01Introduction

Med Clinic X is a healthcare technology company dedicated to building modern, privacy-first digital tools for clinicians, patients, and healthcare organizations across the United States. Our product portfolio includes AI-powered patient portals, telemedicine platforms, healthcare automation systems, and a growing suite of Chrome browser extensions designed to support healthcare professionals at the point of care.

This Privacy Policy governs all Chrome Extensions published under the Med Clinic X brand — including healthcare calculators, clinical reference tools, and healthcare productivity extensions currently available or released in the future on the Chrome Web Store.

We believe that privacy is a fundamental right. Our Chrome Extensions are built with a privacy-first architecture: calculations happen locally in your browser, sensitive inputs are never transmitted to our servers, and we request only the minimum permissions necessary to deliver a reliable user experience.

By installing and using any Med Clinic X Chrome Extension, you confirm that you have read and understood this Privacy Policy. If you do not agree with these practices, you may uninstall the extension at any time from your Chrome browser.

02Scope of This Policy

This Privacy Policy applies to all Chrome browser extensions developed, maintained, and published by Med Clinic X, including but not limited to:

Healthcare Calculator Suite

Tools such as BMI Calculator, A1C & HbA1c Calculator, Water Intake Calculator, Lean Body Mass Calculator, QTc Calculator, Anion Gap Calculator, CKD-EPI Calculator, Medication Dosage Calculator, Pediatric Dosage Calculator, IV Flow Rate Calculator, Glasgow Coma Scale Calculator, Dental Implant Cost Calculator, and Invisalign Cost Calculator.

Healthcare Productivity Extensions

Workflow tools, quick-reference aids, and any other browser-based productivity utilities published by Med Clinic X.

Future Extensions

Any new Chrome Extension released by Med Clinic X under this brand will be covered by this policy at the time of publication, unless a specific, separate policy is provided and clearly communicated to users.

This policy does not apply to the Med Clinic X main website (medclinicx.com), the AI Patient Portal platform, or any third-party websites or applications that may be referenced within an extension.

03Information We Collect

Med Clinic X Chrome Extensions are designed to minimize data collection to only what is strictly necessary for the extension to function. We do not operate user accounts or require registration to use any of our extensions.

Calculator Inputs (Processed Locally)

When you use a healthcare calculator, you enter values such as:

Height, weight, age, sex

Blood glucose or A1C values

Serum creatinine, electrolyte levels

Medication doses, patient weight for dosage calculations

Pediatric weight-for-age parameters

Dental procedure estimates or orthodontic treatment inputs

These values are processed entirely within your browser. They are not sent to Med Clinic X servers.

User Preferences & Settings (Stored Locally)

With your permission via the Chrome Storage API, the extension may save:

Unit preferences (metric vs. imperial)

Theme settings (light/dark mode)

Calculation history (if the history feature is enabled by you)

Favorites or pinned calculators

Extension layout configurations

Extension Diagnostic Data (Aggregate Only)

Some extensions may report anonymous, aggregate usage statistics (e.g., which calculator screen was opened, total usage count) to help us improve the product. This data contains no personal identifiers and cannot be linked back to any individual user.

We do not collect your name, email address, location, IP address, or any account information through our Chrome Extensions.

04Information We Do NOT Collect

Med Clinic X Chrome Extensions are explicitly designed to avoid collecting sensitive personal or patient information. Unless a future extension clearly requires specific data with your informed consent and is individually documented, we do not collect:

Browsing history — we do not track which websites you visit

Website content or DOM data — we do not read the content of web pages you browse

Passwords or credentials — we have no access to authentication data of any kind

Personal files or documents — we do not access files on your device

Contacts or address books — we do not read your contacts

Financial information — no payment or banking data is collected

Patient records or EHR data — we do not connect to or extract data from electronic health record systems

Protected Health Information (PHI) — we do not collect, transmit, or store information that qualifies as PHI under HIPAA in our extensions

If a future Med Clinic X product requires handling PHI or personally identifiable information (PII), it will be governed by a separate, clearly disclosed privacy notice and will require explicit user consent before any data collection begins.

