General Terms and Conditions of Sale

1. Definitions

Quota-Based Offer (or "Offer" or "Campaign"): the conditional sales method in which the purchase contract is concluded, and payment is charged, exclusively upon reaching the minimum number of buyers by the Deadline indicated on the Offer page.

Quota (or "threshold"): the minimum number of participating Customers required for the Offer to be successfully concluded.

Pledge: the expression of intent by which the Customer commits to purchasing the Software under the stated conditions, subject to the condition precedent that the Quota is reached.

Deadline: the date and time the Offer expires.

Customer: anyone who makes a Pledge through the Site.

Consumer: a Customer who purchases for personal purposes, unrelated to their professional or business activity. Both consumers and businesses or professionals may purchase: however, the rights reserved by law to consumers (such as withdrawal and the legal warranty) belong only to the former. A purchase for which the Customer enters a VAT number and requests an invoice addressed to their business is considered to have been made in the capacity of a business or professional.

2. Subject Matter

The Seller sells directly, through the Site, usage licenses for the Software by means of the Quota-Based Offer mechanism. The characteristics, features, technical requirements, compatibility, and interoperability of the Software are described on the Offer page, which forms an integral part of these Terms.

Technical requirements. The Software is a program written in the C language, provided both as source code and as a precompiled binary for Debian 13 [amd64]. The binary requires a Debian 13 system (or compatible Linux distribution) with the OpenSSL 3 library (libssl and libcrypto) installed and a working network connection. Compiling from source requires a C development environment (gcc or clang) and OpenSSL with development headers (libssl-dev package); the remaining dependencies are standard components of the C language and POSIX APIs, generally already present on Linux systems. Up-to-date requirements and installation and compilation instructions are provided on the Offer page.

3. Quota-Based Offer Mechanism

3.1 Offer Conditions

Each Offer indicates at least: the description of the Software and the license; the price (inclusive of VAT for consumers); the minimum Quota; the Deadline; any maximum number of Pledges. For the current Campaign:

3.2 Pledge and Payment Authorization

By making the Pledge, the Customer submits a binding purchase offer, subject to the condition precedent that the Quota is reached by the Deadline.

At the time of the Pledge, no amount is charged: the Customer hereby authorizes the charging of the price to the payment method provided, which will be securely stored (or pre-authorized) through the payment processor, subject to strong customer authentication (SCA/3D Secure) where required by payment services regulations. Such authorization constitutes a mandate to charge the amount indicated in the Offer, to be carried out upon occurrence of the conditions set out in Section 3.3, without any further action required from the Customer, except where the issuing institution requires additional authentication. The Customer guarantees the validity and sufficient funds of the payment method until the conclusion of the Offer.

3.3 Conclusion of the Contract, Charge, and Delivery

Pledges remain open until the Deadline, even after any early achievement of the Quota. At the expiry of the Deadline, if the Quota has been reached, the Offer concludes successfully and the contract is automatically finalized between the Seller and each Customer with an active Pledge, with no need for further confirmation. Only at that point is the amount due charged and the Software delivered as set out in Section 5. The Customer receives, by email on a durable medium, the order confirmation with a summary of the terms and of the declarations made pursuant to Section 6.

The Seller sends each Customer a reminder by email 48 hours before the Deadline expires, indicating any upcoming charge. The outcome of the Offer is in any case communicated by email to all participating Customers.

3.4 Failure to Reach the Quota

If the Quota is not reached by the Deadline, the Offer automatically lapses: no contract is concluded, no amount is charged, and the stored payment method is removed. Any pre-authorizations will be released within the technical timeframes set by the payment network and the Customer's bank, at no cost to the Customer.

3.5 Withdrawal of the Pledge

The Customer may freely withdraw their Pledge at any time until the Deadline expires, by writing to luca@lucaercoli.it or through any features available on the Site: in such case, the stored payment method is removed and nothing is charged. After the Offer has concluded, withdrawal is no longer possible and the provisions on withdrawal set out in Section 6 apply instead.

