Terms of service

What this covers

These terms govern the use of Mabinn, a product of JOINLEAN, with address at Mérida, Yucatán, México, by the business that contracts it and by the people that business authorizes. Using the service means accepting them.

They are addressed to that business. If you are a person who wrote to a business through WhatsApp, Instagram or Messenger, what applies to you is the privacy notice, not this document.

What Mabinn does

Mabinn brings the conversations of a business into one place, links them to its customers and sales, and lets it organise the follow-up: pipeline, quotes, appointments, campaigns and reports. What each plan includes is stated when it is contracted.

Mabinn is a tool. The commercial decisions, the content sent to customers and the fulfilment of what is promised to them belong to the business that uses it.

Accounts and access

The business names who may access and with what permissions, and is responsible for what those people do with their credentials. Credentials are personal and must not be shared.

Tell us immediately at info@mabinn.com if you suspect someone is using an account without authorization.

Your data stays yours

The customers, conversations, quotes and sales a business loads into Mabinn belong to that business. We do not use them to train models, we do not sell them, and we do not share them with other clients.

We use them only to run the service, and in aggregate form — never identifiable — to understand how the product is used and improve it.

How we handle personal data on your behalf

For the personal data of your own customers, you are the controller and we are the processor. That is not a formality: it decides who answers to whom, and it commits us to the following for as long as the relationship lasts.

• We process that data only to provide the service and following your instructions — never for our own purposes.
• We keep it confidential, and we require the same from any provider that touches it on our behalf.
• We maintain security measures appropriate to the data, and we tell you without delay of any breach that affects it.
• We do not transfer it to third parties, except to the providers needed to run the service and to authorities when a law requires it.
• We help you answer the access, rectification, cancellation and objection requests your customers send you.
• When the relationship ends we delete it, on the terms of the deletion section below.

What we need from you in return

You send the messages; we only carry them. So the obligations that travel with them are yours:

• Publish your own privacy notice and make it available to the people whose data you load into Mabinn.
• Have their consent before writing to them, and keep proof of it.
• Honour every request to stop, including the ones that arrive as a reply to a message.
• Give us lawful instructions. If one of them would breach data protection law, we will tell you and we will not carry it out.

Third-party platforms

Mabinn connects to WhatsApp, Instagram and Messenger, operated by Meta. Using those channels also means accepting Meta's terms, and the business is responsible for having its own account in good standing.

Some things depend on Meta and not on us: approving a message template, the limit of how many messages can be sent, the twenty-four hour window to reply freely, and the quality rating of a number. We report faithfully what those platforms answer, and we cannot override their rules.

Acceptable use

Using Mabinn to do any of the following is not allowed:

• Send messages to people who did not give consent, or keep sending them after they asked to stop.
• Send content that is illegal, misleading, or that impersonates another person or business.
• Buy or use contact lists that were not obtained legitimately.
• Attempt to break the security of the service, or access data belonging to another client.
• Resell the service, or give access to it to someone outside your own operation.

Claims that come from your own use

If a third party — a customer, a competitor, an authority — makes a claim against us because of the messages you sent, the data you loaded, the content you published or a breach of your obligations under these terms, you take it on: you defend us, you cover the resulting costs, and you hold us harmless.

We will tell you as soon as we learn of such a claim, and we will not settle it on your behalf without telling you first.

Price, tax and invoicing

The plan is paid in advance for each period, at the price in force when it is contracted. Prices are stated without VAT, which is added where it applies, and we issue the corresponding invoice.

A price change is announced at least thirty days before the period it applies to, so there is always time to cancel before it takes effect.

If a payment fails we notify it and allow a grace period; if it stays unpaid, access may be suspended while the data is preserved.

What Meta charges for message traffic is billed separately by Meta to the business that owns the number. That cost is not part of the Mabinn plan.

Term and renewal

The plan runs for the contracted period and renews automatically for equal periods unless it is cancelled before the current one ends. Cancelling is done from the platform or by writing to us, and takes effect at the end of the period already paid.

There are no refunds for a period already started, except where the law requires one.

Availability

We work to keep the service available and to announce planned maintenance in advance. We cannot guarantee uninterrupted operation: part of it depends on providers outside our control, including the messaging platforms themselves.

Neither party answers for a failure caused by something genuinely beyond its control — an outage of a third-party platform, a natural disaster, an act of authority. The obligation is suspended while the cause lasts, not cancelled.

The service is provided as it stands, with no committed uptime percentage and no implied warranty beyond what the law does not allow us to exclude. Features released as previews or betas are offered to be tried, not relied on.

Keeping your own copy is up to you: export your data periodically. Our backups exist to restore the service, not to answer individual recovery requests.

Ending the service, and what happens to the data

We may suspend an account that breaches these terms, telling it why and giving it a chance to fix it when the breach allows for that.

Some cases do not allow for that wait, and there we suspend first and explain immediately afterwards: an active security risk, an order from an authority, or a messaging platform requiring it of us.

Once the relationship ends, you can export your data for thirty days. After that we delete it within ninety days, keeping only the invoices tax law obliges us to keep and a security log of the deletion.

Liability

Mabinn is provided as it is described. We are not liable for lost profit, or for damage arising from the use a business makes of the service or from failures of third-party platforms. Where liability applies, it is limited to the amount paid for the service in the three months before the event.

That limit does not apply to fraud or wilful misconduct, and nothing here limits rights that Mexican law grants and does not allow to be waived.

Any claim arising from these terms must be brought within one year of the event that gave rise to it.

Intellectual property

The software, the brand and the documentation belong to us. Contracting the service grants the right to use it, not to copy, resell or derive it.

If you send us a suggestion and we build it, the resulting feature is ours — and using it costs you nothing.

Assignment and notices

Neither party may assign this agreement without the other's consent, except in a merger or a sale of the whole business, where it travels with it.

Notices between us are valid by email: ours to the address registered on the account, yours to info@mabinn.com.

Changes and applicable law

If we change these terms we will announce it inside the product at least thirty days before they take effect. Continuing to use the service after that means accepting the new version; if you do not accept it, you may cancel without penalty.

Not enforcing a clause on one occasion does not waive it. If a court finds one clause invalid, the rest stays in force.

These terms are governed by the laws of the United Mexican States, and any dispute belongs to the courts of Mérida, Yucatán, with both parties waiving any other jurisdiction that might correspond to them.
