OneClick WhatsApp Business Platform — Terms of Service

These Terms of Service ("Terms", "Terms of Service" or "Agreement") govern the access to and use of the OneClick WhatsApp Business Platform and related services provided through whatsapp.oneclick.co.tz ("OneClick", "Platform", "Service", "we", "us" or "our") by iMartGroup Ltd, a company incorporated and operating under the laws of the United Republic of Tanzania.

By registering for an account, accessing the Platform, connecting a WhatsApp Business Account, purchasing or using any OneClick WhatsApp Business service, or otherwise using the Service, the business customer ("Client", "you" or "your") agrees to be legally bound by these Terms.

If you are using the Platform on behalf of a company, organisation or other legal entity, you represent that you have authority to bind that entity to these Terms.

These Terms should be read together with our Privacy Policy and any applicable service order, pricing schedule, commercial agreement or other terms specifically agreed between OneClick and the Client.

1. About OneClick

OneClick is a business messaging platform operated by iMartGroup Ltd that enables businesses and organisations to use WhatsApp Business messaging services for customer communication, customer support, service notifications, authentication and OTP, transactional notifications, approved marketing communications, message management and business WhatsApp account management.

OneClick provides the platform and related services through which Clients may connect and manage their approved WhatsApp Business accounts and communicate with their customers.

OneClick is not WhatsApp and is not the owner or operator of the WhatsApp consumer messaging service.

WhatsApp and Meta services are provided by their respective entities and are subject to applicable Meta and WhatsApp terms, policies, documentation and requirements.

Where applicable, the Client's use of WhatsApp through OneClick is also subject to the terms, policies and requirements imposed by Meta and WhatsApp, including applicable WhatsApp Business terms, WhatsApp Business Solution Terms, WhatsApp Business Messaging Policy, WhatsApp Messaging Guidelines and other applicable policies or documentation.

2. Acceptance of these Terms

By using OneClick, the Client confirms that:

1. the Client has read and understood these Terms;

The Client is responsible for ensuring that all information supplied to OneClick remains accurate and up to date.

4. WhatsApp Business Account

Where the Service involves a WhatsApp Business Account ("WABA"), the Client remains responsible for its business identity, WhatsApp Business account, business information, telephone numbers, administrators, users, message content and activities conducted through its account.

The Client must immediately notify OneClick if it suspects:

OneClick may restrict, suspend or terminate accounts involved in prohibited activities.

10. WhatsApp message templates

Where WhatsApp requires the use of approved message templates, the Client is responsible for submitting accurate and compliant templates.

The Client must not use an approved template for a materially different purpose from the purpose for which it was approved.

OneClick may assist the Client with template submission but does not guarantee approval by WhatsApp or Meta.

Meta or WhatsApp may reject, modify, restrict, disable or reclassify templates in accordance with their policies and systems.

The Client must not attempt to misrepresent the purpose of a message in order to obtain a particular template category, pricing treatment or approval.

11. Message categories

Depending on the applicable WhatsApp Business Platform rules, messages may be categorised as authentication, utility, marketing or service/customer-support communications.

The Client is responsible for ensuring that its intended use is consistent with applicable WhatsApp requirements.

Where WhatsApp or Meta determines or changes the applicable category, pricing or eligibility of a message, OneClick may apply the resulting classification or pricing to the Client's account.

12. Fees and billing

The Client agrees to pay applicable OneClick fees in accordance with the Client's service plan, quotation, order form, invoice or commercial agreement.

Depending on the service, fees may include:

• platform subscription fees;
• messaging charges;
• WhatsApp/Meta-related charges;
• setup or onboarding fees;
• integration fees;
• API usage fees;
• support fees; and
• other agreed service charges.

Third-party fees or charges may change independently of OneClick.

Where Meta or WhatsApp changes applicable pricing, message categories, billing structures or other charges, OneClick may update the Client's applicable charges accordingly, subject to any applicable contractual notice requirements.

