This page explains how to request the deletion of your personal data processed by 16PCT Publicidade LTDA (CNPJ 58.924.674/0001-62), referred to here as "16pct".

This page meets the Data Deletion Instructions URL requirement of the Meta Platform Terms (the Data Handling section) for the API 16pct application (App ID: 1561514651731652).

How to request deletion

Send an email to equipe@16pct.com.br with:

1. Subject: Solicitação de Exclusão de Dados
2. In the body of the email, provide:
   • Your full name
   • Email associated with the data
   • Associated phone number (if applicable)
   • Advertiser company involved (if you know which 16pct client served you)
   • A brief description of what you want deleted (e.g., "all my WhatsApp conversations with company X" / "my data in the CRM funnel" / "conversion event sent to Facebook")

If you are here via Facebook or Instagram

You were possibly directed to this page because the API 16pct application processed your data on behalf of an advertiser. To delete this data:

1. Send the email described above.
2. Mention in the body: "I came via Facebook/Instagram" and, if possible, which advertiser or brand contracted 16pct to serve you.
3. Identify as best as possible which data you want deleted (email, phone, ad_id, or event ID if you have access to the Meta panel).

Response time

• Initial confirmation: within 2 business days after receipt.
• Completion of deletion: within 15 business days.
• Completion notice: by email, with the list of systems where the deletion was carried out.

What will be deleted

When applicable, we will delete the following data associated with you in our systems:

• WhatsApp conversations captured on behalf of the advertiser.
• Contacts and leads linked to your phone/email.
• CTWA attribution data (ad clicks → conversations).
• Events sent to the Meta Conversions API (historical deduplication).
• Sales records in public forms linked to your CPF/email/phone.
• AI analyses generated from your conversations.

For each one, we will carry out the deletion both in the main database (Supabase) and in backups, within the backup rotation cycle (up to 30 days).

What may remain (after deletion)

Due to legal or contractual obligations, we may retain:

• Tax and accounting records (5 years, Brazilian Federal Revenue Service).
• Anonymized security audit logs (up to 12 months).
• Data already irreversibly anonymized (non-identifiable).
• Data that the advertiser (controller) is obligated to keep under legislation applicable to it.

Important limitations

Data we send to Meta

When 16pct sends an event to the Meta Conversions API on behalf of an advertiser, that event then lives within Meta's infrastructure (Facebook, Inc.). After it is sent:

• We can delete the local copy of the event (from our database).
• The copy at Meta follows Meta's retention policy, not ours.

To delete data within Meta, you must also use Meta's own controls:

• Facebook: https://www.facebook.com/help/contact/1638046109617856 (Access/Deletion Request)
• Privacy settings of your Meta account: https://accountscenter.facebook.com

When the advertiser is the controller

If 16pct processes your data on behalf of an advertiser client (which is the case in most situations), the controller is the advertiser. We can:

• Delete the data in our systems, and
• Forward your request to the advertiser so that it takes the actions that only the controller can take.

In all cases we will confirm by email what was done.

Identification

To protect your privacy, we may request additional information to confirm your identity before carrying out the deletion. This step prevents malicious third parties from erasing your data without your authorization.
