Acceptance of these terms

By using medcalc.io, or downloading, installing, or using the MedCalc Pro app (together, the “Service”), you agree to these Terms of Service. If you do not agree, do not use the Service. These terms form an agreement between you and VitaliSyn Group (“we”, “us”, “our”).

Eligibility

The Service is intended for use by healthcare professionals, trainees, and students for educational and clinical-reference purposes. You represent that you are using it in that capacity and are legally capable of entering into this agreement.

Not a substitute for clinical judgment

Every calculator, recommendation, and reference value on the website or in the app is provided for educational purposes only. Nothing in the Service replaces clinical judgment, direct patient assessment, local institutional guidelines, or specialist consultation, and must not be used as the sole basis for a clinical decision. You remain solely responsible for verifying any result against current guidelines and your own clinical assessment before acting on it. See also the standalone Medical Disclaimer.

AI-generated content specifically

The app’s optional AI Note feature generates draft text using an AI model. AI-generated content can be incomplete, miss context, or occasionally be incorrect. AI Notes are drafting aids only, clearly labeled as such within the app, and must be reviewed for accuracy by a qualified professional before being added to any medical record. You assume full responsibility for any use of AI-generated content. This section applies equally to any future AI-assisted feature the Service may add that generates content.

Website content accuracy

We work to keep website content — feature descriptions, figures, and any other statements about the Service — accurate and current. Where website content describes the app, the app’s own in-product behavior and this document are authoritative if they differ. If you notice a discrepancy, we’d genuinely like to hear about it: contact@medcalc.io.

No warranty

While clinical content is built and checked carefully, calculators and reference tools of this kind can contain errors, become outdated as guidelines change, or not account for a specific patient’s full clinical picture. THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL “VitaliSyn Group” BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE, INCLUDING ANY CLINICAL DECISION INFORMED BY CONTENT ON THE WEBSITE OR IN THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID US, IF ANY, IN THE 12 MONTHS BEFORE THE CLAIM AROSE. Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you.

Indemnification

You agree to indemnify and hold VitaliSyn Group harmless from any claim, demand, loss, or damage, including reasonable legal fees, arising from your use of the Service, your violation of these terms, or any clinical decision made using information from the Service.

Your data and content

The app has no login system — your data (favorites, history, profile) lives on your device. You are solely responsible for what you enter into calculator fields; please don’t enter directly identifying patient information. See the Privacy Policy for how the optional AI Note, device-limit, and push-notification features handle data that does leave your device, and for what the website itself collects.

Intellectual property

The Service — including its calculators, website content, design, text, and underlying software — is owned by VitaliSyn Group or its licensors and protected by applicable intellectual property laws. You are granted a limited, non-exclusive, non-transferable license to use the Service for its intended purpose. You may not copy, modify, distribute, sell, scrape at scale, or reverse-engineer any part of the Service except as permitted by law.

Subscriptions

Premium is a recurring subscription billed through your platform’s app store — Google Play on Android, or Apple’s App Store where an iOS version is offered — which auto-renews at the end of each billing period unless cancelled beforehand. It can be managed or cancelled at any time through your platform account’s subscriptions page; we don’t handle billing directly and can’t process refunds ourselves outside the platform’s own policies. The website itself has no purchase flow. If a device limit applies to your subscription tier, using it on more devices than permitted may result in Premium access being removed from the device(s) that most recently exceeded that limit; see the Privacy Policy for how this is technically enforced.

Acceptable use

Please use the Service only for its intended purpose as a clinical reference tool. You agree not to: disrupt or attempt to disrupt the website, the app, or backend services; reverse-engineer the app for malicious purposes, including attempting to bypass subscription verification or app-integrity checks; misuse the ad-supported free tier, including generating artificial ad impressions; scrape or bulk-copy website content; or use the Service in any way that violates applicable law.

Third-party services

The app relies on your platform’s billing system, Qonversion, Google AdMob, Google Firebase, and Anthropic to provide certain features, each governed by their own terms. We are not responsible for the availability or performance of these third-party services.

Termination

We may suspend or terminate your access to the Service’s optional online features (AI Notes, push notifications, device verification) at any time for violation of these terms or misuse of the service. Since the app has no accounts, this does not affect your ability to use the app’s core, on-device calculator features or to view the website.

Governing law and disputes

These terms are governed by the laws of India, without regard to conflict-of-law principles. Any dispute arising from these terms or your use of the Service will be subject to the exclusive jurisdiction of the courts located in India, except where applicable local law requires otherwise for residents of your jurisdiction.

Severability and entire agreement

If any provision of these terms is found unenforceable, the remaining provisions continue in full effect. These terms, together with the Privacy Policy, constitute the entire agreement between you and VitaliSyn Group regarding the Service.

Changes

These terms may be updated as the Service evolves — including as new features ship. Continued use after an update means you accept the current version, available in-app at any time from Settings, and at this page.
