不蒐集個人資料的 App
向量財管 VectraFin、懂我筆記本 KnowMeNote、ObjectifyAR、英語救星、師記、Melody Journal、Notelyra 與我的台灣觀光地圖不會透過開發者營運的伺服器向使用者蒐集個人資料。
向量財管 VectraFin
向量財管 VectraFin 會在使用者裝置上處理使用者自行輸入的帳戶名稱、交易金額、Hashtags、備註、日期、週期帳設定、統計查詢條件、資產或負債紀錄，以及由這些資料產生的圖表、趨勢與明細。這些資料用於記帳、資產清點、負債追蹤、週期帳預測、Hashtag 階層分析與視覺化功能。
開發者不會透過自己的伺服器收集、上傳或檢視使用者在 VectraFin 中建立的財務資料。資料預設保存在使用者裝置上；若使用者選擇本機備份、iCloud 快照或 iCloud 同步，相關資料會由使用者裝置或 Apple iCloud 服務依使用者的系統設定與 Apple 的隱私權實務處理。
VectraFin 不要求註冊帳號，也不會建立開發者營運的外部伺服器帳號。若使用者刪除 App、刪除帳戶、關閉同步或管理備份，資料保留與刪除結果會依 App 操作、裝置設定與 iCloud 設定而定。
懂我筆記本 KnowMeNote
懂我筆記本 KnowMeNote 會在使用者裝置上處理使用者自行輸入、貼上、聽寫或匯入的筆記文字、草稿內容、逐字稿文字、文字修正、復原動作、常用字詞、替換紀錄、偏好線索與統計資料。這些資料用於多則筆記、一鍵複製、本機學習、自動替換、復原、統計面板與重置學習資料等功能。
開發者不會透過自己的伺服器收集、上傳或檢視使用者在 KnowMeNote 中建立的筆記內容或學習資料。學習運算在使用者裝置上進行，不需要開發者伺服器。
若使用者啟用 iCloud 同步，筆記與學習線索會透過使用者的 iCloud 帳號在 iPhone 和 iPad 間同步，並依 Apple 的 iCloud 設定與隱私權實務處理。原始輸入歷史不會作為額外紀錄同步。使用者可以關閉同步或在 App 內重置學習資料；重置學習資料會清除已學會的偏好、替換紀錄與字詞統計，但不會刪除筆記內容。
ObjectifyAR
ObjectifyAR 會在使用者裝置上處理使用者拍攝或匯入的物件影像、相機畫面、3D 模型、USDZ 檔案、物件名稱、描述、註記、hashtags、策展文字、展示分類與收藏庫資料。這些資料用於物件掃描、3D 模型建立、AR 拍照、Mac 上的 RealityKit Photogrammetry 重建、收藏整理，以及 Apple Vision Pro 上的沉浸式展示。
開發者不會透過自己的伺服器收集、上傳或檢視使用者在 ObjectifyAR 中建立的照片、拍攝資料、3D 模型、收藏庫或策展文字。資料預設保存在使用者裝置上；若使用者啟用 iCloud 同步或透過 iCloud 共享收藏庫，相關資料會由 Apple iCloud 服務依使用者的系統設定與 Apple 的隱私權實務處理。
策展人文字功能會根據使用者提供的物件名稱、描述與 hashtags 整理展示說明。這些內容的處理方式取決於使用者裝置、系統功能與所啟用的 Apple 服務；開發者不會建立開發者營運的外部帳號來保存這些內容。
我的台灣觀光地圖
我的台灣觀光地圖會在使用者授權後讀取相簿中照片的 GPS 座標與拍攝時間，用於判斷景點是否已造訪、分組旅程訪次、建立景點相簿、顯示成就統計與整理計劃清單。照片內容、座標比對結果、旅行回憶與日誌內容以裝置端處理為核心，開發者不會透過自己的伺服器收集或上傳使用者的照片、相簿內容或 GPS 足跡。
使用者可使用 iOS 內建的 Writing Tools 協助撰寫旅遊日誌，也可透過系統 Share Sheet 分享相簿與日誌。這些功能由 Apple 或使用者選擇的分享目的地處理，請同時參考 Apple 與相關第三方服務的隱私實務。
App 使用政府或公開來源的觀光資料來呈現景點資訊與分類。這些公開資料不包含使用者個人資料，且資料內容可能由來源單位更新。
Notelyra
Notelyra 會在裝置上處理課程錄音、產生的筆記、樂器選擇、標題、時間標籤與關鍵字編輯，用於錄音、轉錄、練習回顧與音樂探索功能。開發者不會向使用者蒐集這些內容。
當使用者開啟 Apple Music 推薦或串流播放至 HomePod 時，相關功能由 Apple 提供，並依 Apple 的隱私權實務、帳號設定與媒體服務條款處理。
台北菜價與廣告
台北菜價使用 Google 廣告服務。App 本身並非為直接蒐集使用者個人資料而設計，但 Google 可能依其隱私權政策處理裝置或廣告相關資訊以投放廣告。

Privacy Policy
Last updated: May 5, 2026
This Privacy Policy applies to apps and services published by Yu-Hsiang Chang, including VectraFin, KnowMeNote, ObjectifyAR, MyTaiwanTourMap, 英語救星, 台北菜價, 師記, Melody Journal, and Notelyra, unless a specific app provides a separate privacy notice.
