Terms of Use

Hasos is a platform for making and receiving voice calls over WhatsApp, using the customer’s own WhatsApp number, connected as a linked device (via QR code or pairing code). It includes a browser dialer, call recording, reports, mass calling, CRM integrations, an API, webhooks, SIP access and optional artificial intelligence features.

Hasos is not affiliated with, sponsored by or endorsed by WhatsApp or Meta. The platform does not use the official WhatsApp calling API; it depends on the WhatsApp app and infrastructure, which may change at any time without notice.

The platform is intended for businesses and professionals. You must provide accurate information, keep your details up to date and protect your credentials, API keys and device tokens. You are responsible for all activity on your account, including by the users (reps) you invite and the permissions you grant them.

Notify us immediately at suporte@hasos.com.br if you suspect unauthorized use.

You agree not to use Hasos to:

• make unsolicited mass calls (spam), harass, threaten or make any abusive contact;
• commit scams, fraud or identity fraud, or impersonate another person or company;
• violate WhatsApp’s terms, applicable law (including Brazil’s LGPD and Consumer Protection Code) or third-party rights;
• contact people who have asked not to be contacted;
• attempt to circumvent technical limits, test vulnerabilities without authorization or harm the platform and other customers.

We may suspend or terminate accounts that violate these rules, including preventively when there are signs of fraud or abuse.

WhatsApp may restrict or ban numbers it considers to be used abusively — especially new numbers or numbers with a high volume of unanswered calls. Hasos offers protective measures (such as a limit of 1 call per number at a time, anti-burst pacing in mass dialing and a number health panel), but does not guarantee that the number will not be restricted and is not responsible for restrictions, blocks or account loss imposed by WhatsApp.

The connected number remains yours and your responsibility. We recommend following the best practices to avoid being blocked.

You are the controller of the data of the people you talk to through Hasos (numbers, recordings, transcripts, leads) and are responsible for having a legal basis to process it, for informing your contacts when required (for example, that calls are recorded) and for honoring data subjects’ rights. Hasos processes this data as a processor, on your behalf and according to your instructions, under the Privacy Policy.

• Current plans and prices are listed at hasos.com.br/en#pricing, with monthly or annual billing processed by Stripe: in US dollars (USD) for accounts created through the English site (hasos.com.br/en) and in Brazilian reais (BRL) for accounts created through the Portuguese site. The currency is set at sign-up.
• The 5-day free trial of the Pro plan can be used once per account. A card is required; nothing is charged at the start, and the first charge happens automatically at the end of the trial unless you cancel before then.
• The subscription renews automatically at the end of each period until canceled.
• If a charge fails, the account may be suspended until payment is settled.
• Add-ons (such as the AI Pack and extra numbers) are billed as purchased.
• We may change prices with at least 30 days’ prior notice; the change takes effect from the following period.

You can cancel your subscription at any time under Billing in the dashboard. Canceling stops future charges and the account returns to the Free plan. There are no prorated refunds for periods already paid, except for rights provided by law.

We may also terminate the account for violation of these Terms or for non-payment. After termination, you may request the export or deletion of your data as described in the Privacy Policy.

We work to keep the platform available, and real-time status is at hasos.com.br/status. Unless a service level agreement (SLA) has been contracted in writing, the service is provided “as is”, with no guarantee of uninterrupted operation, and there may be maintenance and outages — including due to changes in WhatsApp or in suppliers.

The platform, the Hasos brand, the software and the documentation belong to Hasos. We grant you a limited, non-exclusive, non-transferable license to use them during your subscription. Your data and content (recordings, contacts, leads) remain yours.

To the maximum extent permitted by law, Hasos is not liable for lost profits, loss of business, indirect damages or for acts of WhatsApp, carriers and third parties, nor for your use of the platform and recordings. Hasos’s total liability is limited to the amount you paid in the 12 months preceding the event giving rise to the claim.

We may update these Terms. Material changes will be communicated by email or in the dashboard with reasonable notice; continued use after they take effect means you accept the new version.

These Terms are governed by the laws of the Federative Republic of Brazil. The courts of Hasos’s domicile are elected as the venue, except for the consumer’s domicile where the law so requires.
