中文

我們不收集任何個人資料

WordBook（字裡行間）沒有我們自己的帳號、沒有分析工具、沒有廣告、沒有第三方追蹤 SDK。我們沒有伺服器會接收你的資料。

App 有兩項選用功能會用到你既有的 Apple 帳號：Game Center 與 iCloud。兩者都是存進你自己的 Apple 帳號，不會經過我們。詳見下方「Game Center」與「iCloud 同步」兩節。

你的書留在你的裝置上

你匯入的 EPUB 檔案與切段後的書本全文，只寫在你自己裝置的 App 沙箱內。這些內容不會離開你的裝置，也不會被同步到任何地方。唯一的例外是朗讀：按下朗讀時，那一段文字會送到微軟的語音服務換回聲音 —— 詳見下方「網路連線」第 3 點。

閱讀進度、統計數字、成就與收藏的金句同樣寫在裝置上，另外會存一份到你自己的 iCloud 帳號，讓你換裝置時能接著讀 —— 詳見下方「iCloud 同步」。無論哪一種，都不會被備份到我們這裡，我們也無法讀取。

刪除 App 即刪除這台裝置上的全部資料。你也可以在「設定 → 關於 → 清除所有資料」中隨時自行清空，那會同時清掉 iCloud 上的副本。

網路連線

App 會連網的情況有三種，都是你主動觸發的：

1. 在「書庫」中瀏覽或下載公共領域書籍時，會向 Gutendex（gutendex.com）請求書目，並向 Project Gutenberg（www.gutenberg.org）下載 EPUB 檔案。
2. 購買或還原「完整版」、或贊助開發者時，會向 Apple 或 Google 的付款服務發出請求。
3. 按下朗讀時，若這台裝置連著網路，會把當下要朗讀的那一段文字送到微軟的語音服務（speech.platform.bing.com，也就是 Edge 瀏覽器「大聲朗讀」用的同一個服務），換回一段語音來播放。挑選朗讀語音的畫面也會向同一個服務要一份可用聲音的清單，那份請求只問清單，不含任何書本內容。送出的只有那一段文字本身：不含書名、不含你書架上有什麼、不含你讀到哪裡，也不含任何識別你的資料。沒有網路、或微軟沒有那個語言的聲音時，改用你裝置自己的語音，什麼都不會送出。

這些請求只包含取得檔案或完成交易所需的一般資訊，不包含任何識別你的資料，也不包含你書架上有什麼、你玩到哪裡。除此之外，App 在完全離線的狀態下可以正常使用（包含已購買的完整版：購買狀態記在你的裝置上，開 App 不需要等網路）。

購買

「完整版」為一次性的 App 內購買，由 Apple（App Store）或 Google（Play 商店）處理，不是訂閱。付款資訊由 Apple／Google 收取與保管，我們不會看到你的付款方式或帳單資料，也沒有伺服器會記錄你買了什麼。我們從平台收到的只有「這台裝置是否已購買」這一個是非值，並把它寫在你自己的裝置上。

贊助開發者

「設定 → 關於 → 贊助開發者」裡的三個項目是自願的、可重複的 App 內購買，同樣由 Apple 或 Google 處理。贊助不會解鎖任何功能，也不會改變 App 的行為。我們在你的裝置上只記下「贊助過幾次」這個數字，用途只有一個：讓 App 說一次謝謝，而不是再問你一次。這個數字不會離開你的裝置，也不會被上傳到任何地方。

Game Center

如果你的裝置已登入 Game Center，App 會把兩類數字送到你的 Apple 帳號下：

1. 成就 —— 你已達成的十四個成就，就是「統計與成就」畫面上那些。
2. 排行榜 —— 三個數字：累計復原段落數、每日挑戰最長連續天數、最長連對次數。

送出去的只有這些數字。你書架上有哪些書、你在讀哪一本、讀到哪裡、匯入了什麼檔案，一律不會送出。

這些紀錄由 Apple 保管、受 Apple 的隱私政策規範，並且屬於你的 Apple 帳號而不是這個 App。你的 Game Center 顯示名稱在排行榜上對其他玩家是可見的 —— 那是排行榜的用途 —— 但那個名稱由你在系統設定裡決定，我們讀不到你的真實姓名或 Apple ID。