Sticker Vault and 注音故事 have their own privacy policies linked from their app pages.
Apps Without Personal Data Collection
VectraFin, KnowMeNote, ObjectifyAR, 英語救星, 師記, Melody Journal, Notelyra, and MyTaiwanTourMap do not collect personal data from users through developer-operated servers.
VectraFin
VectraFin processes account names, transaction amounts, hashtags, notes, dates, recurring-entry settings, statistics query conditions, asset or liability records, and the charts, trends, and details generated from that information on the user's device. This information is used for bookkeeping, asset review, liability tracking, recurring-entry forecasting, hierarchical hashtag analysis, and visualization features.
Yu-Hsiang Chang does not collect, upload, or view financial records created by users in VectraFin through developer-operated servers. Data is stored on the user's device by default. If the user chooses local backups, iCloud snapshots, or iCloud sync, the relevant data is handled by the user's device or Apple's iCloud services according to the user's system settings and Apple's privacy practices.
VectraFin does not require account registration and does not create developer-operated server accounts. If a user deletes the app, deletes an account, turns off sync, or manages backups, data retention and deletion results depend on the app action, device settings, and iCloud settings.
KnowMeNote
KnowMeNote processes notes, drafts, pasted text, dictated text, transcript-style text, text corrections, undo actions, frequent terms, replacement history, preference signals, and statistics on the user's device. This information is used for multiple notes, one-tap copy, on-device learning, automatic replacement, undo, the statistics panel, and learning-data reset features.
Yu-Hsiang Chang does not collect, upload, or view notes or learning data created by users in KnowMeNote through developer-operated servers. Learning runs on the user's device and does not require a developer-operated server.
If the user enables iCloud sync, notes and learning signals may sync between iPhone and iPad through the user's iCloud account and are handled according to Apple's iCloud settings and privacy practices. Raw input history is not synced as an additional separate record. Users can turn off sync or reset learning data in the app. Resetting learning data clears learned preferences, replacement history, and term statistics, but does not delete note content.
ObjectifyAR
ObjectifyAR processes object photos, camera views, 3D models, USDZ files, object names, descriptions, notes, hashtags, curator text, exhibition categories, and collection library data on the user's device. This information is used for object scanning, 3D model creation, AR photography, RealityKit Photogrammetry reconstruction on Mac, collection organization, and immersive display on Apple Vision Pro.
Yu-Hsiang Chang does not collect, upload, or view photos, capture data, 3D models, collection libraries, or curator text created by users in ObjectifyAR through developer-operated servers. Data is stored on the user's device by default. If the user enables iCloud sync or shares the collection library through iCloud, the relevant data is handled by Apple's iCloud services according to the user's system settings and Apple's privacy practices.
The curator text feature creates exhibition-style descriptions based on object names, descriptions, and hashtags provided by the user. How this content is processed depends on the user's device, system features, and enabled Apple services; the developer does not create developer-operated external accounts to store this content.
MyTaiwanTourMap
After the user grants permission, MyTaiwanTourMap reads GPS coordinates and capture dates from photos in the user's photo library to determine visited attractions, group trip visits, build place albums, show achievement statistics, and manage planning lists. Photo content, coordinate matching results, travel memories, and journal content are designed around on-device processing. Yu-Hsiang Chang does not collect or upload users' photos, album content, or GPS travel history through developer-operated servers.
Users may use Apple's built-in Writing Tools to help draft travel journals and may share albums or journal content through the system Share Sheet. These features are handled by Apple or by the sharing destination selected by the user, so Apple's and relevant third-party privacy practices may also apply.
The app uses government or public tourism data to display attraction information and categories. This public data does not contain user personal data and may be updated by the source providers.
Notelyra
Notelyra processes lesson recordings, generated notes, instrument selections, titles, time tags, and keyword edits on device. These items are used to provide recording, transcription, practice review, and music discovery features. Yu-Hsiang Chang does not collect this content from users.
When users open Apple Music recommendations or stream playback to HomePod, those features are provided by Apple and handled under Apple privacy practices, account settings, and media service terms.
台北菜價 and Advertising
台北菜價 uses Google advertising services. While the app itself is not intended to collect personal data directly from users, Google may process device-related or advertising-related information under its own systems and privacy policy in order to deliver ads.
