Privacy Policy and Notice of Privacy Practices

Effective date: October 29, 2026

MacArthur Gastroenterology Inc. (Mac GI, “we,” “us” or “our”) respects your privacy. This page has two parts:

• Part 1: Website Privacy. How macarthurgi.com collects and uses information when you visit our website, book online, pay or sign up for emails.
• Part 2: Notice of Privacy Practices. How we use and protect your health information as a patient, and your rights under the Health Insurance Portability and Accountability Act (HIPAA) and California law.

If you have questions, contact our Privacy Officer using the details at the end of this page.

Part 1: Website Privacy

Information you give us

• Online booking: your name, email, phone number, the service you choose, your appointment time and any notes you add.
• Online payment: payments are handled by our payment processor, Stripe. Your card details go directly to Stripe. We do not store your full card number.
• Guide and email sign-ups: your name and email address, and whether you asked to receive health updates.
• Contact and intake forms: the information you choose to enter.

Please do not send medical records, insurance policy numbers or insurance card images through our website forms. Bring them to your visit or ask our office for a secure way to share them.

Information collected automatically

• Technical information: like most websites, our web server and security tools record information such as your IP address, browser type, device type, the pages you visit and the date and time of your visit. We use this to keep the website secure and working properly.
• Cookies: we use cookies and similar technologies that are needed for the website to work, such as keeping your place during booking and checkout, protecting the site from attacks and remembering your choices. Our payment system may also record how you arrived at our website when you make a payment.
• No advertising trackers: we do not use advertising pixels or third-party tracking tools to follow you across other websites, and we do not use website tracking to build advertising profiles.
• Embedded content: some pages show maps from Google Maps and use fonts from Google Fonts. When these load, Google may receive your IP address and browser information under Google’s own privacy policy.

You can set your browser to block or delete cookies. Some features, such as booking and payment, may not work without them.

How we use website information

• To schedule, confirm and remind you about appointments
• To process payments and refunds
• To send the guides and emails you request
• To answer your questions and provide customer service
• To keep our website secure and improve how it works
• To meet legal requirements

Health information you provide while booking or receiving care is protected as described in Part 2.

Emails

If you request a guide or sign up for updates, we use Mailchimp to send our emails. You can unsubscribe at any time using the link at the bottom of every email. Appointment confirmations and reminders are sent separately so you do not miss information about your care.

Who we share website information with

We share information only with service providers who help us run our website and practice, such as our website host, our online booking system, our payment processor (Stripe) and our email service (Mailchimp). They may use the information only to provide services to us. We may also share information when required by law.

We do not sell your personal information, and we do not share it for targeted advertising.

Patient portal and other websites

Our website links to the IMS Care Patient Portal and to other websites. Those sites have their own privacy policies. We encourage you to read them.

Social media

We use publishing tools to share our own website articles and announcements to our official Facebook Page. This does not send visitor or patient information to Facebook. Comments, likes and messages on our Facebook Page are governed by Facebook’s privacy policy. Please do not share personal health information on social media.

How long we keep information

We keep booking and payment records as long as needed to provide services and to meet medical, tax and legal record-keeping requirements. Email sign-up information is kept until you unsubscribe or ask us to delete it.

Security

Our website uses encrypted connections (HTTPS). We use administrative, technical and physical safeguards to protect your information. No website or method of transmission is completely secure, so please contact us by phone for sensitive matters.

Your choices and California privacy rights

• You can ask to see, correct or delete the personal information you gave us through our website, unless we must keep it for medical or legal reasons. Contact our Privacy Officer.
• You can unsubscribe from marketing emails at any time.
• California residents may ask whether we share personal information with third parties for their direct marketing purposes. We do not.
• We do not use your information for targeted advertising, so there is nothing to opt out of. We respect browser privacy signals such as Global Privacy Control.
• Your medical information is also protected by the California Confidentiality of Medical Information Act (CMIA).

Children

Our website is not directed to children under 13, and we do not knowingly collect personal information from children under 13 online. Parents or guardians should book appointments for minors by calling our office.

