21481 Lauenburg, Germany
Email: kontakt@vinayaki-yoga-und-coaching.com

By using the app, you agree to these Terms of Use.

2. Not a Medical Product

VYC Sahitya is a digital wellness offering. It is not a medical device and does not replace medical advice, diagnosis, or treatment.

The content in the app — including breathing exercises, hydration tracking, and accompanying information — is intended to support a healthy lifestyle in the spirit of yoga. It does not constitute a therapeutic measure and is not suitable for diagnosing, treating, or curing any condition.

If you have a medical condition or take medication, please consult your doctor before using the app.

3. Notes on Wellness Claims

Some content in the app refers to effects traditionally attributed to yoga practices within the yoga tradition. These references are to be understood exclusively in the context of yoga tradition and do not constitute medical claims.

Examples of traditional attributions that may be mentioned in the app:

Alternate nostril breathing (Anuloma Viloma) is traditionally practised as a technique to support awareness of the breath and to promote a sense of calm. It is traditionally associated with a balancing effect on the nervous system and general well-being.
Kapalabhati is described in the yoga tradition as a cleansing breathing technique, traditionally associated with an activating and energising effect.

These traditional attributions are not a substitute for medical advice and have not been clinically substantiated within the meaning of applicable advertising or medical device regulations. Vinayaki-Yoga & Coaching does not adopt these statements as advertising claims.

4. Health Suitability and Contraindications

Before using the app, you are responsible for assessing whether the exercises it contains are suitable for you. If in doubt, please consult a doctor or therapist.

Kapalabhati

Kapalabhati is an intensive breathing technique that is not suitable for certain groups of people. Please do not practise Kapalabhati if any of the following apply to you:

Pregnancy
High blood pressure (hypertension)
Heart conditions or cardiac arrhythmias
Epilepsy or a history of seizures
Recent abdominal surgery or hernias
Acute inflammation of the abdominal or thoracic cavity
Dizziness or circulatory problems

Anuloma Viloma (Alternate Nostril Breathing)

Anuloma Viloma is considered a gentle breathing technique. For serious conditions affecting the heart, lungs, or nervous system, it is nevertheless recommended to seek medical advice before use.

General Note

Stop any exercise immediately if you experience dizziness, shortness of breath, pain, or any other discomfort. If symptoms persist, please seek medical attention.

5. Personal Responsibility

Use of the app is voluntary and at your own risk. Vinayaki-Yoga & Coaching accepts no liability for any harm resulting from improper, contraindicated, or excessive use of the app.

You are personally responsible for:

assessing your own health suitability before use
observing the contraindications set out in the app and in these Terms of Use
stopping any exercise if you feel physically unwell
consulting medical professionals regarding any health-related questions

6. Passphrase and Data Loss

The app encrypts all locally stored data using a device-bound key. For transferring data to a new device, an individual recovery passphrase is generated, which you can view in the app settings under “Data & Security”.

Important: Vinayaki-Yoga & Coaching has no access to your data or your passphrase at any time. If the passphrase is lost, recovery of the encrypted data is not possible. Neither Vinayaki-Yoga & Coaching nor any third party can decrypt the data or provide a replacement passphrase.

Please store your passphrase in a safe place — for example, in your device’s password manager.

7. Licence

By making the app available, Vinayaki-Yoga & Coaching grants you a simple, non-transferable, non-exclusive licence for the personal, non-commercial use of the app on your own device.

No exclusive rights are transferred; sublicences are not granted.

Note on AI-assisted content: Individual graphics, illustrations, or other content in the app may have been created in whole or in part using artificial intelligence. Vinayaki-Yoga & Coaching grants usage rights only to the extent that such rights actually exist; no warranty is given regarding protectability or complete freedom from third-party claims.
