## What Tĩnh Lặng is

A Vietnamese meditation and sleep app for iPhone: four guided meditations, four bedtime stories, five all-night ambient spaces, a guided breathing rhythm, and a Studio that renders a short video from a session. The interface is available in Vietnamese and English (Settings → language); the narration is in Vietnamese. Everything is bundled in the app, so it works with no internet connection and no account.

## Frequently asked

- **Does it cost anything?** No. Version 1.0 is free in full, with no in-app purchases, no subscription and no paywall.
- **Do I need an account or the internet?** Neither. There is no sign-in of any kind, and all audio and video is bundled — the app works in aeroplane mode.
- **How do I delete my data?** Settings → “Xoá toàn bộ dữ liệu” erases your listening history and streak. Deleting the app removes everything it stored as well.
- **Can I turn the daily reminder off?** Yes, in Settings. It is a local notification, at most one a day, and switching it off removes it.
- **Audio stops when I lock the screen.** Playback is meant to continue with the screen off. If it stops, check that Low Power Mode or a Focus setting isn't suspending it, and email us with your device and iOS version.
- **Saving a Studio video failed.** The app needs add-only permission for Photos. Check iPhone Settings → Tĩnh Lặng → Photos and allow “Add Photos Only”.
- **Is this medical advice?** No. Tĩnh Lặng is for relaxation only and is not a substitute for professional care.

## Common questions

- **Restore a purchase:** open the app's paywall and tap “Restore Purchases”.
- **Manage a subscription:** iPhone Settings → your name → Subscriptions.
- **Bug or feedback:** email us with your device model and iOS version.
