Terms of Service

Attuned Labs LLC

Effective Date: March 23, 2026 | Last Updated: April 26, 2026

1. Acceptance of Terms

By downloading, installing, accessing, or using the Follie mobile application (the "App"), you ("User," "you," or "your") agree to be bound by these Terms of Service ("Terms"). These Terms constitute a legally binding agreement between you and Attuned Labs LLC, an Ohio limited liability company ("Company," "we," "us," or "our").

If you do not agree to these Terms, do not download, install, or use the App. Your continued use of the App following any modification to these Terms constitutes your acceptance of such modifications.

These Terms incorporate by reference our Privacy Policy and the Apple Licensed Application End User License Agreement.

2. Nature of the Service

2.1 Clinical Decision Support Tool

Follie is a mobile application that assists licensed healthcare professionals and healthcare professional students in preparing structured anesthetic plans. The App uses deterministic, rule-based logic to generate plan considerations based on user-inputted clinical parameters. The App does not use artificial intelligence, machine learning, neural networks, or large language models. All plan generation is performed entirely on the user's device using predefined clinical rules and reference data. The App provides:

• Rule-based anesthetic plan considerations generated from user-inputted patient and procedural data
• A reference library of anesthetic drug information, dosing ranges, and clinical pearls
• Clinical calculators (BMI, ideal body weight, estimated blood volume, allowable blood loss, MAC, ETT sizing, fluid calculations, and related tools)
• Quick-reference cards for clinical protocols, emergency drug dosing, airway assessment, ASA classification, NPO guidelines, neuraxial anticoagulation timing, and related educational materials
• Quick handoff tools for clinical documentation
• Multilingual medical phrase references for perioperative patient communication

2.5 Optional User Accounts and Cloud Sync

The App offers optional user account creation via Sign in with Apple and Sign in with Google. Account creation is not required to use the App. Users who do not create an account ("guest users") retain full access to all App features, with all data stored locally on their device.

Users who create an account may benefit from cross-device synchronization of their plans, case logs, favorites, and related data. Synced data is stored on servers operated by Supabase, a third-party infrastructure provider, as described in Section 10. Users may delete their account and all associated synced data at any time from within the App's Settings, as described in Section 15.

The App also collects anonymous crash reports via Sentry, a third-party error monitoring service, to improve App stability. Crash reports do not contain clinical data or personally identifiable information. See our Privacy Policy for details.

2.2 Clinical Decision Support Software Classification

Follie is classified as Non-Device Clinical Decision Support (CDS) software under Section 520(o)(1)(E) of the Federal Food, Drug, and Cosmetic Act, as added by Section 3060 of the 21st Century Cures Act. The App meets all four statutory criteria for exclusion from the definition of a "device":

• Criterion 1: The App is not intended to acquire, process, or analyze a medical image or signal from an in vitro diagnostic device or other diagnostic device.
• Criterion 2: The App is intended for the purpose of displaying, analyzing, or printing medical information about a patient or other medical information, and for supporting or providing recommendations to a healthcare professional about prevention, diagnosis, or treatment of a disease or condition.
• Criterion 3: The App is intended for the purpose of enabling a healthcare professional to independently review the basis for the recommendations that the software presents so that it is not intended for the healthcare professional to rely primarily on any of such recommendations to make a clinical decision regarding an individual patient without independently reviewing the basis for such recommendations.
• Criterion 4 (Independent Review): The App uses transparent, deterministic, rule-based logic. All clinical considerations generated by the App are accompanied by visible reasoning, source references, and the underlying clinical rules that produced them. The healthcare professional can review the basis for every consideration, including the input parameters, the applicable rules, and the referenced clinical guidelines. The App is designed so that the user exercises independent clinical judgment and does not rely primarily on the App's output without independent verification.

2.3 Not a Medical Device

Follie is NOT a medical device and is not subject to FDA regulation as a device. The App does not diagnose, treat, cure, mitigate, or prevent any disease or condition. The App does not perform autonomous clinical decision-making. All output is presented as considerations for independent review by a qualified healthcare professional.

2.4 No Doctor-Patient Relationship

Use of Follie does not create a doctor-patient, provider-patient, or any other clinical relationship between you, the Company, or any third party. The App does not and cannot replace the professional judgment of a qualified healthcare provider.

3. User Eligibility

The App is intended exclusively for use by:

• Licensed healthcare professionals, including but not limited to Certified Anesthesiologist Assistants (CAAs), Certified Registered Nurse Anesthetists (CRNAs), anesthesiologists, and other physicians
• Healthcare professional students enrolled in accredited programs, including Certified Anesthesiologist Assistant students, Student Registered Nurse Anesthetists (SRNAs), and anesthesia residents
• Other qualified healthcare professionals or students with relevant clinical training

You must be at least 18 years of age to use the App. By using the App, you represent and warrant that you are either a licensed healthcare professional or a student enrolled in an accredited healthcare professional training program, and that you are at least 18 years of age.

