This document constitutes the General Terms and Conditions of Use (hereinafter, the "Terms and Conditions") that govern access, navigation, use and, where applicable, contracting of services offered through the LETRARIA platform, as well as the rights and obligations derived from the relationships established between users, whether Professionals or Clients.
Access and/or use of the platform, as well as registration as a user, implies reading, understanding and full, express and unreserved acceptance by the user of the entire content of these Terms and Conditions, as well as any other complementary policy or regulation that is duly published and in force on the platform at the time of use.
The User declares to have the necessary legal capacity to contract and be bound by the terms provided in this document, assuming the commitment to use the platform in accordance with current legality, good faith, public order and digital coexistence standards.
Letraria Bookstore is the main platform of LETRARIA, designed to connect independent authors with readers, facilitating the publication, distribution and sale of books in both digital and physical formats.
Letraria Bookstore operates as a specialized book marketplace, where:
Authors registered as Professionals can publish their books on the platform, providing:
Published books are subject to review and approval by LETRARIA before being visible on the platform, ensuring content quality and suitability.
The purchase process in Letraria Bookstore works as follows:
Payments are processed immediately through Stripe, without an escrow system, as books are products delivered instantly (digital) or through physical shipping.
The following economic conditions apply in Letraria Bookstore:
Example: If a book costs 25 EUR, has a 10% commission (2.50 EUR) and printing/shipping expenses of 10 EUR, the author will receive 12.50 EUR (25 - 2.50 - 10 = 12.50). The reader pays only the 25 EUR book price.
LETRARIA, through its administration panel, manages all books published on the platform, being able to:
These settings apply to all future purchases of the book, allowing adjustment of economic conditions according to market needs or specific agreements with authors.
Readers who have purchased a book can leave a review and rating (1 to 5 stars) about it. These reviews help other readers make informed decisions and contribute to the overall quality of the platform.
Reviews must be truthful, respectful and based on real reading experience. LETRARIA reserves the right to moderate or remove reviews that do not meet these criteria.
In compliance with current regulations on information society services and electronic commerce, as well as in compliance with the duty of information provided in Article 10 of Law 34/2002, of July 11, on information society services and electronic commerce (LSSI-CE), users are informed that the ownership of the digital platform LETRARIA corresponds to:

Access to services offered through the LETRARIA platform requires prior user registration by completing the form enabled for this purpose on the website, thus creating a personal account that will allow them to operate as a Client or Professional, as appropriate.
The user undertakes to provide truthful, complete and updated information during the registration process, as well as to keep such information updated at all times. Omission or falsity in the data provided may result in account suspension or cancellation, without prejudice to any legal actions that may correspond.
Every user registered on LETRARIA assumes the following basic obligations:
The platform distinguishes between two types of users, with differentiated functionalities:
Users registered as Professionals must comply with the following additional conditions:
The User, and in particular the Professional, assumes exclusively and unconditionally the responsibility to comply with all their tax, fiscal and legal obligations derived from their activity on the platform, including, without limitation:
LETRARIA acts exclusively as a technological intermediary that facilitates the connection between Clients and Professionals, as well as payment management and invoice issuance for its own intermediation commissions. In no case does LETRARIA assume any responsibility for:
The User indemnifies and holds LETRARIA harmless against any claim, sanction, fine, expense or liability that may arise from non-compliance with their tax, fiscal or legal obligations, including costs and legal expenses that LETRARIA may incur in defense of its interests.
LETRARIA reserves the right to suspend or cancel the account of any User who fails to comply with their tax or legal obligations, or who provides false or incomplete information about their tax situation, without prejudice to any legal actions that may correspond.
The User expressly authorizes LETRARIA to communicate their tax and transaction data to competent authorities when required by applicable regulations (including, without limitation, obligations derived from Directive DAC7 or equivalent regulations).
The user will be solely responsible for the custody and confidentiality of their access credentials (username and password), committing not to transfer them or allow their use by third parties. Likewise, they will be responsible for all activities carried out from their account, exonerating LETRARIA from any liability derived from unauthorized use.
LETRARIA reserves the right to temporarily suspend or permanently delete those accounts that contain false, incomplete information, or whose activity shows fraudulent use or contrary to good faith and these Terms and Conditions.
The measures described in these Terms and Conditions, including the requirements for access to the professional profile, the obligation to provide accrediting documentation, the requirement for work samples, the internal minimum price policy and the powers of suspension or cancellation of accounts, are intended to preserve a professional work environment, avoid intrusion and prevent unfair competition practices within the platform.
In this regard, LETRARIA may:
These actions are understood without prejudice to any legal actions that may correspond in defense of the legitimate interests of LETRARIA and the group of Professionals that make up the platform.
In order to ensure that services offered through the platform are provided by duly qualified professionals, access to certain functionalities—in particular, sending proposals to projects and effective service contracting—will be conditional on prior validation of the professional profile by LETRARIA.
