your device (local storage)
So that purchased content remains readable offline, the Site writes a small amount of data into your browser or app sandbox. This data is never uploaded to our servers:
- Unlock credentials — key
dc_unlocks, reserved for future paid content unlock codes. Verification happens entirely on your device. - Offline cache — when the Site runs as an installed app (PWA), a Service Worker caches pages, styles, icons, and book texts locally for offline reading.
How to remove it: clear site data for this Site in your browser settings, or uninstall the app. After clearing, purchased unlock codes are removed from that device; keep the codes you received at purchase so you can re-enter them.
4. Third-party services
The Site runs no database and does not log your reading activity. The following third parties may process limited technical information:
- Hosting and delivery (Cloudflare Pages) — static files are hosted by Cloudflare. As with any website, its edge network receives requests and may log IP address, request time, and User-Agent for delivery and security purposes. Cloudflare's own privacy policy applies.
- Fonts (Google Fonts) — pages load web fonts from Google Fonts, so your browser makes a request to
fonts.googleapis.com, which exposes your IP address. If you prefer to avoid this external request, you may block web fonts in your browser; offline mode is unaffected for already-cached fonts. - Payments (third-party checkout platforms) — paid unlocks are processed by third-party platforms (Mbd.pub for domestic payments, Gumroad for international). Names, payment accounts, and billing details are handled directly by those platforms; we never receive or store card numbers or payment credentials. Their privacy policies apply to that step.
5. What we will never do
- We do not sell, rent, or trade any of your information.
- We do not send marketing emails or push notifications (the app requests no notification permission).
- We do not build profiles or targeted recommendations from your reading history.
6. Children
The Site is intended for a general audience, is not directed to children, and does not knowingly collect personal information from children. Because there are no accounts and no identity collection, ordinary use does not generate children's personal data. Parents or guardians with concerns may contact us.
7. Your rights
Because we store no personal information about you, there is nothing to export or delete on our side —clearing site data on your device removes everything the Site has left behind. If you still have questions, objections, or complaints about our data practices, contact us at the address above and we will respond within a reasonable period.
8. Content sources and AI-generated material
Source texts are drawn mainly from open repositories such as Chinese Wikisource (under licenses including CC BY-SA 4.0); copyright remains with their authors and compilers. Some interpretive commentary is produced with the assistance of AI models and then processed through our pipeline. AI-generated material may contain inaccuracies and is provided for reading reference only, not as professional advice.
9. Changes to this policy
If new features (such as accounts, comments, or analytics) change how data is handled, we will update this page and revise the effective date above. Material changes will be announced prominently on the Site. Please review this page from time to time.
