隱私權政策

最後更新日期：2026-09-08

「言葉森林 Kotoba Forest」（以下稱「本 App」，Android 套件名稱及 iOS Bundle ID 均為 com.kotobaforest.app）由個人開發者開發與維運。本政策說明本 App 在您使用服務時，會蒐集哪些資訊、如何使用，以及您擁有的權利。

我們蒐集的資訊

• 帳號資訊：首次使用時本 App 會建立匿名帳號（不需提供任何個人資訊）。當您選擇以 Email、Google 帳號或 Sign in with Apple 註冊／登入時，我們會儲存登入服務提供的帳號識別碼及 Email 地址（若您選擇「隱藏我的電子郵件」，可能是 Apple 提供的轉寄地址），用於帳號識別、登入驗證與跨裝置進度備份。
• 學習進度資料：包含您的單字複習紀錄（間隔複習階段、下次複習時間）、連續學習天數、種子與語彙果數量、已擁有與放置的角色、森林狀態等，用於提供個人化的學習功能。
• 購買資訊：若您訂閱 VIP 會員，付款由 Google Play 或 Apple App Store 處理；我們會接收購買憑證、商品方案、訂閱平台與有效期間，用於驗證及維護會員狀態，但不會取得您的信用卡號或完整付款帳戶資訊。
• 假名化使用數據：為了改善產品，我們會記錄有限的 App 互動事件（例如完成一次複習、開始一次測驗等操作類型與發生時間），並以帳號的假名化識別碼（pseudonymous ID）關聯；分析資料也可能包含 App／平台版本，以及訂閱基礎設施提供的最後出現國家層級推定。這不是精準位置，可能受 VPN、模擬器或網路環境影響。這些事件不包含姓名、Email、電話、自由輸入、購買憑證、裝置廣告 ID 或精準位置，僅用於彙總統計、漏斗與功能改善分析。
• 裝置與顯示設定：為了分析相容性與改善產品，我們可能記錄經粗化的螢幕與視窗尺寸、安全區域、系統字級與像素密度級距、裝置品牌與類型、性能級距（裝置年份與記憶體級距）、作業系統主版本、語系／地區／時區，以及是否為實機。這些資料會與假名化帳號識別碼關聯。我們明確不會蒐集裝置廣告 ID、裝置序號、網路位址、使用者自訂裝置名稱、精確型號、儲存空間或輔助使用功能開關。

本 App 不顯示廣告，不使用廣告 SDK，也不會蒐集裝置廣告 ID。

Firebase Analytics 與廣告成效衡量

自 iOS 1.4.8 起，本 App 使用 Google Analytics for Firebase（GA4）了解 App 的整體使用情況，並衡量台灣 iOS 推廣活動是否帶來新的 App 開啟。本 App 內不顯示廣告；Firebase Analytics 是成效分析工具，不是用來在 App 內投放廣告的 SDK。

Firebase Analytics 會為每次 App 安裝自動建立一組隨機的 App Instance ID，並可能自動記錄 App 首次開啟（first_open）、版本更新、工作階段開始、使用時間、作業系統更新、StoreKit 購買或訂閱事件（例如商品編號、名稱、價格、幣別及數量），以及在啟用自動畫面報告時的畫面切換。它也可能從經遮罩處理的 IP 位址推定概略國家／地區，並收集裝置、作業系統、App 版本、Bundle ID 與開發平台等基本技術資訊；不使用 Apple 定位服務取得精準位置。

我們只把 first_open 匯入 Google Ads，作為本次台灣 iOS 推廣活動的新使用者轉換；不把購買、訂閱、學習內容或其他自訂事件設為 Google Ads 轉換、受眾或再行銷條件。我們不會把姓名、Email、電話、帳號 ID、學習答案、自由輸入或購買憑證傳給 Firebase Analytics，也不會使用 IDFA、IDFV、App Tracking Transparency、Google Signals、個人化廣告、跨 App 追蹤、Customer Match 或以聯絡資料進行裝置端轉換衡量。

GA4 的事件層級及使用者層級資料保留期間設定為 2 個月；標準彙總報表不受相同保留期限限制。App Instance ID 不與您的言葉森林帳號或廣告識別碼連結，因此無法用 Email 或帳號 ID 查回這些匿名安裝層級事件；既有事件會依上述保留設定到期。若您對此類資料有疑問，可透過本政策所列 Email 聯絡我們。

