Terms of sale

Version 1.4.0, in force since October 20, 2026. This English text is the binding version of this document; the versions in other languages are translations provided for convenience.

1. Who we are

The NordixAIgency service is provided by:

• Company: AD Caldas Innotec SA
• NIF: A66316399
• Registered office: Calle Blanco 1011595 Torrecera (Cádiz)Spain
• Email: legal@nordixaigency.com
• Direct contact: the contact form of nordixaigency.com.

In these terms, «we» and «NordixAIgency» mean that company. NordixAIgency is a brand operated by AD Caldas Innotec SA. The solutions are built on NordixBIOS, the AI-agent platform of Nordix Systems; AD Caldas Innotec SA is the party answerable to the Customer for the service.

2. Purpose and who these terms are for

2.1. These terms govern the purchase of NordixAIgency plans: artificial-intelligence assistants that serve a business's customers on the plan's channels (for example calls, WhatsApp, Instagram, Messenger, email, website chat or SMS) and work with the tools the business connects (for example its calendar or its online shop).

2.2. The service is aimed only at businesses and professionals buying for their trade, business or profession (the «Customer»). It is not aimed at consumers. By signing up and accepting these terms, the Customer declares that it acts for that purpose.

2.3. The contract is concluded when the Customer completes the sign-up in the NordixAIgency app (app.nordixaigency.com), accepts these terms and the data processing agreement, and pays the first fee. The prices and descriptions on the website are information about the service, not a binding offer.

3. The service

3.1. The Customer builds its plan from the price list in force when it signs up (nordixaigency.com/es/en/pricing/): the lines Messages, Calls and Confirmations, each in several sizes, and the add-ons (clause 3.5). Each size of a line includes, every month, an amount of usage (messages; minutes of calls, with the phone numbers of that size; or appointments) on that line's channels. A plan has at least one line or one add-on, and the price list says which lines are bought only together with another. The Confirmations line works only with Bookings switched on in the app, and with an appointment calendar: the one included with every plan, or an external calendar linked with a Connector (clause 3.5). Calls and phone numbers come only with the Calls line.

3.2. The service is self-service: the Customer sets up its assistant in the app (opening hours, services, answers, when to pass the conversation to a person) and connects its own accounts and tools. The assistant introduces itself as an automated assistant in its first reply.

3.3. Some channels and tools are third-party services (for example WhatsApp and other Meta services, Google Calendar or the Customer's own Stripe account for payment links). The Customer uses them under those third parties' terms, which may change or limit how they work.

3.4. Any payment the assistant handles for the Customer (deposits, payments, refunds to its customers) always goes through the Customer's own account and, where so configured, with its approval. We never receive that money.

3.5. Add-ons. The Connectors add-on links the Customer's assistant to the external systems on our list that the Customer connects (for example Google Calendar or Outlook), with no limit on the number of systems and with every calendar and account of each system; we activate the systems on the list on demand. Each system linked is one Connector, and the add-on is bought once, at a fixed monthly price, with no quantity. The appointment calendar included with every plan needs no Connectors. A system that is not on the list and needs development is linked with a custom integration (clause 4.4). The Customer switches each linked system on or off in the app. When the Customer has switched on its management number in the app (the app's phone number that it calls from its verified mobile, with its PIN, to manage its business by voice) and has the Connectors add-on without a custom integration, that number works with the linked systems at the basic level: it does not handle reports, invoices, sales, payments, accounting, exports, bulk changes or bulk reads of money, sales or customers of the linked systems. Questions about the Customer's own plan and its usage of the service stay available on that number at every level.

3.6. Passing a call to a person. Passing a call to a person on the Customer's team is optional: the Customer switches it on in the app's panel, and each minute the call is with its team is charged at the price per minute of the price list.

4. Prices and taxes

4.1. The prices are those of the price list for Spain in force when the Customer signs up. The plans and the add-ons have monthly prices, with no setup fee; only a custom integration has a set-up (clause 4.4). All prices exclude VAT and any other indirect tax that applies, which the invoice adds as the law requires.

4.2. Usage beyond what a line includes is charged at the unit price that the same list sets for the size of that line: per extra message on the Messages line, per extra minute of calls on the Calls line and per extra appointment on the Confirmations line. If the plan does not include the Messages line, each message is paid per use, with nothing included, at the highest price of an extra message among the sizes of that line in the same list.

