Nexus Terms of Service

Updated 13 November 2026

This agreement is between you and PT IZAAJA SOLUSI DIGITAL, Jl. Marelan Raya 7 Pasar 1 Tengah, Medan Marelan, Sumatera Utara 20255, Indonesia, tax ID 10.000.000-083.002.96 (“we”). These terms apply when you use Nexus at nexus.izaaja.com or in the Nexus Android app; by creating an account you accept them. The parts about WhatsApp, money and customer data are written to be the clearest.

1. What Nexus does

Nexus helps a business receive and answer customer messages from WhatsApp (and Instagram and Facebook, if you connect them) in one inbox, keep customer contacts, run a sales pipeline, send broadcasts to contacts who agreed to receive them, and use an AI chatbot that answers only from the shop data you allow.

Nexus is a work tool that connects your WhatsApp number to Meta. Nexus is not WhatsApp, not part of Meta, not a bank, and not a legal or tax adviser.

2. Who may use it

You must be at least 18, or the age of majority in your country if higher, and be authorised to act for the business you register. You must also be eligible to use the WhatsApp Business Platform under Meta’s terms in your country.

3. Accounts, agents and roles

You are responsible for everything that happens in your account, including messages sent by agents you invite. Keep your password safe; tell us at once at nexus@izaaja.com if your account is used without permission.

One agent account is for one person. Paid plans are counted per customer-service agent seat, and you set each agent’s role and permissions.

4. Your WhatsApp number and Meta account

You connect your number in Meta’s own sign-up window (Embedded Signup), with your own consent. The WhatsApp Business account and the number stay yours, not ours. You must be entitled to the number and must accept Meta’s terms for the WhatsApp Business Platform, including Meta’s business and commerce policies.

You can disconnect the number from Nexus at any time. Disconnecting does not delete your WhatsApp Business account at Meta.

5. WhatsApp message fees are paid to Meta

Meta charges a fee per WhatsApp message, by category and country. You pay that fee directly to Meta, through the payment method you attach to your own WhatsApp Business account, at Meta’s official rates. We do not resell it, advance it, or add any margin to it. You only pay us for your Nexus plan.

Fee amounts shown in Nexus are estimates from Meta’s rates, not an invoice from us, and can differ from Meta’s bill. Without an active payment method at Meta, template messages cannot be sent; that is a Meta rule, and Nexus shows it as a warning.

6. Rules for sending messages

You use Nexus to message your own customers and must follow the WhatsApp Business policies and Meta’s business and commerce policies as they apply.

Consent (opt-in): send promotions and broadcasts only to people who agreed to receive them, and keep the proof. Stop at once when someone asks.
24-hour window: a free-form reply may be sent only within 24 hours of the customer’s last message. After that only a message template approved by Meta may be sent.
Sending limit: Meta limits how many different customers you can reach with templates per 24 hours, and the limit goes up or down with your number’s quality. Nexus shows the limit and holds the rest of the queue, but the limit is set by Meta.
No spam, misleading messages, unlawful content, or selling goods or services that Meta’s policies or your country’s law forbid.

Breaking these rules can make Meta lower your number’s quality, limit your sending, or close your WhatsApp Business account. That is Meta’s decision; we cannot reverse it and are not liable for its consequences.

7. Meta’s actions and Meta’s services

Nexus depends on Meta’s services. Meta may change rules, rates or limits; reject your templates or display name; restrict or close your number; or have outages. When that happens Nexus shows the status and the next step as far as Meta lets us know, but appeals and the final decision are with Meta.

8. Your customers’ contact data

For data about the people you message through Nexus (phone number, name, chat content, labels, notes and consent status), you are the data controller and we are the processor, working on your instructions. You must have a lawful basis and any needed consent before you store and contact them, and you must answer their requests to see or delete their data. Details are in the Privacy Policy and the Data Processing Agreement.

9. The AI chatbot

The Nexus AI chatbot drafts answers with an AI model (currently DeepSeek) only from the shop data you allow, and hands the chat to a person when it is unsure, or when the customer asks for a person or complains. In suggestion mode an answer is only a draft that your agent sends; in automatic mode an answer is sent by itself only within the 24-hour window.

AI can be wrong. Check its answers before relying on them, and set its mode and quota to fit your business. You remain responsible for what is sent to your customers. If the AI service is down, the chatbot stays silent and chats still reach your agents.

10. Free and paid plans

The free plan includes 1 WhatsApp number, 1 agent (the owner) and 500 contacts, with the WhatsApp inbox, quick replies and contacts; it has no broadcasts, pipeline, AI chatbot, social inbox or reports. Paid plans are priced by number of agent seats, with allowances for numbers, contacts, broadcasts and AI replies per tier. Current plans and prices are shown on the Nexus home page and in the app before you pay.

If your contacts go over the plan allowance, chats from new numbers still arrive and can be answered, but are not saved to the contact list until you upgrade or delete contacts.

Paid plans are paid in advance through Midtrans or Google Play. We tell you of a price or plan change at least 30 days ahead; it applies from the next period. Nexus plans and add-ons are sold only by PT IZAAJA SOLUSI DIGITAL through the routes on the Official channels page; a purchase through anyone else is not a transaction with us and we do not support it.