我們如何使用這些資訊

• 提供、維護並改善 App 的核心功能（單字學習、間隔複習、森林養成、角色商店等）
• 在您重新開啟 App 或更換裝置時恢復登入狀態與學習進度
• 驗證 VIP 會員訂閱狀態

資料儲存與第三方服務

本 App 使用以下第三方服務來儲存與處理資料：

• Supabase（資料庫與帳號驗證）：儲存您的帳號資訊與學習進度資料
• RevenueCat（訂閱與會員權益管理）：以假名化帳號識別碼處理訂閱狀態與購買驗證資料，並提供最後出現的國家層級推定與 App／平台版本資訊；國家層級推定不是 GPS 或精準位置
• PostHog（產品分析，US Cloud）：接收帳號的假名化識別碼、白名單內的 App 互動事件、必要的 App／平台版本資訊、RevenueCat 提供的最後出現國家層級推定，以及經粗化的裝置與顯示設定，用於漏斗、留存及量測健康分析；不接收 Email、電話、購買憑證、自由輸入、裝置廣告 ID 或精準位置，且已停用 IP 位址儲存
• Google Analytics for Firebase（GA4）：以隨機 App Instance ID 處理 App 生命週期、工作階段、互動、StoreKit 購買／訂閱及概略地區與基本技術資訊，用於彙總分析；僅將 first_open 匯入 Google Ads 衡量台灣 iOS 推廣活動。不使用 IDFA／IDFV、個人化廣告或跨 App 追蹤。
• Google（Google 登入、Google Play 應用程式內購買）：在您選用時處理登入或 Android VIP 訂閱付款
• Apple（Sign in with Apple、App Store 應用程式內購買）：在您選用時處理登入或 iOS VIP 訂閱付款
• 內容傳遞服務：傳遞預錄發音等靜態學習資產；不會向該服務傳送您的帳號資料或學習進度

部分學習資料亦會快取在您的裝置本機，以支援離線學習。我們不會將您的個人資料出售給第三方，亦不會用於與本 App 功能無關的行銷目的。

帳號與資料刪除

您可以隨時要求刪除帳號與相關伺服器端資料，包括 Email、學習進度、遊戲狀態與使用事件。依法令、稅務、防詐或商店交易爭議所必須保留的最少交易驗證紀錄，可能依必要期間保留；付款方式資料由 Google Play 或 Apple App Store 管理，不由本 App 保存。刪除方式有兩種：

1. App 內申請：開啟 App → 「設定」分頁 → 點選最下方「刪除帳號」→ 依畫面指示送出刪除請求。
2. Email 申請：寄信至 kotobaforest.id@gmail.com，主旨註明「刪除帳號請求」並附上您的註冊 Email。

我們會於收到請求後 7 個工作天內完成刪除，包括依同一假名化帳號識別碼刪除 Supabase 與 PostHog 中的相關資料。刪除後所有學習進度無法復原；刪除 App 帳號不會自動取消商店訂閱，VIP 訂閱請另行於 Google Play 或 Apple App Store 的「訂閱」頁面取消，避免持續扣款。

資料保留

您的帳號資訊與學習進度會持續保留，直到您依上述方式要求刪除帳號為止。

Privacy Policy

Last updated: September 8, 2026

“Kotoba Forest” (the “App”; Android package and iOS bundle identifier com.kotobaforest.app) is developed and operated by an independent developer. This policy explains what information the App collects, how it is used, and the choices available to you.

Information We Collect

• Account information: The App creates an anonymous account on first use without asking for personal information. If you choose email, Google, or Sign in with Apple, we store the account identifier and email address supplied by that provider. An Apple private relay address may be used when you choose Hide My Email.
• Learning progress: This includes vocabulary review history, spaced-repetition stage and due time, learning streak, in-app seed and fruit balances, owned and placed characters, and forest state.
• Purchase information: Google Play or the Apple App Store processes VIP subscription payments. We receive a purchase credential, product tier, purchase platform, and entitlement period to verify and maintain VIP access. We do not receive or store your credit card number or full payment account details.
• Pseudonymous usage data: We record limited in-app interaction events, such as starting a quiz or completing a review, together with the event time and a pseudonymous account identifier. Analytics data may also include App/platform versions and a last-seen country-level estimate supplied by our subscription infrastructure. This is not precise location and may be affected by VPNs, emulators, or network conditions. These events do not contain names, email addresses, phone numbers, free-form input, purchase credentials, advertising identifiers, or precise location and are used for aggregate analytics, funnels, and product improvement.
• Device and display settings: To analyze compatibility and improve the product, we may record coarse screen and window dimensions and safe-area insets, system font-size and pixel-density buckets, device brand and type, performance tiers (device-year and memory buckets), operating-system major version, locale/region/time-zone settings, and whether it is a physical device. This data is associated with a pseudonymous account identifier. We do not collect advertising identifiers, device serial numbers, network addresses, user-assigned device names, exact model names, storage capacity, or accessibility toggles.