4.3. If we publish a new version of the price list, it applies only to new sign-ups: the Customer's subscription keeps the version it was bought under, including for its plan changes.

4.4. Custom integration. A custom integration is a custom job by our technical team, of one of two kinds: a new integration, for a system that needs development (for example an ERP or a CRM), or a special configuration of the Customer's assistant (for example reports, routines or a tailored agent). A new integration is ours (clause 14) and is private by default: only that Customer's assistant uses it; if we add it to our list, it also becomes available to the other Customers. The use of the integration is included in the job's monthly fee, with no need for the Connectors add-on. While a custom job is live, the Customer's management number (clause 3.5) also gives full use, by voice, of the systems linked through the Customer's new integrations, which are served there only to that Customer, and, if the Customer also has the Connectors add-on, of the systems linked with Connectors, including the operations that the basic level of clause 3.5 leaves out. Without the Connectors add-on, the management number reaches none of the systems on our list. The set-up of each job starts from the amount the price list shows («from», VAT not included) and is paid at purchase; its final amount depends on the work the job needs and is set in a final quote that we send to the Customer.

4.5. Refund of the set-up. Until the Customer accepts the final quote, we refund the whole set-up if it asks us to. If the final quote is higher than what was paid, the Customer pays only the difference when it accepts it. Once the quote is accepted and the work has started, the set-up is no longer refunded.

4.6. The monthly fee of each custom job, at the price of the price list, is charged from the day that job goes live, not before.

4.7. Requests and questions about a custom integration go to support@nordixaigency.com.

5. Payment, invoicing and renewal

5.1. You pay when you sign up. The first monthly fee is charged at sign-up, before the service is activated, together with the set-up of a custom integration when the Customer buys one (clause 4.4), through the Stripe payment gateway; there is no trial period without payment. The plan's phone numbers are obtained only after that first payment.

5.2. The subscription is monthly and renews automatically every month on the anniversary of the sign-up. Each monthly period starts on that date. What the plan includes restarts at the start of each period; what is not used in a period does not carry over to the next one.

5.3. Usage beyond what is included in a period is invoiced when that period closes, on the renewal invoice of the following period.

5.4. Before paying, the Customer gives its country, address, company name and, where applicable, its VAT number. Invoices are issued electronically and are available in the billing section of the app, where the Customer can also change its payment method.

5.5. Plan changes. The Customer changes its plan line by line and add-on by add-on: it adds or removes a line, changes the size of a line, and adds or removes an add-on. An increase (a line or an add-on added, a larger size) applies at once; the prorated difference for the rest of the period is charged on the next invoice or, if the account closes first, on the closing invoice. A decrease (a line or an add-on removed, a smaller size) applies at the end of the period already paid and can be undone until then; on that date the channels the new plan does not include close and the numbers above the new plan's are released. We tell you by email 7 days before what closes. A single request that mixes an increase and a decrease is refused: the Customer makes them one after the other.

5.6. Non-payment. If a renewal payment fails, the assistant keeps working for 48 hours while the payment is retried; after that, the service is suspended until the invoice is paid. Non-payment does not close the account automatically, but it allows us to terminate the contract (clause 8.5).

6. Monthly spending cap

6.1. The Customer may set in the app a monthly spending cap for usage beyond what its plan includes. It is optional, except for the solutions where the price list requires it, which ask for it at sign-up. With no cap, all usage beyond what is included is invoiced.

6.2. We warn you when 80% of the cap is reached. When 100% is reached, the assistant stops answering on the channels until the next period starts, and no usage beyond the cap is invoiced for that period. If the Customer raises the cap above what has already been spent, the assistant works again at once.

7. 14-day money-back guarantee

7.1. If, within 14 calendar days from the date of the first payment, the service is not right for the Customer, it may ask us for a refund and we give back everything it has paid for its plan: the plan and add-on fees, the VAT, the usage beyond what is included and the phone numbers. The guarantee does not cover the set-up of a custom integration, which follows clause 4.5.

7.2. How to ask. By email to support@nordixaigency.com or to legal@nordixaigency.com, or through the contact form of nordixaigency.com, within those 14 days, from the account's email address or giving the business's name and that address, so that we can identify the account.

