Terms of Service

Last updated: August 1, 2026

These Terms of Service (“Terms”) govern access to and use of the website rubrix.lat, the Rubrix platform and its related APIs, features and services (collectively, the “Platform”), made available by RUBRIX DESENVOLVIMENTO DE SOFTWARE PARA DOCUMENTOS ELETRÔNICOS LTDA., a Brazilian limited liability company enrolled with the CNPJ/MF under No. 67.021.890/0001-99, headquartered in Florianópolis, Santa Catarina, Brazil (“Rubrix”, “we”, “us”).

By accessing or using the Platform, you represent that you have read, understood and fully accepted these Terms and our Privacy Policy. If you do not agree with these Terms, do not use the Platform.

1. Acceptance of the Terms

1.1. Use of the Platform, with or without registration, implies full acceptance of these Terms. Acceptance may also be expressed by clicking an agreement button, signing a document through the Platform or any other form of electronic expression of intent.

1.2. If you use the Platform on behalf of a legal entity, you represent that you have the authority to bind it to these Terms, and references to “you” or “User” shall include that legal entity.

1.3. Corporate customers may enter into a specific services agreement with Rubrix (such as a Master Services Agreement and the corresponding contracted plan). In the event of conflict between these Terms and the specific agreement, the specific agreement shall prevail with respect to commercial conditions and any other matters expressly governed by it.

2. Definitions

  • “Electronic Document”: any document, contract, form, statement, term, attachment or other electronic file submitted to the Platform for creation, sending, signing, tracking or management.
  • “Envelope”: the processing unit used to send an Electronic Document to one or more Signers within the same signature flow.
  • “User”: any person who accesses or uses the Platform, with or without registration, including document senders and Signers.
  • “Signer”: the individual or legal entity designated to sign or express agreement with an Electronic Document through the Platform.
  • “Access Credentials”: identifiers, passwords, keys, tokens, certificates or other authentication mechanisms used to access the Platform.
  • “FinanceID”: Rubrix's patented technology that uses the identity confirmation performed by a financial institution in the context of an instant payment transaction (such as Pix) to identify the Signer and enable the issuance of a single-use digital certificate.
  • “Rubrix CA”: the Certificate Authority operated by Rubrix, responsible for issuing single-use digital certificates within signature flows.
  • “Trust Service Providers”: certificate authorities, identity providers and other third parties providing digital certification, authentication or timestamping services integrated with the Platform.
  • “API”: the application programming interface made available by Rubrix for integrating the Platform with third-party systems.
  • “LGPD”: Brazilian Law No. 13,709/2018 (General Personal Data Protection Law), as amended, and its subsequent regulations.

3. Nature of the Services

3.1. Rubrix acts as a technology infrastructure provider for electronic and digital signatures, offering a platform for managing the lifecycle of electronic documents, orchestrating signature flows and integrating with Trust Service Providers and digital certification services.

3.2. You acknowledge and agree that Rubrix:

  • is not a party to the documents, contracts, statements or other legal acts executed through the Platform;
  • does not participate in the negotiation, formation of intent or expression of consent of the parties involved in documents submitted to the Platform;
  • does not validate, review, alter or approve the content of submitted documents, nor is it responsible for their legitimacy, authenticity, accuracy, integrity, lawfulness or fitness for the intended purposes;
  • does not act as attorney-in-fact, representative, intermediary or agent of any User before third parties;
  • does not hold custody of third parties' private cryptographic keys, except as expressly provided for in the contracted modality and under applicable law;
  • does not provide legal, notarial, registry, consulting or audit services.

4. Registration, Account and Credentials

4.1. No account is required to sign a document as a Signer: simply access the link received and complete identity verification through one of the available methods. Use without an account is controlled by national identifier (such as CPF in Brazil, RUT in Chile and equivalents in other countries).

4.2. Registration is required to create Envelopes and send Electronic Documents for signature. When registering, you undertake to provide true, complete and up-to-date information and to keep it so throughout your use of the Platform.