這是選用的。在系統「設定 → Game Center」裡把它關掉，App 就完全不會送出任何東西，其餘功能一切照常。App 從不向 Game Center 讀回資料，只單向送出。

「清除所有資料」清掉的是這台裝置上的紀錄。已經記在 Game Center 裡的成就與排行榜成績留在你的 Apple 帳號下 —— 那是你的，不是我們的，我們也沒有權限刪除它。要清掉 Apple 那邊的紀錄，請在系統「設定 → Game Center」裡處理。

iCloud 同步

如果你的裝置已登入 iCloud，App 會把下面這些存到你自己的 iCloud 帳號下，好讓你換一台裝置、或在兩台裝置上輪流讀的時候，進度能接得上：

1. 閱讀進度 —— 每本書在每種讀法下已經復原了哪些段落，以及各段的最佳成績。
2. 統計與成就 —— 累計數字、每日挑戰的連續天數、已達成的成就。
3. 收藏的金句 —— 你自己存下來的句子，以及它出自哪本書。
4. 未完成的那一局 —— 你上次讀到一半的盤面，好讓「繼續」有東西可以打開。

不會同步的：你匯入的 EPUB 原檔與書本全文。那些留在裝置上，不會離開它。

用的是 Apple 的 iCloud 鍵值儲存（NSUbiquitousKeyValueStore）。這些內容存在你的 iCloud 帳號裡，由 Apple 保管、受 Apple 的隱私政策規範。這中間沒有我們的伺服器，我們也讀不到任何一個字。

這是選用的。在系統「設定 →〔你的名字〕→ iCloud」裡把 WordBook 關掉，或是根本沒登入 iCloud，App 就只會寫在本機，其餘功能一切照常。

「清除所有資料」會同時清掉這台裝置上的紀錄與 iCloud 上的那份副本。要提醒的是：如果你另一台裝置上還留著同樣的進度，它下次同步時會把自己那一份重新放回 iCloud —— 那台裝置上的閱讀並沒有被清除，也不該由這裡替它決定。

兒童

App 不收集資料，因此也不會收集兒童的資料。App 內沒有廣告，也沒有使用者之間的通訊功能。Game Center 排行榜上只會出現顯示名稱與數字，沒有任何聊天或訊息功能；如果不希望孩子出現在排行榜上，請在「螢幕使用時間」或系統「設定 → Game Center」中關閉。

變更

若這份政策有變更，會更新本頁最上方的日期，並隨 App 更新一併發佈。

We collect nothing

WordBook has no accounts of ours, no analytics, no advertising and no third-party tracking SDKs. There is no server of ours that receives your data.

Two optional features use an account you already have — Apple’s Game Center and iCloud. Both keep things under your own Apple account; neither goes anywhere near us. See the Game Center and iCloud sync sections below.

Your books stay on your device

The EPUB files you import and the text of your books are written only to the app's own sandbox on your device. None of it leaves the device, and none of it is synced anywhere. Reading aloud is the one exception: the passage being read is sent to Microsoft's speech service to be turned into a voice — see point 3 under Network access below.

Reading progress, statistics, achievements and saved lines are written to the device too, and a copy is kept under your own iCloud account so that reading picks up where you left off on another device — see iCloud sync below. Either way, none of it is backed up to us, and we cannot read it.

Deleting the app deletes everything on this device. You can also clear it yourself at any time under Settings → About → Clear all data, which clears the copy in iCloud along with it.

