These Terms of Use govern the relationship between IJA SOLUÇÕES LTDA, registered under CNPJ No. 65.014.643/0001-30, headquartered at Rua Capitão José da Luz, 137, room 0203, Edifício Cervantes Cais 202, Coelhos, Recife, PE, ZIP 50070-540, Brazil, hereinafter "Vexum", and the law firm that contracts and uses the Vexum system, hereinafter "Client".

These Terms apply to use of the system by the Client and its authorized users. They do not apply to end data subjects (clients of the Client who receive messages through the system), who are not users of the system and whose relationship with personal data processing is governed by the Vexum Privacy Policy and the Data Deletion Instructions, published separately.

1. SUBJECT MATTER

1.1. Vexum provides the Client with a client communication and payment-reminder system operating over WhatsApp, comprising: (i) automated sending of due-date reminders and payment status notifications, on the Client's behalf, to the clients with outstanding balances it designates, relating to pre-existing agreements between the Client and those clients; (ii) receipt and organization of the replies sent by those recipients; and (iii) a service dashboard, so the Client's team can view and reply to those conversations.

1.2. The technical, commercial and financial details of the service, including prices, payment terms, service level and specific term, are set out in the service agreement executed between the Parties, which prevails over these Terms in the event of conflict relating to those commercial conditions.

1.3. Use of the system depends on the existence of an active WhatsApp Business account, owned by the Client itself, linked to the WhatsApp Business Platform operated by Meta Platforms, Inc. Vexum integrates directly with Meta's WhatsApp Business Platform, with no technical intermediary, but does not own the Client's account and does not control it beyond what is necessary to provide the contracted service.

2. REGISTRATION AND ACCESS

2.1. The Client must provide true, complete and up-to-date information at the time of registration, and is responsible for keeping it so throughout the entire term of the relationship.

2.2. The Client is responsible for maintaining the confidentiality of the dashboard access credentials assigned to its users, and for all activity carried out using those credentials. Vexum must be notified immediately in the event of suspected unauthorized use.

2.3. Vexum may suspend a specific user's access at the Client's own request, or suspend the Client's access to the system, upon prior notice, in the event of breach of these Terms, of the service agreement, or of use of the system in a manner incompatible with applicable law.

3. CLIENT OBLIGATIONS

3.1. The Client is solely responsible for defining the content, purpose, frequency and recipients of the messages sent through the system, and represents that it has an adequate legal basis, under Law No. 13.709/2018 (LGPD), for processing the personal data of the recipients of those messages, of which it is the controller.

3.1-A. In addition to the legal basis required under the LGPD, the Client represents that it has obtained from recipients the prior opt-in required by Section 1 of Meta Platforms, Inc.'s WhatsApp Business Messaging Policy, consisting of the recipient voluntarily providing their phone number and confirming that they wish to receive messages from the Client through this channel. The Client is solely responsible for obtaining, recording and evidencing such opt-in, and for promptly honoring any opt-out requests made by recipients.

3.2. The Client undertakes to use the system exclusively for lawful purposes, and in compliance with: applicable personal data protection legislation; the Consumer Protection Code (Law No. 8.078/1990), in particular the prohibitions on debt recovery practices that expose the consumer to ridicule or embarrassment, or that subject the consumer to threat, coercion or false, incorrect or misleading statements (articles 42 and 71); the commercial and messaging policies of Meta Platforms, Inc. applicable to the WhatsApp Business Platform; and, where applicable to the specific case, the rules of the Brazilian Bar Association Statute (Law No. 8.906/1994) relating to professional privilege and to advertising and client solicitation.

3.3. The Client is solely responsible, before the recipients of the messages and before third parties, for the content of the communications sent through the system, including any incorrect information about amounts, due dates or identification of the agreement or the outstanding obligation.

3.4. The Client undertakes to respond, within the statutory period, to data subject requests relating to the exercise of the rights provided for in article 18 of the LGPD, and to cooperate with Vexum whenever Vexum forwards a request received directly from an end data subject, under the Vexum Data Deletion Instructions.

3.5. The Client is responsible for keeping its WhatsApp Business account in compliance with Meta's rules, including maintaining a valid payment method with Meta for the message traffic generated by use of the system, where required by the platform itself.

