How do I scan a document?
Tap Scan Document on the home screen, line up your page, then capture. Adjust the crop corners and tap Use Crop to get a clean PDF page. You can also Import Photo from your library.點首頁「掃描文件」，對準頁面拍照，拖曳四角微調裁切後「使用此裁切」即可；也可「匯入照片」。
Is it really 100% offline?
Yes. ScanTo Pro makes zero network requests. Everything — scanning, OCR text recognition, search, PDF export — runs on your device. It works exactly the same in Airplane Mode.是。本 App 不發出任何網路請求，掃描、OCR、搜尋、匯出全在裝置上；開飛航模式也一樣。
Where are my documents stored?
Privately on your device, inside the app's own storage. They are never uploaded to any server and we never see them. Use Save to Files or Save to Photos if you want a copy elsewhere.只存在你裝置上 App 的私人空間，永不上傳；想另存可用「存到檔案／照片」。
How does searching the text work?
After each scan, on-device OCR reads the text automatically. Just type a word in the search bar and ScanTo Pro finds every document that contains it. Tap View Text to read or copy the recognized text.每次掃描後 OCR 自動辨識文字，搜尋列輸入關鍵字即可找到內含它的文件；「檢視文字」可閱讀/複製。
How do I turn on the Face ID lock?
Open Settings → App Lock and turn it on. The app will then require Face ID or your device passcode each time it opens.到「設定 → App 鎖定」開啟，之後每次開啟 App 都需要 Face ID 或裝置密碼。
How do I export an encrypted (password) PDF?
Open a document, tap the ••• menu and choose Export Encrypted PDF. Set a password — it will be required to open the file. Keep it safe; it cannot be recovered.開啟文件 → 「•••」→「加密匯出 PDF」，設定密碼（無法復原，請保管好）。