Network access

The app reaches the network in three situations, all of which you start:

1. When you browse or download public-domain books in the Library, it requests the catalogue from Gutendex (gutendex.com) and the EPUB files themselves from Project Gutenberg (www.gutenberg.org).
2. When you buy or restore the full version, or sponsor the developer, it talks to Apple's or Google's payment service.
3. When you have a passage read aloud and this device is online, it sends the passage being read to Microsoft's speech service (speech.platform.bing.com — the same one Edge's own “read aloud” uses) and plays back the voice it returns. The screen where you choose a voice asks the same service for its list of voices; that request carries no book text. Only the passage itself is sent: not the book's title, not what is on your shelf, not how far you have read, and nothing that identifies you. With no network, or in a language Microsoft has no voice for, your device's own synthesiser reads it and nothing is sent.

Those requests carry only the ordinary information needed to fetch a file or complete a transaction — nothing that identifies you, and nothing about what is on your shelf or how far you have read. Everything else works fully offline, including the full version once bought: what you own is recorded on your own device, so opening the app never waits on a network.

Purchases

The full version is a one-time in-app purchase — not a subscription — handled by Apple on the App Store and by Google on Play. Payment details are collected and held by them; we never see your payment method or billing information, and there is no server of ours that records what you bought. All we receive from the platform is a single yes/no — whether this device has purchased — which is then stored on your device.

Sponsoring the developer

The three items under Settings → About → Sponsor the developer are voluntary, repeatable in-app purchases, handled by Apple and Google in the same way. Sponsoring unlocks nothing and changes nothing about how the app behaves. The only thing recorded on your device is how many times you have sponsored, for one purpose: so the app can say thank you rather than ask you again. That number never leaves your device and is not uploaded anywhere.

Game Center

If your device is signed in to Game Center, the app posts two kinds of number to your Apple account:

1. Achievements — the fourteen you have earned, the same ones shown on the statistics screen.
2. Leaderboards — three figures: passages restored in total, your longest run of daily challenges, and your longest run of correct answers.

That is all that is sent. Which books are on your shelf, which one you are reading, how far you have read and what you have imported are never sent.

Those records are held by Apple, governed by Apple’s privacy policy, and belong to your Apple account rather than to this app. Your Game Center display name is visible to other players on the leaderboards — that is what a leaderboard is for — but that name is one you choose in your system settings, and we cannot read your real name or your Apple ID.

This is optional. Turn Game Center off under Settings → Game Center on your device and the app posts nothing at all; everything else works exactly as before. The app only ever sends to Game Center; it never reads anything back.

Clear all data clears what is on this device. Achievements and leaderboard scores already recorded in Game Center stay under your Apple account — they are yours, not ours, and we have no way to delete them. To clear those, use Settings → Game Center on your device.

iCloud sync

If your device is signed in to iCloud, the app keeps the following under your own iCloud account, so that reading picks up where you left off when you change devices or read on two of them:

1. Reading progress — which passages each way of reading has restored in each book, and the best score for each.
2. Statistics and achievements — the running totals, the daily-challenge streak, and the achievements earned.
3. Saved lines — the passages you kept, and which book each came from.
4. The interrupted board — the puzzle you were halfway through, so that continue has something to open.

What is not synced: the EPUB files you imported and the text of your books. Those stay on the device they were added to.

This uses Apple's iCloud key-value store (NSUbiquitousKeyValueStore). It lives in your iCloud account, held by Apple and governed by Apple's privacy policy. There is no server of ours in between, and we cannot read a word of it.

This is optional. Turn WordBook off under Settings → [your name] → iCloud, or simply do not sign in to iCloud, and the app writes only to this device; everything else works exactly as before.

Clear all data clears both what is on this device and your copy in iCloud. One thing worth knowing: if another of your devices still holds the same reading, it will put its own copy back into iCloud the next time it syncs — that device was not cleared, and this one does not get to decide for it.

Children

The app collects no data, and therefore collects no data from children. There is no advertising and no communication between users. A Game Center leaderboard shows display names and numbers and nothing else — there is no chat and no messaging. If you would rather a child did not appear on one, turn Game Center off under Screen Time or Settings → Game Center.

Changes

If this policy changes, the date at the top of this page is updated and the change ships with an app update.
