## What it does

- **Guided meditation in Vietnamese** — Four narrated sessions — anchoring on the breath, watching your thoughts, listening to your body, and a long one for falling asleep. Written and recorded for this app.
- **Stories for falling asleep** — Four slow bedtime stories, told so you drift off somewhere in the middle. Nobody minds if you never hear the end.
- **Breathe without counting** — Follow the ring instead of counting: pick a rhythm, and the animation and haptics carry the pace for you.
- **Night sounds, all night** — Five ambient spaces — night rain, ocean, night forest, a stream with birds, and a soft meditation pad — that loop for as long as you leave them on.
- **Studio: turn a session into a video** — Render a short video from a session over a gradient or a bundled nature clip, and save it to your own Photos library.
- **Nothing leaves your iPhone** — No account, no sign-in, no server. Your minutes and your streak are written to your own device, and you can erase all of it in Settings.

## How it works

1. **Pick a session** — A meditation, a bedtime story, or just an ambient space to sleep to.
2. **Listen** — Everything plays offline. Layer an ambient bed under any narration if you like.
3. **Keep your streak** — Minutes and days are counted on your device only — yours to see, and yours to delete.

## Privacy

Tĩnh Lặng is built by Sakura5. There is no account, no sign-in, and no Tĩnh Lặng server: the app makes no network requests at all. Every meditation, story, ambient loop and video clip is bundled inside the app, so it works fully offline, in aeroplane mode, forever. We receive nothing from you, because there is no channel through which anything could reach us.

- Nothing. The app collects no data and sends no data anywhere. Its privacy manifest declares no collected data types and no tracking.
- Your listening history — minutes listened and your daily streak — is written to a file inside the app's own storage on your iPhone. It never leaves the device, and Settings → “Xoá toàn bộ dữ liệu” (Erase all data) deletes it.
- Your preferences — language, theme, reminder time, the last track you played — are stored locally in iOS UserDefaults on your device.
- A video you render in Studio — saved to your own Photos library when you ask for it, and nowhere else.
