Terms of Service

Effective date: April 9, 2026

1. Eligibility and accounts

You must be at least 18 years old (or the age of majority in your jurisdiction, whichever is greater) to create an account or use the Service. By using the Service, you represent and warrant that you meet this requirement, that the information you provide is accurate and complete, and that you will keep it up to date. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. Notify us immediately at support@greendale.io of any unauthorized use.

2. The Service

The Service is a self-tracking and session-management tool for breathwork practices, including but not limited to BOLT (Body Oxygen Level Test) scores, breath-hold runs, Breathe Light Breathe Right (BLBR) sessions, Wim Hof–style rounds, and altitude / SpO2 training. The Service may also allow practitioners to onboard clients, schedule and manage sessions, sync calendars, and send reminders. Features may be added, modified, or removed at our discretion.

3. User types

The Service is available to two types of Users:

• Individual Users — members of the public who use the Service to log and track their own breathwork practice.
• Practitioners— qualified breathwork instructors, coaches, or health-and-wellness professionals who use the Service to schedule sessions, manage clients, and review client-submitted data. Practitioners are independent of Greendale; we do not employ, supervise, certify, or endorse any Practitioner, and we make no representation or warranty about any Practitioner’s qualifications, training, methods, or fitness for any particular purpose. Any session, advice, treatment, or relationship between a Practitioner and an Individual User is solely between those parties, and Greendale is not a party to it.

4. Acceptable use

You agree that you will not, and will not permit any third party to:

• use the Service for any unlawful, fraudulent, or harmful purpose;
• impersonate any person or entity, or misrepresent your affiliation with a person or entity;
• upload or transmit any content that infringes another’s rights, is defamatory, obscene, or invades privacy;
• attempt to gain unauthorized access to the Service, other accounts, or our systems or networks;
• interfere with, disrupt, or place an unreasonable load on the Service, including by scraping, crawling, or automated data collection except as expressly permitted;
• reverse engineer, decompile, or attempt to derive the source code of the Service except to the extent that applicable law expressly prohibits such a restriction;
• use the Service to provide medical diagnosis, treatment, or advice to any other person.

5. Your content

The Service allows you to submit information about your breathwork practice, including biometric measurements you choose to record (such as breath-hold times, BOLT scores, SpO2 readings, heart-rate values, and notes) (“User Content”). You retain ownership of your User Content. You grant Greendale a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for formatting and display), transmit, and display your User Content solely as needed to operate, provide, secure, and improve the Service, and, where you have requested it, to share that content with a Practitioner you have chosen to connect with. We will handle personal information in accordance with our Privacy Policy.

You are solely responsible for your User Content and for ensuring that you have the right to submit it. You represent and warrant that your User Content does not violate any law or third-party right.

6. Health and safety — assumption of risk

The Service is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. Greendale does not provide medical advice. Information available through the Service is for general informational and personal tracking purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.

Specific risks of breathwork practice. Breathwork practices tracked by the Service — including voluntary hyperventilation, breath retention (apnea), CO₂ tolerance work, hypoxic / altitude simulation training, cold exposure, and intense or prolonged breath-hold protocols — carry real and material risks. These risks include, without limitation: lightheadedness; loss of consciousness (including shallow-water blackout if practiced near or in water); hypoxia and reduced blood-oxygen saturation; cardiac arrhythmia; elevated blood pressure; seizures; falls and injury from loss of consciousness; exacerbation of pre-existing cardiovascular, respiratory, neurological, or psychiatric conditions; pregnancy-related complications; and, in extreme cases, serious injury or death.

Consult a physician first. You should consult a qualified healthcare professional before beginning any breathwork program, particularly if you are pregnant, have a heart condition, high or low blood pressure, a history of stroke, epilepsy or seizure disorder, panic disorder, asthma or other respiratory disease, glaucoma, kidney disease, or any other serious medical condition, or if you take medication that may affect any of the foregoing.

Never practice in or near water and never while driving. Do not perform breath holds, hyperventilation cycles, or hypoxic training in or near water, while operating a vehicle or machinery, while at height, or in any other setting where loss of consciousness could cause harm.

Assumption of risk and release. You knowingly and voluntarily assume all risks associated with your breathwork practice and your use of the Service, whether known or unknown. To the fullest extent permitted by law, you release, waive, and forever discharge Greendale, its members, officers, employees, contractors, agents, and affiliates from any and all claims, demands, damages, liabilities, and causes of action, of any nature, arising out of or related to your breathwork practice, your use of the Service, or any information, recommendation, reminder, or measurement provided through the Service, including any claim arising from the negligence of any released party, to the maximum extent permitted by Ohio law. Stop immediately and seek medical attention if you experience chest pain, severe dizziness, fainting, unusual shortness of breath, or any other warning sign during practice.

