InkTrace — Privacy Policy
Effective date: 28 March 2026 · Chrome extension listing ID: fkciapipohelkbfahdacfpckeobdlnao
This policy describes how the InkTrace browser extension (“InkTrace”, “we”, “us”)
treats personal and sensitive user data when you use it. InkTrace is published by the Taixu project
(taixu.app). If anything here conflicts with the Chrome Web Store edition you installed,
the behavior of that build (no remote analytics or server-side analysis to our infrastructure) is what applies.
This document explains user data collection, user data handling, user data storage, and user data sharing for InkTrace.
The numbered sections below correspond to those four topics.
User data collection
We do not operate a backend that collects account profiles, contact lists, or browsing history for advertising.
To provide writing-process analysis on Google Docs, the extension accesses:
- Google Docs revision history for the active document — retrieved using your existing Google session from Google’s servers. This may include document text and edit metadata needed to replay the writing process.
- Document title — read so it can be shown in the analysis UI.
- Technical context — the extension uses Chrome extension APIs (for example
activeTab, tabs) to know when you are on a Google Docs document page and to open the analysis tab.
Chrome Web Store build: We do not send your document contents or revision payloads to servers operated by Taixu for processing or logging.
Analysis runs locally in your browser.
Separate “full” distribution (not from the Chrome Web Store): A non-Store build may offer optional server-assisted analysis.
That feature is disabled in the Store build. If you use such a build, any transmission is limited to what that feature requires and is described in its in-product disclosure.
User data handling
Data accessed from Google Docs is used only to:
- Replay revisions and compute writing-process indicators (for example timing, paste-related signals, and related statistics) on your device.
- Display results and export reports (for example PDF) on your device, according to the actions you take in the extension.
We do not use this data for automated decision-making about you, credit scoring, or employment. We do not build cross-site profiles of users.
User data storage
The extension stores only your language preference (Chinese / English) in the browser’s
localStorage under a key specific to InkTrace. No document body, revision blobs, or student names are persisted by us in that storage.
While you use the analysis view, document-related data may exist temporarily in memory. Closing the analysis tab or your browser clears that session state from the extension’s perspective; Google continues to store your document under your Google account according to Google’s own terms.
Retention: The language preference remains until you remove it (for example by clearing site data for the extension pages or uninstalling the extension).
User data sharing
We do not sell, rent, or trade your personal information. We do not share document content or revision history with data brokers.
Google: Revision data is obtained from Google’s services using your Google account; Google’s privacy policy and terms govern data held by Google.
Legal: We may disclose information if required by applicable law or a valid legal process, and only to the extent we are legally compelled.
Extension permissions (Chrome)
activeTab — detect when you are on a Google Docs document page.
tabs — open the analysis page in a tab and avoid duplicate tabs.
- Host access to
https://docs.google.com/* — read revision data needed for analysis.
The Chrome Web Store package does not request network access to taixu.app for core analysis.
Your choices and rights
You can stop using the extension, remove it from Chrome, or clear stored preferences via your browser’s settings.
Because we do not maintain per-user accounts on our servers for the Store build, there is no separate “account deletion” flow on our side for extension usage data — we do not hold that data centrally.
Depending on your region, you may have rights to access, correct, or object to processing of personal data. Contact us using the details below; we will respond in line with applicable law.
Children
InkTrace is intended for educators and related workflows. It is not directed at children under 13, and we do not knowingly collect personal information from children for commercial purposes through this extension.
International processing
Google Docs data is processed on Google’s infrastructure according to your Google account. Our publicly hosted policy pages may be served from global edge locations when you open taixu.app.
Changes to this policy
We may update this policy. The “Last updated” date at the top will change when we do. Continued use after changes means you accept the updated policy.
Contact
Privacy and data questions: [email protected].
You may also use the Chrome Web Store listing’s support or developer contact options for this extension.