The App has no advertising, does not use advertising SDKs, and does not collect an advertising identifier.

Firebase Analytics and campaign measurement

Beginning with iOS 1.4.8, the App uses Google Analytics for Firebase (GA4) to understand aggregate App usage and measure whether our Taiwan iOS promotion results in new App opens. The App does not display ads. Firebase Analytics is a measurement service, not an SDK used to serve ads inside the App.

Firebase Analytics automatically creates a random App Instance ID for each installation and may automatically record the first App open (first_open), app updates, session starts, engagement time, operating-system updates, StoreKit purchase or subscription events (such as product ID, product name, price, currency, and quantity), and screen transitions when automatic screen reporting is enabled. It may also derive a general country or region from a masked IP address and collect basic device, operating-system, App-version, bundle-ID, and developer-platform information. It does not use Apple Location Services to obtain precise location.

We import only first_open into Google Ads as the new-user conversion for this Taiwan iOS promotion. We do not use purchases, subscriptions, learning content, or other custom events as Google Ads conversions, audiences, or remarketing conditions. We do not send names, email addresses, phone numbers, account IDs, learning answers, free-form input, or purchase credentials to Firebase Analytics. We do not use IDFA, IDFV, App Tracking Transparency, Google Signals, personalized advertising, cross-app tracking, Customer Match, or contact-information-based on-device conversion measurement.

GA4 event-level and user-level data retention is set to two months. Standard aggregate reports are not subject to the same retention period. The App Instance ID is not linked to your Kotoba Forest account or an advertising identifier, so these anonymous installation-level events cannot be retrieved using an email address or account ID; existing events expire under the retention setting above. Contact us at the email address in this policy if you have questions about this data.

How We Use Information

• Provide, maintain, and improve vocabulary learning, spaced review, forest, and character features
• Restore your sign-in state and progress when you reopen the App or change devices
• Verify and maintain VIP subscription access

Storage and Service Providers

• Supabase: database storage and account authentication
• RevenueCat: subscription and entitlement management using a pseudonymous account identifier, purchase-verification data, and last-seen country-level and App/platform version metadata. The country-level estimate is not GPS or precise location
• PostHog (US Cloud): product analytics using a pseudonymous account identifier, allowlisted App interaction events, necessary App/platform version metadata, and RevenueCat's last-seen country-level estimate, as well as coarse device and display settings, for funnels, retention, and measurement-health analysis. We do not send email addresses, phone numbers, purchase credentials, free-form input, advertising identifiers, or precise location, and IP address storage is disabled
• Google Analytics for Firebase (GA4): processes App lifecycle, session, interaction, StoreKit purchase/subscription, general-region, and basic technical information under a random App Instance ID for aggregate analytics. Only first_open is imported into Google Ads to measure the Taiwan iOS promotion. IDFA, IDFV, personalized advertising, and cross-app tracking are not used.
• Google: optional Google sign-in and Google Play purchases on Android
• Apple: optional Sign in with Apple and App Store purchases on iOS
• Content delivery services: delivery of static learning assets such as prerecorded pronunciation; account details and learning progress are not sent to this service

Some learning data is cached locally for offline use. We do not sell personal information and do not use it for marketing unrelated to the App.

Account and Data Deletion

You may request deletion of your account and associated server data, including email, learning progress, game state, and usage events. Minimum transaction-verification records may be retained where required for legal, tax, fraud-prevention, or store dispute purposes. Payment methods remain with Google Play or Apple and are not stored by the App.

1. In the App: open Settings → Delete Account and follow the on-screen instructions.
2. By email: send a message to kotobaforest.id@gmail.com with the subject “Account deletion request” and include your registered email address.

We complete deletion within seven business days, including deletion of associated Supabase and PostHog data using the same pseudonymous account identifier. Deleted progress cannot be restored. Deleting your Kotoba Forest account does not automatically cancel a store subscription; cancel VIP separately in Google Play or the Apple App Store to avoid future charges.

