Terms of Service

• ECHO is an academic research prototype. It gives screening support only. It does not diagnose hypertension or any other condition and is not a substitute for a health professional.
• It is not a registered medical device. Its scores are uncalibrated and its performance comes from research datasets, not from clinical use.
• Do not make treatment decisions from its results. Confirm blood pressure with a standard measurement and discuss any concern with a health professional. In an emergency, seek medical care immediately.

• Upload only photos you have the right to use: your own, or another person's with their consent.
• Do not include names, ID numbers or other identifying details in photos or file names.
• Use ECHO for personal, educational or research purposes.
• Do not send automated, bulk or scripted requests, and do not try to overload, disrupt, probe or get around the service's protections.

ECHO is provided for demonstration and evaluation. It may be slow, unavailable or changed at any time. To keep it available to everyone, the number of analyses from one connection is limited, and automated requests may be blocked.

ECHO is provided as is, without any warranty of accuracy, completeness or fitness for a particular purpose. To the extent the law allows, the research team is not liable for any decision made or loss suffered from using it.

ECHO uses published open-source models for image preprocessing under their own licences, and the 2019 World Health Organization cardiovascular disease risk model for the optional risk chart. Their authors are credited in the research paper.

These terms are governed by the laws of the Republic of the Philippines. We may update them; the date at the top shows the latest version. Questions can be addressed to the ECHO research team, College of Information and Communications Technology, West Visayas State University, Luna St., La Paz, Iloilo City 5000, Philippines.
