「Word Game World」（以下稱「本 App」，開發者 HaoGameStudio）是一款收錄「單字披薩」「釣魚單字」「單字英雄」三款小遊戲、以間隔複習（SRS）學習韓文／英文／日文單字的學習遊戲。本政策說明本 App 蒐集、使用與分享哪些資料。你可以在不登入的情況下遊玩；此時本 App 只會為這台裝置產生一組隨機匿名 ID來備份你的遊戲存檔，不會取得 Email 或任何能識別你本人的資訊。只有在你主動登入、使用好友或內購等功能時，才會涉及進一步的資料處理。
本 App 的核心遊玩可離線、在本機進行。以下資料僅在你使用對應功能時才會蒐集（第一列為首次開啟即自動進行的匿名備份）：
| 資料類型 | 何時蒐集 | 用途 |
|---|---|---|
| 隨機匿名裝置 ID 與遊戲存檔（單字熟練度、金幣、寵物、簽到、設定等） | 首次開啟 App 時自動建立；之後在遊玩期間定期備份 | 備份這台裝置的進度；ID 為 App 隨機產生，不含任何個資、不與其他來源的資料交叉比對 |
| Email 帳號 | 你選擇以 Email／Google／Apple 登入時 | 建立帳號、跨裝置同步、帳號復原；登入後上述匿名備份會直接綁定到你的帳號 |
| 暱稱與好友碼（uid） | 使用社交／好友功能時 | 讓好友與排行榜辨識你；好友清單儲存於伺服器 |
| 購買憑證（去識別化交易資訊） | 進行內購時 | 發放金幣／VIP 權益；不含付款卡號 |
| 廣告識別碼（IDFA／廣告 ID） | 你觀看獎勵廣告且（iOS）同意追蹤時 | 由 Google AdMob 用於投放與衡量廣告 |
| 使用與診斷資料（概略，例如錯誤紀錄、功能使用情形） | 使用線上功能時可能蒐集 | 維持服務穩定與改善體驗 |
若你從不登入、不看廣告、不內購、不使用社交功能，伺服器上與你有關的資料就只有那組隨機匿名 ID 與遊戲存檔，不含 Email 或任何可識別你本人的資訊。這組 ID 的憑證只存在你的裝置上：刪除 App 會連同它一起清除，備份便無法再取回——若要在重裝或換機後找回進度，請登入帳號。
你可以選擇以 Email、Google 或 Apple 登入。登入後，我們會在伺服器（Cloudflare）儲存你的 Email、學習進度與遊戲存檔，以便在你的不同裝置間同步。未登入仍可遊玩，此時我們只以前述的隨機匿名 ID 備份存檔，不會取得 Email 或任何身分資訊；你登入後，這組匿名帳號會直接升級綁定到你的帳號，進度不會遺失。你可隨時於 App 內登出，或於 App 內自助刪除帳號（見第 7 節）。我們的後端由 Cloudflare 提供，其伺服器與資料中心分布於全球；使用雲端功能時，你的資料可能被傳輸至你所在國家／地區以外處理，此類傳輸適用 Cloudflare 的標準契約條款與 Cloudflare 隱私權政策。
本 App 使用 Google AdMob 顯示「選擇性」獎勵廣告——只有在你主動點擊「看廣告」按鈕時才會播放，遊戲不會強制你觀看。AdMob 可能存取你裝置的廣告識別碼（IDFA／廣告 ID）以投放與衡量廣告。
在 iOS 上，本 App 會依 Apple 的「App 追蹤透明度（ATT）」機制詢問你是否允許追蹤；即使你拒絕，仍可正常觀看獎勵廣告，也不影響其他遊戲功能——此時廣告不會使用你的廣告識別碼進行跨 App／跨網站追蹤。若你位於歐洲經濟區、英國或瑞士，本 App 另會依 Google 使用者訊息平台（UMP）徵詢廣告同意；未取得同意時一律只請求非個人化廣告，你也可隨時在「設定 → 廣告隱私設定」中修改。AdMob 對資料的處理另適用 Google 隱私權政策。
付費項目（金幣包、VIP 訂閱）一律透過 Apple App Store 內購機制，並由 RevenueCat 協助處理交易與權益發放。我們不會收到、也不會儲存你的信用卡或付款卡號；僅會收到去識別化的購買憑證，用以發放對應的金幣或 VIP 權益。付款資訊由 Apple 依其隱私政策處理。VIP 為自動續訂訂閱，價格、週期與取消方式會在購買前清楚揭露，並可隨時於 App Store 帳號設定取消。
當你使用社交功能時，你設定的暱稱與好友碼（uid）會對你的好友與排行榜可見，你的好友清單會儲存於伺服器以維持好友關係。你可以選擇不使用社交功能；暱稱可自行設定，請勿填入真實姓名或其他敏感個資。
為了知道哪些單字大家最常答錯（用來改善題目與解釋）以及遊戲內金幣的整體進出（用來平衡難度與獎勵），本 App 會回傳匿名的彙總計數。
這些統計不含任何可識別你的資訊：伺服器上只有「某個單字在某種題型被答對／答錯的累計次數」與「某一天某個來源進出多少金幣」，沒有帳號代碼、沒有時間序列、也無法還原成任何一位玩家的遊玩紀錄。你的個別答題內容不會被單獨儲存。
本 App 的單字發音採用事先製作、隨 App 一起下載的離線音檔播放；少數情況會使用你裝置內建的系統語音合成（Text-to-Speech）。兩者皆在你的裝置本機運作，不會傳送你的任何資料。
本 App 使用下列第三方服務，其各自的隱私政策適用於其所處理的資料：
本 App 為一般年齡層的語言學習遊戲，並非刻意面向 13 歲以下兒童設計。由於本 App 含可選的資料蒐集（登入、雲端同步、社交）與第三方廣告，不適合在無監護人同意下供兒童使用。我們依循美國《兒童線上隱私保護法》(COPPA)，不會在知情情況下、於未取得可驗證家長同意前蒐集 13 歲以下兒童的個人資料；若你認為孩童在未經同意下提供了個人資料，請來信，我們將儘速刪除。建議家長使用裝置的家長監護與內購限制功能。
若功能或資料處理方式有變動，我們會更新本政策並在此頁標示新的更新日期。重大變更會在 App 內或本頁適當提示。
