Terms of Service

Effective date: 2026-10-08

These terms are the agreement between you and Zodo for your rc.center account, its plans and the apps sold through it (AI hub and OTPBox). In short: you must be 18 or older, Pro renews every month until you cancel in Manage billing, a cancellation takes effect at the end of the paid month, and OTPBox may not be used to create accounts in bulk on other services.

1. Who we are

rc.center is provided by ZODO SOLUCOES EM TECNOLOGIA LTDA ("Zodo", "we", "us"), a company registered in Brazil under CNPJ 35.403.783/0001-39, with its seat at Av. Felisberto, 22, Vila Nova, Cocal do Sul, SC, 88845-000, Brazil. Contact: contact@zodo.dev.

By creating an account you accept these terms and our Privacy Policy. We record the version you accepted and when. If you do not agree, do not create an account or use the services.

2. The services

• rc.center, the account center at rc.center: your account, sign-in for our apps, two-step verification, plans and billing.
• AI hub (ai-hub.rc.center): a secrets vault for AI sessions. The AI asks for a secret, you approve it, and the secret is delivered end-to-end encrypted to that session.
• OTPBox (otpbox.rc.center): disposable, receive-only e-mail inboxes for AI agents, read over MCP, a REST API or the web.

AI hub is moving its sign-in to rc.center. Until it does, AI hub keeps its own account, and its own terms and privacy policy also apply to it. Where they are more specific about AI hub, they prevail for AI hub; for plans, billing and your rc.center account, these terms prevail.

3. Your account and eligibility

• You must be at least 18 years old and able to enter into a binding contract. The services are not directed to children.
• If you use the services for a company or another organization, you confirm that you may accept these terms on its behalf, and "you" includes it.
• Use a valid e-mail address that you control and confirm it. Apps can only use your account after the address is confirmed.
• Keep your password and your devices safe. We recommend turning on two-step verification and saving your recovery codes. You are responsible for what is done with your account until you tell us it was compromised.
• One account is for one person. Do not share it or sell it.

4. Plans and prices

One subscription per rc.center account covers the apps its plan includes. The current plans are:

• The Pro price is promotional: it is offered for a limited time, without a set end date. If we change it, we tell current subscribers by e-mail before the change applies to them, and the new price applies only from a renewal after that notice. You can cancel before it applies.
• We give at least 30 days' notice of a price increase for an existing subscription.
• You choose US dollars or Brazilian reais on your first checkout. Your billing stays in that currency afterwards; to switch, contact us.
• Prices include applicable taxes.
• Plan limits are part of the plan. When a limit is reached, the app refuses the next action (for example, OTPBox refuses new mail over the monthly quota) instead of charging you more. We never bill usage beyond the plan price.
• We may also offer other plans, including plans that are not shown publicly, by agreement.

5. Billing, renewal and cancellation

• Payments are processed by Stripe. You enter your card on Stripe's page; we never receive or store your card number.
• Pro is a monthly subscription. It is charged when you subscribe and then renews automatically every month, on the same day, until you cancel.
• You can cancel at any time in your account page, under Manage billing (the Stripe customer portal). The cancellation takes effect at the end of the month you already paid: you keep Pro until then and are not charged again. There is no partial refund for the unused part of a month, except as described in Refunds.
• Manage billing also lets you update your card, billing details and tax id, and download your invoices.
• If a renewal payment fails, Stripe retries it. You keep Pro for 7 days counted from the first failed payment. After that, the account works as Free until a payment succeeds, and if Stripe's retries all fail, the subscription ends. Data over the Free limits is not deleted because of this, but the apps stop accepting new data over those limits (OTPBox stops receiving mail; stored messages remain readable until their retention ends).
• Deleting your account cancels your subscription immediately. No refund is issued automatically when you delete your account; you can still ask for one under Refunds.

6. Refunds

• First payment: if you are not satisfied, ask for a refund within 7 days of the first payment of your subscription and we refund it in full. For consumers in Brazil this is the right of withdrawal under the Consumer Protection Code (Law 8.078/1990, art. 49); we offer the same to every customer.
• Renewals are not refunded. Cancel before the renewal date to avoid the next charge.
• If your local consumer law gives you a longer or broader right (for example a right of withdrawal for consumers in the European Union), that right applies.
• If we charge you by mistake, or a service you paid for is unavailable for a long period because of us, we refund the amount concerned.
• To ask for a refund, write to contact@zodo.dev from your account's e-mail address. Refunds go back to the original payment method through Stripe. When a payment is refunded, the subscription ends and the account returns to Free.

7. Promotion and partner codes

• We may issue promotion codes, including partner codes we give to partners to share with their audience. You enter a code in the promotion code field on Stripe's checkout page.
• Each code has its own terms, shown when you get it or at checkout: the discount, how many months it lasts, until when it can be redeemed, and whether it is limited to a first purchase or to a number of uses. Amount-off codes are in US dollars and only work on a US dollar checkout.
• A code that makes the plan free for some months does not require a card. When the free months end, the subscription continues at the regular price. If no card is on file, the first paid renewal fails and the subscription ends after the 7-day grace period described above. You can add a card in Manage billing, or cancel at any time.
• One code per subscription. A redeemed discount stays until its end even if the code later expires.
• Codes have no cash value, cannot be exchanged for money and may not be sold. We may refuse or cancel a discount obtained by fraud, by breaking a code's conditions or by breaking these terms.

