Legal
The terms governing your use of Ultropic.
1. Acceptance of These Terms
These Terms of Service (these “Terms”) form a binding agreement between you and Ultropic (“Ultropic”, “we”, “us”, or “our”) governing your access to and use of the Ultropic web application and related services (the “Service”). Ultropic is operated by Ultropic (UEN 53524950X), with a registered address at 60 PAYA LEBAR ROAD, #06-28, PAYA LEBAR SQUARE, Singapore 409051.
By creating an account, starting a free trial, or otherwise accessing or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy. If you do not agree, you must not use the Service.
These Terms take effect on 14 June, 2026.
2. Description of the Service
Ultropic is an AI-assisted running coach delivered as a web application. The Service builds personalised, periodised training plans and provides coaching guidance, with a particular orientation toward runners in Singapore and Southeast Asia.
To provide its features, the Service may:
• Connect to your Intervals.icu account (via OAuth) to read your training and health data and to write planned workouts back to your Intervals.icu calendar.
• Use your postal code, geocoded into approximate coordinates, to suggest nearby running routes and provide local weather.
• Send your training context and health-related metrics to a third-party AI provider (OpenAI) to generate training plans and coaching responses. Per OpenAI’s API policy, data submitted through its API is not used to train its models. This and other data sharing are described in our Privacy Policy.
The Service is provided on an “as available” basis and may change over time. Further detail on the data we collect and the third parties we rely on is set out in our Privacy Policy.
3. Eligibility and Age
You must be at least 18 years old to use the Service, or older if the law of your country requires a higher age for you to consent to the processing of your personal data. By using the Service, you represent that you meet this requirement and that you are able to enter into a binding contract.
If you use the Service on behalf of another person or organisation, you represent that you are authorised to accept these Terms for them.
4. Accounts and Security
To use the Service you must create an account. You can sign up and sign in using an email address and password, or by using “Sign in with Google” or “Sign in with Apple”. Authentication is handled using the Better Auth library, and your session is maintained through a first-party cookie.
You agree to:
• Provide accurate and current account information and keep it up to date.
• Keep your login credentials confidential and not share your account with others.
• Be responsible for all activity that occurs under your account.
• Notify us promptly at privacy@ultropic.com if you suspect any unauthorised use of your account.
We are not liable for any loss arising from unauthorised use of your account where you have not safeguarded your credentials.
5. Subscription, Free Trial, and Payment
Free trial
New users may start a 14-day free trial. No credit card is required to begin the trial. During the trial you have access to the Service as described above. We may change or discontinue trial offers at any time.
Paid subscription
After the free trial, continued use of the Service requires a paid subscription priced at SGD 20 per month (the “Subscription”), unless we state otherwise. All prices are in Singapore Dollars. The price is inclusive of Singapore GST.
Payment processing
Payments are processed by Stripe. You will provide your payment details directly through Stripe, and your use of Stripe’s payment services is subject to Stripe’s own terms. Ultropic does not store your full card number; that information is handled by Stripe.
Auto-renewal and cancellation
The Subscription renews automatically each month and your payment method will be charged at the start of each billing period until you cancel. You may cancel at any time through the Service or by contacting us at privacy@ultropic.com. When you cancel, your Subscription remains active until the end of the current paid period, after which it will not renew.
Refunds
Except where a refund is required by applicable law, payments are non-refundable and we do not provide refunds or credits for partial billing periods, unused time, or periods during which you did not use the Service.
Price changes
We may change the Subscription price. Where we do, we will give you reasonable advance notice of 7 days, and any change will apply to billing periods beginning after the notice takes effect. If you do not agree to a price change, you may cancel before it takes effect.
6. Health and Safety — Important: Not Medical Advice
Please read this section carefully.
The training plans, coaching, recommendations, and any other content provided through the Service are for general informational and educational purposes only. They are NOT medical advice, and they are not a substitute for professional medical advice, diagnosis, or treatment. Coaching content is generated with the assistance of AI and may be incorrect, incomplete, or unsuitable for your individual circumstances; you must use your own judgement before acting on it.
• Consult a physician or other qualified healthcare professional before beginning any exercise programme, before significantly increasing your training load, and if you have any condition that may be affected by exercise.
• Running and physical training carry inherent physical risks, including the risk of injury, illness, or, in rare cases, serious harm. You voluntarily assume all such risks when you act on plans or coaching provided through the Service.
• Ultropic is NOT a medical device. It does not diagnose, treat, cure, monitor, or prevent any medical condition, and it should not be relied on for any such purpose.
• Always listen to your body. Stop exercising and seek medical attention if you experience pain, dizziness, shortness of breath, chest discomfort, or any other warning sign.
You are solely responsible for deciding whether and how to follow any plan or coaching provided through the Service. To the fullest extent permitted by law, you use the Service’s fitness and coaching content at your own risk.
7. Acceptable Use
You agree not to:
• Use the Service in any way that breaks applicable law or infringes the rights of others.
• Access, tamper with, or use non-public areas of the Service, our systems, or our service providers’ systems.
• Attempt to probe, scan, or test the vulnerability of the Service, or breach any security or authentication measures.
• Interfere with or disrupt the integrity or performance of the Service, including by introducing malware or by sending excessive automated requests.
• Reverse engineer, decompile, or attempt to extract the source code of the Service, except to the extent this restriction is prohibited by law.