3.6 Cancellation of the Offer

The Seller may cancel an Offer before its conclusion, with nothing charged to Customers, as well as afterward in the case of manifest errors (for example, a clearly incorrect price) or a supervening impossibility to provide the Software. In the event of cancellation after charges have already been carried out, Customers are entitled to a full refund of amounts paid.

3.7 Failed Charge

Should the charge fail (for example: a request for additional authentication from the issuing institution, insufficient funds, or an expired or blocked payment method), the Customer will receive a request to complete or resolve the payment within 48 hours. If this deadline passes without action, the order is deemed cancelled. Should, as a result of such cancellations, the number of Customers with a successful payment fall below the Quota, the Seller may, at its discretion, either proceed with the contracts already concluded or cancel the Offer, with a full refund of the amounts charged to the other Customers.

3.8 Integrity of Offers

It is prohibited to artificially manipulate the achievement of the Quota, for example through multiple accounts or Pledges attributable to the same individual, or through automated tools. Fraudulent Pledges may be cancelled at any time.

4. Prices, Payments, and Invoicing

The prices indicated are inclusive of VAT for consumer Customers. Payment services are provided by Stripe: the complete payment method data is handled directly by the processor and is not stored by the Seller.

4.1 Requesting an Invoice

The invoice is issued upon the Customer's request. The request is made through the dedicated portal https://security.lucaercoli.it/my_invoice.php: by entering the email address used for the purchase, the Customer receives a personal link to fill in the billing details — for individuals, the tax code; for businesses and professionals, the VAT number and the SDI recipient code or PEC address; and, for everyone, the full billing address. The request should preferably be made at the time of purchase and in any case within [7] days of the charge.

4.2 Accuracy of Data and Corrections

The Customer is responsible for the accuracy and completeness of the billing data provided. The data may be independently modified, via the same personal link, until the request is taken into processing for issuance; after that, corrections and changes are possible only within the limits and in the forms provided for by tax regulations (credit/adjustment notes).

4.3 Issuance and Delivery

The invoice is issued in electronic format and transmitted through the Exchange System (Sistema di Interscambio) of the Italian Revenue Agency, delivered according to the SDI recipient code or PEC address indicated; for consumer Customers, the invoice is in any case available in the reserved area of the Revenue Agency. A courtesy copy is sent to the email address used for the purchase. Issuance takes place on a deferred basis, within the terms provided by law.

5. Delivery and License to Use

Delivery of the Software takes place exclusively in digital form (download link), immediately after the conclusion of the Offer and the successful completion of the charge, to the email address provided by the Customer, and includes: the complete source code in the C language; the precompiled binary for Debian 13 [amd64]; the full text of the license (LICENSE file).

The Software is released to the Customer under an MIT license, the text of which is included in the delivered package and prevails, with regard to rights over the Software, over any conflicting clause. Under this license, the Customer may freely use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the Software, including for commercial purposes, with the sole condition of retaining the copyright notice and the license text in copies or substantial portions of the Software.

The license contains the customary warranty disclaimer of permissive licenses (provided "as is"). This clause does not affect, with respect to the consumer Customer, the legal warranty of conformity owed by the Seller pursuant to Section 8, within the limits and subject to the deviations set out therein and validly accepted.

6. Right of Withdrawal

The consumer Customer has the right to withdraw from the contract within 14 days of its conclusion (i.e., from the closing of the Offer once the Quota is reached), with no obligation to state a reason, by explicit statement sent to luca@lucaercoli.it, including by using the standard form set out in Annex I, Part B, of the Italian Consumer Code.

Loss of the right of withdrawal (digital content): since this involves the supply of digital content on a non-tangible medium, the consumer loses the right of withdrawal, pursuant to Section 59, paragraph 1, letter o), of the Consumer Code, where: (i) they have given their prior express consent to the immediate supply of the Software during the withdrawal period; (ii) they have, at the same time, acknowledged that, once supply begins, they lose the right of withdrawal; (iii) supply has actually begun with the Software being made available following the conclusion of the Offer.

Such consent and acknowledgment are collected at the time of the Pledge through a specific and separate statement, distinct from acceptance of these Terms and from the payment authorization, and are referenced in the order confirmation. Since the Site provides exclusively for immediate supply of the Software upon conclusion of the Offer, giving such consent is a necessary condition for completing the Pledge.

