Data Deletion Instructions — Tredane

Versão em português: Instruções para exclusão de dados

Last updated: 27 Oct 2026

This page explains how to request deletion of your personal data processed by Tredane, a service of LUCIMARK INOVA SIMPLES (I.S.) (Brazil), including data received through WhatsApp (Meta’s WhatsApp Business Platform / Cloud API). For more details, see the Privacy Policy.

1. If you are a patient or client of a clinic

Your WhatsApp conversations with a clinic that uses Tredane belong to that clinic, which is the controller of the data. You can request deletion in two ways:

1. Directly with the clinic you talked to. The clinic owner can delete your contact in the Tredane dashboard.

2. By email to Lucimark: write to privacidade@tredane.com with:

   • Subject: Data deletion - Tredane (or Exclusão de dados - Tredane)
   • the WhatsApp number used in the conversation (with country and area code, e.g. +55 61 9XXXX-XXXX);
   • the name of the clinic you talked to (if known);
   • your name.

   We will forward the request to the clinic and support the deletion. We may ask for confirmation that the request is yours (for example, a message sent from that number).

What is deleted: all your messages, attachments (photos, audio and documents), conversations, AI reply suggestions and follow-up records at that clinic. Appointments already booked are kept only in anonymised form, without your name or number, and Pix charges are no longer linked to you.

What may be kept:

• a technical marker of your number at that clinic, used only to prevent the contact from being automatically recreated by old messages redelivered by WhatsApp;
• audit records without message content, name or phone number;
• data we are legally required to keep, such as financial records of Pix charges held by the payment provider, kept for 5 years.

If you write to the clinic again after deletion, a new conversation may be created from that new message.

Important: deletion in Tredane does not delete messages stored on your phone, on the clinic’s phone or in your WhatsApp account. Use WhatsApp’s own options for that.

2. If you are a clinic or a clinic user

• Delete a contact (patient): the clinic owner can delete the contact in the Tredane dashboard. Deletion is immediate and has the effect described above.
• Close the clinic account and delete all data: the clinic owner writes to privacidade@tredane.com with the subject Data deletion - Tredane, the clinic name and the connected WhatsApp Business number. Once we confirm the request, we disconnect the WhatsApp integration and permanently delete, within 30 days: all conversations, messages, attachments, contacts, appointments, charges, clinic settings, integration credentials and notification subscriptions. All clinic users’ access is revoked and pending invitations are cancelled. We keep only audit records without message content, a record that the account was closed and a record that the clinic’s WhatsApp Business number was disconnected.
• Delete your user account (staff or owner): write to the same address with the email of your account. We remove your access to clinics and your login account at our authentication provider (Clerk) (this deletion is done manually by the Lucimark team).

3. Timelines

• We acknowledge your request within 5 business days.
• We complete deletion of a patient’s or user’s data within 15 days of confirming the request.
• We complete full deletion of a clinic’s data within 30 days of account closure.
• When done, we send a confirmation by email.
