Do I need to sign in? No. The app requires no account or sign-in — just open and start.
怎麼開始？ 在「物件」分頁新增一棟房子，設定房間與各房的分電表，定期抄表填入度數；計費期間到了就按「結算」，App 會自動算出每房應繳金額（房內度數＋公用電平均分攤 × 每度單價），並產生每一房的 PDF 帳單。
How do I start? In the Properties tab, add a building, set up its rooms and sub-meters, and record meter readings periodically. When the billing period ends, tap "Settle" — the app computes each room's amount (room usage + shared electricity × unit price) and generates a PDF bill per room.
Is my data synced? Where is it kept? Yes. Data syncs across your own devices through your personal iCloud and lives in your own iCloud account. The developer cannot see it, and there are no developer servers.
How do I remove ads? Unlock "Pro" in Settings (a one-time in-app purchase) to remove the banner and interstitial ads. Pro also includes future premium features.
如何還原購買？ 前往「設定」，點擊「回復購買」，使用原先購買時的同一組 Apple ID 即可恢復 Pro。
How do I restore my purchase? Go to Settings and tap "Restore Purchases," using the same Apple ID as the original purchase to restore Pro.
Can multiple people share the bookkeeping? Yes. Use Settings ▸ Export All Data to pack everything (including photos) into a single .rntefee file and share it; the recipient opens it to merge-import. Great for taking turns.
電表照片存在哪裡？ 存在您的裝置與您自己的 iCloud，不會上傳到開發者伺服器。
Where are meter photos stored? On your device and in your own iCloud — never uploaded to developer servers.
會提醒我結算嗎？ 會。可在各物件的「物件設定」開啟「每月結算日提醒」，這是您裝置上的本機通知。
Will it remind me to settle? Yes. Enable the monthly settlement-day reminder in each property's settings — it's a local notification on your device.
Does the app track me? On first launch, the app asks for App Tracking Transparency (ATT). If you decline, ads switch to non-personalized; app functionality is unaffected.