4. VEXUM OBLIGATIONS

4.1. Vexum undertakes to operate the system with reasonable technical care, to process end data subjects' personal data exclusively in accordance with the Client's instructions and for the purpose described in Clause 1, in its capacity as processor under article 39 of the LGPD, and not to use that data for its own purposes.

4.2. Vexum undertakes to adopt technical and administrative information security measures appropriate to the nature of the data processed, as described in the Vexum Privacy Policy.

4.3. Vexum undertakes to notify the Client, without undue delay, of any security incident that may affect the data processed in connection with the service, so that the Client can meet its own obligations as controller before the National Data Protection Authority and data subjects.

4.4. Vexum does not warrant uninterrupted availability of the system, given its dependence on third-party infrastructure, in particular the WhatsApp Business Platform operated by Meta Platforms, Inc., whose availability and usage rules are outside Vexum's control.

5. INTELLECTUAL PROPERTY

5.1. The Vexum system, including its software, interface, brand, layout and other associated intellectual property elements, belongs to Vexum or its licensors, and no provision of these Terms transfers to the Client any right over those assets beyond the right to use the system during the term of the contract.

5.2. The data entered by the Client into the system, and the data processed on its behalf relating to end data subjects, remains owned by the Client and by the respective data subjects, as applicable, and Vexum acquires no ownership right over it.

6. LIMITATION OF LIABILITY

6.1. Vexum is not liable for decisions on content, tone, frequency or recipient of the messages sent by the Client through the system, nor for any consequences arising from those decisions, except where Vexum has failed to comply with a lawful instruction from the Client or with an obligation of its own under these Terms.

6.2. Vexum is not liable for suspension, blocking, quality rating restriction or banning of the Client's WhatsApp Business account by Meta Platforms, Inc., where such action arises from conduct of the Client itself, of its users, or from breach of Meta's policies.

6.3. Except in cases of willful misconduct, gross negligence, or liability that the law does not permit to be limited, Vexum's civil liability toward the Client arising from these Terms is limited to the amount actually paid by the Client to Vexum in the 12 (twelve) months preceding the event giving rise to the damage.

6.4. Without prejudice to any joint and several liability attributed to Vexum and the Client before data subjects or before the National Data Protection Authority under article 42, paragraph 1, of the LGPD, the Parties undertake to reimburse each other, in proportion to the fault of each, for fines, indemnities or other administrative or judicial penalties that either of them is required to bear by reason of conduct demonstrably attributable to the other, including failure to comply with a lawful instruction, with an information security obligation, or with a processing purpose defined in these Terms and in the Vexum Privacy Policy.

7. TERM AND TERMINATION

7.1. These Terms remain in force for as long as the contractual relationship between the Parties lasts, as defined in the service agreement.

7.2. Either Party may terminate the relationship under the terms and notice periods set out in the service agreement. Once the relationship ends, the data retention and deletion rules described in the Vexum Privacy Policy apply.

7.3. Once the contractual relationship ends, Vexum shall make available to the Client, upon request made within 30 (thirty) days from termination, an export file containing the data and the conversation history recorded in the system during the term of the engagement, in a structured and commonly readable format, so that the Client can meet its own obligations as controller of that data. After that period, the retention and deletion rules described in the Vexum Privacy Policy apply.

8. CHANGES TO THESE TERMS

8.1. Vexum may amend these Terms to reflect changes in the system, in applicable legislation, or in the policies of partners necessary to provide the service, such as Meta Platforms, Inc. Material changes will be communicated to the Client with reasonable prior notice, and continued use of the system after that communication constitutes agreement with the new terms.

9. GENERAL PROVISIONS AND JURISDICTION

9.1. These Terms, the Vexum Privacy Policy and the Vexum Data Deletion Instructions, together with the service agreement executed between the Parties, form the set of rules applicable to the relationship between Vexum and the Client. In the event of conflict between these Terms and the service agreement regarding specific commercial conditions, the service agreement prevails.

9.2. The courts of the Judicial District of Recife, State of Pernambuco, Brazil, are elected to settle any disputes arising from these Terms, with express waiver of any other, however privileged.
