Terms of Service

What Zaiketz is

Zaiketz (“we”) is a Japan-based company providing customer-communication automation services to small and medium businesses, including sending WhatsApp messages — appointment reminders, confirmations and review requests — on behalf of the business that hires the service. These terms govern the contracting business's (“you” or “client”) use of our services.

Acceptable use

You agree to use the service only to communicate with people who are already your own customers or legitimate contacts, and who have consented to receive messages from you. Using the service to send unsolicited messages (SPAM) is prohibited, as is using purchased or non-consented contact lists, or any misleading, unlawful content or content that infringes third-party rights. We may suspend access for anyone who violates this rule.

Responsibility for third-party platforms

The service delivers messages through platforms operated by third parties — today, the official WhatsApp API (Meta) and, where applicable, an SMS provider. Use of those platforms is subject to their own terms of service (Meta/WhatsApp, Google, where any of its integrations are used). It is the client's responsibility to know and follow those terms — including Meta's messaging policies and obtaining proper consent from its own customers before sending any message.

Disclaimer of liability

We do not control decisions made by third parties. We are not responsible for account blocks, suspensions or bans applied by Meta/WhatsApp or other providers, nor for outages or pricing changes in their APIs — even when these affect how the service works or what it costs. We do our best to adapt the service to such changes, but they are outside our control.

Service availability

We work to keep the service running reliably, but we do not guarantee uninterrupted operation. Interruptions may occur for maintenance, updates, or for reasons outside our control.

Changes to these terms

We may update these terms — for example, to reflect changes to the service or to the third-party platforms we use. The “last updated” date at the top marks the current version, and material changes are ordinarily communicated to the client with reasonable advance notice.