11. Payment, term and refunds

When a paid plan ends, the account returns to the free plan; pages that exist only on paid plans are locked, and your data is not deleted. Refunds follow the Refund Policy. Your rights as a consumer under the law of your country are not reduced by this section.

12. What is not allowed

Messaging people who did not agree to receive messages, or ignoring a request to stop.
Using Nexus for spam, fraud or phishing, or to ask for sensitive data such as card numbers or passwords over WhatsApp.
Selling goods or services forbidden by your country’s law or Meta’s policies.
Taking apart, copying or getting around the app, plan limits or our security, or using WhatsApp through unofficial means that break Meta’s terms.
Sharing one agent account among many people to avoid paid seats.
Claiming to be our agent, reseller, distributor, partner or employee, or selling, renting or giving access to Nexus, accounts or plans without our written permission.
Using the names Izaaja, Nexus, Lamxo, Sello or Qu3u3, our logos, or confusingly similar names or domains, to sell anything or to look like us.
Giving false identity or business details when signing up or paying, or using a payment method you are not entitled to use.

Serious violations can lead us to stop the account. Where possible we tell you and give you the chance to fix things first.

13. Outages and limits of liability

We work to keep Nexus running but do not promise it is free of interruption. WhatsApp messages pass through Meta and other networks; delays, undelivered messages, or outages on the side of Meta, carriers or the internet are outside our control.

To the extent the law allows, our liability for any loss is capped at the Nexus subscription fees you paid in the last 3 months. We are not liable for lost profit, indirect loss, restriction or closure of your account by Meta, message fees charged by Meta, AI answers you sent without checking, your agents’ actions, or failures of networks, Meta and other providers. This cap does not apply to our wilful misconduct or gross negligence, and does not reduce rights that by law cannot be limited.

We are not liable for loss caused by third parties pretending to be us, for example fake shops, payment links, social media accounts, apps or emails that did not come from the routes on the Official channels page or from an @izaaja.com, @qu3u3.com or @lamxo.com address, unless the loss was caused or contributed to by our own fault. If this happens to you, tell us at nexus@izaaja.com and we will help report it.

14. Indemnity

You indemnify us against claims by others arising from messages you send, contacts you store or message without the right to, goods you sell, or your breach of this agreement, Meta’s policies and applicable law.

15. Events beyond control

Neither side is in breach if prevented by natural disaster, war, riot, widespread power or internet failure, government action, outages or policy changes at Meta, or other events beyond reasonable control.

16. Ending the agreement

You can stop at any time, disconnect your WhatsApp number, and ask for your data to be deleted through the Delete data page. We can end the agreement with 30 days’ notice, or at once for a serious violation, a legal duty, or a request from Meta. Before an account is closed you have time to export your contacts. We keep billing records for as long as the law requires.

17. Governing law

This agreement is governed by the law of the Republic of Indonesia. If you are a consumer, the mandatory consumer protections of the country where you live still apply. We prefer to settle things by talking; if that fails, disputes go to the competent courts in Indonesia, unless your country’s law says otherwise.

18. Changes

We announce important changes by email or in the app at least 30 days before they apply, and the latest date is shown at the top of this page. If you do not agree, you can stop before that date at no extra cost.

19. Intellectual property

The app, site, names, logos and design of Nexus belong to PT IZAAJA SOLUSI DIGITAL. A subscription gives you the right to use Nexus for your own business while the agreement runs; ownership does not pass. Your contacts, chats, products and business data remain yours, and we use them only to run Nexus for you, as set out in the Privacy Policy. WhatsApp, Facebook, Instagram and Messenger are trademarks of Meta Platforms, Inc.

20. General

This agreement, with the Privacy Policy, Refund Policy and Data Processing Agreement, is the whole agreement about Nexus. If one clause is unenforceable, the others still apply. You may not transfer this agreement without our consent; we may transfer it together with the Nexus business, with notice. If the Indonesian version and another language differ, the Indonesian version applies.

Consent and electronic records. You accept these terms electronically when you create an account or pay, and that consent binds you as a signed document would. Records kept by our systems, such as sign-in, payment and account change logs, may be used as evidence as Indonesian law provides (Law No. 11 of 2008 on Electronic Information and Transactions as amended, articles 5 and 18). You may still present your own evidence.

How we contact you. We contact you only from @izaaja.com, @qu3u3.com or @lamxo.com addresses, inside the app, and through the routes on the Official channels page. We never ask for your password or one-time code (OTP).

21. Reporting infringement and impersonation

If you believe content on Nexus infringes your rights, if you receive unwanted messages from a Nexus user, or you find a shop, account, app, domain or message pretending to be Izaaja or Nexus, report it to nexus@izaaja.com. Include who you are and how to reach you, which right is infringed or what is pretending to be us, the link or location, and a statement that your report is true and made in good faith.

We review every report and may suspend the account concerned. If we act on your account or content, we tell you why, and you may object by sending an explanation and proof; we review it and restore things if the report was wrong. A deliberately false report can lead to the reporter’s account being closed. We close the accounts of users who repeatedly offend, and cooperate with law enforcement and with authorities’ requests that we must answer by law.
