Terms of Service

Acceptance

These terms govern the use of Zaplin, a service of NZK TECNOLOGIA LTDA ("NZK", "we"), by the company that subscribes to it and the people it invites ("you").

By creating an account, signing in to the app or using the API, you agree to these terms and to the Privacy Policy. Whoever accepts on behalf of a company declares they have the authority to do so.

The service

Zaplin brings a company's WhatsApp numbers into one workspace: a shared inbox, contacts and groups, pipelines, reminders, campaigns, forms, visual automations, AI features and an integration layer (API, OAuth and webhooks).

Numbers connect by QR code to WhatsApp Web sessions kept by a gateway NZK runs. Zaplin is not affiliated with WhatsApp or Meta, and does not use the official WhatsApp Business API.

Account and workspace

• You sign in with a link sent to your email, or with Google or Apple. Keep access to your email secure: whoever controls it controls your account.
• The workspace owner invites members and sets their roles (Owner, Admin, Manager, Agent and Viewer) and scopes. The company answers for what its members, service accounts and connected apps do in the workspace.
• Only the owner manages the subscription and can delete the workspace.
• Account information must be true and up to date.

WhatsApp and your numbers

You only connect numbers the company has the right to use, and their use remains subject to WhatsApp's and Meta's terms and policies.

WhatsApp may restrict or block a number at any time, for example after mass sends to people who did not ask for them. When that happens, Zaplin shows the number as suspended. NZK does not control those decisions and is not liable for blocks caused by how a number is used.

To protect the numbers, campaigns have a pace and limits: up to 5,000 messages per number per day, reached gradually during a warm-up, and contacts can opt out by replying SAIR.

Acceptable use

You may not use Zaplin to:

• send messages to people who did not agree to receive them, or keep sending to people who asked to opt out;
• spam, scams, phishing, harassment, discrimination or any unlawful content;
• infringe third parties' rights, including privacy, image and intellectual property;
• process personal data without a legal basis;
• circumvent limits, quotas or security mechanisms, or reach other workspaces' data;
• copy, resell or reverse engineer the service without written permission.

Before each campaign, you confirm the recipients agreed to receive messages. NZK may suspend access for anyone who breaks these rules, as described under Suspension and deletion.

Your data and your contacts' data

The content you put into Zaplin belongs to your company. NZK uses it only to provide the service, as the Privacy Policy says.

For your contacts' data, your company is the controller and NZK is the processor (see Who decides about each piece of data). It is up to your company to have a legal basis to process it, to inform its contacts and to answer their requests; NZK helps as far as it can.

AI features

AI responses may contain mistakes. Review what it produces before using it in important decisions. Messages an automation sends with AI-generated text are your company's, like any other.

The Assistant asks for confirmation before risky actions. Each Run Prompt execution and each Assistant reply counts as one AI call against your plan's quota.

Integrations and API

API keys, service accounts and OAuth apps act within the scopes you grant. Keep keys safe: they are shown only once and can be revoked at any time.

Webhooks and HTTP requests send data to the destinations you configure, and those destinations are your company's responsibility. The API has per-key rate limits.

Plans and payment

• Zaplin is sold as a monthly or annual subscription per workspace, in Brazilian reais, by card through Stripe. Plans, prices and limits are on the site.
• A new workspace has a 7-day free trial, with no card, with the Professional plan's limits. When the trial ends without a subscription, the workspace becomes read-only, with no connected numbers, until it subscribes to a plan.
• Extra numbers and members are charged on the plan's cycle, prorated for the remaining days. AI call and automation run packs are one-time purchases, never expire and are used after the month's quota.
• An upgrade is charged at once, with credit for unused days; a downgrade applies at renewal and never below current usage.
• When the quota runs out and there is no pack, Run Prompt and the Assistant pause and automations stop starting until the renewal or a pack purchase.
• If a payment fails, the plan continues while new attempts are made; without payment, the workspace is suspended and becomes read-only.

Price changes apply from the next renewal and are announced in advance by email.

Cancellation and guarantee

No lock-in: the owner cancels at any time, right in the dashboard. The plan runs to the end of the period already paid and does not renew.

7-day guarantee: if Zaplin is not right for you, ask within 7 days of the first payment at contato@zaplin.com.br and we refund the first monthly fee.

Outside the guarantee, periods already paid are not refunded pro rata.

Suspension and deletion

A workspace cancelled or suspended for non-payment stays read-only, with export, for 60 days and is then deleted for good, as the Privacy Policy says.

The owner can delete the workspace at any time. Deletion is immediate and final: the numbers' sessions end, the subscription is cancelled at once without a refund, and the data and files are deleted.

NZK may suspend a workspace that breaks these terms or puts the service or other customers at risk, giving notice beforehand whenever possible.

Availability and support

We work to keep Zaplin available, but maintenance and outages may happen, including at WhatsApp and other providers the service depends on.

Support answers on the WhatsApp shown on the site and at contato@zaplin.com.br. Assisted onboarding helps set up numbers, team and pipelines at the start.

Intellectual property

The software, the Zaplin brand and the site's content belong to NZK. The subscription gives your company the right to use the service while it lasts, without transferring any of those rights. Suggestions you send us may be used to improve the product.

Changes to these terms

We may update these terms when the service changes. The date at the top shows the version in force, and significant changes are announced by email or in the app before they take effect. Continuing to use Zaplin after that means accepting the new version.
