PDF 神器
Privacy policy
Transparency before connection
This policy explains how the Android app PDF God, published by CB Studio, handles information. The website you are reading loads only local static assets and does not include an analytics or advertising runtime.
PDF God is a PDF reading and note application published by CB Studio. This policy covers information handled by the app and support requests sent to dio071512@gmail.com. It does not replace the separate policies of Google, Firebase, AdMob, RevenueCat, or other services you choose to use. Network traffic uses HTTPS / TLS where the platform and provider support it, and the app requests least privilege scopes for optional services.
PDF God may keep a local library index, document paths and metadata, thumbnails, reading progress, annotations, handwriting geometry, tags, favorite marks, workspace state, app settings, consent choices, feature counters, and diagnostic state needed to operate the app.
You choose which PDFs the app can access. Original files and imported, unlocked, or exported local copies remain in the storage locations you select and are user-controlled. The app may create app-managed or temporary copies when a feature requires them, such as importing an external file or saving an unlocked copy. Do not email sensitive PDF contents, passwords, or secret keys to support.
Google Drive sync is opt-in. It starts only after you turn on the connection, sign in to Google, and authorize the Drive application-data scope. PDF God uses the hidden private appDataFolder for sync data such as filename and path metadata, reading progress, highlight and note records, favorite marks, handwriting geometry, tags, and related sync records. PDF God is designed to sync these records, not the original PDF file content, under a least privilege Drive scope.
Google processes sign-in, authorization, identifiers, network data, and the stored app data under its policies and third-party retention rules. You can disconnect Drive in the app. You can also manage hidden app data through Google Drive. Learn about the Google Drive appDataFolder.
AI features require a user action and an in-app consent step. When you use one, PDF text extracted for that action, selected text, questions, prompts, and related context are sent through Firebase AI to a Google Gemini model under Google's paid services terms. Submitted content is not used to improve or train Google products. Google may process and retain content for a limited period for abuse detection, security, and legal obligations. The response returns to the app. PDF God may keep your consent choice and local usage counters on the device. You can revoke AI consent later in Settings → Sync settings.
Review Firebase AI Logic, Firebase privacy information, and the Google Privacy Policy before sending sensitive material.
PDF God uses Firebase App Check with Play Integrity on Android to help confirm that AI and other protected calls come from a genuine app instance. App Check relies on Firebase Installations (including a Firebase installation ID / FID) and short-lived App Check token values. Tokens are used to attest requests, not to build advertising profiles. Retention and deletion of installation identifiers and tokens follow Firebase and Google platform limits; uninstalling the app or clearing app data removes local copies, while provider-side retention remains subject to Google's service terms.
Eligible free users may be shown banner, interstitial, or rewarded ads delivered by AdMob. Ad requests and ad interactions may involve IP address, advertising or app identifiers, device and app information, approximate location inferred from network data, consent signals, diagnostics, impressions, and clicks. Whether ads are personalized depends on region, device settings, consent, and Google's controls.
To review or change advertising consent where required, open Settings → Sync settings → Ad privacy options, which reopens the Google UMP privacy options form when available for your region. Google describes advertising identifiers and controls in AdMob privacy guidance.
Paid plans and in-app purchases are offered through Google Play. PDF God uses RevenueCat to retrieve offerings, complete the purchase flow, restore purchases, and determine subscription or entitlement status. These services may process product, price, currency, transaction and subscription identifiers, purchase status, app user or installation identifiers, country or store information, and technical diagnostics. PDF God does not receive your full payment card number from Google Play.
Support requests about purchases may include the minimum identifiers needed to locate a transaction. Payment and transaction records may remain with Google Play, RevenueCat, payment systems, and CB Studio as required for billing, entitlement restoration, tax, accounting, security, fraud prevention, dispute handling, and law. A support request does not guarantee automatic deletion of those platform records. Purchase records are also governed by the Google Privacy Policy and the RevenueCat Privacy Policy.
The public legal pages are served by Firebase Hosting. Standard hosting access log data (such as IP address, user agent, request path, and timestamps) may be processed by Google to operate, secure, and troubleshoot the site under Google's retention limits. This static site does not run an analytics or advertising SDK in the browser.
Information may be disclosed to service providers named above, when you direct the app to use them, or when required to protect users, enforce rights, prevent fraud, or comply with law.
For access, correction, deletion, or privacy questions, contact dio071512@gmail.com. Do not email passwords, secret keys, payment card details, or PDF contents.
This policy may be updated when the app, providers, or legal requirements change. A revised date will be posted on this page.
