ConSergio.ai — DevInterface srl Version 1.1· Last updated: 20 August 2026
Language. This English text is a courtesy translation of the Italian original. In the event of any discrepancy or conflict between the two versions, the Italian version shall prevail.
These Terms and Conditions (the “Terms”) govern the use of ConSergio.ai (the “Service”), a SaaS software platform that enables accommodation businesses to offer their guests a digital concierge accessible via QR code, including a service catalogue, request management and an AI-powered conversational assistant.
The Service is provided by DevInterface srl, with registered office at Via Guglielmo Marconi 20, 37012 Bussolengo (VR), Italy, VAT no. 04080300231 (“DevInterface”, the “Provider” or “we”).
By registering for the Service and ticking the relevant acceptance box, the Customer declares that it has read, understood and fully accepted these Terms, the Privacy Policy and the Data Processing Agreement (DPA), which forms an integral part hereof.
1. Definitions
- Customer (or Property Operator): the natural or legal person owning or operating an accommodation business who subscribes to the Service.
- Guest: a person staying at the Property who accesses the web app via QR code.
- Staff Users: the natural persons authorised by the Customer to access the management panel, with the role of Owner or Reception.
- Account: the commercial entity registered to the Customer, to which the subscription and one or more Properties are linked.
- Property: the individual accommodation unit configured within the Service, constituting the data isolation boundary.
- Customer Content: texts, service descriptions, images, documents, PDFs, FAQs, local information and any other data the Customer uploads or configures within the Service, including content used to feed the AI Assistant.
- AI Assistant: the conversational component of the Service that responds to Guests based on Customer Content and, where applicable, on configured external sources.
- External sources: third-party information sources (e.g. weather, events, points of interest, web search) that the Customer may enable, within the limits of its Plan, to enrich the AI Assistant’s responses.
- Plan: the subscription tier taken out (Base, Pro or Max), with its associated functional and commercial limits.
2. Subject matter of the Service
2.1 DevInterface grants the Customer a non-exclusive, non-transferable and non-sublicensable right to use ConSergio.ai in accordance with the Plan subscribed and for the duration of the subscription.
2.2 Within the limits of the Plan, the Service includes: the Guest-facing web app, accessible without installation or registration via a QR code linked to the room; the Property’s service catalogue and information content; the collection and management of Guest requests; the multilingual AI Assistant; the management panel for Staff Users; statistics and configuration functions.
2.3 The Service is provided on a SaaS basis, accessible via browser. DevInterface does not supply hardware, connectivity, QR code printing or on-site installation services, unless otherwise agreed in writing.
2.4 The Service is subject to continuous development. Features announced as planned for future releases are not contractually binding and do not affect the fees payable for the features available at the time of subscription.
3. Registration, Account and Staff Users
3.1 Registration is reserved to persons acting in the course of their professional or business activity. The Service is not intended for consumers.
3.2 The Customer undertakes to provide truthful, complete and up-to-date registration details and is responsible for the confidentiality of its own credentials and those of its Staff Users, as well as for all activity carried out through the Account.
3.3 The Customer is solely responsible for creating, managing and revoking Staff Users and assigning their roles. The Owner role holds configuration, billing and full statistics permissions; the Reception role holds operational permissions only. The Customer undertakes to promptly revoke access for personnel who cease to work at the Property.
3.4 The Customer shall notify DevInterface without delay of any suspected unauthorised access to the Account.
4. Configuration, QR codes and Customer Content
4.1 The Customer independently configures the Property profile, the service catalogue, the information content and the documents intended for the AI Assistant. The Customer is responsible for the accuracy, currency and lawfulness of such content.
4.2 The Service generates a QR code for each room or area, containing a non-sequential identifier. The Customer is responsible for printing, placing and replacing QR codes at its premises, and for regenerating the token where it believes the token has been compromised or disclosed outside the room context.
