Terms of use

1. The service

Zay.ia is an artificial intelligence assistant that serves a professional’s clients on her WhatsApp: it answers questions based on her setup, books, reschedules, cancels and sends reminders.

2. Who can use it

Professionals aged 18 or over who work for themselves and have a WhatsApp Business number they can connect to the service.

3. Your responsibilities

• Keep your services, prices, durations, hours and address correct and up to date: the assistant answers based on them.
• Have the right to use the connected number and comply with WhatsApp and Meta terms and policies, including those on marketing messages and on clients who ask to stop receiving messages.
• Tell your clients, where needed, that the WhatsApp service uses a virtual assistant, and handle their requests about their own data.
• Keep your account access safe and tell us if you suspect misuse.

4. Limits of the assistant

• It introduces itself as the professional’s assistant and does not pose as her.
• It gives no clinical guidance and recommends no procedures: health topics are passed on to the professional.
• When it lacks the information, it alerts the professional instead of making up an answer.
• Being an automated system, it can make mistakes. The professional is responsible for following conversations and to-dos, and can take over any conversation at any time.

5. Price and payment

The price of the service will be shown before any charge. In the pilot, the first two weeks are free. Before charging, we will tell you the payment method and the current price, and you can cancel at no cost during the free period.

6. Canceling

You can cancel whenever you want by writing to admin@zay.ia.br. When you cancel, the service ends and, if you ask, we delete the data (Data deletion page, reply within 15 days); the Privacy policy explains how data is handled. We may suspend or end accounts used for fraud, abuse, spam or breach of these terms or of Meta’s terms.

7. Availability and liability

We work to keep the service running, but it depends on third parties such as WhatsApp (Meta), hosting and language models, and may be unavailable or change for reasons outside our control. Nothing here limits rights that the law guarantees and that cannot be waived.

8. Intellectual property

The software, the Zay.ia brand and the website texts belong to 2MS Serviços em Tecnologias Ltda. The data and content you enter remain yours; you allow us to use them only to provide the service.

9. Changes and governing law

We may update these terms; relevant changes will be announced with reasonable notice. Brazilian law applies.