• Use the Service to build or train a competing product, or to scrape or harvest data from the Service.
• Submit data that you do not have the right to submit, or impersonate any person or entity.
We may suspend or terminate access if we reasonably believe you have breached this section.
8. Intellectual Property
Our rights
The Service, including the application, its software, design, text, graphics, and all related intellectual property, is owned by Ultropic or its licensors and is protected by law. Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service for your personal, non-commercial use. We reserve all rights not expressly granted.
Your data and content
You retain ownership of the data and content you provide to or create within the Service, including your account details, your postal code, your training and health data, your training plans, and your coach chat messages (“Your Content”).
You grant Ultropic a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, process, and display Your Content solely as needed to operate and provide the Service to you. This includes sending relevant training context and health-related metrics to the third-party services described in Section 9 and in our Privacy Policy so that the Service can function. This licence ends when Your Content is deleted, except where retention is required by law or as described in our Privacy Policy.
You are responsible for Your Content and confirm that you have the necessary rights to provide it.
9. Third-Party Services
The Service relies on third-party services (sub-processors) to function. These currently include Intervals.icu, OpenAI, Stripe, Resend, Google, Apple, OneMap, Open-Meteo, Render, and Cloudflare. How each is used, and what data is shared with them, is described in our Privacy Policy.
In particular:
• Intervals.icu is the source of your training and health data. You connect your Intervals.icu account via OAuth, and Ultropic both reads from and writes planned workouts to that account. You are responsible for maintaining your own Intervals.icu account and for your relationship with, and the terms of, Intervals.icu and any other third-party account you connect or use (including your Google or Apple sign-in account).
• OpenAI processes your training context and health-related metrics to generate plans and coaching. Per OpenAI’s API policy, data submitted through its API is not used to train its models.
• You may disconnect Intervals.icu at any time. Doing so will limit features that depend on that data.
Third-party services are governed by their own terms and privacy policies, and we are not responsible for their acts, omissions, availability, or content. Your use of those services is at your own risk.
10. Disclaimers of Warranties
To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express, implied, or statutory. We disclaim all implied warranties, including any warranties of merchantability, fitness for a particular purpose, title, and non-infringement.
We do not warrant that the Service will be uninterrupted, timely, secure, or error-free, that any defects will be corrected, or that any plans, coaching, recommendations, data, or other output will be accurate, complete, reliable, or suitable for your circumstances. AI-generated content may be incorrect or incomplete, and you should use your own judgement before relying on it.
Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.
11. Limitation of Liability
To the fullest extent permitted by law:
• Ultropic and its founder, contractors, and suppliers will not 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 relating to your use of (or inability to use) the Service.
• Without limiting the health and safety provisions in Section 6, and to the extent permitted by law, we are not liable for any personal injury, illness, or harm resulting from exercise or training undertaken in connection with the Service.
• Our total aggregate liability arising out of or relating to the Service or these Terms will not exceed the greater of (a) the total amounts you paid to us for the Service in the 6 months before the event giving rise to the claim, or (b) SGD 100.
Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence where such liability cannot lawfully be excluded, or for fraud. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
12. Indemnity
To the extent permitted by law, you agree to indemnify and hold harmless Ultropic and its founder, contractors, and suppliers from and against any claims, liabilities, damages, losses, and reasonable expenses (including legal fees) arising out of or related to: (a) your use of the Service; (b) Your Content; (c) your breach of these Terms; or (d) your violation of any law or the rights of any third party.
13. Termination
You may stop using the Service at any time and may delete your account through the Service or by contacting us at privacy@ultropic.com. When you delete your account it is closed immediately and your personal data is removed; as described in our Privacy Policy, we keep a minimal record for up to 6 months for fraud prevention and then permanently delete it. If you sign up again within 6 months of deleting your account, you will not be eligible for a new free trial.
We may suspend or terminate your access to the Service, with or without notice, if you breach these Terms, if we are required to do so by law, or if we reasonably need to in order to protect the Service or other users. We may also discontinue the Service, in whole or in part, as described in Section 14.
On termination, your right to use the Service ends. Sections that by their nature should survive termination (including those on intellectual property, disclaimers, limitation of liability, indemnity, and governing law) will continue to apply. Handling of your data after termination is described in our Privacy Policy.
14. Changes to the Service and to These Terms
We are actively developing the Service and may add, change, suspend, or remove features at any time. We will try to avoid material disruption where reasonable, but we are not obliged to maintain any particular feature.
We may update these Terms from time to time. If we make material changes, we will provide reasonable notice, for example by posting the updated Terms in the Service or by email. The updated Terms take effect on the date stated, and your continued use of the Service after that date means you accept them. If you do not agree, you should stop using the Service and may cancel your Subscription.
15. Governing Law and Dispute Resolution
These Terms and any dispute arising out of or in connection with them or the Service are governed by the laws of Singapore, without regard to conflict-of-laws principles. The courts of Singapore will have jurisdiction, subject to any mandatory rights you may have under the law of your country of residence.
Before starting formal proceedings, we encourage you to contact us so we can try to resolve the matter informally. At Ultropic’s sole discretion, disputes may be referred to the Singapore International Arbitration Centre in lieu of courts.
16. General
• If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force, and the unenforceable provision will be applied as nearly as possible to its original intent.
• 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 consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets, or by operation of law.
• These Terms, together with our Privacy Policy, are the entire agreement between you and us regarding the Service.