4.3. Access Credentials are personal and non-transferable. You are responsible for all activities carried out with your Access Credentials and must immediately notify Rubrix of any suspected unauthorized access or security compromise.

4.4. Rubrix may refuse, suspend or cancel registrations that violate these Terms or applicable law, or that show signs of fraud.

5. Signatures and Legal Validity

5.1. The Platform offers different signature methods, subject to availability: digital signature with a qualified certificate (including cloud certificates), signature with a single-use certificate issued by the Rubrix CA upon identification via FinanceID or other identity providers (such as gov.br), and other methods that may be offered.

5.2. In Brazil, electronic and digital signatures are supported, among others, by Provisional Measure No. 2,200-2/2001 (including its art. 10, § 2, which recognizes the validity of signatures outside the ICP-Brasil standard when accepted by the parties), Law No. 14,063/2020 and the Civil Code. In other jurisdictions, the corresponding local rules apply — for example, the eIDAS Regulation (EU) No. 910/2014 in the European Union, Law No. 19,799 in Chile, Law No. 25,506 in Argentina, Law No. 527/1999 in Colombia and equivalent rules in the other countries where the Platform operates.

5.3. Each signature made through the Platform embeds a digital certificate into the PDF file itself, allowing authenticity and integrity to be verified in any compatible reader, independently of Rubrix.

5.4. The Platform records an audit trail of signature flows, including events, timestamps, IP addresses and authentication evidence, which may be used as evidence.

5.5. It is solely your responsibility to select the signature method suitable for your needs and for the legal, regulatory or contractual requirements applicable to each act or legal transaction. Rubrix does not warrant that the chosen method will be sufficient to meet any specific requirement of form, validity, enforceability or evidentiary admissibility in a given jurisdiction.

6. FinanceID and Single-Use Certificates

6.1. In the FinanceID flow, the Signer makes an instant payment transaction of a symbolic amount (for example, a Pix transfer of R$ 0.01) from an account held in their own name. The identity confirmation performed by the financial institution (banking KYC) is used to verify the Signer's identity.

6.2. Once identity is confirmed, the Rubrix CA issues a single-use digital certificate in the Signer's name, used exclusively to sign the Electronic Document of that flow.

6.3. The transaction amount is intended exclusively for identity verification, does not constitute payment for Rubrix's services and is non-refundable.

6.4. By using FinanceID, you represent that the account used is held in your own name and authorize the processing of the identification data returned by the financial institution for the purposes described in the Privacy Policy.

7. Documents and Temporary Storage

7.1. The Platform is not a document storage or archiving service. Electronic Documents remain available for the time needed to complete the signature flow and are automatically removed from the servers after the applicable period.

7.2. We recommend that you download the signed document as soon as the flow is completed. The signed PDF remains valid and verifiable independently of the Platform, as the digital certificate is embedded in the file itself.

7.3. Rubrix is not responsible for the loss of documents not downloaded within the availability period indicated on the Platform.

8. User Responsibilities

8.1. When using the Platform, you undertake to:

  • use the Platform exclusively for lawful purposes and in compliance with these Terms and applicable law;
  • ensure that the documents, data and information submitted to the Platform are lawful, complete and accurate, and that you hold all rights, authorizations, legal bases and consents required for their processing and sharing — including with respect to the personal data of the Signers you designate;
  • be responsible for the validity, content, purpose, performance and legal effects of the documents and transactions executed through the Platform;
  • keep your Access Credentials confidential;
  • notify Rubrix, without undue delay, of any security incident, misuse of credentials or unauthorized use of the Platform of which you become aware;
  • be solely responsible for the relationship with Signers and other third parties involved in your documents.