The App may be used without creating an account. Account creation is optional and is available via Sign in with Apple and Sign in with Google. The App does not support email/password registration. Creating an account enables cross-device synchronization of your data but is not required to access any App feature.

4. Purchases, Subscriptions, and Refunds

4.1 One-Time Purchase

Follie is available as a one-time paid purchase through the Apple App Store and Google Play Store. The purchase price is displayed on the applicable app store listing at the time of purchase. The one-time purchase includes the Anesthetic Plan Generator and core app functionality.

4.2 Future Features and Subscriptions

Attuned Labs LLC may introduce additional tools, content, and premium features available through optional subscription plans. We reserve the right to designate new or existing supplementary tools as premium features available through a subscription tier. Core functionality — including the Anesthetic Plan Generator — included at the time of your one-time purchase will remain accessible without a subscription.

The availability, scope, and categorization of tools and features may change over time. Attuned Labs LLC does not guarantee that any specific tool or feature will remain free or remain available indefinitely.

Accounts that purchased the App prior to the introduction of subscription tiers may be eligible for promotional pricing or extended access at our discretion.

4.3 Subscription Terms

If subscription plans are offered, subscriptions will auto-renew unless cancelled at least 24 hours before the end of the current billing period. Subscription management and cancellation are handled through the Apple App Store or Google Play Store. Subscription prices may vary by region and are subject to change with reasonable notice to subscribers.

4.4 Payment Processing

All payments — including one-time purchases and subscriptions — are processed entirely by the Apple App Store or Google Play Store, as applicable. The Company does not receive, process, or store your payment card information, billing address, or other financial details. By making a purchase, you agree to the payment terms of the applicable app store.

The App includes the RevenueCat SDK for in-app purchase management. RevenueCat may be used in the future to facilitate additional purchase options. See Section 10 for details on third-party services.

4.5 Refund Policy

Because the App delivers digital content, all sales are final. The one-time purchase is non-refundable except as required by applicable App Store or Play Store policies. Subscription refunds, if applicable, are governed by the respective platform's refund policies. The Company does not independently process refunds.

5. Acceptable Use

You agree to use the App only for its intended purpose as a clinical decision support and educational tool. You shall NOT:

• Use the App as the sole or primary basis for clinical decisions regarding any individual patient without independently reviewing and verifying the basis for the App's output
• Use the App if you are not a licensed healthcare professional or healthcare professional student
• Reverse engineer, decompile, disassemble, or attempt to derive the source code of the App
• Use the App to develop a competing product or service
• Circumvent, disable, or interfere with security-related features of the App
• Redistribute, sublicense, rent, lease, or lend the App or any portion thereof

6. Clinical Decision Support Disclosure

6.1 Rule-Based Logic

The App generates anesthetic plan considerations using deterministic, rule-based algorithms. The App does NOT use artificial intelligence, machine learning, deep learning, neural networks, large language models, or any form of probabilistic inference. Given the same inputs, the App will produce the same outputs every time. The clinical rules encoded in the App are derived from published medical literature, clinical guidelines, and standard pharmacology references.

6.2 Considerations, Not Directives

All output generated by the App is presented as clinical considerations for your independent review. The App's output does not constitute medical advice, prescriptions, orders, or definitive clinical recommendations. The word "consider" is used deliberately throughout the App to indicate that all suggestions require your independent clinical judgment before being applied to any patient.

6.3 Criterion 4 Compliance (Independent Review)

In accordance with the independent review requirement of Section 520(o)(1)(E) of the FD&C Act, the App is designed so that you can independently review the basis for every consideration the App presents. The App displays the clinical rules, input parameters, referenced guidelines, and reasoning behind each generated consideration. You are expected to exercise independent professional judgment and are not intended to rely primarily on the App's output without independently verifying its basis and applicability to your specific clinical situation.

6.4 Limitations

You acknowledge and agree that:

• The App's rule-based output may not account for every clinical variable relevant to a specific patient
• Drug dosing ranges, interactions, and clinical guidelines referenced by the App may not reflect the most current literature, institutional protocols, or FDA labeling at any given time
• The App does not have access to the patient's complete medical record and generates output based solely on the data you provide
• The App's clinical rules are updated periodically but may not reflect the most recent evidence at all times
• You bear sole responsibility for verifying any App-generated content before applying it in any clinical context

7. Reference Content

The App includes a built-in toolkit of drug references, clinical calculators, emergency drug dosing references, quick-reference cards, and multilingual medical phrase references. This content is compiled from widely published medical literature, standard pharmacology references, and published institutional health education materials. It is written in original language by the Company and is provided for informational and educational purposes only. It is not a substitute for clinical judgment, current drug labeling, or institutional protocols.