本 App 為獨立的語言學習工具。JLPT、TOPIK、TOEIC 及其他考試名稱為各自主辦單位的商標，僅用於說明本 App 涵蓋的字彙範圍；本 App 與上述任何檢定主辦單位均無隸屬、合作或授權關係，亦不保證任何考試成績或結果。

Word Game World (the "App", developed by HaoGameStudio) is a vocabulary-learning game (Korean / English / Japanese) for Traditional-Chinese speakers, featuring three mini-games — Word Pizza, Word Fishing and Word Hero — using spaced repetition (SRS). You can play without signing in; in that case the App only generates a random anonymous ID for this device to back up your game save, and never obtains your Email or anything that could identify you. Further data processing only occurs when you choose to sign in or use features such as friends or in-app purchases.
Core gameplay runs offline and on-device. The following data is collected only when you use the relevant feature (the first row is the anonymous backup that starts automatically on first launch):
| Data type | When collected | Purpose |
|---|---|---|
| Random anonymous device ID & game save (word mastery, coins, pets, check-ins, settings, etc.) | Created automatically on first launch; backed up periodically while you play | Back up this device's progress; the ID is randomly generated by the App, contains no personal data and is not cross-referenced with any other source |
| Email / account | When you sign in with Email / Google / Apple | Create account, cross-device sync, account recovery; after sign-in the anonymous backup above is linked to your account |
| Nickname & friend code (uid) | When you use social / friends features | Identify you to friends and leaderboards; friend list stored on server |
| Purchase receipts (de-identified transaction info) | When you make a purchase | Grant coins / VIP; no card numbers collected |
| Advertising identifier (IDFA / Ad ID) | When you watch a rewarded ad and (on iOS) allow tracking | Used by Google AdMob to serve and measure ads |
| Usage & diagnostics (coarse, e.g. error logs, feature usage) | May be collected when using online features | Keep the service reliable and improve the experience |
If you never sign in, never watch ads, never purchase, and never use social features, the only data about you on our server is that random anonymous ID and the game save — no Email and nothing that identifies you. The credential for that ID lives only on your device: deleting the App removes it too and the backup can no longer be retrieved — sign in if you want to recover progress after reinstalling or switching devices.
