文件封印區(以下稱「本 App」)將你加入的檔案以 AES-256-GCM 加密後儲存在你的裝置本機。本 App 沒有伺服器,不會上傳、傳送或分析你的檔案、檔名、使用行為或任何個人資料。
本 App 完全離線運作:不需要網路、沒有伺服器。唯一的網路使用是 Apple App Store 的購買驗證,由 iOS 系統處理。本 App 不要求任何背景權限,不使用相機、麥克風、位置、通知、聯絡人、藍牙或廣告識別碼;只在你操作時用到 Face ID、你在系統選取器中挑選的照片,以及使用 App 內建相機時的相機與麥克風。若你開啟 iCloud 加密同步,上傳的只有本機已加密的檔案與索引,Apple 與開發者都無法讀取。
生物辨識由 iOS 系統處理,本 App 只會得知驗證成功或失敗,不會取得任何生物特徵資料。
「從照片加入」使用系統選取器,本 App 只能存取你選取的項目。「存回照片」需要你授權新增權限。本 App 不會讀取或修改你未選取的照片。
本 App 的隱私等級是「本機加密、零上傳、開發者不可讀」。它無法防護已越獄或遭入侵的裝置、系統漏洞、解鎖期間的記憶體讀取、截圖錄影,以及你自行分享出去的解密副本。詳見服務條款。
App 內購買(一次性買斷)由 Apple App Store 處理。本 App 只透過 Apple 提供的 StoreKit 得知購買是否有效,不會取得你的付款資訊。
本 App 不使用任何分析、廣告或追蹤 SDK。
在 App 內「設定 → 銷毀所有內容」或刪除本 App,即可刪除所有資料。PIN 連續錯誤 5 次也會自動銷毀。刪除後無法還原。

Private Docs Vault ("the App") stores the files you add on your device only, encrypted with AES-256-GCM. The App has no server and never uploads, transmits, or analyzes your files, file names, usage, or any personal data.
The App works entirely offline: no network, no server. The only network use is Apple App Store purchase verification, handled by iOS. The App requests no background permissions and does not use the camera, microphone, location, notifications, contacts, Bluetooth, or advertising identifiers; it only uses Face ID, the photos you pick in the system picker, and the camera and microphone when you use the built-in camera. If you enable iCloud encrypted sync, only locally encrypted files and the encrypted index are uploaded; neither Apple nor the developer can read them.
Biometrics are handled by iOS. The App only learns whether authentication succeeded.
"Add from Photos" uses the system picker, so the App can only access the items you select. "Save to Photos" requires add-only permission.
The App's privacy level is "on-device encryption, zero upload, unreadable by the developer". It cannot protect against jailbroken or compromised devices, OS vulnerabilities, memory access while unlocked, screenshots or recordings, or decrypted copies you share. See the Terms of Use.
The one-time in-app purchase is processed by the Apple App Store. The App only learns whether the purchase is active via StoreKit and never sees payment details.
The App contains no analytics, advertising, or tracking SDKs.
Use Settings → Destroy all content, or delete the App. Five consecutive wrong PIN entries also destroy all content. Deletion cannot be undone.