Taxes, duties or government charges applicable to the Service may be charged separately where required by law.

13. Third-party services and WhatsApp availability

The OneClick Service depends in part on third-party services, including WhatsApp and Meta infrastructure.

Accordingly, OneClick does not guarantee continuous availability of WhatsApp or third-party services.

WhatsApp or Meta may:

• modify its APIs;
• change technical requirements;
• change messaging policies;
• change message categories;
• change pricing;
• restrict functionality;
• suspend a business account;
• impose messaging limits;
• require additional verification; or
• discontinue or modify features.

Where such changes affect OneClick's Service, OneClick may make corresponding changes to the Platform.

14. Platform availability

OneClick will use commercially reasonable efforts to maintain the availability and reliability of the Platform.

However, availability may be affected by maintenance, upgrades, telecommunications failures, internet failures, cloud infrastructure failures, security incidents, third-party services, regulatory requirements, force majeure events or circumstances beyond OneClick's reasonable control.

Scheduled maintenance may be conducted where reasonably necessary.

15. API and integration use

Where API access is provided, the Client is responsible for:

1. protecting API credentials;
2. implementing appropriate authentication controls;
3. restricting access to authorised systems and personnel;
4. monitoring API activity;
5. preventing unauthorised use;
6. complying with technical documentation; and
7. ensuring that integrated systems do not transmit unlawful or prohibited content.

OneClick may revoke or rotate credentials where necessary for security.

16. Data protection

Each party shall comply with applicable data protection and privacy laws.

Where the Client uses OneClick to process personal data relating to its customers, the Client remains responsible for determining the purposes and lawful basis for that processing.

Depending on the nature of the Service and the relevant processing activity, OneClick may act as a data processor/service provider on behalf of the Client or as a separate data controller for certain operational, security, account and business administration purposes.

The parties may enter into additional data processing terms where required.

The OneClick Privacy Policy explains how OneClick processes personal data in connection with the Platform.

17. Confidentiality

Each party shall keep confidential information received from the other party and shall use such information only for legitimate purposes connected with the Service.

Confidential information does not include information that:

1. is publicly available without breach of an obligation;
2. was lawfully known before disclosure;
3. is independently developed without use of confidential information; or
4. is lawfully received from a third party without confidentiality restrictions.

A party may disclose confidential information where required by law, regulation, court order or competent authority.

18. Intellectual property

OneClick, its software, platform design, documentation, trademarks, logos, interfaces, content and related intellectual property are owned by or licensed to iMartGroup Ltd or its licensors.

Except where expressly permitted, the Client may not:

• copy the Platform;
• reverse engineer the Platform;
• modify or reproduce OneClick software;
• resell access without authorisation;
• remove intellectual property notices; or
• use OneClick trademarks without permission.

The Client retains ownership of its own business content, customer information and materials, subject to the rights necessary for OneClick and its service providers to provide the Service.

The Client grants OneClick the limited rights necessary to process and transmit Client content for the purpose of providing the Service.

19. Security

OneClick will maintain reasonable technical and organisational measures designed to protect the Platform and information processed through it.

The Client is responsible for maintaining appropriate security controls within its own systems, including endpoint security, user access, passwords, API credentials and connected applications.

No internet-based service can guarantee absolute security.

20. Account suspension

OneClick may temporarily suspend or restrict access where reasonably necessary to:

1. protect the Platform;
2. prevent fraud or abuse;
3. investigate suspected security incidents;
4. comply with applicable law;
5. comply with an instruction or restriction imposed by Meta or WhatsApp;
6. address a material breach of these Terms;
7. address non-payment; or
8. protect customers, third parties or OneClick from harm.

Where reasonably practicable, OneClick will provide notice and an opportunity to resolve the issue.

Immediate suspension may occur where delay could create significant security, legal, regulatory or platform risk.

