A tool for clarity,

not a diagnosis.

This document outlines the strict clinical boundaries of the Meridian engine and your explicit responsibilities in verifying probabilistic AI extractions.

Scroll for boundaries
Liability 01

You Verify The Results

While Meridian uses state-of-the-art on-device Apple Intelligence and Semantic Grounding, Optical Character Recognition and NLP technologies are inherently probabilistic. Mistakes can and do happen.

Physical Artifacts

Creases on paper, faded ink, unusual table layouts, or highly complex laboratory sheets can result in missed biomarkers, incorrectly extracted values, or misaligned units.

Explicit Verification

By using Meridian, you explicitly agree that you are solely responsible for cross-checking the extracted data against your original source documents.

Practical Responsibility

You must legally and practically verify the accuracy of your digitized values before drawing conclusions or sharing them with healthcare providers.

Liability 02

Not Medical Advice

The trends, charts, reference ranges, and analytical insights presented in Meridian are for informational and educational purposes only.

Dynamic Ranges

Reference ranges dynamically change based on lab methodologies, age, sex, and underlying conditions. Standard bands shown may not apply to your specific clinical scenario.

Informational Only

A 'High' or 'Low' flag within Meridian does not inherently constitute a medical emergency or a diagnosis.

Professional Judgment

Meridian should never replace professional medical judgment. Always seek the advice of a physician with any questions regarding a medical condition.

Liability 03

Third-Party Subscriptions

The only external third-party SDK integrated into Meridian is RevenueCat. We solely use RevenueCat to process Apple App Store subscriptions and unlock premium features.

Strict Justification

RevenueCat acts as an intermediary with Apple to securely validate that you have paid for a subscription without requiring us to build intrusive user-account systems.

Isolation Guarantee

RevenueCat does not have access to, nor does it process, any of your medical data, biometric information, PDFs, or extracted health trends.

Apple Ecosystem

It operates entirely independently of your local SwiftData clinical sandbox and handles only raw Apple App Store receipt validation.
