Terms of Service

Last updated: November 6, 2026

These terms govern the use of ZTalk (https://ztalk.chat), a multichannel customer service platform by Zmais.Tech LTDA (Brazil, CNPJ 62.421.216/0001-88). By creating an account or using the service, you accept these terms and our Privacy Policy.

1. The service

ZTalk lets businesses connect messaging channels (WhatsApp, Instagram, Messenger, Telegram and website chat), serve their customers as a team, use automations and AI features, and follow reports. The features and limits of each plan are on the pricing page.

2. Account and team

  • You must be at least 18 and authorized to act for the business.
  • You are responsible for the account information, for keeping the password safe and for what your team members do in the panel.
  • Tell us through the website chat if you suspect unauthorized access.

3. Acceptable use and channel policies

When you use WhatsApp, Messenger or Instagram through ZTalk, you also agree to comply with Meta's terms and policies, including the WhatsApp Business Messaging Policy, the WhatsApp Commerce Policy and the WhatsApp Business Platform terms. In particular, you must not:

  • message people who have not opted in or who asked not to be contacted, or send spam or unsolicited bulk messages;
  • send illegal, misleading, offensive or discriminatory content, or content that infringes others' rights;
  • offer products or services prohibited by the WhatsApp Commerce Policy;
  • use the service for fraud, scams, phishing or to collect sensitive data without a legal basis;
  • try to bypass technical limits, access other businesses' data or harm the platform.

We may suspend sending or the account in case of violation, including when Meta or another channel restricts your account.

4. Your data and your customers' data

Conversation content and your contacts' data belong to your business, which is their controller under the LGPD. You are responsible for having a legal basis to process them and for informing your customers. We process them as a processor, only to provide the service, as described in the Privacy Policy.

5. Plans, payment and cancellation

  • Paid plans are billed on a recurring basis, according to the chosen plan.
  • Meta charges for WhatsApp Business Platform conversations are billed by Meta directly to your business, separately.
  • You can cancel at any time in the panel; access continues until the end of the period already paid.
  • Non-payment may lead to suspension of the service.

6. Availability and liability

We work to keep the service available and secure, but it depends on third parties (such as Meta and infrastructure providers) and may be interrupted. To the extent permitted by law, we are not liable for indirect damages, lost profits, or failures and blocks caused by third-party channels.

7. Intellectual property

The software, the ZTalk brand and the website content belong to Zmais.tech or its licensors. These terms do not transfer any rights to them.

8. Termination

You can delete your account at any time (see https://ztalk.chat/data-deletion). We may terminate accounts that violate these terms. After termination, data is handled as described in the Privacy Policy.

9. Changes, governing law and contact

We may update these terms; relevant changes will be announced in the panel. Brazilian law applies.