9. Acceptable Use and Prohibited Conduct

9.1. Users are prohibited, directly or through third parties, from:

  • using the Platform to carry out unlawful or fraudulent acts, or acts that violate third-party rights;
  • signing documents on behalf of third parties without authority to do so, or using identification means belonging to someone else;
  • violating or attempting to violate the security, integrity, availability or operation of the Platform;
  • circumventing, disabling or interfering with authentication, access control, usage limitation, monitoring or security mechanisms;
  • using bots, scripts or automated tools that may compromise the performance, stability or security of the Platform, except for expressly authorized integrations and APIs;
  • transmitting, storing or processing unlawful content or content that violates third-party rights;
  • copying, modifying, adapting or creating derivative works of the Platform, or reverse engineering, decompiling or disassembling it, except where such right cannot be waived under applicable law;
  • making the Platform available to, reselling it to or sublicensing it to third parties without Rubrix's express authorization;
  • using the Platform to develop a competing product or service.

9.2. Violation of this clause may result in suspension or termination of access, without prejudice to any other applicable legal measures.

10. Plans, Prices and Payment

10.1. The Platform may offer free and paid features. Amounts, usage limits, consumption metrics (such as Envelopes or API calls) and billing methods shall be those set out in the contracted plan, commercial proposal or the conditions published on the Platform at the time of contracting.

10.2. Unless otherwise provided, amounts do not include taxes that must be highlighted or added to the price, nor third-party services contracted directly by you.

10.3. For contracts governed by Brazilian law, amounts may be adjusted annually according to the accumulated variation of the IPCA/IBGE index or any index that may replace it.

10.4. Late payment shall subject the amounts due to a late-payment penalty of 2% (two percent), default interest of 1% (one percent) per month calculated pro rata die and monetary restatement by the IPCA index, without prejudice to the possibility of suspension of the services upon prior notice.

10.5. The conditions of free plans may be changed or discontinued by Rubrix at any time, upon notice on the Platform.

11. API, Integrations and Third-Party Services

11.1. Use of the API is subject to the technical documentation available at rubrix.lat/docs and to the applicable technical and commercial limits.

11.2. The Platform may integrate with third-party services, including Trust Service Providers, identity providers, financial institutions and payment schemes, cloud computing providers, communication services and other technology solutions. Such services remain subject to the conditions established by their respective providers.

11.3. Rubrix is not responsible for the availability, performance, continuity, security or policies of third-party services, nor for unavailability or failures exclusively attributable to such services.

12. Intellectual Property

12.2. Rubrix grants you a limited, non-exclusive, non-transferable, non-sublicensable and revocable license to use the Platform, exclusively to use the services as set out in these Terms. Nothing in these Terms implies an assignment or transfer of intellectual property rights.

12.3. The documents, content, trademarks, data and other materials you submit to the Platform remain your property; Rubrix is granted only the rights necessary to provide the services.

12.4. Suggestions, comments or improvement proposals sent to Rubrix (“Feedback”) may be freely used by Rubrix to evolve the Platform, without any obligation of payment or attribution.

13. Privacy and Data Protection

13.1. The processing of personal data within the Platform is governed by our Privacy Policy, which forms an integral part of these Terms.

13.2. With respect to personal data entered into the Platform by Users in the context of their own documents and signature flows, the User acts, as a rule, as controller and Rubrix as processor, under the LGPD and equivalent laws. Rubrix acts as controller with respect to data processed for its own purposes, such as account administration, billing, security and fraud prevention.

13.3. Each party is responsible for complying with the data protection obligations assigned to it by applicable law. The User represents that they hold an adequate legal basis for processing the personal data they enter into the Platform.

14. Confidentiality

14.1. The parties undertake to keep confidential the confidential information to which they have access as a result of using the Platform, using it exclusively for the purposes set out in these Terms, except with the prior written authorization of the owner or as required by law, regulation or order of a competent authority.

