Terms of use

Updated 22 August 2026

These terms govern your use of the Sylph app. By installing or using the app, you agree to them.

The app

Sylph is a wellness and relaxation app: a breathing pacer. It is provided as-is. It is not a medical device, is not a substitute for professional care, and makes no claim to treat, reduce, relieve, manage or diagnose anxiety, stress disorders, insomnia, panic, blood pressure, heart rate or any other health condition. If you have a health concern, please talk to a qualified health professional.

Licence

You are granted a personal, non-exclusive, non-transferable licence to use the app on devices you own or control, for personal, non-commercial use. You may not resell, redistribute, or reverse-engineer the app except where such restriction is prohibited by law.

Purchases

Sylph Pro is an optional one-time purchase made through the store you installed the app from: Google Play or the App Store, priced in your local currency. It unlocks the additional techniques, the custom pattern builder, every visual, haptic and audio theme, the longer session lengths and casting. There is no subscription and nothing to cancel. The purchase is processed by that store under its own terms and is restored on any device signed into the same store account, with Play's normal restore mechanism for a Google account and Restore Purchases for an Apple Account. Refunds follow that store's policy: Google Play's refund policy or Apple's.

Sensible use

Paced breathing can leave you light-headed, particularly at first. Sit or lie down, breathe only as deeply as is comfortable, and stop if a pattern feels uncomfortable or leaves you unwell. Gentler techniques suit most people better than extended holds. Don't follow a session while driving, cycling, swimming, in a bath, or in any other situation that needs your attention. If you are pregnant, or you have a heart, breathing or anxiety condition, or you faint easily, talk to a health professional before using breathing exercises.

No warranty

The app is provided “as is”, without warranties of any kind. We do our best to keep it stable and pleasant to use, but we cannot guarantee it will be uninterrupted or error-free. Nothing in these terms excludes, restricts or modifies any guarantee, right or remedy you have under the Australian Consumer Law or any other consumer protection law that cannot lawfully be excluded.

Limitation of liability

To the maximum extent permitted by law, Zone7 Studios Pty Ltd is not liable for any indirect, incidental or consequential loss arising from your use of the app. Where our liability cannot lawfully be excluded, it is limited to resupplying the app or paying the cost of having it resupplied.

Governing law

These terms are governed by the laws of Australia. Nothing here affects any consumer rights you have under the law of the country you live in.