4.3 The Customer is responsible for correctly linking rooms, stay periods and any Guest names entered into the Service. The Service neither requires nor directly collects identifying data from the Guest.
4.4 Within the limits of its Plan, the Customer independently configures the enabling of External sources, the permitted information categories and any domain whitelists or blacklists. The Customer is responsible for the configurations adopted and for the consequences of the third-party information thereby made accessible to its Guests.
5. Relationship with Guests and absence of payments within the Service
5.1 The Service does not process payments or transactions charged to Guests. No payment flow is exposed on the Guest side and the web app provides no checkout functionality.
5.2 Any prices displayed in the catalogue are for information purposes only. Confirmation, delivery and any charging of services requested by Guests take place outside the Service, in accordance with the terms and conditions set by the Customer.
5.3 The contractual relationship concerning hospitality services exists solely between the Customer and its Guests. DevInterface is not a party to that relationship and assumes no liability regarding the performance, quality, availability or price of the services offered by the Property.
5.4 The Customer is solely responsible for accepting and fulfilling requests submitted by Guests through the Service. The Service transmits and organises requests but does not guarantee that they will be read, handled promptly, or fulfilled.
6. Free trial, Plans and fees
6.1 Upon activation, the Service includes a free trial period of 14 days. Thereafter, continued use is subject to payment of the fee applicable to the Plan selected.
6.2 Fees are charged as a flat rate per Property, irrespective of the number of rooms, in accordance with the price list in force at the time of subscription. Prices are exclusive of VAT and any applicable taxes.
6.3 Billing may be monthly or annual, at the Customer’s choice. Fees are payable in advance and are non-refundable for any period already invoiced, save as required by mandatory law.
6.4 Payments are processed through the payment service provider Stripe. No payment instrument data passes through or is stored on DevInterface’s systems: the Customer enters such data exclusively within Stripe-hosted components.
6.5 The Customer may request an upgrade to a higher Plan at any time, effective immediately with proportional adjustment. A downgrade to a lower Plan takes effect from the following billing cycle and entails application of the new Plan’s limits, including the data retention limits set out in Article 8.
6.6 DevInterface may amend the price list upon at least 30 days’ notice to the Customer. New terms apply from the following renewal; a Customer who does not wish to accept them may terminate with effect from the end of the current period.
7. Plan limits, External sources and overage
7.1 Each Plan includes a monthly allowance of calls to External sources, a maximum number of information categories that may be enabled, and specific conditions for general web search. These limits are maximum ceilings: the Customer may reduce them but not exceed them.
7.2 The Service further applies a limit on the number of external searches per individual chat session, configurable by the Customer within the platform-wide maximum, as an anti-abuse measure.
7.3 Graceful degradation. Upon reaching approximately 80% of the monthly allowance, the Customer receives a notification. Upon reaching 100%, external source search is disabled for the remainder of the billing cycle and the AI Assistant continues to respond exclusively on the basis of Customer Content, offering escalation to staff. The Service towards Guests is in no case interrupted. The Customer expressly acknowledges that such degradation constitutes neither a malfunction nor a breach.
7.4 Overage (Max Plan). On the Max Plan only, once the included monthly allowance is exceeded, additional external search consumption is billed on a metered basis, in indivisible packages, in accordance with the price list in force. Overage accrues during the cycle and is charged at month end on the same invoice as the subscription fee, by automatic collection from the registered payment method. No separate invoice is issued.
7.5 Safety cap. Overage does not continue indefinitely: once a configurable maximum threshold is reached, the degradation measures set out in Article 7.3 apply, so as to avoid unexpected charges. The Customer is responsible for configuring its own threshold.
7.6 Usage measurement. The authoritative count for billing purposes is the one recorded by the application. DevInterface performs periodic reconciliations between recorded and invoiced usage. Any dispute regarding usage must be raised within 30 days of the invoice date.