21. Termination

Either party may terminate the Service in accordance with the applicable commercial agreement or subscription terms.

OneClick may terminate or suspend the Service where the Client materially breaches these Terms, engages in prohibited activities, fails to pay applicable fees, or where continued provision would create legal, regulatory, security or third-party platform risk.

Upon termination, the Client's access to the Platform may be disabled.

The parties shall address outstanding payment obligations and applicable data retention or deletion requirements following termination.

22. Data after termination

Following termination, OneClick may retain information where reasonably necessary to:

• comply with legal obligations;
• meet regulatory requirements;
• resolve disputes;
• enforce agreements;
• maintain security records;
• prevent fraud; or
• satisfy legitimate accounting and business requirements.

Personal data that is no longer required will be deleted, anonymised or otherwise handled in accordance with applicable law and the OneClick Privacy Policy.

23. Disclaimers

The Service is provided subject to the applicable service agreement and available functionality.

OneClick does not guarantee that:

1. every WhatsApp message will be delivered;
2. every template will be approved;
3. WhatsApp or Meta services will remain continuously available;
4. a customer's device or network will receive a message;
5. a message will be delivered within a particular period; or
6. third-party systems will remain unchanged.

The Client remains responsible for its business decisions, customer relationships, message content and legal compliance.

24. Limitation of liability

To the maximum extent permitted by applicable law, OneClick shall not be liable for indirect, incidental, consequential or special losses arising from the Client's use of the Service, including loss of profits, business interruption, loss of goodwill or loss of anticipated business opportunities.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited under applicable law.

Any contractual liability cap, where applicable, shall be stated in the Client's commercial agreement or order form.

25. Indemnification

To the extent permitted by law, the Client shall be responsible for claims, losses, penalties, costs and expenses arising from the Client's:

2. violation of these Terms;
3. violation of applicable WhatsApp or Meta policies;
4. unlawful processing of personal data;
5. infringement of third-party rights;
6. fraudulent or misleading communications; or
7. message content or business activities.

This provision does not apply to the extent the relevant loss results from OneClick's own breach of its legal obligations.

26. Changes to the Service

OneClick may update, modify or discontinue features where reasonably necessary for security, technical, legal, regulatory, commercial or third-party platform reasons.

Where a material change adversely affects the Client's contractual rights, OneClick will provide reasonable notice where required.

27. Changes to these Terms

OneClick may update these Terms from time to time.

The updated version will be published on the Platform with an updated effective date.

Where required by law or the applicable agreement, OneClick will provide additional notice of material changes.

Continued use of the Service after the effective date of updated Terms constitutes acceptance of the updated Terms to the extent permitted by law.

28. Governing law

These Terms shall be governed by and interpreted in accordance with the laws of the United Republic of Tanzania, unless a separate written agreement between OneClick and the Client provides otherwise.

Nothing in these Terms prevents either party from exercising rights available under mandatory applicable law.

29. Dispute resolution

The parties shall first attempt to resolve any dispute through good-faith discussions between their authorised representatives.

Where the dispute cannot be resolved through negotiation, it may be referred to the competent courts or other lawful dispute-resolution mechanism applicable in Tanzania, subject to any separate written agreement between the parties.

30. Force majeure

OneClick shall not be responsible for failure or delay caused by events beyond its reasonable control, including natural disasters, telecommunications failures, internet disruption, power failures, government actions, regulatory restrictions, cyber incidents by third parties, war, civil unrest, labour disputes, infrastructure failures or interruption of third-party services.

31. Severability

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions shall continue to apply to the extent permitted by law.

32. Entire agreement

These Terms, together with applicable service orders, commercial agreements, pricing schedules, the OneClick Privacy Policy and other expressly incorporated documents, constitute the agreement governing the Client's use of the Service.

Where there is a conflict between these Terms and a separately signed commercial agreement, the separately signed agreement shall prevail to the extent of the conflict.