05Health Information Privacy

Several Med Clinic X Chrome Extensions are designed to support clinical decision-making by processing health-related data inputs. Examples include:

BMI calculations using height and weight

A1C and HbA1c estimates from blood glucose values

Kidney function scores from serum creatinine and patient demographics

Pediatric medication dosing from weight and age

Cardiac QTc intervals from ECG measurements

Nutritional requirements such as daily water intake targets

Glasgow Coma Scale scores from clinical observation values

**All health-related calculations are performed locally within your browser.** The values you enter into our calculator extensions are never transmitted to Med Clinic X servers, stored in cloud databases, or shared with any third party.

Your health data stays on your device. You are in full control of it at all times.

Med Clinic X Chrome Extensions do not act as covered entities under HIPAA and do not process Protected Health Information (PHI) on behalf of covered healthcare entities. Our calculators are standalone, offline-capable educational tools designed to assist clinicians and informed individuals — not to store, transmit, or manage patient records.

If you are a healthcare professional using these tools in a clinical context, you are responsible for ensuring appropriate use in accordance with your organization's privacy and data governance policies.

06Local Data Storage

Med Clinic X Chrome Extensions use the Chrome Storage API (chrome.storage.local and/or chrome.storage.sync) to save user preferences and, where applicable, calculation history. This means:

What May Be Stored Locally

Unit preferences (e.g., kg vs. lbs, cm vs. inches)

Selected theme (dark mode, light mode)

Calculation history (only if you choose to enable the history feature)

Favorite or bookmarked calculators

Custom configuration settings

Where Your Data Is Stored

Data stored using chrome.storage.local resides only on your device, within Chrome's secure extension storage sandbox.

If chrome.storage.sync is used, Chrome may synchronize your preferences across your signed-in Chrome devices. This synchronization is handled entirely by Google's Chrome infrastructure. Med Clinic X does not have access to your synced data.

You Control Your Data

You can clear all locally stored extension data at any time by:

Navigating to chrome://extensions

Selecting the Med Clinic X extension

Clicking "Details" and then clearing saved data from extension options

Or simply uninstalling the extension, which removes all associated storage

We do not place any data beyond Chrome's standard extension storage boundaries.

07Chrome Extension Permissions

Med Clinic X follows the principle of minimal permissions — we request only what is necessary for the extension to function correctly. Below is an explanation of permissions our extensions may request:

storage

Used to save your preferences (unit settings, theme, history). Without this permission, the extension cannot remember your configurations between sessions.

activeTab (where applicable)

Used only in extensions that display a floating overlay or sidebar on the current page. This permission is limited to the active tab while you are interacting with the extension — the extension does not read, monitor, or transmit the content of any webpage.

No permissions are requested for:

Reading browsing history

Accessing website content in the background

Capturing screenshots or screen content

Reading downloads, bookmarks, or passwords

Accessing the clipboard without user action

Network requests to third-party servers with personal data

If any future Med Clinic X extension requires a new permission not listed here, the updated permission request will be clearly explained in the Chrome Web Store listing and in an updated version of this policy. Users will be notified upon extension update.

08Data Security

Med Clinic X applies security best practices across all phases of Chrome Extension development and maintenance:

Privacy-First Architecture

Extensions are designed from the ground up to process data locally. The absence of data transmission is our primary security feature — data that is never sent cannot be intercepted.

Minimal Permission Surface

By requesting only the permissions necessary for core functionality, we reduce the extension's attack surface and limit the potential impact of any security vulnerability.

Secure Coding Practices

Our extensions are developed following Chrome Extension security guidelines, including:

Content Security Policy (CSP) enforcement

Avoidance of eval() and dynamic code execution

Strict input validation to prevent injection vulnerabilities

Data Minimization

We collect the minimum information necessary. Data that is not needed is simply not collected.

