Who is responsible for the website

AETHERION ANESTESIA LTDA, CNPJ 62.348.713/0001-06, is responsible for this website and for the data received through its communication channels.

Browsing

This is an informational website; it does not require visitor registration or online payments. We do not use advertising or audience analytics tools. Hosting is provided by Cloudflare, which may process technical data—such as IP addresses, dates, times, and request information—to deliver web pages, secure the service, and identify technical issues.

Language and preference

We store only your chosen language in a preference cookie for up to 180 days. You can change this via the language selector or by clearing your browser cookies. The initial selection is based on your approximate country, as indicated by your hosting provider, without requesting your precise location. If no match is found, we default to Portuguese (Brazil).

Contact via WhatsApp

Clicking a contact link will redirect you to WhatsApp. The suggested message is editable and will only be sent once you choose to send it. Data provided to our team will be used to respond to your inquiry and manage your request, in accordance with the intended purpose and applicable legal obligations.

For your initial contact, simply state the subject and how we can assist you. Clinical information should be shared according to the team’s guidance. WhatsApp has its own terms and privacy policies.

Google Profile and Reviews

We display a selection of excerpts from public reviews found on Dr. Gustavo’s profile, including the authors' names, ratings, and links to the original reviews. The date of the consultation is indicated within the reviews section. These excerpts are stored on the website and are not updated automatically.

Viewing the cards does not load a map, nor does it connect your browser to Google. By opening one of the links to a profile or a review, you access a Google service, which is subject to its own policies. Please refer to the Google Privacy Policy and the Cloudflare Privacy Policy.

Inquiries regarding personal data

To clarify how your data is processed or to exercise your rights, please contact us via WhatsApp +55 (48) 99124-5802. Our team may request the information necessary to verify your identity and process your request.

Data is retained for as long as necessary to fulfill the purpose for which it was collected and to comply with applicable legal obligations. This page may be updated whenever there are changes to our services or data processing practices.