7.3. What we do. We refund the amount in Stripe, to the same payment method it was paid with. How long the amount takes to reach the Customer's account depends on its bank or card issuer. If usage is still to be invoiced when the account closes, it is not charged either.

7.4. The account closes at that moment. When we process the refund we close the account at once, without waiting for the end of the paid period: the assistant stops, the channels close and the phone number is released and cannot be recovered. If the Customer forwarded the calls of its own line to the plan's number, it must undo the forwarding with its carrier. The Customer's WhatsApp number remains its own.

7.5. Once per business. The guarantee applies only once per business: a business identified by the same tax id (NIF) can use it only once, even if it signs up again.

8. Term, no minimum term and closing the account

8.1. The contract has no minimum term: it lasts as long as the subscription renews each month.

8.2. The Customer may close its account at any time from the app's settings; the closure is confirmed with a code we send to the account's email address.

8.3. The closure takes effect at the end of the period already paid: the assistant keeps working until that date, and the Customer can undo the closure until then. The usage beyond what is included in the last period is invoiced at the closure. Outside the guarantee of clause 7, the amount of the period already paid is not refunded.

8.4. When the account closes, the channels close and the plan's phone number is released and cannot be recovered. If the Customer forwarded the calls of its own line to that number, we send a notice 7 days before so that it undoes the forwarding with its carrier.

8.5. We may terminate the contract, after notice by email, if the Customer does not pay an overdue invoice, uses the service unlawfully or against these terms or those of the third parties of clause 3.3, or gives false data at sign-up. In case of unlawful use or risk to third parties we may suspend the service at once.

9. Phone numbers

9.1. The phone numbers included in the plan are assigned to the Customer's account while the subscription is active; they do not become the Customer's property. In Spain they are assigned in the numbering area of our registered office and registered with our details.

9.2. A number is released when the account closes, when a downgrade that does not include it applies and when the guarantee of clause 7 is processed. A released number goes back to the carrier and may be assigned to someone else.

10. The Customer's obligations

The Customer undertakes to:

• give truthful sign-up data and keep it up to date;
• keep safe the access to its account and to the third-party accounts it connects;
• set up its assistant's information and instructions with due care, and answer for their content;
• inform its own customers about the processing of their data and comply with the rules that apply to it, including data protection and commercial communications;
• not use the service to send unsolicited communications or for unlawful or misleading purposes, or purposes that infringe third parties' rights, and respect the policies of the third-party channels.

11. Data protection

11.1. We process the data of the Customer and of the people who represent it as controller, under the app's privacy notice and the privacy policy of this website. Privacy contact: privacy@nordixaigency.com.

11.2. We process the data of the Customer's own customers that the assistant handles while providing the service on the Customer's behalf, as processor, under the data processing agreement (GDPR art. 28), which is part of the service and which the Customer accepts at sign-up.

12. Artificial intelligence and limits of the service

12.1. The assistant's answers are generated automatically from the Customer's set-up and may contain errors. The Customer decides which matters always go to a person.

12.2. The assistant does not replace the emergency services, or a professional where a matter requires one.

12.3. We take reasonable care over the availability of the service, but we do not guarantee that it works without interruption; the service also depends on third parties (carriers, channels and connected tools).

13. Liability

We are liable for damage caused by a breach of these terms. Save for wilful misconduct or gross negligence, our total liability is limited to the amounts the Customer paid in the 12 months before the event that gives rise to it, and we are not liable for loss of profit or indirect damage.

14. Intellectual property

The app, the software and the marks are ours or our licensors'. The Customer keeps its content and authorises us to use it only to provide the service.

15. Changes to these terms

We may change these terms by telling the Customer by email at least 30 days in advance. The changes apply from the period after that notice; if the Customer does not agree, it may close its account before then. Price changes follow clause 4.3.

16. Notices

Notices to the Customer are sent to its account's email address. The Customer's notices go to legal@nordixaigency.com or through the contact form of nordixaigency.com.

17. Language, governing law and jurisdiction

17.1. These terms are governed by Spanish law.

17.2. For any dispute, the parties submit to the courts of the registered office of AD Caldas Innotec SA.

17.3. These terms are written in English, and the English version is the binding one. The versions in other languages are translations provided for convenience; in case of discrepancy the English version prevails.