SpO2 and other measurements. Any oxygen-saturation, heart-rate, or similar value you enter into the Service comes from a third-party device that Greendale does not manufacture, calibrate, or validate. Such values may be inaccurate. Do not rely on the Service for any clinical or safety-critical decision.

7. Practitioner relationships

If you are an Individual User who books a session with, or shares data with, a Practitioner through the Service, you acknowledge that the Practitioner — not Greendale — is solely responsible for the session, the methods used, any guidance given, and any outcome. Greendale is not a party to the Practitioner-client relationship and does not warrant the safety, effectiveness, or quality of any Practitioner’s services. If you are a Practitioner, you represent and warrant that you are qualified to deliver the services you offer through the Service, that you carry any insurance required by your jurisdiction or profession, and that you will obtain informed consent from your clients as required by applicable law and professional standards. Practitioners are solely responsible for the lawful collection, use, and storage of any client data they handle.

8. Third-party services

The Service may integrate with third-party services such as Google Calendar, Microsoft Outlook, email providers, and authentication providers. Your use of those services is governed by their own terms and privacy policies. Greendale is not responsible for the availability, accuracy, content, or practices of any third-party service.

9. Fees and paid features

Some features of the Service may be offered for a fee. If you purchase a paid feature, the price, billing cycle, and refund policy will be disclosed at the point of purchase and incorporated into these Terms by reference. Unless otherwise stated, all fees are non-refundable, except where required by law. You authorize us (or our payment processor) to charge your chosen payment method for all applicable fees and taxes.

10. Intellectual property

The Service, including all software, designs, text, graphics, logos, and the “Greendale” name and marks, is owned by Greendale or its licensors and is protected by intellectual-property laws. Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal or internal practitioner use. No other rights are granted by implication or otherwise.

11. Termination

You may stop using the Service and close your account at any time by contacting support@greendale.io. We may suspend or terminate your access to the Service at any time, with or without notice, if we believe you have violated these Terms, if required by law, or if continued access poses a risk to Greendale or other Users. Sections that by their nature should survive termination (including Sections 5–6 and 12–17) will survive.

12. Disclaimer of warranties

The Service is provided “as is” and “as available,” without warranty of any kind, express or implied. To the fullest extent permitted by law, Greendale disclaims all warranties, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, and quiet enjoyment. Greendale does not warrant that the Service will be uninterrupted, error-free, secure, or free from loss of data, or that any data, calculation, score, or reminder provided will be accurate or reliable.

13. Limitation of liability

To the fullest extent permitted by law, in no event will Greendale, its members, officers, employees, contractors, or affiliates be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or related to your access to or use of (or inability to access or use) the Service, even if advised of the possibility of such damages. Greendale’s total cumulative liability for all claims arising out of or related to the Service or these Terms will not exceed the greater of (a) the amount you paid Greendale for the Service in the twelve months preceding the event giving rise to the claim, or (b) one hundred US dollars (US$100).

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for certain damages. To the extent that such law applies to you, some or all of the above disclaimers and limitations may not apply, and you may have additional rights.

14. Indemnification

You agree to defend, indemnify, and hold harmless Greendale and its members, officers, employees, contractors, agents, and affiliates from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising from: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any third-party right; (d) your User Content; or (e) if you are a Practitioner, any session you deliver, advice you give, or relationship you form with a client through the Service.

15. Governing law and venue

These Terms and any dispute arising out of or related to them or the Service are governed by the laws of the State of Ohio, without regard to its conflict-of-laws principles. Subject to Section 16, you and Greendale agree that any action or proceeding not subject to arbitration shall be brought exclusively in the state or federal courts located in Ohio, and you and Greendale consent to the personal jurisdiction of those courts.

16. Dispute resolution

We hope to resolve any dispute informally. Before filing a claim, you agree to contact us at support@greendale.io and attempt in good faith to resolve the dispute for at least thirty (30) days. If we cannot resolve the dispute, either party may pursue available legal remedies. You and Greendale agree that any claim must be brought in your or Greendale’s individual capacity and not as a plaintiff or class member in any purported class or representative proceeding, to the fullest extent permitted by law.

17. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we will provide reasonable notice (for example, by email or in-app notice) before it takes effect. Your continued use of the Service after the effective date of an updated version constitutes acceptance of the updated Terms. If you do not agree, you must stop using the Service.

18. Miscellaneous

These Terms, together with any policies referenced in them, are the entire agreement between you and Greendale regarding the Service and supersede any prior agreements. If any provision of these Terms is held to be unenforceable, the remaining provisions will remain in full force and effect. Our failure to enforce any right or provision is not a waiver of that right or provision. You may not assign or transfer these Terms without our prior written consent; we may assign these Terms freely. Nothing in these Terms creates any agency, partnership, or joint venture between you and Greendale.