連線前先說清楚
本政策說明由 CB Studio 發行的 Android 應用程式 PDF 神器如何處理資訊。你正在閱讀的網站只載入本地靜態資產，不包含分析或廣告執行碼。
PDF 神器是由 CB Studio 發行的 PDF 閱讀與筆記應用程式。 本政策涵蓋 App 處理的資訊，以及寄到 dio071512@gmail.com 的支援請求。 Google、Firebase、AdMob、RevenueCat 或你選擇使用的其他服務，仍適用各自政策。 網路傳輸在平台與供應商支援時使用 HTTPS / TLS，選用服務則採 最小權限 範圍。
PDF 神器可能在本機保留文件庫索引、檔案路徑與中繼資料、縮圖、閱讀進度、 標註、手寫幾何、標籤、收藏標記、工作區狀態、App 設定、同意選擇、功能用量計數， 以及維持 App 運作所需的診斷狀態。
由你選擇 App 可以存取的 PDF。原始檔案以及匯入、解鎖或匯出的本機副本，仍位於你選擇的儲存位置， 並由使用者控制。在匯入外部檔案、另存解鎖副本等功能需要時，App 可能建立由 App 管理或暫存的副本。 請勿透過電子郵件傳送敏感 PDF 內容、密碼或秘密金鑰。
Google Drive 同步需由你選擇啟用（opt-in）。只有在你 開啟連線、登入 Google 並授權 Drive 應用程式資料範圍後才會開始。PDF 神器使用 隱藏且私密的 appDataFolder 儲存同步資料，例如檔名與路徑中繼資料、 閱讀進度、標註與筆記、收藏、手寫幾何、標籤與相關同步紀錄。這項設計在 最小權限 Drive 範圍下同步的是上述紀錄，不是原始 PDF 檔案內容。
Google 會依其政策與第三方保留規則處理登入、授權、識別碼、網路資料及儲存的 App 資料。 你可以在 App 中中斷 Drive 連線，也可透過 Google Drive 管理隱藏的應用程式資料。請參閱 Google Drive appDataFolder 說明。
AI 功能需要你的操作與 App 內同意。使用時，該次操作所擷取的 PDF 文字、選取文字、問題、提示與相關脈絡，會在 Google 付費服務條款下，透過 Firebase AI 傳送給 Google Gemini 模型。提交內容 不會用於改進或訓練 Google 產品。Google 可能為 濫用偵測、安全與法律義務在有限期間內處理或保留內容。 回應會送回 App。PDF 神器可能在裝置上保留同意選擇與本機用量計數。你可稍後在 「設定」→「同步設定」撤銷 AI 同意。
傳送敏感內容前，請閱讀 Firebase AI Logic、 Firebase 隱私資訊 與 Google 隱私權政策。
PDF 神器使用 Firebase App Check，並在 Android 搭配 Play Integrity，協助確認 AI 與其他受保護呼叫來自真實 App 實例。 App Check 依賴 Firebase Installations（含 Firebase installation ID / FID） 與短效 App Check token。Token 用於證明請求，不用於建立廣告設定檔。 安裝識別碼與 token 的保留與刪除遵循 Firebase 與 Google 平台限制；解除安裝或清除 App 資料會移除本機副本， 供應商端保留仍受 Google 服務條款約束。
符合條件的免費使用者可能看到由 AdMob 提供的橫幅、 插頁或獎勵式廣告。廣告請求與互動可能涉及 IP 位址、廣告或 App 識別碼、裝置與 App 資訊、由網路資料推定的大致位置、同意訊號、診斷、曝光與點擊。是否使用個人化 廣告會受所在地區、裝置設定、同意狀態與 Google 控制項影響。
若需檢視或變更廣告同意，請開啟「設定」→ 「同步設定」→「廣告隱私選項」， 在適用地區重新開啟 Google UMP 隱私選項表單。Google 在 AdMob 隱私說明中介紹廣告識別碼與控制方式。
付費方案與 App 內購買由 Google Play 提供。PDF 神器使用 RevenueCat 取得方案、完成購買流程、恢復購買，以及判斷 訂閱或使用權狀態。這些服務可能處理商品、價格、幣別、交易與訂閱識別碼、購買狀態、 App 使用者或安裝識別碼、國家／商店資訊與技術診斷。PDF 神器不會從 Google Play 收到你的完整付款卡號。
與購買有關的支援請求可能包含定位交易所需的最少識別資訊。付款與交易紀錄可能由 Google Play、RevenueCat、付款系統與 CB Studio 依計費、使用權恢復、稅務、會計、安全、 防詐、爭議處理及法律要求保留。支援請求不保證自動刪除這些平台紀錄。購買紀錄也適用 Google 隱私權政策 與 RevenueCat 隱私權政策。
公開法律頁面由 Firebase Hosting 提供。標準 Hosting 存取紀錄（例如 IP 位址、使用者代理、請求路徑與時間戳） 可能由 Google 依其保留限制處理，以營運、保護並排除網站問題。此靜態網站不會在瀏覽器執行分析或廣告 SDK。
當你指示 App 使用上述服務，或為保護使用者、行使權利、防止詐欺及遵守法律所需時， 資訊可能會提供給相關服務供應商或依法揭露。
如需存取、更正、刪除或詢問隱私問題，請聯絡 dio071512@gmail.com。請勿透過電子郵件 傳送密碼、秘密金鑰、付款卡資料或 PDF 內容。
當 App、服務供應商或法律要求變更時，本政策可能更新，並在本頁標示新的修訂日期。
