Privacy notice

This notice explains what personal data HME84 handles when you use hme84.co (the contact form, the chat and the site assistant), why we use it, which providers process it, how long we keep it and how to exercise your rights under Mexico's Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP).

Data controller

HME84, run by Erik Garcés and based in Mexico City, Mexico, is responsible for the data described in this notice. For any privacy matter, write to contact@hme84.co.

What data we handle, by channel

  • Contact form. Your name, email address, the message you write and the type of inquiry you choose. The form does not store this data in a database: it is sent as an email to HME84's inbox.
  • Chat and site assistant. The messages you write, the recent conversation history, a session identifier, the language and the page you are writing from. The language model uses this data to generate a response, and the conversation is stored in our infrastructure.
  • Data in your browser. The chat stores the session identifier, the messages and, if you leave them, your contact details on your device (the browser's local storage) so you can pick up the conversation again.
  • Contact details left in the assistant. If you choose to leave your details in the assistant, we record your name, email, a summary of your need and an intent profile (see below), and send them to our follow-up system.
  • Security. To limit abuse and keep technical logs, we use a hashed version of your IP address, so the IP itself is not stored in plain form.

Please do not share passwords, payment details or confidential materials through any channel. We do not ask for sensitive personal data.

Purposes

We use this data to:

  • Answer your questions about HME84 and its services.
  • Understand your need and follow up on a possible proposal or diagnosis.
  • Run the chat: generate responses and keep the context of the conversation.
  • Protect the site: limit abusive use and detect failures.

We do not use your data for other purposes without your consent, except where the law allows it. We do not sell or rent personal data.

Summary and intent classification

The chat runs on artificial intelligence. To follow up, it may summarize your need and classify how clear it is and what level of intent it shows (for example, whether you are just exploring or ready to start a project). That classification helps prioritize follow-up. We do not make automated decisions that have legal effects on you or that affect you in a similarly significant way.

Providers and transfers outside Mexico

To run the site we use providers that process data on HME84's behalf and only to deliver their service to us:

  • Cloudflare: site infrastructure and storage of chat conversations.
  • OpenAI: the language model that generates the chat's responses.
  • Resend: delivery of contact form emails.

These providers may process data on servers located outside Mexico. When you use the form or the chat, your data is transferred abroad for that purpose.

How long we keep data

  • Chat conversations on our server: 30 days, after which they are deleted automatically.
  • Chat data in your browser: 7 days, or 30 days if you leave your contact details. You can reset it sooner with the chat's "New" button or by clearing the site's data in your browser.
  • Contact form messages and assistant contacts: 24 months from our last contact with you, after which they are deleted.
  • Security logs: kept temporarily, only as long as technical operation requires.

Your rights (ARCO) and withdrawing consent

You can access your data, ask for it to be corrected or deleted, or object to its use (known in Mexico as ARCO rights). You can also withdraw your consent. To do so, email contact@hme84.co with your name, the email address you used and what you are requesting. If your request concerns the chat, tell us roughly when you used it.

The LFPDPPP sets a maximum of 20 business days to communicate the response to your request.

Changes to this notice

We may update this notice if the site, our providers or the law change. The current version will always be published on this page with its update date.