8. Data retention
8.1 The retention period for the history of conversations and requests is determined by the Plan subscribed and constitutes a maximum ceiling, which the Customer may reduce but not extend.
8.2 Irrespective of the Plan, anonymisation or deletion of data at the end of a stay, and the handling of data subject erasure requests, remain permanently active, as set out in the DPA and the Privacy Policy.
8.3 Beyond the applicable retention window, data is deleted or anonymised; only aggregated information not attributable to identifiable individuals continues to feed the statistics.
8.4 In the event of a Plan downgrade, data exceeding the new Plan’s retention window is deleted or anonymised. It is the Customer’s responsibility to export in advance any data it wishes to retain.
9. Customer obligations and responsibilities
The Customer undertakes to:
- use the Service in compliance with the law and with third-party rights;
- not upload content that is unlawful, defamatory, infringing of intellectual or industrial property rights, or containing data it is not entitled to process;
- ensure the accuracy and currency of Customer Content, with particular regard to information on opening hours, prices, house rules and safety;
- provide its Guests with an adequate privacy notice, acting as Data Controller of Guest data, and inform them of the automated nature of the AI Assistant;
- not use the Service for purposes prohibited by the terms of use of third-party providers, in particular OpenAI and Stripe;
- not attempt to access other Properties’ data, circumvent Plan limits, subject the Service to abnormal or automated loads, nor carry out reverse engineering, decompilation or systematic extraction of platform content;
- not resell, sublicense or make the Service available to third parties beyond its own internal use, save under specific written agreement.
10. AI Assistant: automated nature and limitations
10.1 The Customer acknowledges that the AI Assistant’s responses are generated automatically by artificial intelligence models from Customer Content and, where enabled, from External sources, and that they may contain errors, inaccuracies or omissions.
10.2 DevInterface does not warrant the accuracy, completeness, currency or fitness for any particular purpose of the responses, nor the quality of the automated translations generated by the Service.
10.3 The Customer undertakes not to rely on the AI Assistant for information critical to Guest health or safety, including by way of example information on allergens, food intolerances, medical prescriptions, or emergency and evacuation procedures. Such information must be provided directly by Property staff or through dedicated channels.
10.4 The Customer shall supervise the operation of the AI Assistant, periodically review conversation history and correct any Customer Content that generates inadequate responses.
10.5 Information originating from External sources is produced by third parties and transmitted without material modification. DevInterface neither verifies nor warrants its accuracy.
10.6 DevInterface adopts reasonable measures to confine the AI Assistant to the Property’s informational domain and to counter attempts to manipulate its instructions (prompt injection), without however being able to guarantee their absolute effectiveness.
11. Intellectual property
11.1 The software, the ConSergio.ai trade mark, the interface, the documentation and every other component of the Service remain the exclusive property of DevInterface. No rights are transferred to the Customer beyond the licence to use set out in Article 2.
11.2 Customer Content remains the property of the Customer, who represents that it is lawfully entitled to it and grants DevInterface a limited, non-exclusive, royalty-free licence, for the term of the contract only and to the extent necessary to provide the Service — including processing, indexing, automated translation and transmission to the third-party providers listed in the DPA.
11.3 DevInterface may use aggregated and anonymous data derived from use of the Service, not attributable to the Customer or to Guests, for product improvement, internal statistics and benchmarking purposes.
11.4 Save with written authorisation, neither party may use the other’s trade mark or name for promotional purposes.
12. Processing of personal data
12.1 In relation to Guest data processed through the Service, the Customer acts as Data Controller and DevInterface as Data Processor pursuant to Article 28 GDPR. The terms of processing are governed by the DPA, which the Customer accepts together with these Terms.
12.2 In relation to Staff User data processed within the platform, DevInterface acts as Data Processor on behalf of the Customer. In relation to the Customer’s contact and billing data and to service communications, DevInterface acts as an independent Data Controller, as described in the Privacy Policy.