Retention

Account information and learning progress are retained until you request account deletion as described above.

Children’s Privacy

The App is not specifically directed to children and does not knowingly collect personal information from children under 13.

Changes to This Policy

We may update this policy from time to time. Material changes will be reflected by the updated date at the top of this page.

Firebase Analytics 与广告效果衡量

最后更新日期：2026-09-08

我们收集的信息

• 设备与显示设置：为了分析兼容性并改善产品，我们可能记录经粗化的屏幕与窗口尺寸、安全区域、系统字体大小与像素密度分档、设备品牌与类型、性能分档（设备年份与内存分档）、操作系统主版本、语言／地区／时区，以及是否为真实设备。这些数据会与假名化账号标识符关联。我们明确不会收集设备广告 ID、设备序列号、网络地址、用户自定义设备名称、精确型号、存储空间或辅助功能开关。

数据存储与第三方服务

• PostHog（产品分析，US Cloud）：接收账号的假名化标识符、白名单内的 App 互动事件、必要的 App／平台版本信息、RevenueCat 提供的最后出现国家级别推定，以及经粗化的设备与显示设置，用于漏斗、留存及测量健康分析；不接收 Email、电话、购买凭证、自由输入、设备广告 ID 或精确位置，且已停用 IP 地址存储。

自 iOS 1.4.8 起，本 App 使用 Google Analytics for Firebase（GA4）了解 App 的整体使用情况，并衡量台湾 iOS 推广活动是否带来新的 App 打开。本 App 内不显示广告；Firebase Analytics 是效果分析工具，不是用于在 App 内投放广告的 SDK。

Firebase Analytics 会为每次 App 安装自动建立一个随机的 App Instance ID，并可能自动记录 App 首次打开（first_open）、版本更新、会话开始、使用时长、操作系统更新、StoreKit 购买或订阅事件（例如商品编号、名称、价格、币种及数量），以及在启用自动屏幕报告时的屏幕切换。它也可能根据经过掩码处理的 IP 地址推断大致国家／地区，并收集设备、操作系统、App 版本、Bundle ID 与开发平台等基本技术信息；不会使用 Apple 定位服务取得精确位置。

我们只将 first_open 导入 Google Ads，作为本次台湾 iOS 推广活动的新用户转化；不会将购买、订阅、学习内容或其他自定义事件设为 Google Ads 转化、受众或再营销条件。我们不会将姓名、Email、电话号码、账号 ID、学习答案、自由输入或购买凭证发送给 Firebase Analytics，也不会使用 IDFA、IDFV、App Tracking Transparency、Google Signals、个性化广告、跨 App 跟踪、Customer Match 或使用联系资料进行设备端转化衡量。

GA4 的事件级和用户级数据保留期设为 2 个月；标准汇总报告不受相同保留期限限制。App Instance ID 不会与您的言叶森林账号或广告标识符关联，因此无法通过 Email 或账号 ID 找回这些匿名安装级事件；既有事件将按上述保留设置到期。如对此类数据有疑问，可通过本政策列出的 Email 联系我们。

Google Analytics for Firebase（GA4）：使用随机 App Instance ID 处理 App 生命周期、会话、互动、StoreKit 购买／订阅、大致地区及基本技术信息，用于汇总分析；仅将 first_open 导入 Google Ads 衡量台湾 iOS 推广活动。不使用 IDFA／IDFV、个性化广告或跨 App 跟踪。

Firebase Analytics 및 광고 성과 측정

최종 업데이트: 2026-09-08

수집하는 정보

• 기기 및 디스플레이 설정: 호환성을 분석하고 제품을 개선하기 위해 구간화한 화면 및 창 크기와 안전 영역, 시스템 글꼴 크기 및 픽셀 밀도 구간, 기기 브랜드 및 유형, 성능 등급(기기 연도 구간 및 메모리 구간), 운영체제 주 버전, 언어／지역／시간대 설정, 실제 기기 여부를 기록할 수 있습니다. 이 데이터는 가명화된 계정 식별자와 연결됩니다. 광고 ID, 기기 일련번호, 네트워크 주소, 사용자가 지정한 기기 이름, 정확한 모델명, 저장 공간 또는 접근성 기능 설정은 수집하지 않습니다.