Drug dosing ranges shown in the App are informational. The App displays published ranges with weight-based mathematical relationships visible to the user for independent verification. Follie is not affiliated with or endorsed by any medical organization, professional society, pharmaceutical manufacturer, or regulatory body.

7.1 Multilingual Medical Phrases

The App includes a multilingual medical phrase reference feature that provides common perioperative phrases translated into multiple languages. This feature is a communication aid only and does not replace qualified medical interpreter services. The translations are sourced from and verified against published institutional health education materials, including government publications and hospital patient education documents. Each translated phrase includes in-text citations identifying the source reference.

You acknowledge and agree that:

• The multilingual phrase feature is not a substitute for professional medical interpretation services
• Translation accuracy may vary and the Company does not warrant that any translation is clinically appropriate for every situation, dialect, or regional variation
• You are responsible for complying with all applicable laws, regulations, and institutional policies regarding language access and the use of qualified medical interpreters, including but not limited to requirements under Title VI of the Civil Rights Act of 1964, Section 1557 of the Affordable Care Act, and Joint Commission standards
• The Company is not liable for any clinical outcome, miscommunication, or harm arising from the use of or reliance upon translated phrases
• Third-party source materials referenced in this feature are attributed in accordance with standard academic citation practices and remain the intellectual property of their respective authors and publishers

7.2 Geographic Applicability

All clinical content, drug references, dosing guidelines, and clinical protocols provided in the App are based on United States medical standards, guidelines, and regulatory approvals. Drug names, approved indications, dosing ranges, and clinical protocols may differ in other countries. Users outside the United States should verify all information against their local medical standards, institutional protocols, and regulatory requirements. The Company makes no representation that the content is appropriate or applicable outside the United States.

8. HIPAA and Protected Health Information

8.1 Data Processing

For guest users (those who do not create an account), all clinical data entered into the App is processed and stored entirely on the user's local device. No clinical data is transmitted to the Company's servers, to any third-party API, or to any external service.

For users who create an account and enable cloud sync, certain user-generated data — including anesthetic plans, case logs, and favorites — is transmitted to and stored on servers operated by Supabase, a third-party infrastructure provider. This synced data is de-identified and does not contain Protected Health Information ("PHI") as defined under the Health Insurance Portability and Accountability Act of 1996, as amended ("HIPAA"). The App is designed so that users input clinical parameters (such as age, weight, and medical history categories) rather than patient-identifying information (such as patient names, dates of birth, medical record numbers, or Social Security numbers). The synced data, standing alone, does not identify any individual patient.

8.2 Not a Covered Entity or Business Associate

The Company is NOT a "Covered Entity" or "Business Associate" as defined under HIPAA and does not enter into Business Associate Agreements (BAAs). Follie is not designed or intended for use as a component of a covered entity's electronic health record system. The data synced to Supabase servers is de-identified and does not constitute PHI. The App's architecture is designed to avoid the transmission or storage of PHI, and the Company does not assume HIPAA obligations with respect to any data processed by the App.

8.3 User Responsibility

If you are a healthcare provider or student subject to HIPAA or institutional data security policies, you are solely responsible for ensuring that your use of the App complies with those requirements. This includes exercising appropriate judgment regarding what information you enter into the App, particularly on shared, institutional, or unsecured devices. You must not enter patient-identifying information (such as names, dates of birth, medical record numbers, or other direct identifiers) into the App, whether or not you have created an account.

9. Intellectual Property

9.1 Company IP

The App, including all software, content, design, text, graphics, logos, the Follie character and brand identity, clinical rule sets, reference data compilations, and all related intellectual property, is owned by Attuned Labs LLC and protected by copyright, trademark, trade secret, and other intellectual property laws. These Terms do not grant you any ownership interest in the App.

9.2 License Grant

Subject to your compliance with these Terms and upon completion of the applicable purchase, the Company grants you a limited, non-exclusive, non-transferable, revocable license to download and use the App on devices you own or control, solely for your personal, educational, and professional use as a healthcare professional or healthcare professional student.

9.3 User Data

You retain full ownership and control of all clinical data, notes, and other content you enter into the App. For guest users, all data is stored locally on your device and is never transmitted to the Company. For users who create an account, synced data is stored on Supabase servers to enable cross-device synchronization. The Company does not claim any ownership rights to your data, whether stored locally or synced to Supabase. You may delete your account and all associated synced data at any time from within the App's Settings, as described in Section 15.