Part 2: Notice of Privacy Practices

This notice describes how medical information about you may be used and disclosed and how you can get access to this information. Please review it carefully.

Our duties

We are required by law to keep your protected health information (PHI) private, to give you this notice of our legal duties and privacy practices, to follow the notice currently in effect and to notify you if a breach of your unsecured PHI occurs. PHI is information that identifies you and relates to your health, your care or payment for your care.

How we may use and share your health information

• Treatment: to provide and coordinate your care, including sharing information with other doctors, hospitals, laboratories and pharmacies involved in your care.
• Payment: to bill and get paid by you, your health plan or others. If you pay for a service in full out of pocket, you can ask us not to share information about that service with your health plan.
• Health care operations: to run our practice, improve quality, train staff and meet legal and accreditation requirements.
• Appointment reminders and health information: to remind you of appointments and tell you about treatment options or services that may interest you.
• Business associates: to companies that perform services for us under written agreements that require them to protect your information.
• Family and friends: to a family member, friend or other person involved in your care or payment, unless you tell us not to.

Other uses and disclosures allowed or required by law

We may share your information without your authorization when the law allows or requires it, including:

• Public health activities, such as reporting disease, injury, product problems or reactions to medicines
• Reporting suspected abuse, neglect or domestic violence to authorities
• Health oversight activities, such as audits, inspections and licensing
• Lawsuits and legal proceedings, in response to a court order, subpoena or other lawful process
• Law enforcement purposes, as permitted by law
• Coroners, medical examiners and funeral directors
• Organ, eye and tissue donation
• Research approved under privacy protections
• Preventing a serious threat to health or safety
• Specialized government functions, such as military and national security
• Workers’ compensation
• As otherwise required by federal, state or local law

Uses that require your written permission

We will ask for your written authorization before we use or share your information for marketing, before any sale of your information and for most uses of psychotherapy notes. Other uses not described in this notice also require your written authorization. You may revoke an authorization in writing at any time, except where we have already acted on it.

California law may give extra protection to certain information, such as HIV test results, mental health records and genetic test results. We follow these stricter laws when they apply.

Substance use disorder treatment records

If we receive records from a federally assisted substance use disorder treatment program, those records have special protections under federal law (42 CFR Part 2). We generally will not use or share them for treatment, payment or health care operations without your written consent, except as the law permits. These records, or testimony describing them, will not be used or shared in a civil, criminal, administrative or legislative proceeding against you without your written consent or a court order, after notice and an opportunity to be heard, together with a subpoena or other legal requirement compelling disclosure. Information shared with a recipient that is not subject to these laws may be re-disclosed by that recipient. We do not use these records for fundraising.

Your rights

• Get a copy of your records: you can see or get a paper or electronic copy of your medical and billing records. We may charge a reasonable, cost-based fee.
• Ask us to correct your records: if you think information is wrong or incomplete. If we say no, we will tell you why in writing.
• Ask for confidential communications: for example, that we contact you at a different phone number or address. We will agree to reasonable requests.
• Ask us to limit what we use or share: we are not required to agree, except when you pay in full out of pocket and ask us not to share that service with your health plan.
• Get a list of disclosures: a list of times we shared your information for reasons other than treatment, payment, operations and certain other purposes, for up to six years before your request.
• Choose someone to act for you: a person with medical power of attorney or a legal guardian can exercise your rights.
• Get a copy of this notice: you can ask for a paper copy at any time.
• Be notified of a breach: we will notify you if a breach affects your unsecured information.

To use any of these rights, contact our Privacy Officer.

Complaints

If you believe your privacy rights have been violated, you can file a complaint with our Privacy Officer or with the U.S. Department of Health and Human Services, Office for Civil Rights, at hhs.gov/ocr/complaints, by calling 1-877-696-6775, or by writing to 200 Independence Avenue SW, Washington, D.C. 20201. We will not retaliate against you for filing a complaint.