데이터 저장 및 서비스 제공자

• PostHog (US Cloud): 제품 분석을 위해 가명화된 계정 식별자, 허용 목록의 앱 상호작용 이벤트, 필요한 앱／플랫폼 버전 정보, RevenueCat이 제공하는 마지막 확인 국가 수준 추정치, 그리고 구간화한 기기 및 디스플레이 설정을 수신하여 퍼널, 유지율 및 측정 상태 분석에 사용합니다. 이메일, 전화번호, 구매 증빙, 자유 입력 내용, 광고 ID 또는 정확한 위치는 수신하지 않으며 IP 주소 저장은 비활성화되어 있습니다.

iOS 1.4.8부터 본 앱은 전반적인 앱 이용 현황을 파악하고 대만 iOS 프로모션을 통해 새 앱 실행이 발생했는지 측정하기 위해 Google Analytics for Firebase(GA4)를 사용합니다. 본 앱에는 광고가 표시되지 않습니다. Firebase Analytics는 앱 안에 광고를 게재하는 SDK가 아니라 성과 측정 도구입니다.

Firebase Analytics는 설치마다 무작위 App Instance ID를 자동으로 생성하며, 첫 실행(first_open), 앱 업데이트, 세션 시작, 이용 시간, 운영체제 업데이트, StoreKit 구매 또는 구독 이벤트(예: 상품 ID, 상품명, 가격, 통화 및 수량), 자동 화면 보고가 활성화된 경우 화면 전환을 자동으로 기록할 수 있습니다. 또한 마스킹된 IP 주소에서 대략적인 국가／지역을 추정하고 기기, 운영체제, 앱 버전, Bundle ID 및 개발 플랫폼과 같은 기본 기술 정보를 수집할 수 있습니다. Apple 위치 서비스를 사용하여 정확한 위치를 수집하지 않습니다.

Google Ads에는 이번 대만 iOS 프로모션의 신규 사용자 전환으로 first_open만 가져옵니다. 구매, 구독, 학습 내용 또는 기타 맞춤 이벤트를 Google Ads 전환, 잠재고객 또는 리마케팅 조건으로 사용하지 않습니다. 이름, 이메일, 전화번호, 계정 ID, 학습 답변, 자유 입력 내용 또는 구매 증빙을 Firebase Analytics로 보내지 않습니다. IDFA, IDFV, App Tracking Transparency, Google Signals, 개인 맞춤 광고, 앱 간 추적, Customer Match 또는 연락처 정보 기반 온디바이스 전환 측정도 사용하지 않습니다.

GA4의 이벤트 수준 및 사용자 수준 데이터 보관 기간은 2개월로 설정됩니다. 표준 집계 보고서에는 같은 보관 기간이 적용되지 않습니다. App Instance ID는 Kotoba Forest 계정이나 광고 식별자와 연결되지 않으므로 이메일 또는 계정 ID로 이러한 익명 설치 수준 이벤트를 조회할 수 없으며, 기존 이벤트는 위 보관 설정에 따라 만료됩니다. 이 데이터에 관한 문의는 본 정책에 기재된 이메일로 연락해 주세요.

Google Analytics for Firebase(GA4): 무작위 App Instance ID를 사용하여 앱 수명 주기, 세션, 상호작용, StoreKit 구매／구독, 대략적인 지역 및 기본 기술 정보를 집계 분석 목적으로 처리합니다. 대만 iOS 프로모션 측정을 위해 first_open만 Google Ads로 가져옵니다. IDFA／IDFV, 개인 맞춤 광고 및 앱 간 추적은 사용하지 않습니다.

Firebase Analytics và đo lường hiệu quả chiến dịch

Cập nhật lần cuối: 2026-09-08

Thông tin chúng tôi thu thập

• Thiết lập thiết bị và hiển thị: Để phân tích khả năng tương thích và cải thiện sản phẩm, chúng tôi có thể ghi nhận kích thước màn hình, cửa sổ và vùng an toàn ở dạng đã được làm thô; các nhóm cỡ chữ hệ thống và mật độ điểm ảnh; thương hiệu và loại thiết bị; nhóm hiệu năng (nhóm năm của thiết bị và nhóm bộ nhớ); phiên bản chính của hệ điều hành; thiết lập ngôn ngữ／khu vực／múi giờ; và thiết bị có phải là thiết bị thật hay không. Dữ liệu này được liên kết với mã nhận dạng tài khoản đã được giả danh. Chúng tôi không thu thập mã nhận dạng quảng cáo, số sê-ri thiết bị, địa chỉ mạng, tên thiết bị do người dùng đặt, tên mô hình chính xác, dung lượng lưu trữ hoặc các nút bật/tắt trợ năng.

