Terms of service

Last updated: September 12, 2026.

These terms govern the purchase and use of the services of Chultún, a brand of CONSULTORA Y COMERCIALIZADORA VIAL, S.A.S. de C.V. ("Chultún", "we"), with its registered address at Calle 4 368-A Interior x 7 y 9, Mérida, Yucatán, ZIP 97130, Mexico. By hiring a service, registering your business or connecting your accounts, you accept these terms. If you sign up on behalf of a company, you represent that you have the authority to bind it.

• Modules for Odoo. Automations we install in your Odoo Online through its external API, without installing third-party modules. They're licensed on an annual subscription, module by module.
• Messaging assistant. Automated service for the customers who message your business on Messenger, Instagram and WhatsApp, with the contact and the opportunity recorded in your Odoo.
• Project services. Odoo implementation and migration, website optimization, Google ranking and SEO, and social media audits. They're hired through a written quote, with their own scope, timeline and conditions; these terms apply to whatever the quote doesn't cover.

If we sign a separate contract or service order with you, that document prevails over these terms wherever they differ.

To provide the service we need you to give us an API key for your Odoo with the necessary permissions —never your password— and, for messaging, to connect your Meta Pages and accounts to our application. You're responsible for the information you register, for keeping it up to date and for the activity carried out with your credentials. If you suspect unauthorized use, let us know immediately at hola@chultun.com.

We undertake to: use your key only to provide the contracted service; keep it encrypted while the service is active; keep a record of what we install or modify in your Odoo; and revoke or delete the access when the service ends, unless you hire maintenance.

• To use the service in accordance with the law and the policies of the platforms you connect (Odoo, Meta and WhatsApp), including the rules on business messaging and on your contacts' consent.
• To have the consent or legal basis needed for us to process your customers' data on your behalf, and to inform them in accordance with our Privacy notice.
• To keep an Odoo plan that allows access to the external API, and to keep your own backups.
• To pay the agreed price within the agreed terms.

You may not use the service to send unsolicited or misleading messages, for unlawful activities, to infringe third-party rights, or to attempt to access other customers' systems or data. You may not copy, redistribute, resell or publish our code or our materials either. We may suspend the service in the event of a prohibited use, notifying you and explaining the reason.

Modules are billed on an annual subscription, per module, according to the number of users in your Odoo in tiers: the price goes up by tier, not per individual user. The messaging assistant and project services are billed according to the quote you accept. Prices are stated in Mexican pesos plus VAT. WhatsApp messages are billed separately by Meta, at its current rates. We issue a tax invoice for every payment.

Our services run on Odoo Online and on Meta's platforms, which belong to third parties and may change their terms, their prices or the way they work. If a change to those platforms prevents us from providing a contracted service, billing for that service stops for as long as the impediment lasts and resumes when it becomes available again; time paid for and not used is credited. We undertake to notify you of the impediment and its resolution, and to fix whatever depends on us when an Odoo update affects what we installed.

The code, the materials and the Chultún brand are ours. When you sign up you receive a non-exclusive, non-transferable license to use them for your business for the duration of the service. The fact that the code is readable inside your Odoo doesn't change that license. What you record in your Odoo —contacts, messages, opportunities, catalog— is yours.

We process your customers' data on your behalf, to provide the service, in accordance with the Privacy notice. The assistant states that it's automated in its first message and lets people ask for a person; its replies are based on your business's catalog and information, and your team can step into any conversation from your Odoo.

We provide the service with due diligence and appropriate technical means, and we fix at no cost any defects that depend on us. We do not guarantee specific business results or the continuity of third-party platforms. Our liability towards you is limited to direct damages and to the amount paid for the affected service in the preceding twelve months, without prejudice to the rights the law grants you as a consumer, which cannot be waived.

Subscriptions run for one year and renew for equal periods unless either party gives notice otherwise before the expiry date; we'll notify you in advance of each renewal. You can cancel at any time by writing to hola@chultun.com; the cancellation takes effect at the end of the paid period. We may terminate the service for breach of these terms, notifying you and giving you the opportunity to fix it. Upon termination, we revoke our access and delete your registration in accordance with Data deletion; whatever lives in your Odoo stays with you.

Each party will treat as confidential the non-public information it receives from the other in connection with the service —your credentials, your catalog, your customers and your processes; our code and our methods— and will use it only to fulfill these terms. The obligation survives for three years after the service ends and does not apply to public information, to information the receiving party already legitimately knew, or to information that must be disclosed by law, in which case the other party will be notified where possible.

If your use of the service in breach of these terms or of the law —in particular messages sent without your contacts' consent, or content that infringes third-party rights— gives rise to a claim against us, you will be liable for the reasonable damages and costs it causes us. Likewise, we will be liable to you for third-party claims arising from our code or our materials infringing intellectual property rights.

We are an independent provider. These terms do not create a partnership, agency, franchise or employment relationship between the parties, and neither party may bind the other towards third parties.

These terms are governed by the laws of the United Mexican States. For any dispute, the parties submit to the competent courts of Mérida, Yucatán, without prejudice to the rights the Federal Consumer Protection Law grants to consumers, including the jurisdiction of the Federal Consumer Protection Agency (PROFECO).

These terms, together with the Privacy Notice and the quote or contract you accept, are the entire agreement between the parties regarding the service. If any clause is found invalid, the others remain in force. A party's failure to enforce a clause does not mean it waives it. You may not assign your rights under these terms without our consent; we may assign them to whoever continues our business, notifying you. These terms do not grant rights to third parties.

Communications about the service are made by email: we write to the address you registered; you write to hola@chultun.com. You agree to receive notices, invoices and changes to these terms by that means. We may send you information about Chultún news; you can ask us to stop at any time.

We may update these terms. We will publish the current version on this page with its date and, if the change affects a contracted service, we will notify you by email in advance. If you don't accept the change, you can cancel before it takes effect.
