Privacy
Light Sleep（轻眠）is a free app by Yugakhan. This page explains what the app and this website do with information. Effective 16 February 2023; updated 23 September 2026 for the current iOS build.
On your device
Favorites, listening history, mix presets, heal streaks, sleep journal notes, stats, alarm settings, and language choice stay on the device. Light Sleep does not ask you to create an account.
Health (optional)
If you turn it on, the app may write an Apple Health “In Bed” marker while you use bedtime tools. It does not read sleep stages or other Health data.
Purchases
Unlocking the full library is a one-time in-app purchase handled by Apple or Google. Yugakhan does not receive your payment card number.
Ads
The free tier may show Google AdMob interstitial ads at a low chance after certain taps, and optional rewarded ads if you choose to watch them for temporary unlock. The app does not request App Tracking Transparency permission to track you across other companies’ apps. Unlocking removes ads.