You may optionally sign in with Email, Google, or Apple. After signing in, we store your Email, learning progress, and game saves on our server (Cloudflare) so they can sync across your devices. You can still play without signing in, in which case we only back up your save under the random anonymous ID described above and obtain no Email or identity information; when you later sign in, that anonymous account is upgraded and linked to your account, so no progress is lost. You can sign out anytime in the App, or delete your account in-app (see Section 7). Our backend is provided by Cloudflare, whose servers and data centers are located globally; when you use cloud features, your data may be transferred and processed outside your country/region, subject to Cloudflare's Standard Contractual Clauses and Cloudflare Privacy Policy.
The App uses Google AdMob to show optional rewarded ads — they only play when you tap a "Watch ad" button; the game never forces you to watch. AdMob may access your device's advertising identifier (IDFA / Ad ID) to serve and measure ads.
On iOS, the App asks for your permission via Apple's App Tracking Transparency (ATT). If you decline, you can still watch rewarded ads and other features are unaffected — in that case ads do not use your advertising identifier for cross-app or cross-site tracking. If you are in the EEA, the UK or Switzerland, the App additionally asks for ad consent through Google's User Messaging Platform (UMP); without consent the App requests non-personalized ads only, and you can change your choice at any time under Settings → Ad privacy settings. AdMob's handling of data is also subject to the Google Privacy Policy.
Paid items (coin packs, VIP subscription) are handled entirely through Apple App Store in-app purchase, with RevenueCat assisting transaction processing and entitlement delivery. We never receive or store your credit card or payment card number; we only receive de-identified purchase receipts used to grant the corresponding coins or VIP. Payment details are handled by Apple under its privacy policy. VIP is an auto-renewing subscription; price, period, and how to cancel are clearly disclosed before purchase, and can be canceled anytime in your App Store account settings.
When you use social features, the nickname you set and your friend code (uid) are visible to your friends and on leaderboards, and your friend list is stored on the server to maintain friendships. Using social features is optional; choose a nickname that does not include your real name or other sensitive personal information.
To learn which words players most often get wrong (so we can improve the questions and explanations) and how in-game coins flow overall (so we can balance difficulty and rewards), the app reports anonymous aggregate counts.
These statistics contain nothing that identifies you: the server stores only "how many times a given word was answered correctly or incorrectly in a given question type" and "how many coins entered or left on a given day from a given source". There is no account identifier, no timeline, and no way to reconstruct any individual player's activity. Your individual answers are never stored separately.
Word pronunciation uses pre-generated offline audio bundled with the App; in some cases your device's built-in Text-to-Speech is used. Both run on-device and transmit none of your data.
The App uses the following third-party services, whose own privacy policies apply to the data they process:
The App is a general-audience language-learning game and is not directed at children under 13. Because it includes optional data collection (login, cloud sync, social) and third-party advertising, it is not intended for use by children without parental consent. In line with the U.S. Children's Online Privacy Protection Act (COPPA), we do not knowingly collect personal data from children under 13 without verifiable parental consent; if you believe a child has provided personal data without consent, please contact us and we will delete it promptly. Parents are encouraged to use device parental controls and purchase restrictions.
If features or data practices change, we will update this policy and the date above. Material changes will be highlighted in-app or on this page as appropriate.
The App is an independent language-learning tool. JLPT, TOPIK, TOEIC and other exam names are trademarks of their respective organizations, referenced only to describe vocabulary scope; the App is not affiliated with, endorsed by, or licensed by any of these organizations, and does not guarantee any exam results.