7. Refunds

Refunds due (for withdrawal, cancellation of the Offer, or other causes) are carried out by the Seller by crediting the same payment method used, with no additional cost to the Customer and without requiring any new authentication from the Customer, within 14 days of the withdrawal notice or the event giving rise to the right to a refund. The time it takes for funds to actually become available depends on the payment network and the issuing institution. Where crediting to the original method is not technically possible, the refund will be made by another means agreed with the Customer, at no cost to them.

8. Support and Warranty

8.1 No Support Service

The Software is sold without any support service: the Seller does not provide, whether for payment or free of charge, technical support, help with installation or compilation, training, maintenance, bug fixes, updates — including security updates — or new versions of the Software. The address luca@lucaercoli.it is intended exclusively for complaints and for exercising the rights provided by law or by these Terms.

8.2 "As Is" Supply and Deviation from Objective Conformity Requirements

The Software is provided as a single act of supply, "as is", in the condition it is in at the time of delivery, as source code and binary accompanied by the MIT license. The Customer is specifically informed that the following characteristics deviate from the objective conformity requirements set out in Section 135-decies of the Consumer Code: no updates are provided, including security updates, nor new versions; continuous, stable, or error-free operation of the Software is not guaranteed, nor is compatibility with future versions of operating systems, libraries, or environments other than those indicated on the Offer page. The consumer expressly and separately accepts these deviations at the time of the Pledge, through a specific statement distinct from acceptance of these Terms; giving such acceptance is a necessary condition for completing the Pledge.

8.3 Consumer Legal Warranty

The mandatory rights provided for consumer Customers under Sections 135-octies et seq. of the Consumer Code remain unaffected, with respect to defects of conformity existing at the time of supply, relative to what is described on the Offer page, that become apparent within two years of supply — within the limits of the deviations validly accepted pursuant to Section 8.2. In such cases, the consumer is entitled to the remedies provided by law: restoration of conformity or, in the cases provided for, a reduction of the price or termination of the contract.

8.4 Professional Customers

With respect to businesses and professionals, the Software is sold exclusively "as is" and "as available": all warranties, express or implied, are excluded, including the warranty against defects and lack of quality under Sections 1490 et seq. of the Italian Civil Code and any warranty of merchantability, fitness for a particular purpose, stability, or absence of errors, with only the MIT license remaining in effect. Except in cases of willful misconduct or gross negligence, all liability of the Seller is excluded and, in any case, limited to the amount paid by the Customer.

9. Proper Use of the Site

It is prohibited to: interfere with the operation of the Site or its security systems; carry out scraping, unauthorized access, or cyberattacks; create multiple accounts or Pledges to manipulate Quotas; use automated tools to submit Pledges. The Seller may suspend accounts involved in such conduct and cancel the related Pledges, without prejudice to compensation for damages.

10. Site Availability and Limitations of Liability

The Seller strives to keep the Site operational, but does not guarantee the absence of interruptions or malfunctions, including those due to maintenance, technical issues, force majeure, or service failures by third-party providers (hosting, payment services, email).

To the maximum extent permitted by law, and except in cases of willful misconduct or gross negligence, the Seller is not liable for indirect damages arising from use or inability to use the Site. In any case, the mandatory rights granted to consumers by law remain unaffected, including those concerning withdrawal, refunds, and the legal warranty.

11. Privacy

The processing of Customers' personal data is governed by the Privacy Policy published on the Site, which the Customer is invited to read before making a Pledge.

12. Changes to the Terms

The Seller may modify these Terms at any time, by publishing them on the Site. Changes do not apply to Pledges already submitted nor to contracts already concluded, to which the Terms accepted at the time of the Pledge continue to apply.

13. Governing Law and Competent Court

These Terms are governed by Italian Law. For any dispute, the Court of Frosinone 03100 (FR), Italy shall have exclusive jurisdiction, except for the mandatory consumer forum where applicable. The consumer's right to resort to out-of-court dispute resolution procedures provided for under Sections 141 et seq. of the Consumer Code remains unaffected.