Lưu trữ dữ liệu và nhà cung cấp dịch vụ

• PostHog (US Cloud): nhận mã nhận dạng tài khoản đã được giả danh, các sự kiện tương tác trong Ứng dụng thuộc danh sách cho phép, thông tin cần thiết về phiên bản Ứng dụng／nền tảng, thông tin ước tính quốc gia ở lần xuất hiện gần nhất do RevenueCat cung cấp, cùng các thiết lập thiết bị và hiển thị đã được làm thô, để phân tích phễu, khả năng duy trì người dùng và tình trạng đo lường. Dịch vụ không nhận địa chỉ email, số điện thoại, chứng từ mua hàng, nội dung nhập tự do, mã nhận dạng quảng cáo hoặc vị trí chính xác; chức năng lưu địa chỉ IP đã bị tắt.

Kể từ iOS 1.4.8, Ứng dụng sử dụng Google Analytics for Firebase (GA4) để hiểu tình hình sử dụng tổng thể và đo lường liệu chiến dịch iOS tại Đài Loan có tạo ra lượt mở ứng dụng mới hay không. Ứng dụng không hiển thị quảng cáo. Firebase Analytics là công cụ đo lường, không phải SDK dùng để phân phối quảng cáo bên trong Ứng dụng.

Firebase Analytics tự động tạo một App Instance ID ngẫu nhiên cho mỗi lần cài đặt và có thể tự động ghi nhận lần mở đầu tiên (first_open), cập nhật ứng dụng, bắt đầu phiên, thời gian tương tác, cập nhật hệ điều hành, sự kiện mua hàng hoặc đăng ký qua StoreKit (ví dụ: mã sản phẩm, tên sản phẩm, giá, đơn vị tiền tệ và số lượng), cũng như chuyển màn hình khi tính năng báo cáo màn hình tự động được bật. Dịch vụ cũng có thể suy ra quốc gia／khu vực gần đúng từ địa chỉ IP đã được che và thu thập thông tin kỹ thuật cơ bản như thiết bị, hệ điều hành, phiên bản Ứng dụng, Bundle ID và nền tảng phát triển. Dịch vụ không dùng Apple Location Services để lấy vị trí chính xác.

Chúng tôi chỉ nhập first_open vào Google Ads làm lượt chuyển đổi người dùng mới cho chiến dịch iOS tại Đài Loan này. Chúng tôi không dùng giao dịch mua, đăng ký, nội dung học tập hoặc sự kiện tùy chỉnh khác làm lượt chuyển đổi, đối tượng hay điều kiện tiếp thị lại của Google Ads. Chúng tôi không gửi tên, địa chỉ email, số điện thoại, ID tài khoản, câu trả lời học tập, nội dung nhập tự do hoặc chứng từ mua hàng đến Firebase Analytics. Chúng tôi cũng không sử dụng IDFA, IDFV, App Tracking Transparency, Google Signals, quảng cáo được cá nhân hóa, theo dõi liên ứng dụng, Customer Match hoặc đo lường lượt chuyển đổi trên thiết bị dựa trên thông tin liên hệ.

Dữ liệu cấp sự kiện và cấp người dùng trong GA4 được đặt thời hạn lưu giữ là 2 tháng. Báo cáo tổng hợp tiêu chuẩn không chịu cùng thời hạn lưu giữ này. App Instance ID không được liên kết với tài khoản Kotoba Forest hoặc mã nhận dạng quảng cáo của bạn, vì vậy không thể truy xuất các sự kiện ẩn danh ở cấp cài đặt này bằng email hoặc ID tài khoản; các sự kiện hiện có sẽ hết hạn theo cài đặt lưu giữ nêu trên. Nếu có câu hỏi về dữ liệu này, vui lòng liên hệ qua địa chỉ email trong chính sách.

Google Analytics for Firebase (GA4): xử lý dữ liệu vòng đời ứng dụng, phiên, tương tác, mua hàng／đăng ký qua StoreKit, khu vực gần đúng và thông tin kỹ thuật cơ bản dưới một App Instance ID ngẫu nhiên để phân tích tổng hợp. Chỉ first_open được nhập vào Google Ads để đo lường chiến dịch iOS tại Đài Loan. Không sử dụng IDFA／IDFV, quảng cáo được cá nhân hóa hoặc theo dõi liên ứng dụng.

