This is a translation: in the event of any discrepancy, the Italian version prevails.
The ComputoLab software and this website are supplied by Fausto Maria Demetrio s.p., a sole trader with its registered office at Vojkovo nabrežje 17, 6000 Koper / Capodistria (Slovenia), VAT number SI16258380 (hereinafter “the Provider”). By using the website or the software you accept these terms.
The subject matter of the contract is exclusively the licence to use the ComputoLab application. The Provider does not sell, resell or distribute for a fee any third-party content, databases or publications: no price list is sold, either individually or as a component of the subscription (see article 6).
ComputoLab is licensed, not sold. The free version (“Free”) may be used for an unlimited time with the limitations set out on the website (1 project, PDF printing with a watermark). The “Pro” subscription unlocks the additional features described on the Pricing page; the “Multi-workstation licence” extends Pro to several computers and collaborators. The licence is personal and tied to the number of workstations provided for by the plan; the individual Pro may be used by the same user on Mac and Windows.
The Pro subscription renews automatically on expiry, unless cancelled before the renewal. When a subscription expires the app reverts to the Free features without deleting the user's data: projects remain openable and printable to PDF with a watermark.
Job data belongs to the user and stays on the user's computer. ComputoLab works without a connection and does not keep projects on the Provider's servers: no document depends on the availability of an online service.
The Provider guarantees that in every version of the application, including the free one and including expired licences, the following remain available at no additional cost:
ComputoLab.clabproj file: a self-contained JSON with
all the project's tables, the photographs and the attachments;.clabarchivio file, also
in JSON format;The documents produced by the program (bills of quantities, SAL progress reports, accounting registers, certificates) are PDF/A-2b files, the ISO 19005-2 format for long-term preservation: they remain readable and preservable to standard regardless of the software that generated them.
The Provider undertakes not to introduce, in subsequent updates, changes that make data already entered inaccessible or exportable only for a fee. Should the supply cease, the Provider will give notice at least 90 days in advance on this website and at the email address associated with the licence; the export functions listed above continue to work even after that date, because they require no connection to the Provider's servers.
For supplies that require it, the Provider is willing to consider depositing the source code with a trusted third party (escrow), on terms and at a cost to be agreed with the client.
Payments are processed by Paddle.com Market Ltd., which acts as Merchant of Record (authorised reseller) and issues the corresponding invoice. Paddle's terms also apply to the transaction.
Supplies to Italian public bodies, with purchase order, electronic invoice and CIG, are handled by the national distributors.
The public authorities' price lists made searchable by the application (regional and autonomous-province price lists, Prezzario Unico del Cratere) are documents published by the bodies that issue them, which remain their owners. Documents whose owners expressly reserve reproduction rights are not included: for those, the user may import their own copy, downloaded from the body's website. ComputoLab makes them available in structured, searchable form within the application, free of charge and in all versions, Free included: they are not a product for sale, they are not conditional on the subscription and their value does not contribute to the price of the licence. The user may at any time obtain the same documents from the body that publishes them.
Re-use is based, for price lists published under an open licence, on that licence itself (the licences declared by the bodies are indicated on the pages of the individual price lists, together with the relevant attribution); for the others, on art. 52, comma 2, del D.Lgs. 82/2005 (Codice dell'amministrazione digitale), under which data and documents published without the express adoption of a licence “are deemed to be released as open-type data”, and on art. 1, comma 1, lettera l-ter) of the same Code, which defines open data as usable “by anyone, including for commercial purposes”. D.Lgs. 36/2023 (art. 41 and Allegato I.14) provides that regional price lists are to be made available free of charge and in open data format. In every case the Provider indicates the body that publishes the document, the act of approval and the link to the official source.
The user may also import their own price lists or those of third-party publishers for which they hold a valid licence: such files remain on the user's device, they are not transmitted to the Provider nor redistributed. The Provider does not sell or resell price lists or databases of third-party publishers. Price lists of manufacturers or publishers that may be included in the application's catalogue are made available free of charge, under the written authorisation of the rights holder or the licence under which they are published, as stated on the page of each price list, and do not contribute to the licence price.
Decompiling, redistributing or reselling the software and circumventing the licensing systems are prohibited. The software is a support tool: responsibility for the correctness of measurements, documents and professional obligations remains with the user.
The software is provided “as is”. To the extent permitted by law, the Provider is not liable for indirect damage or for damage arising from errors in the data entered by the user or in imported third-party price lists.
The Provider may update these terms by publishing the new version on this page. These terms are governed by Slovenian law; the courts of Capodistria (Koper) have jurisdiction, without prejudice to the mandatory consumer protection rules of the purchaser's country of residence and to the courts provided for by them. The purchase contract is concluded with Paddle as Merchant of Record and is also governed by Paddle's purchase terms.