14.2. Confidentiality obligations remain in force even after termination of use of the Platform.

15. Availability, Support and Maintenance

15.1. Rubrix will use commercially reasonable efforts to maintain the availability, security and operation of the Platform, and may carry out scheduled or emergency maintenance whenever necessary. Whenever reasonably possible, scheduled maintenance with potentially significant impact will be communicated in advance.

15.2. The following do not constitute a breach of these Terms: unavailability resulting from scheduled or emergency maintenance; acts of God or force majeure; failures of third-party services, networks or infrastructure; cyberattacks and security events requiring containment; or acts and omissions of the User.

15.3. Support is provided through the channels indicated on the Platform. Specific service levels (SLA) apply only when expressly provided for in the corresponding plan or agreement.

16. Disclaimer of Warranties

16.1. Except as expressly provided in these Terms and for non-waivable statutory warranties, the Platform is provided “as is”, without warranties of any kind, express or implied, including warranties of uninterrupted availability, absence of errors, fitness for a particular purpose or compatibility with non-approved third-party systems.

16.2. Rubrix does not warrant the uninterrupted operation of communication networks, internet providers, cloud computing services, digital certification services, authentication providers, payment schemes or any other external services outside its direct control.

17. Limitation of Liability

17.1. Rubrix shall be liable exclusively for direct damages demonstrably caused by breach of its obligations, subject to the limits of this clause and applicable law.

17.2. Rubrix's total liability, regardless of the legal basis invoked, is limited to the amount actually paid by you to Rubrix in the 12 (twelve) months immediately preceding the event giving rise to the claim — or, in the case of free use, to the maximum limits permitted by applicable law.

17.3. In no event shall Rubrix be liable for indirect damages, loss of profits, loss of revenue, loss of business opportunities, loss of data not attributable to Rubrix, reputational damage or any consequential losses, even if informed of the possibility of their occurrence.

17.4. The limitations in this clause do not apply in cases of willful misconduct or fraud, nor where the limitation of liability is prohibited by law — including rights guaranteed by consumer protection rules, where applicable.

18. Indemnification

18.1. You agree to indemnify and hold Rubrix harmless from losses, damages, awards, costs, expenses and attorneys' fees arising from third-party claims originating from: (a) the content of the documents and information you enter into the Platform; (b) the absence of a legal basis for the processing of personal data under your responsibility; (c) use of the Platform in breach of these Terms or applicable law; or (d) violation of third-party rights caused by your acts or omissions.

19. Suspension and Termination

19.1. Rubrix may suspend, in whole or in part, your access to the Platform in the event of: violation of these Terms; risk to the security, stability or integrity of the Platform or third parties; suspected fraud; default, upon prior notice; or legal requirement or order of a competent authority.

19.2. You may close your account at any time through the channels made available by Rubrix. Termination does not release you from paying amounts due up to the date it takes effect.

19.3. Upon termination of access, the license of use is automatically extinguished and data and documents will be deleted or retained in accordance with the Privacy Policy and applicable law. Clauses that by their nature should remain in force survive termination, including those on intellectual property, confidentiality, limitation of liability and dispute resolution.

20. Changes to these Terms

20.1. Rubrix may update these Terms from time to time. Material changes will be communicated at least 15 (fifteen) days in advance, through the Platform or the contact channels provided.

20.2. Changes required to comply with legislation, decisions of competent authorities, information security requirements, fraud prevention or operational continuity may take effect immediately, upon notice.

21.1. These Terms do not create any corporate, employment, association, representation, franchise, agency or joint venture relationship between you and Rubrix.

21.2. You may not assign or transfer the rights and obligations arising from these Terms without Rubrix's prior written authorization. Rubrix may assign its contractual position to companies of its economic group or as a result of corporate reorganization, provided the obligations undertaken are preserved.

21.3. Tolerance of any breach shall not constitute novation or waiver of rights. The invalidity of any provision shall not affect the remaining provisions, which shall remain in full force.

21.4. Neither party shall be deemed in default due to non-performance resulting from acts of God or force majeure, for as long as their effects persist.
