睡眠時間計算

問：PowerNap 如何計算我的睡眠時間？

當您設定 20 分鐘的休息時間，應用會先觀察您的心率和運動情況，直到確認您已進入睡眠狀態。這個確認過程通常需要 2-4 分鐘（根據您的年齡組和個人設定）。

重要說明：檢測到您已進入睡眠後，PowerNap 會將確認時間計入總休息時間。例如，如果您設定 20 分鐘休息，確認時間為 3 分鐘，那麼確認睡眠後，系統會倒數 17 分鐘後喚醒您，總休息時間仍為 20 分鐘。

這種計算方式符合睡眠科學研究，因為在確認期間您已經處於淺睡狀態，也在獲得休息的好處。

問：為什麼我的休息時間有時候看起來比設定的短？

您看到的倒計時是剩餘的休息時間，不包括已經過去的確認時間。例如，如果設定 20 分鐘，系統用了 3 分鐘確認您入睡，剩餘計時器會顯示 17 分鐘，但總體休息時間仍然符合您設定的 20 分鐘。

基本功能

問：PowerNap 如何檢測我是否入睡？

PowerNap 使用 Apple Watch 內建的心率感測器和加速度計來監測您的生理狀態變化。當您入睡時，心率通常會下降，並且身體活動會減少。應用程式通過分析這些數據模式來確定您是否已進入睡眠狀態。

問：應用會在什麼情況下喚醒我？

PowerNap 會在以下情況喚醒您：

1. 達到您設定的目標休息時間
2. 檢測到您已自然醒來（如果啟用了自然喚醒功能）
3. 進入深度睡眠狀態超過設定閾值（如果啟用了防止深度睡眠功能）

數據和隱私

問：PowerNap 收集哪些數據？

PowerNap 收集的數據包括：心率數據、運動數據、睡眠時長和質量數據、應用設定和偏好。

所有健康相關數據（心率、睡眠分析等）僅儲存在您的裝置或 Apple Health，絕不傳送至第三方伺服器。

為了偵錯與改進演算法，若您在「設定 → 分享使用資料」啟用匿名遙測，App 會上傳去識別化的使用統計及崩潰診斷（不含任何健康資訊）至 Apple iCloud CloudKit 公用資料庫；您可隨時關閉。

Sleep Time Calculation

Q: How does PowerNap calculate my sleep time?

When you set a 20-minute rest time, the app first monitors your heart rate and motion until it confirms you have entered a sleep state. This confirmation process typically takes 2-4 minutes.

Important: Once sleep is detected, PowerNap includes the confirmation time in the total rest time. For example, if you set a 20-minute nap and it takes 3 minutes to confirm sleep, the system will count down for 17 minutes, resulting in a total rest time of 20 minutes.

Q: Why does my rest time sometimes look shorter than set?

The countdown you see is the remaining rest time, excluding the confirmation time that has already passed.

Basic Functions

Q: How does PowerNap detect if I'm asleep?

PowerNap uses the Apple Watch's built-in heart rate sensor and accelerometer to monitor physiological changes. When you fall asleep, your heart rate typically drops and body movement decreases. The app analyzes these patterns to determine your sleep state.

Data and Privacy

Q: What data does PowerNap collect?

PowerNap collects: Heart rate data, Motion data, Sleep duration/quality, and App settings.

All health-related data is stored ONLY on your device or Apple Health. It is never sent to our servers or third parties.
