Privacy notice

This notice explains what personal data I receive, what I use it for and how you can ask me to correct or delete it. It follows Mexico’s Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP).

Who is responsible for your data?

I am: Dr. Emmanuel Bolaños Betancourt, ophthalmic surgeon. Address for notices: Zona Peatonal Dr. Domenzain 20, Centro, 36100 Silao de la Victoria, Guanajuato, Mexico.

What data do I receive through this site?

This site has no forms, no user accounts and no comments. It never asks for your name, email or phone number. The only data that reaches me is what you choose to send when you:

• message me on WhatsApp from one of the buttons on the site: your number, your profile name and whatever you write;
• call one of my offices: your number and whatever you tell me on the call;
• write to the site assistant (the “Ask me” button): what you type in the chat and the page you ask from. Your messages are processed by an artificial intelligence service (Anthropic) only to answer you, and the conversation is kept so I can check that the assistant answers well. The assistant does not ask for your phone number or health information. Only if you want to book, it asks for your name, the reason for your visit in a few words and the office you prefer, to prepare the WhatsApp message that you choose to send. Please do not type personal medical details there. Anything about your eyes, we look at in person.

What data is collected at the appointment?

When you come in, I open a medical record with your identification details, your history and your test results. Health data is sensitive personal data: I keep it confidential and store it as Mexico’s official medical record standard requires (NOM-004-SSA3-2012).

What do I use your data for?

• Answering your message or call.
• Booking, confirming or rescheduling your appointment.
• Medical follow-up before and after a test or surgery.
• Issuing prescriptions, medical letters or invoices when you ask for them.

I do not use your data for advertising, and I never sell or rent it.

Who do I share your data with?

Only with whoever is needed to treat you: the hospital where your surgery or test takes place, the lab or imaging center I refer you to, or your insurer if you ask me to. Also when a competent authority requires it by law. Outside those cases, I do not share your data without your consent.

What happens when you visit the site?

• No tracking cookies. The site does not use Google Analytics, social media pixels or advertising cookies.

• My own visit measurement. I measure visits with my own system that runs on this same website, with no cookies and nothing shared with Google, Meta or any other advertising company. I record which pages are opened, for how long, how far they are read, where people click, the approximate city and the type of device. I do not store your IP address: together with your browser it becomes a code that changes every day and cannot be reversed, so I do not know who you are and cannot follow you from one day to the next.
• Usage recordings. On some visits I keep a recording of how the page was used (movements and clicks) to find what gets in the way. Anything you type in forms or in the assistant is masked in that recording. Recordings delete themselves after 30 days, and the rest of the measurement data after 400 days. Your browser keeps two small notes (whether you had visited before, and which version of a page you saw when I test two), which you can delete at any time from its settings.
• Anonymous statistics. The site is hosted on Cloudflare, which measures visits and page speed in aggregate and without cookies.
• Maps. My offices page shows one Google map per office. It loads when you scroll to that part of the page; from then on, Google’s privacy policy applies.
• WhatsApp. When you tap a WhatsApp button you leave this site, and WhatsApp’s privacy policy applies.

How to exercise your rights

You have the right to access your data, correct it if it is wrong, cancel it once it is no longer needed and object to a specific use. In Mexico these are known as ARCO rights. You can also withdraw your consent.

To do so, email me at info@oftalmólogo.com or ask in person at either of my two offices. Include your name, what you are asking for and a form of ID. I reply within 20 business days at most.

Medical record data is kept for the period the standard requires even if you ask to cancel it; in that case I block it so it cannot be used for anything else.

Changes to this notice

If I change this notice, the version in force is the one on this page, with its last-updated date at the bottom.