Ongoing Maintenance

We regularly audit and update our extensions to patch security vulnerabilities, maintain Chrome Web Store compliance, and align with evolving best practices in browser extension security.

If you discover a potential security issue in a Med Clinic X Chrome Extension, please contact us immediately at privacy@medclinicx.com.

09Third-Party Services

Med Clinic X Chrome Extensions are designed to be self-contained tools. We do not integrate unnecessary third-party services within our extensions.

What We Do Not Do

We do not sell your data to third parties for any purpose

We do not share calculator inputs or preferences with advertisers

We do not use behavioral tracking or cross-site analytics within our extensions

We do not build user profiles based on extension usage

We do not integrate with advertising networks, data brokers, or marketing platforms

Google Chrome APIs

Our extensions interact with standard Chrome browser APIs provided by Google (e.g., chrome.storage). Your use of Google Chrome is governed separately by Google's Privacy Policy (policies.google.com/privacy). Med Clinic X does not control Google's data practices.

Chrome Web Store

The Chrome Web Store, operated by Google, may collect information related to your extension installation and update activity as part of normal browser operation. This is governed by Google's Terms of Service and Privacy Policy.

Future Integrations

If a future version of a Med Clinic X extension integrates a third-party service (for example, cloud-based AI assistance or telemetry), this will be disclosed in the extension's changelog, Chrome Web Store listing, and in an updated version of this Privacy Policy before users are affected.

10Medical Disclaimer

Med Clinic X healthcare calculator extensions are designed to provide educational and reference information to support clinical decision-making. They are not diagnostic tools and do not replace professional medical judgment.

Important Limitations

Results produced by Med Clinic X calculator extensions:

Are not medical diagnoses

Are not treatment recommendations or prescriptions

Should not be used as the sole basis for clinical decisions

Are provided for informational and educational purposes only

May not account for individual clinical context, comorbidities, or the most current clinical guidelines

Always Consult a Qualified Healthcare Professional

Patients should not use the results of these calculators to self-diagnose or self-treat. Healthcare professionals should use clinical judgment, current evidence-based guidelines, and full patient context when interpreting calculator outputs.

Med Clinic X, Inc. assumes no liability for clinical outcomes resulting from the use of information provided by our Chrome Extension tools. The accuracy of results depends entirely on the accuracy of inputs provided by the user.

These tools are reference aids. They are not substitutes for professional medical training, clinical experience, or consultation with a licensed healthcare provider.

11Children's Privacy

Med Clinic X Chrome Extensions are intended for use by healthcare professionals, medical students, and informed adults seeking health reference information.

We Do Not Knowingly Collect Children's Data

Our extensions are not designed or marketed to collect personal information from individuals under the age of 13. We do not knowingly collect personal information from children.

Pediatric Calculator Tools

Some Med Clinic X extensions include pediatric clinical calculators — such as Pediatric Dosage Calculator and weight-for-age reference tools. These tools are designed for use by healthcare professionals (pediatricians, nurses, pharmacists) who calculate clinical parameters on behalf of pediatric patients. They are professional reference tools, not consumer products intended for use by children.

Inputs entered into these tools are processed locally, are not transmitted to our servers, and are not stored beyond your local device preferences.

If you believe a child under 13 has used a Med Clinic X extension in a manner that resulted in personal data collection, please contact us immediately at privacy@medclinicx.com so that we can investigate and take appropriate action.

12User Rights & Controls

As a user of Med Clinic X Chrome Extensions, you have the following rights and controls:

You can uninstall any Med Clinic X Chrome Extension at any time from the Chrome Extensions manager (chrome://extensions). Uninstalling the extension removes all locally stored data associated with it.

Manage Chrome Permissions

You can review and modify the permissions granted to any Med Clinic X extension by visiting chrome://extensions, selecting the extension, and reviewing the "Permissions" section. You may revoke permissions at any time; note that revoking certain permissions may limit extension functionality.
