Tĩnh Lặng — Terms of Use
Last updated: 2026-08-05
By using Tĩnh Lặng ("the app"), provided by Sakura5, you agree to these terms.
License
We grant you a personal, non-transferable license to use the app on your Apple devices, subject to the App Store Terms of Service.
Subscriptions
The app may offer auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
Price
Version 1.0 of Tĩnh Lặng is free in full: there are no in-app purchases, no subscriptions and no paywall, so the Subscriptions paragraph above does not currently apply to this app.
Not medical advice
Tĩnh Lặng is a relaxation and sleep app. It is not a medical device and does not diagnose, treat or prevent any condition. If you are struggling with your sleep or your mental health, please speak to a qualified professional.
Content
The narration, stories and app content are ours or licensed to us, and are for your personal use inside the app. A video you render in Studio is yours to keep and share.
Acceptable use
Use the app lawfully and don't attempt to disrupt or reverse-engineer it.
Disclaimer
The app is provided "as is" without warranties. AI-generated content may be inaccurate; review it before relying on it.