12.3 The Customer acknowledges that the Service relies on sub-processors, listed in the DPA, and undertakes to include the necessary information in its own privacy notice to Guests.
12.4 The Customer is responsible for the lawfulness of the data it enters into the Service, including any Guest names linked to rooms.
13. Service availability and maintenance
13.1 DevInterface adopts reasonable measures to ensure a high level of Service availability, which constitutes a quality objective and not a guaranteed service level with penalties, save as otherwise agreed in writing.
13.2 Interruptions due to scheduled maintenance — ordinarily announced in advance — urgent maintenance, force majeure, cyber attacks or third-party provider malfunctions are excepted.
13.3 In the event of unavailability of the artificial intelligence provider, the Service degrades in a controlled manner: the catalogue, self-service requests and escalation to staff remain available.
13.4 DevInterface performs periodic data backups. The Customer is nonetheless encouraged to export data of interest independently using the export functions available in the panel.
14. Changes to the Service
DevInterface may modify, develop or replace features of the Service for technical, security or product improvement reasons. Where a change entails the removal of a material feature included in the Plan subscribed, DevInterface shall give reasonable prior notice; a Customer who does not wish to accept it may terminate with effect from the date the change takes effect, with a pro-rata refund of the unused portion of the fee.
15. Limitation of liability
15.1 To the extent permitted by law, DevInterface’s aggregate liability towards the Customer, on any ground, is limited to the fees paid by the Customer in the twelve months preceding the event giving rise to liability.
15.2 DevInterface shall not be liable for indirect damages, loss of data, loss of profit, loss of business opportunity, reputational harm or business interruption.
15.3 DevInterface shall in no event be liable for damages arising from: inaccurate or outdated content entered by the Customer; failure or delay in fulfilling Guest requests; reliance on AI Assistant responses in breach of Article 10; External source configurations adopted by the Customer; disclosure or misuse of QR codes or access credentials.
15.4 The limitations in this Article do not apply in cases of wilful misconduct or gross negligence, nor where the law does not permit their exclusion.
15.5 The Customer shall indemnify DevInterface against third-party claims, including those of its own Guests, arising from breach of these Terms or from content and services within the Customer’s sphere of responsibility.
16. Term, withdrawal, suspension and termination
16.1 The contract runs for the subscription period and renews automatically for equal periods, unless notice of termination is given before the end of the current period.
16.2 The Customer may terminate at any time with effect from the end of the period already invoiced, without any right to a refund of amounts paid for that period.
16.3 In the event of non-payment, the Customer enters a grace period, after which the Account is placed in read-only mode: existing data remains accessible, while functions delivering the Service to Guests are suspended. DevInterface may permanently discontinue the Service in the event of persistent non-performance.
16.4 DevInterface may suspend the Service, with prior notice where possible, in the event of breach of these Terms, of use that compromises the security or stability of the platform, or upon request of a competent authority.
16.5 Upon termination of the contract for any reason: QR codes cease to function and it is the Customer’s responsibility to remove them from its premises; the Customer has 30 days to export its data; thereafter, data is deleted or anonymised as provided in the DPA, without prejudice to statutory retention obligations.
17. Changes to these Terms
DevInterface may update these Terms upon notice to the Customer. Material changes are notified with at least 30 days’ prior notice; continued use of the Service after they take effect constitutes acceptance. A Customer who does not wish to accept material changes may terminate with effect from the date those changes take effect.
18. General provisions
18.1 Assignment. The Customer may not assign the contract without DevInterface’s written consent. DevInterface may assign the contract in the context of corporate transactions, upon notice to the Customer.
18.2 Notices. Notices are valid if sent to the e-mail address associated with the Account or, for DevInterface, to the address stated in the preamble.
18.3 Confidentiality. Each party undertakes to keep confidential the other party’s non-public information of which it becomes aware in performing the contract.

These Terms are governed by Italian law. The Courts of Verona, Italy, shall have exclusive jurisdiction over any dispute.
