This Privacy Policy explains what personal information we collect, how we use it, and your rights in relation to it. By using this Website, you consent to the practices described in this Policy.

This Policy is governed by the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs). Where this Website is accessed from outside Australia, you acknowledge that your information will be handled in accordance with Australian law.

Important Information regarding Health-Related Services
Sheryn Gung offers Martial Arts Therapy (Transformational Self-Defence and Martial Arts or TSDMA), Traditional East Asian Medicine (TEAM) and empowerment coaching as part of an integrated and holistic women's empowerment practice. In the course of providing these services, we may collect sensitive health information with your explicit consent.
Where you engage with our TEAM, TSDMA or other health-related services included Artisanal Shiatsu Treatments, you may be asked to provide health information including medical history, current health conditions, medications, menstrual or hormonal health, and emotional or psychological wellbeing. This information is collected solely for the purpose of tailoring our services to your needs and is treated with the highest degree of care and confidentiality.
We will never collect sensitive health information without your explicit consent, and we will never use it for any purpose other than delivering the services you have requested. You may withdraw your consent to the collection or use of health information at any time by contacting us at hai@sheryngung.com.au.
Health information is subject to the enhanced protections under Australian Privacy Principle 3 and will only be disclosed to third parties where required by law, or in an emergency where your safety or the safety of others is at risk.

We use both session cookies (which expire when you close your browser) and persistent cookies (which remain until deleted) to personalise your experience. Third-party services we use, such as Google Analytics, may also set cookies. You may disable cookies in your browser settings, though some Website functions may not operate correctly as a result.

3. Sensitive Personal Information
Sensitive personal information includes health information, information about your race or ethnic origin, religious beliefs, sexual orientation, criminal record, and similar categories. We treat sensitive information with a higher standard of care.
In the ordinary course of using this Website, you are not required to submit sensitive personal information. However:

4. Health Information — Liability and Scope of Practice
Our services are integrative, holistic and educational in nature. Traditional East Asian Medicine (TEAM) underlies TSDMA as a complementary health modality. Whether you partake in TSDMA or a TEAM service (such as shiatsu), TEAM does not constitute medical diagnosis, treatment, or a substitute for advice from a registered medical practitioner.
Any health information you share with us is used to support the delivery of our services within the scope of self-defence and martial arts, TSDMA methodology, empowerment coaching, and TEAM practice. We are not responsible for decisions you make regarding your health based on information shared through our programs, Website, or sessions without independent medical advice.
By providing health information and participating in our services, you acknowledge:
• You have disclosed any known health conditions that may affect your ability to safely participate in martial arts or self-defence training
• You understand that our services are not a replacement for registered medical, psychological, or psychiatric care
• You accept responsibility for seeking independent professional medical advice where appropriate
In the event of an emergency involving your safety or the safety of others, we reserve the right to disclose relevant information to emergency services or appropriate authorities, without your prior consent.
