Terms of Use

Section 01

Acceptance of Terms

By accessing or using any ControlHF product — including the mobile application, the web application at app.controlhf.com, and the clinician portal at care.controlhf.com (collectively, the "Services") — you agree to be bound by these Terms of Use and all policies incorporated herein by reference, including our Privacy Policy and HIPAA Notice of Privacy Practices.

If you do not agree to these Terms, you must not access or use the Services. Your continued use of the Services following any update to these Terms constitutes acceptance of the revised Terms.

Age requirement

You must be at least 18 years of age to create an account and use the Services independently. Users between the ages of 13 and 17 may use ControlHF only under the supervision and with the consent of a parent or legal guardian, who must create and manage the account on the minor's behalf.

Section 02

Description of Services

ControlHF operates a remote patient monitoring (RPM) platform designed specifically for individuals living with heart failure and the clinical teams who care for them. Our Services include:

• Mobile application: Available on iOS and Android, the ControlHF app allows patients to log daily symptoms, sync biometric readings from connected devices, receive personalized alerts, and communicate with their care team.
• Web application (app.controlhf.com): A browser-based portal providing the full feature set of the mobile app, accessible from any device.
• Care portal (care.controlhf.com): A clinical dashboard where authorized physicians, nurses, and care managers can view patient monitoring data, configure alert thresholds, and document clinical interventions for RPM billing.

ControlHF provides clinical decision support tools. All clinical decisions, including medication changes, care escalations, and diagnoses, are made exclusively by licensed healthcare professionals.

ControlHF does not provide ambulance dispatch, emergency medical services, or real-time clinical intervention. Our alert system is designed to notify your care team during normal clinical operations and does not guarantee immediate clinical response.

Section 03

User Accounts

To access most features of the Services, you must create a ControlHF account. By creating an account, you agree to the following:

Account creation

• Accurate information: You must provide truthful, accurate, current, and complete information during registration and keep your account information updated at all times. Providing false health data may result in inaccurate monitoring and could pose a risk to your health.
• One account per person: Each individual may maintain only one active patient account. Clinicians may have a separate care portal account in addition to a patient account.
• Age verification: You affirm that you are 18 years of age or older, or that a parent or guardian is creating and supervising the account on behalf of a minor with appropriate consent.

Password & security

• Password security: You are responsible for maintaining the confidentiality of your password. Choose a strong, unique password and do not reuse passwords from other services.
• No sharing: You may not share your login credentials with any other person. Each authorized care team member must have their own account provisioned through the care portal.
• Breach notification: You must notify us immediately at security@controlhf.com if you suspect unauthorized access to your account.

Account suspension & termination

We reserve the right to suspend or terminate accounts that violate these Terms, provide false information, engage in abusive behavior, or pose a security risk. In cases where suspension is for a suspected violation rather than confirmed misconduct, we will notify you and provide an opportunity to respond before permanent termination.

Section 04

Medical Disclaimer

ControlHF is a clinical decision support tool. The information, alerts, trend analyses, and risk scores provided through the Services are intended to assist your care team — they are not a diagnosis, a treatment recommendation, or a substitute for professional medical judgment.

• Clinical decision support only: All outputs from ControlHF — including alert notifications, risk stratification scores, and trend summaries — are informational aids. They do not replace the clinical judgment of your physician or care team.
• Licensed physicians make all clinical decisions: Every care protocol action taken in response to ControlHF data is the responsibility of a licensed healthcare professional. ControlHF Inc. does not make clinical decisions.
• No doctor-patient relationship: Use of the ControlHF platform does not create a doctor-patient relationship between you and ControlHF, Inc. or any of its employees, officers, or contractors.
• Consult your physician: You should discuss all changes to your symptoms, weight, or health status with your physician promptly, regardless of whether the app generated an alert. Do not delay seeking medical care based on the absence of an alert.

Section 05

Acceptable Use

You agree to use the Services only for their intended lawful purposes. The following uses are expressly prohibited:

You may not

• Reverse engineer the platform: Decompile, disassemble, reverse engineer, or attempt to derive the source code of any part of the Services, including the mobile applications and care portal.
• Share your login credentials: Provide your username or password to any third party. Each user must have their own account. Sharing credentials undermines data security and your account's clinical integrity.
• Submit false health data: Enter inaccurate, fabricated, or deliberately misleading health data, symptoms, or readings. Doing so may result in incorrect clinical alerts, inappropriate care decisions, and real risk to your health or the health of others.
• Harass or harm others: Use the Services to send threatening, abusive, or harassing messages to other users, care team members, or ControlHF staff.
• Circumvent security controls: Attempt to bypass, disable, or interfere with any security features, access controls, or rate limits of the platform.
• Scrape or extract data: Use automated tools to extract, scrape, or copy data from the Services, including patient data, clinical protocols, or platform infrastructure details.
• Violate applicable law: Use the Services in violation of any applicable local, state, national, or international law or regulation, including HIPAA and other health privacy laws.

ControlHF reserves the right to investigate suspected violations and may report confirmed violations to appropriate authorities where required by law.
