Refunds and cancellation

How the Free plan, billing, cancelling and refunds work at wuapi, operated by Zavu Labs Inc.. This page is part of the terms.

Last updated September 26, 2026

Free plan

  • Every organization starts on Free, with no card and nothing charged: 1 number, 2,000 messages and 0.5 GB of proxy traffic a month, counted per calendar month in UTC.
  • When a monthly limit is reached, the number pauses until the month ends or you upgrade. It stays linked and reconnects on its own.
  • Upgrading collects a card in Stripe Checkout and starts the paid subscription that day. There is no trial.
  • Proxy traffic used on Free is never billed, including in the month you upgrade.

Billing

  • Prices are in US dollars (USD), before tax. Tax (sales tax, VAT or GST) is calculated at checkout from your billing address and added where it applies.
  • Zavu Labs Inc. is the seller. Payments are processed by Stripe, which runs checkout and sends invoices and receipts on our behalf.
  • Connected accounts are billed monthly, per linked number: $6 for your first number, $4.50 for every one after, and $3.50 from the 51st.
  • Each connected account includes 0.5 GB of proxy traffic a month, pooled across your organization. Traffic past that is billed at $0.99 per GB, on the renewal invoice, or earlier, each time the overage not yet invoiced reaches $10. Nothing is billed twice.
  • Each organization has a monthly cap on proxy overage ($50 unless an owner or admin changes it in Billing). At the cap, or while an invoice is unpaid, proxy traffic is paused until the cap is raised, the month ends or the invoice is paid.
  • Link a number mid-period and you pay for the days left, on your next invoice. Remove one and the unused days come back as a credit on that invoice.
  • Support plans and the White label add-on ($100 a month) are monthly too.

Cancelling

  • Cancel any time from Billing → Manage billing in the dashboard, which opens the Stripe customer portal.
  • Cancellation takes effect at the end of the current billing period. The service keeps working until then, and no new period is charged. The current period isn't refunded in part.
  • When the subscription ends, the organization is back on Free and its limits apply again.
  • Proxy traffic past the allowance in the last period can still appear on the final invoice.
  • A support plan is cancelled on its own, from the same portal, and runs until the end of the period you paid for.

Refunds

  • Your first payment has a 14-day money-back guarantee. That's the first payment of the usage subscription, or of a support plan. Ask within 14 days of it and it's refunded in full.
  • Renewals after the first payment aren't refunded, except where the law requires it. Cancel before a renewal to avoid the next charge.
  • Billing errors and duplicate charges are refunded in full, whenever they happened.
  • Nothing else already invoiced is refunded. That includes a number WhatsApp restricted or banned.
  • Where the consumer law of your country gives you a stronger right, that right applies.
  • A refunded subscription ends, and access ends with it. Refunds are processed through Stripe, to the original payment method.

How to request

Email support@wuapi.dev with the invoice number and what went wrong. For the money-back guarantee, write within 14 days of your first payment. Invoices are under Billing in the dashboard. We process the refund through Stripe. Other ways to reach us are on the contact page.
