Quantara is a free educational tool for Purple Star Astrology (Zi Wei Dou Shu). This Privacy Policy explains, in plain language, what happens to your information. The short version: your personal details never leave your device.
Quantara is a static, front-end-only website. When you enter your name, birth date, birth time, or gender, those details are processed entirely inside your own web browser to calculate your chart. They are stored only in your browser's local storage on your device. We do not transmit, collect, or store this information on any server. We never see it.
Quantara has no login or account system, no paid features, no advertising, and no sponsors at this time. We do not ask you to register, and we have nothing to "sell" because we hold none of your data. If sponsored content is ever introduced in the future, we will update this policy first and clearly label any sponsored material.
We do not install third-party tracking pixels, advertising cookies, or behavioural analytics. Quantara is hosted on Cloudflare Pages, and we use Cloudflare Web Analytics — a privacy-first measurement tool that does not use cookies and does not track individuals. It gives us only anonymous, aggregated statistics (such as page views), so we can know whether anyone is using the site. We cannot use it to identify or profile you.
Quantara lets you generate a share card or a chart link. You decide whether to share anything. A chart link contains only birth-date, birth-time, and gender parameters needed to redraw the chart — it does not contain your name. Anyone you send a link to can recreate that chart, so share thoughtfully.
Because your data lives only in your browser, you are in full control. You can delete everything at any time by clearing your browser's local storage / site data, or by using your browser's "clear data" function. There is no server-side copy for us to delete on your behalf.
Quantara is intended for users aged 13 and over and is not directed at children. We do not knowingly process data from children under 13. As we collect no data, we cannot identify a user's age; please do not use Quantara if you are under 13.
Because Quantara does not collect, transmit, or store personal data on any server and uses no tracking cookies, most data-controller obligations do not arise in practice. Where any rights under the GDPR (EU/UK) or CCPA/CPRA (California) could apply, you can exercise full control directly: your data is on your device and you may delete it yourself at any time. For questions, contact us at [email protected].
If our practices change (for example, if new analytics or sponsored content are ever introduced), we will update this policy and revise the date below.

Quantara 是一個免費的紫微斗數教育工具。本政策用白話說明您的資訊會發生什麼事。一句話總結：您的個人資料絕不會離開您的裝置。
Quantara 是純前端的靜態網站。當您輸入姓名、出生日期、出生時辰或性別時，這些資料完全在您自己的瀏覽器內完成命盤計算，並只儲存在您裝置的瀏覽器本機儲存空間（localStorage）。我們不會把這些資訊傳輸、收集或儲存在任何伺服器上。我們看不到它們。
Quantara 目前沒有登入或帳號系統、沒有付費功能、沒有廣告、也沒有任何贊助商。我們不要求您註冊；由於我們不持有您的任何資料，也沒有任何資料可供「販售」。未來若引入贊助內容，我們將先更新本政策，並明確標示任何贊助素材。
我們不安裝第三方追蹤像素、廣告 cookie 或行為分析工具。Quantara 託管於 Cloudflare Pages，並使用 Cloudflare Web Analytics——一個隱私優先的流量統計工具，不使用 cookie、不追蹤個人，只提供匿名彙總數據（例如瀏覽次數）。它無法用來識別您或建立您的輪廓。
Quantara 可讓您產生分享卡片或命盤連結。是否分享，完全由您決定。命盤連結僅包含重畫命盤所需的出生日期、時辰與性別參數，不包含您的姓名。收到連結的人都能重現該命盤，請審慎分享。
由於您的資料只存在您的瀏覽器中，主導權完全在您手上。您可隨時清除瀏覽器的本機儲存／網站資料來刪除一切。我們手上沒有任何伺服器端副本需要代您刪除。
Quantara 適用對象為 13 歲以上，並非以兒童為導向。由於我們不收集任何資料，無法判斷使用者年齡；若您未滿 13 歲，請勿使用 Quantara。
由於 Quantara 不在任何伺服器上收集、傳輸或儲存個人資料，也不使用追蹤型 cookie，多數資料控管者義務在實務上並不發生。您的資料就在您的裝置上，您可隨時自行刪除。如有疑問，請來信 [email protected]。
若我們的做法有所改變，我們會更新本政策並修訂日期。
