Terms of Use

Version 5.0 | Published on October 9, 2026, effective October 24, 2026

1. Who we are and what we offer

CPFHub.io is operated by LIGLU DESENVOLVIMENTO DE SISTEMAS LTDA., registered with CNPJ under No. 10.903.481/0001-07, headquartered in the state of Santa Catarina, Brazil (“CPFHub.io”, “we”).

We offer lookup and validation of registration data by CPF, through the API, the dashboard and the MCP server. The service is built for companies and professionals who use the lookup in their own products and processes (B2B).

By creating an account or using the service, you (“Customer”) agree to these Terms and confirm that the information in your signup is true. If you sign up on behalf of a company, you confirm that you are authorized to do so.

2. What CPFHub.io is for

CPFHub.io exists to help companies confirm that a person is who they say they are. This also protects the CPF holder, because it makes it harder for someone else to use their data to open accounts, sign up for services or impersonate them. Processing follows the LGPD (Brazil's data protection law), based on legitimate interest in secure relationships and fraud prevention. Some examples of use:

• signup validation and customer onboarding (KYC),
• preventing fraud and the use of another person's CPF,
• authentication and data confirmation during customer service,
• risk analysis in sales, contracts, rentals and credit,
• updating and cleaning up records you already have,
• meeting the legal and regulatory obligations of your industry,
• collections, legal proceedings and the defense of rights,
• age verification, combined with a way to confirm that the user is the owner of the CPF.

Marketing, prospecting and building contact lists are outside the scope of the service.

Not sure whether your case fits? Talk to us before you start. You will get the answer in writing.

3. Your responsibilities

When you use CPFHub.io, you:

• are the controller, under the LGPD (Law 13.709/2018, Brazil's data protection law), of the data you receive, and use each lookup with a legitimate purpose and an appropriate legal basis,
• tell your users, in your privacy policy, that their registration data may be verified with identity validation and fraud prevention providers,
• keep the results only for as long as your purpose requires, with appropriate security,
• keep your API keys on your server and are responsible for how they are used,
• keep your account and billing details up to date.

4. Integration, partners and resale

4.1. Integration into your product. You can integrate the API into your software, system or SaaS and offer the lookup to your own customers, for example as a “fetch data by CPF” feature in a signup form. This does not require any additional authorization.

4.2. Partner Program. Partners are welcome to bring the lookup to their customers. The formats are:

• wholesale credits: the partner buys credits on special terms and offers the lookup at the price they choose,
• end customer account: each of the partner's customers has their own CPFHub.io account, and the partner takes care of the integration,
• private label (white label): the partner offers the lookup under their own brand.

Participation is set up through a simple agreement or a written confirmation, and an email is enough. Contact the sales team at parcerias@cpfhub.io.

4.3. Rules for integrators and partners. Anyone who offers the lookup to third parties:

• passes on to their customers, through their own contract or terms, rules equivalent to these Terms regarding purpose and legal basis,
• can identify which customer made each lookup, in case CPFHub.io needs this information to respond to a data subject or an authority,
• under private label, states in their privacy policy that they use identity validation providers,
• keeps the API keys on their own server.

The partner offers access to the lookup. Storing results to build and sell databases or lists of personal data is not part of the program.

5. Availability and support

• Availability: we aim to maintain the monthly availability stated for your plan on the pricing page (https://www.cpfhub.io/precos) or in your contract. Scheduled maintenance is announced at least 24 hours in advance.
• API changes: we give 30 days' notice before changing or discontinuing an endpoint, except when required by law, in cases of force majeure or for security risks.
• Support: an automated assistant on WhatsApp, 24 hours a day, 7 days a week. Cases that need review go to the specialized team, available on business days from 9 a.m. to 6 p.m. (Brasília time).

6. Real-Time Lookup at Receita Federal

The Real-Time Lookup is an optional service that returns, at the time of the call, the result of the public CPF registration status lookup at Receita Federal (Brazil's federal tax authority): name, registration status, indication of death (when applicable), control code and proof of the lookup.

• The lookup requires the data subject's date of birth, provided by you, and you confirm that you obtained it lawfully.
• The proof shows what Receita Federal displayed at that moment and can be checked on the Receita Federal website through the validation link. It is not a certificate.
• The fields and requirements of the lookup are set by Receita Federal and may change. When that happens, we adjust the service and let you know.
• CPFHub.io is not an official, accredited or certified partner of Serpro or Receita Federal, and the result must not be presented that way.
• The cost in credits is listed on the pricing page.

7. Plans, payment and cancellation

• Paid plans work as a monthly subscription, renewed automatically each cycle.
• You can cancel at any time from the dashboard, with no fee and no prior notice. Access continues until the end of the period already paid, and there are no further subscription charges, apart from any overage used in that period.
• Credits are available as soon as the plan is purchased, and each lookup has a processing cost with the data sources. For this reason, the amount paid for a cycle is non-refundable, and unused credits are not converted into cash.
• If CPFHub.io decides to end the service for you without any breach of these Terms, we give you 30 days' notice and refund the proportional amount for the unused period.

8. When we may suspend or close an account

We always prefer to talk first:

• Use outside these Terms: if we notice a use that does not match these Terms, we let you know and give you 5 business days to explain or adjust. If the problem continues, we may close the account.
• Serious risk: in case of signs of fraud, a security incident, use of the account by third parties without authorization or an order from an authority, we may suspend access right away to protect you, the data subjects and the platform. We explain the reason afterwards, and you can send us your clarifications.
• Payment: non-payment may suspend access until it is settled.
• New signups: we may decline to open accounts based on risk and security criteria.

When an account is closed because of a breach of these Terms, amounts already paid are not refunded.

9. Personal data and LGPD

• CPFHub.io as controller: of your account data and of our validation database.
• CPFHub.io as processor: when we run a lookup you send, following your instructions.
• You as controller: of the data you receive and of how you use it.

Verified lookup results may be used by CPFHub.io to keep the validation database correct and up to date, always for the purposes in section 2. Security incidents involving service data are reported between the parties within 72 hours. The details are in the Privacy Policy.

10. Liability

• We use data licensed from private providers and official public sources, with quality controls. Results reflect the sources at the time of the lookup and support your decision, without replacing your own verification processes.
• CPFHub.io is not liable for business decisions made based on the lookups, for indirect damages or lost profits, or for failures caused by force majeure or the unavailability of external sources.
• CPFHub.io's total liability is limited to the amount you paid in the 12 months before the event, except in cases of willful misconduct or gross negligence.
• If the use of the service by you or your customers, in breach of these Terms or the law, leads to a complaint, fine or judgment against CPFHub.io, you will reimburse the corresponding amounts.

11. Intellectual property

The API, the documentation, the technology and the CPFHub.io brand belong to CPFHub.io. While your account is active, you have a license to use the service for the purposes of these Terms, including the integration and partnership formats in section 4.

12. General provisions

• Reading these Terms: these Terms should be read in light of their purpose: to allow legitimate and safe use of the CPF lookup.
• Changes: we may update these Terms. Each new version is published on this page at least 15 days before it takes effect, and relevant changes are also announced by email or in the dashboard. We recommend checking this page periodically. Continuing to use the service after the effective date means you accept the new version.
• Law and venue: these Terms follow Brazilian law. The courts of Florianópolis, SC, Brazil, are the chosen venue.
• Validity: if any clause is held invalid, the others remain in effect.