Firebase Analytics dan pengukuran kampanye

Terakhir diperbarui: 2026-09-08

Informasi yang Kami Kumpulkan

• Pengaturan perangkat dan tampilan: Untuk menganalisis kompatibilitas dan meningkatkan produk, kami dapat mencatat dimensi layar, jendela, dan area aman yang diperkasar; kelompok ukuran font sistem dan kepadatan piksel; merek dan jenis perangkat; tingkat performa (kelompok tahun perangkat dan kelompok memori); versi utama sistem operasi; pengaturan bahasa／wilayah／zona waktu; serta apakah perangkat tersebut merupakan perangkat fisik. Data ini dikaitkan dengan pengenal akun berpseudonim. Kami tidak mengumpulkan pengenal iklan, nomor seri perangkat, alamat jaringan, nama perangkat yang diberikan pengguna, nama model yang tepat, kapasitas penyimpanan, atau tombol fitur aksesibilitas.

Penyimpanan Data dan Penyedia Layanan

• PostHog (US Cloud): menerima pengenal akun berpseudonim, peristiwa interaksi dalam Aplikasi yang masuk daftar izin, informasi versi Aplikasi／platform yang diperlukan, perkiraan negara yang terakhir terlihat dari RevenueCat, serta pengaturan perangkat dan tampilan yang diperkasar, untuk analisis funnel, retensi, dan kesehatan pengukuran. Layanan ini tidak menerima alamat email, nomor telepon, bukti pembelian, masukan bebas, pengenal iklan, atau lokasi presisi, dan penyimpanan alamat IP telah dinonaktifkan.

Mulai iOS 1.4.8, Aplikasi menggunakan Google Analytics for Firebase (GA4) untuk memahami penggunaan Aplikasi secara agregat dan mengukur apakah promosi iOS di Taiwan menghasilkan pembukaan Aplikasi baru. Aplikasi tidak menampilkan iklan. Firebase Analytics adalah layanan pengukuran, bukan SDK untuk menayangkan iklan di dalam Aplikasi.

Firebase Analytics secara otomatis membuat App Instance ID acak untuk setiap instalasi dan dapat otomatis mencatat pembukaan pertama (first_open), pembaruan aplikasi, awal sesi, waktu interaksi, pembaruan sistem operasi, peristiwa pembelian atau langganan melalui StoreKit (seperti ID produk, nama produk, harga, mata uang, dan jumlah), serta perpindahan layar jika pelaporan layar otomatis diaktifkan. Layanan ini juga dapat memperkirakan negara／wilayah umum dari alamat IP yang disamarkan dan mengumpulkan informasi teknis dasar seperti perangkat, sistem operasi, versi Aplikasi, Bundle ID, dan platform pengembangan. Layanan ini tidak menggunakan Apple Location Services untuk memperoleh lokasi presisi.

Kami hanya mengimpor first_open ke Google Ads sebagai konversi pengguna baru untuk promosi iOS di Taiwan ini. Kami tidak menggunakan pembelian, langganan, konten pembelajaran, atau peristiwa kustom lainnya sebagai konversi, audiens, atau ketentuan pemasaran ulang Google Ads. Kami tidak mengirim nama, alamat email, nomor telepon, ID akun, jawaban pembelajaran, masukan bebas, atau bukti pembelian ke Firebase Analytics. Kami juga tidak menggunakan IDFA, IDFV, App Tracking Transparency, Google Signals, iklan yang dipersonalisasi, pelacakan lintas aplikasi, Customer Match, atau pengukuran konversi di perangkat yang memakai informasi kontak.

Retensi data tingkat peristiwa dan tingkat pengguna di GA4 ditetapkan selama 2 bulan. Laporan agregat standar tidak tunduk pada jangka retensi yang sama. App Instance ID tidak ditautkan ke akun Kotoba Forest atau pengenal iklan Anda, sehingga peristiwa anonim tingkat instalasi ini tidak dapat diambil menggunakan email atau ID akun; peristiwa yang sudah ada akan kedaluwarsa sesuai pengaturan retensi di atas. Hubungi kami melalui alamat email dalam kebijakan ini jika Anda memiliki pertanyaan tentang data tersebut.