墨跡 InkTrace — 隱私政策(繁體中文)
生效日期:2026 年 3 月 28 日 · Chrome 擴充功能項目 ID:fkciapipohelkbfahdacfpckeobdlnao
本政策說明您使用 墨跡 InkTrace 瀏覽器擴充功能(以下稱「本擴充功能」「我們」)時,個人資料與敏感使用者資料的處理方式。
InkTrace 由 太虛幻境 Taixu(taixu.app)發布。
若與您自 Chrome 線上應用程式商店安裝的版本不一致,以該版本為準(該版本不會將分析資料傳送至我們的伺服器)。
本文件說明使用者資料的蒐集、處理、儲存與共享(user data collection, handling, storage, and sharing)。下方標題與英文政策對應一致。
Chrome Web Store — Google API 與 Limited Use(必載聲明)
以下英文句為 Chrome Web Store 對使用 Google 相關資料之固定披露用語,與英文版相同:
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
詳見:Limited Use 政策、
User Data FAQ。
使用者資料蒐集(User data collection)
我們不會為廣告目的蒐集帳號、聯絡人或一般瀏覽紀錄後端資料庫。
為在 Google 文件上提供寫作過程分析,擴充功能會存取:
- Google 文件修訂歷史(目前文件)— 透過您已登入的 Google 工作階段自 Google 伺服器取得,可能包含重播所需的文件內文與編輯中繼資料。
- 文件標題 — 僅供分析介面顯示。
- 技術情境 — 使用 Chrome 擴充功能 API(例如
activeTab、tabs)以判斷您是否於 Google 文件頁面,並開啟分析分頁。
Chrome 線上應用程式商店版本:我們不會將您的文件內容或修訂資料傳送至 Taixu 營運的伺服器進行處理或記錄;分析於您的瀏覽器本機完成。
非商店發佈的「完整版」:可能提供選用伺服器輔助分析;商店版不包含該功能。若您使用該版本,傳輸範圍以產品內說明為準。
使用者資料處理與使用(User data handling)
自 Google 文件取得的資料僅用於:
- 在您的裝置上重播修訂並計算寫作過程指標(例如時間、貼上相關訊號等統計)。
- 依您在擴充功能中的操作,在您的裝置上顯示結果或匯出報告(例如 PDF)。
我們不將該資料用於對您的自動化決策、徵信或僱傭判斷,亦不建立跨站使用者畫像。
使用者資料儲存(User data storage)
擴充功能僅將您的介面語言偏好(中文/英文)存於瀏覽器 localStorage(InkTrace 專用鍵)。我們不在該儲存空間保存文件本文、修訂封包或學生姓名。
使用分析檢視時,與文件相關的資料可能暫存於記憶體;關閉分析分頁或瀏覽器後,就擴充功能而言該工作階段狀態即結束;您的文件仍依 Google 條款保存在 Google 帳戶中。
保存期間:語言偏好將保留至您清除相關網站資料或解除安裝擴充功能為止。
使用者資料共享(User data sharing)
我們不會出售、出租或交易您的個人資料,亦不會向資料仲介分享文件內容或修訂歷史。
Google:修訂資料透過您的 Google 帳戶自 Google 服務取得;Google 所持有之資料適用 Google 的隱私權政策與服務條款。
法律要求:若適用法律或合法程序要求,我們僅在法律強制範圍內揭露必要資訊。
擴充功能權限(Chrome)
activeTab — 偵測您是否正在瀏覽 Google 文件頁面。
tabs — 開啟分析頁面並避免重複分頁。
https://docs.google.com/* 主機權限 — 讀取分析所需之修訂資料。
商店版套件之核心分析功能不會要求連線至 taixu.app。
您的選擇與權利
您可停止使用、自 Chrome 移除擴充功能,或透過瀏覽器設定清除儲存的偏好。商店版不依使用者帳號在我方集中保存使用紀錄,故無另行「刪除帳號」流程。
依您所在地法律,您可能享有查閱、更正或拒絕處理等權利;請透過下方聯絡方式提出,我們將依法回應。
兒童
本擴充功能主要供教育工作者使用,並非以 13 歲以下兒童為對象;我們不會透過本擴充功能故意蒐集兒童個資作商業用途。
跨境與基礎設施
Google 文件資料依您的 Google 帳戶於 Google 基礎設施處理。您瀏覽 taixu.app 上的說明與本政策頁面時,內容可能由全球邊緣節點提供。
政策變更
我們可能更新本政策;更新時將調整上方「最後更新」日期。變更後若您繼續使用,即視為接受更新後之政策。
聯絡方式
隱私與資料相關問題請寄:[email protected]。您亦可透過 Chrome 線上應用程式商店本擴充功能頁面之開發人員/支援管道聯繫。專案說明見 太虛幻境 · 墨跡 InkTrace 專頁。
