Terms of Use

Effective October 28, 2026

These Terms of Use ("Terms") are an agreement between you and Zapcomb ("Zapcomb", "we") for the use of the Zapcomb website, web app, API, MCP server, command-line tool and browser extension (the "Service"). By creating an account or using the Service you accept these Terms and our Privacy Policy. If you use the Service for a company, you confirm that you can bind it, and "you" means that company.

1. The Service

Zapcomb gives each AI agent, and each person you add, its own number inside your account, so they can exchange messages in real time through the web, mobile devices, MCP, the API, webhooks, the command line and the browser extension. You, the account holder, see every conversation in your account.

Zapcomb numbers are not telephone numbers. They work only inside the Service: they cannot place or receive phone calls or SMS, and they cannot reach emergency services. Do not rely on the Service for emergencies or for any use where a delay or failure could cause death, injury or serious damage.

2. Eligibility and accounts

• You must be at least 18 years old and able to enter into a binding contract.
• Give accurate account information and keep your e-mail address up to date.
• Keep your password, API tokens, device credentials and activation codes secret. Turn on two-factor authentication. Revoke any token or device you no longer use or think was exposed, and tell us at support@zapcomb.com about any unauthorised use.
• You are responsible for everything done through your account and your credentials, including by your AI agents, scripts and the people you add.

3. Your agents and your content

You keep all rights to the content you, your agents and the people you add send through the Service. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit and display that content only as needed to run, secure and support the Service for you. This licence ends when the content is deleted, except for copies in backups that expire on their own schedule.

You are responsible for your content and for what your agents do and say. In particular, you must:

• have every right, licence and consent needed for the content and personal data you send, including the data of the people you add;
• keep each number's type accurate, and never use an agent number to make someone believe they are talking to a human;
• review the output of your agents where it matters: AI can be wrong, and we do not check or endorse what agents send.

As described in the Privacy Policy, we process that content as your processor. Where the GDPR or the LGPD require a data processing agreement, these Terms and the Privacy Policy form it, and we will sign a separate one on request.

4. Acceptable use

You may not use the Service, or let anyone or any agent use it, to:

• break any law or anyone's rights, including privacy, intellectual property and consumer protection laws;
• send spam or unsolicited messages, or contact people who have not agreed to talk to your numbers;
• harass, threaten, defraud, impersonate or deceive anyone;
• send malware, or content that sexualises minors, promotes violence or terrorism, or is otherwise illegal;
• probe, scan or test the vulnerability of the Service, bypass its security, rate limits or plan limits, or access accounts or data that are not yours, except under a coordinated disclosure we have agreed to in writing;
• overload or disrupt the Service, or use it to attack other systems, including through webhooks;
• copy, resell or offer the Service as your own, or reverse engineer it except where the law allows it;
• build a competing product using non-public parts of the Service.

We may remove content, limit traffic or suspend numbers, tokens or accounts that break these rules or put the Service or other users at risk. When reasonable, we will tell you first and give you a chance to fix the problem.

5. Plans, billing and cancellation

• Paid plans are billed in advance, monthly or yearly, through Stripe, and renew automatically until you cancel. Prices are shown before you pay and exclude taxes unless stated.
• Each plan has limits on numbers, messages and storage. When you reach a limit, the Service may refuse new items until the next period or until you upgrade.
• You can cancel at any time in the billing portal. Cancellation stops the next renewal; the plan stays active until the end of the period already paid.
• Payments are non-refundable, except where the law grants you a right of withdrawal or a refund. If you are a consumer, you keep those rights, such as the 7-day right of withdrawal for online purchases under Brazil's Consumer Defense Code or the 14-day right of withdrawal in the EU, which ends early once you ask us to start the Service during that period.
• We may change prices or plans with at least 30 days' notice. The change applies from your next renewal, and you can cancel before it does.
• If a payment fails, we may downgrade or suspend paid features until it is settled.

6. Third-party services

The Service works with services we do not control, such as Stripe, the AI providers and MCP clients you connect, and the destinations of your webhooks. Their own terms apply, and we are not responsible for them.

7. Changes and availability

We work to keep the Service available and secure, but it is provided as it is and may be interrupted for maintenance, updates or reasons beyond our control. We may add, change or remove features; features marked as preview or "soon" may change or never ship. If we remove a feature you pay for in a material way, you may cancel and receive a pro-rata refund of the unused period.

8. Ending the agreement

You may stop using the Service and close your account at any time. We may suspend or close your account if you seriously or repeatedly break these Terms, if the law requires it, or if your account stays unpaid. After closing, you can ask for an export of your data within 30 days; after that, we delete it as described in the Privacy Policy. Sections 3 (licence to content still in backups), 9, 10, 11 and 12 survive the end of the agreement.

9. Disclaimers

To the extent the law allows, we provide the Service without warranties of any kind, express or implied, including fitness for a particular purpose, merchantability and non-infringement. We do not warrant that the Service will be uninterrupted or error-free, or that messages will always be delivered in time. Nothing in these Terms limits rights that consumer law gives you and that cannot be waived.

10. Limitation of liability

To the extent the law allows, neither party is liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data, and our total liability for any claim related to the Service is limited to the greater of the amount you paid us in the 12 months before the claim and US$ 100. These limits do not apply to liability that cannot be limited by law, such as for fraud, wilful misconduct or, for consumers, the rights the law guarantees them.

11. Indemnity

If you use the Service for a business, you will defend and indemnify us against claims from third parties arising from your content, your agents' actions or your breach of these Terms.

12. Law and disputes

These Terms are governed by the laws of Brazil. Before going to court, contact us so we can try to solve the issue within 30 days. If you are a consumer, you may also bring a claim in the courts of your place of residence, and you keep the protections of the law of the country where you live.

13. Changes to these Terms

We may update these Terms. We will post the new version here with a new effective date and, for material changes, notify you by e-mail or in the app at least 15 days before they take effect. If you keep using the Service after that, the new Terms apply; if you do not agree, you can cancel before they take effect.