Until LETRARIA has verified and approved the user's profile as a Professional, they will not be able to:
The validation process may include, among other aspects, review of the information provided in the profile, curriculum vitae, professional links, samples of work performed and any other documentation that LETRARIA considers necessary to accredit the professionalism, experience and solvency of the user.
LETRARIA may deny validation or leave it suspended when:
Likewise, LETRARIA may revoke the validation of a professional profile or place it again in pending review status if, subsequently, it detects relevant changes, inconsistencies, conduct contrary to these Terms and Conditions or any other circumstance that puts at risk the trust, service quality or user security.
In order to facilitate the Client's understanding of the level of professionalism of Professionals registered on the platform, LETRARIA may assign each profile an internal rating in the form of stars or other categories visible on the platform.
This rating is based on LETRARIA's own criteria, defined objectively and professionally, which include, among others:
Star categorization is indicative and does not constitute a guarantee of result, nor an official external certification, but rather an internal tool designed by LETRARIA to grant a category of professionalism based on professional merits, experience and conduct within the platform.
LETRARIA reserves the right to review, update, modify or withdraw at any time the rating assigned to a Professional, especially when new merits, relevant changes in their activity, breaches of these Terms and Conditions, or inaccurate information in their profile are detected.
Any attempt to manipulate this categorization system is prohibited, including the provision of false information, fraudulent generation of reviews or any other practice that, in the reasonable judgment of LETRARIA, alters or attempts to illegitimately alter the assigned rating.
The contracting process on the LETRARIA platform begins with the creation of a project by the Client, in which they must describe as accurately as possible the required service, including its typology, objectives, execution deadline and other relevant details for its correct valuation.
At this stage, the Client is not obliged to set a prior budget, as it will be the Professionals who propose their fees in the offers they send through the platform.
The Client may choose between the following publication modalities:
Interested Professionals may send their proposals in relation to the published project.
Proposals sent by Professionals will include, at minimum, a description of the work approach, estimated delivery deadline and total price offered for the service provision. The Client will select the proposal they consider most suitable to their interests among those received through the platform.
After selection, LETRARIA will automatically generate a Service Order Contract, which must be expressly accepted by both parties (Client and Professional) through the platform, formalizing the contractual relationship under the agreed terms.
Minimum Client interaction with proposals
In order to maintain an active environment and avoid the accumulation of inactive projects, the Client commits to maintaining a minimum of interaction with received proposals (for example, opening the proposal, sending messages to the Professional, requesting additional information, marking as "under review", acceptance or rejection).
If 7 natural days elapse since the receipt of the first proposal without any interaction from the Client, projects published as "Public" may be automatically reclassified by LETRARIA as "Private", ceasing to be visible to new Professionals.
For tax and legal purposes, LETRARIA acts as a technological intermediary that facilitates direct contracting between the Client and the Professional. This structure allows guaranteeing traceability, transparency and legality of each operation.
Contractual and invoicing obligations are structured as follows:
Generated documentation:
LETRARIA uses a secure payment system through escrow, managed by the Stripe Connect payment gateway. The Client must pay in advance the full amount of the project, understood as the price offered by the Professional and accepted by the Client through the platform, which will be securely retained until the work has been delivered and approved.
Once the Client validates and approves the work performed, the funds are released in favor of the Professional, previously deducting applicable commissions and taxes. This system guarantees security and transparency in the economic flow between the parties.
LETRARIA makes available to users a private messaging system within the platform, intended exclusively for communication between Client and Professional regarding ongoing projects.
Users commit to using this channel professionally, respectfully and confidentially, refraining from using it for purposes unrelated to the activity developed within the platform.
LETRARIA reserves the right to supervise such communications in a non-intrusive manner, solely for security purposes, fraud prevention or conflict resolution between users, guaranteeing at all times data protection and respect for privacy.
Users have the possibility to register on LETRARIA using their Google credentials. In such case, the user expressly authorizes LETRARIA to access certain basic data from their profile (name, surname and email address) necessary for account creation.
Registration through this modality implies full and unreserved acceptance of these Terms and Conditions, as well as the platform's Privacy Policy.
For the use of the platform and the intermediation provided, LETRARIA will apply a 10% commission to the Client and another 10% to the Professional, calculated on the gross amount of each project managed through the platform.
These commissions allow financing the general operation of LETRARIA's digital ecosystem, including, among others, the following concepts:
These commissions will be visible and itemized during the project contracting, acceptance and payment process, and will be applied automatically once the operation is completed.
Payment management is carried out mainly through the Stripe Connect platform, in accordance with applicable European regulations, in particular Directive (EU) 2015/2366 on payment services in the internal market (PSD2), which guarantees high standards of security, consumer protection and traceability.
Stripe acts as an intermediary payment entity, retaining funds in an escrow system until express validation by the Client regarding the correct completion of the contracted service. Once work delivery is approved, funds are automatically released in favor of the Professional, after deducting the corresponding commission.
In those countries or territories where Stripe Connect is not operational, LETRARIA will enable verified alternative payment methods, which must meet equivalent conditions of security, traceability and regulatory compliance.