8. Acceptable use

You agree not to use rc.center or any of its apps to:

• break the law, or help someone else break it;
• access accounts, data or systems you are not authorized to access, or test, scan or attack the security of the services, except under a written agreement with us;
• overload or disrupt the services, or bypass rate limits, plan limits or other technical restrictions;
• send, store or distribute malware, phishing, spam, or content that infringes the rights of others or that sexually exploits minors;
• resell or provide the services to third parties as a service of your own without our written permission;
• copy, decompile or reverse-engineer the services, except where the law allows it.

If you find a security issue, report it to contact@zodo.dev. We do not take action against good-faith research that respects other users and stops at what is needed to show the issue.

9. OTPBox rules

• OTPBox is receive-only. Inboxes cannot send e-mail, and nothing we run sends e-mail from OTPBox addresses.
• Inboxes are for your own agents and your own accounts, for example to receive sign-up and login codes while you build and test. You must not use OTPBox to create accounts in bulk or automatically on third-party services, or to get around their limits, verification, anti-fraud or anti-abuse measures (for example creating many accounts to collect free trials, bonuses, votes, reviews or referrals).
• You must follow the terms of the services that send mail to your inboxes.
• You must not use OTPBox for fraud, impersonation, harassment, receiving stolen data, or any other illegal purpose.
• You are responsible for the messages your inboxes receive and for having a legitimate reason to receive them. Messages may contain personal data of the people or services that sent them; handle it lawfully.
• Mail over your plan's limits (size, monthly quota, storage or rate) is refused at delivery, so the sender gets an error. It is never accepted and then silently dropped.
• Messages are deleted automatically when your plan's retention ends (30 days on Pro). Keep a copy of anything you need for longer.
• We may suspend an OTPBox account immediately, without prior notice, when we see abuse or a risk to the service, to other users or to third parties. A suspended account stops receiving mail at once. We will tell you why by e-mail, unless the law or an investigation prevents it, and you can contest the suspension by writing to us.

10. AI hub rules

• You are responsible for the secrets you store in AI hub, for having the right to store them, and for the approvals you give. Review every request before approving it and keep grants as short as you can.
• What an AI agent does with a secret you released, and with your machines, is your responsibility and that of the agent's provider.
• Your vault is encrypted with a key derived on your device from your master password. We never receive that password and cannot recover it. If you lose it, the secrets in your vault are lost, and no one, including us, can recover them.

11. Suspension and termination

• You can stop using the services at any time and delete your account in your account page (Delete account). Deletion is immediate and cannot be undone; see the Privacy Policy for what is deleted.
• We may suspend or close an account that breaks these terms, puts the services or other people at risk, or when the law requires it. Unless it is urgent or the law prevents it, we warn you first and give you a chance to fix the problem.
• If we close your account without a breach on your part, we refund the unused part of the current paid month.
• Sections that by their nature should survive (payments due, liability, governing law) survive the end of these terms.

12. Your content and our rights

• Your data and content (secrets, messages, settings) remain yours. You give us only the rights needed to store, process and transmit them to run the services for you, as described in the Privacy Policy.
• The services, their software, design and the names rc.center, AI hub, OTPBox and Zodo belong to us or our licensors. These terms give you the right to use the services, not ownership of them.
• If you send us feedback or suggestions, we may use them without obligation to you.

13. Availability and changes to the services

• We work to keep the services available and secure, but we do not promise that they will be uninterrupted or error-free. There may be maintenance and outages.
• We may change, add or remove features. If we remove a paid feature or close an app that your plan includes, we tell you in advance and, if you prefer to cancel, we refund the unused part of the current paid month.
• We give at least 30 days' notice before closing an app, so you can export or move your data.

14. Warranty and liability

• The services are provided "as is" and "as available", to the extent the law allows. Keep your own copies of anything you cannot afford to lose.
• To the extent the law allows, we are not liable for indirect or consequential damages, lost profits or lost data, and our total liability for any claim related to the services is limited to the amount you paid us in the 12 months before the event that gave rise to it.
• Nothing in these terms limits rights that consumer protection law gives you and that cannot be waived, including under the Brazilian Consumer Protection Code, nor our liability for intent or gross negligence.

15. Changes to these terms

We may update these terms. The effective date at the top shows the current version. We tell you about material changes by e-mail before they take effect. If you do not agree with a change, you can cancel and delete your account before it takes effect; continuing to use the services after that means you accept the new terms.

16. Governing law and disputes

These terms are governed by the laws of Brazil. The courts of the judicial district (comarca) of Criciúma, State of Santa Catarina, Brazil, have jurisdiction. If you are a consumer, you may instead bring a claim in the courts of your own domicile, and nothing here removes the protection that the law of your country of residence gives you as a consumer.

Before going to court, write to us: most problems are solved faster that way. Consumers in Brazil may also use consumidor.gov.br.

These terms are published in English and in Brazilian Portuguese with the same content. If they differ, the Portuguese version prevails for consumers in Brazil and the English version for everyone else.