Among the alternative methods that may be enabled, subject to verification and validation by LETRARIA, are:
Any alternative method must:
LETRARIA reserves the right to reject methods that do not meet these standards or that present operational, legal or security risks.
In order to protect the value of Professionals' work and avoid unfair competition practices or systematic undervaluation of services, LETRARIA has an internal model for setting minimum price limits.
In particular, LETRARIA reserves the right to:
Repeated offers that consciously and systematically violate these limits may be considered a serious breach of these Terms and Conditions and result in temporary or permanent suspension of the Professional's account.
The Client retains at all times the moral and patrimonial rights over any content, text, idea, manuscript or original document that they contribute to the project commissioned through LETRARIA. Such ownership is not transferred by sharing or incorporating such content on the platform.
The Professional does not acquire any intellectual property rights over the Client's work or over the final result of the commission, once the work is completed and delivered. Their intervention is limited to the provision of the commissioned service, without this attributing to them powers of reproduction, distribution, public communication or transformation over the final result.
Once full payment of the project has been made and correct receipt and approval of the work by the Client has been confirmed, the Professional undertakes to assign to the Client, on a non-exclusive or exclusive basis as agreed, the rights of use, modification, adaptation, reproduction, distribution and publication of the commission result, without territorial or temporal limitation, unless expressly indicated otherwise in the corresponding service order contract.
In ghostwriting or writing on behalf of others commissions, unless otherwise agreed, the assignment of rights will be total, exclusive and without reservation, expressly including the Client's right to publish the work under their own name, without any need for recognition to the Professional as author or co-author of the content.
The Professional declares and guarantees that the delivered work:
The Professional assumes full responsibility in case of claims for infringement of third-party rights, holding LETRARIA and the Client harmless against any legal action, claim or damage derived from such non-compliance.
In order to guarantee transparency, traceability, legal and tax security of relationships between Clients and Professionals, all phases of the contracting process must be carried out entirely through the LETRARIA platform.
Specifically, the following phases are included within the scope of mandatory platform use:
It is strictly prohibited to use the platform as a mere contact channel to establish contractual relationships or payments outside the LETRARIA environment, in order to evade commissions, quality controls, tax obligations or conditions established in these Terms and Conditions.
Any attempt to evade the payment, invoicing or commission systems provided by the platform will be considered a serious breach, which may result in:
LETRARIA reserves the right to conduct internal audits and behavior analysis within the platform to detect patterns of evasion or misuse, applying disciplinary measures in accordance with what is provided in this document.
The Client may request project cancellation depending on the progress status of the commission, in accordance with the following conditions:
The Client may request reasonable revisions or adjustments within the framework of the contracted commission, provided that the modifications are aligned with the previously accepted terms and conditions.
If the Client requires substantial modifications or scope changes that significantly alter the nature, extent or purpose of the initial commission, it will be necessary to formalize a new project and contract, with their corresponding economic conditions and delivery deadlines.
Once the final work has been delivered by the Professional, the Client will have a maximum period of 7 natural days to:
If, after said period, the Client does not issue any response or observation, the system will understand that the work has been tacitly approved, proceeding automatically to release funds to the Professional, in accordance with the escrow system provided.
In case of disagreement between Client and Professional, the parties commit to try to resolve the conflict amicably, using first the internal dispute resolution system offered by LETRARIA.
LETRARIA will act as a neutral mediator, examining the evidence, communications and deliveries made within the platform, in order to facilitate an equitable agreement between the parties. However:
LETRARIA acts as a technological intermediary between Clients and Professionals, providing a digital platform that facilitates contact, project management, payments, invoicing and necessary support for contracting services in the field of letters, editing and production of related content.
In no case will LETRARIA be considered a direct party to the service provision contract entered into between the Client and the Professional, nor will it assume any responsibility for the result, quality, compliance, authorship or legal effects of work performed by Professionals.
LETRARIA's liability is limited exclusively to the following functions:
LETRARIA does not guarantee permanent and uninterrupted availability of the platform, although it commits to adopt all necessary measures to restore service in case of technical interruptions, scheduled maintenance or fortuitous incidents.
Nor will it be responsible for:
LETRARIA informs users that the processing of personal data is carried out in accordance with Regulation (EU) 2016/679 of the European Parliament and of the Council, of April 27, 2016, regarding the protection of natural persons with regard to the processing of personal data and the free movement of such data (GDPR), as well as Organic Law 3/2018, of December 5, on Personal Data Protection and guarantee of digital rights (LOPDGDD).

Before definitive closure of an account by LETRARIA, verification will proceed and, where applicable, compliance with all tax, economic or contractual obligations that may be pending by the user will be required.
Account cancellation does not exempt the user from responsibility derived from actions performed previously, nor does it imply automatic deletion of records that must be kept by legal, tax or accounting imperative.
The user commits to use the LETRARIA platform in accordance with current legality, these Terms and Conditions, and the principles of contractual good faith, professionalism and respect towards other users.
