AccesPub general terms and conditions

Version 2.2 · in force from 6 November 2026 · new: scope of the conformance statement, laws of other countries and no legal advice (clause 12) · English translation for information; the Spanish version is binding

These terms govern all AccesPub services: self-service at accespub.app, the portal and API at api.accespub.app and the managed service (Enterprise). Part I applies to all of them; Parts II, III and IV apply to each channel.

Part I. Common terms

1. Who provides the service

Alberto Barajas González, self-employed professional trading as ab serveis, Spanish tax ID 46629726D, Joan Miró, 19 — 08319 Dosrius (Barcelona), Spain (the "Provider"). Contact: info@abserveis.net.

If the contract is assigned to a company under clause 15, references to the Provider shall be understood as references to that company from the date the assignment takes effect.

2. Services and structure of these terms

AccesPub is a service for analysing and fixing the accessibility of e-books in EPUB format. It is offered through three channels:

Part I applies to all channels. In case of conflict, the following order prevails: (1) the quote, order or specific agreement signed by both parties; (2) the channel's specific part; (3) Part I. Where applicable, the data processing agreement (DPA) and the privacy policy form part of the contract.

3. Who it is for

The service is intended only for companies, professionals and organisations contracting it for their professional activity, including authors who publish and sell their own works (the "Client"). By accepting these terms, the Client declares that it contracts in that capacity and that the person accepting has authority to bind the organisation they represent.

If, despite that declaration, the Client is legally a consumer, the consumer protection rules that cannot be excluded by contract shall apply and prevail over any clause of these terms that contradicts them.

4. Electronic contracting and acceptance

• The Client expressly accepts these terms before paying or starting to use the service, by ticking the acceptance box of the relevant channel or by signing the quote or order that refers to them. Without that acceptance the service is not provided.
• Before confirming the purchase, the Client can review the order details and correct any error in the payment form or in the quote.
• The Provider records and keeps the accepted version of the terms, the date and time and the identifier of the order, the code or the person who accepted. The Client may request a copy at any time.
• After payment, the Client receives the confirmation and the invoice by email.
• The contract is concluded in Spanish. Translations into other languages are for information only.

5. What the service includes and what it does not

• Automatic accessibility analysis and fixing of e-books in EPUB format. The supported types of EPUB are stated at accespub.app and in the documentation; for now, only reflowable EPUB: fixed-layout EPUB files are rejected on upload and use no credits.
• Tools for a person to review what requires judgement: image alternative text, tables, languages and metadata.
• Validation with EPUBCheck and generation of the fixed EPUB, its accessibility report and the ONIX 3.1 accessibility record. Depending on the channel, also commercial metadata, commercial ONIX, the GEO Kit and optional publication of the book record in the Titularium catalogue.
• It does not include manually fixing EPUB files the tool cannot fix, which ab serveis may quote separately, nor auditing or certifying accessibility (clause 12).

6. Prices, credits and payments

• The service is paid in advance through credit plans or, for the managed service, as quoted. Current prices are those published at accespub.app or those in the accepted quote.
• Prices exclude VAT, which is added to the invoice where applicable. Reverse charge applies to clients in other EU Member States with a valid EU VAT number.
• How credits are used is described in each channel's specific part. Credits belong to the Client that buys them: they cannot be transferred to third parties or exchanged for money. Using credits to remediate third parties' books as part of a service is only allowed in the channels that provide for it (clause 22a and clause 30a).
• Validity: credits expire after 24 months without activity, that is, without the Client buying or using credits. Each purchase or use restarts the period, unless the channel's specific part sets a different period. Expired credits are not refunded.
• Refunds: unused credits are not refunded, unless the law requires it or the Provider cannot provide the service for reasons attributable to it, in which case the proportional part of the unused credits is refunded.
• The Provider may change the prices of future plans. Credits already purchased keep their value.

7. Artificial intelligence

• Some features offer suggestions generated with artificial intelligence (alternative text, table captions, blurbs, subjects and keywords). To generate them, the necessary images or text excerpts are sent to the AI provider.
• The current provider is Google (Gemini), in its paid tier, whose terms prevent that content from being used to train its models.
• Suggestions are only suggestions: they are not applied unless a person reviews and accepts them, and they may contain errors. Whoever accepts them takes responsibility for their content.

8. Client obligations

• To hold all the rights and permissions needed over the files it sends for the Provider to process and modify them for accessibility purposes. If the files belong to a third party, those rights include the express authorisation of their owner. The Client shall hold the Provider harmless against third-party claims based on the Client not holding those rights.
• Not to send unlawful content, malicious code or files that are not e-books, nor attempt to circumvent the limits, the security of the service or the separation between clients.
• To keep its access codes, passwords and API keys safe and to inform the Provider immediately if it suspects unauthorised use. Whatever is done with them is attributed to the Client.
• To review the result before publishing it and to keep its original files: the service is not an archiving system.

9. Intellectual property

• The Client keeps all rights to its books and to the results generated from them (EPUB, reports, ONIX, GEO Kit).
• The Client grants the Provider a non-exclusive, free, worldwide licence, limited to the time needed, to store, reproduce and modify the files for the sole purpose of providing the service contracted.
• The Provider may use aggregated, anonymous technical data (types of errors, processing times, number of images) to maintain and improve the service. It never uses the content of the books for other purposes or to train AI models.
• AccesPub, its code, its documentation and the AccesPub, Titularium and ab serveis brands belong to the Provider.

10. Confidentiality

The Provider treats the files and information it receives from the Client as confidential, including unpublished books. It only accesses them when needed to provide the service, resolve an incident or handle a help request from the Client, and does not disclose them to third parties except to the providers the service needs or where required by law.

11. Data protection

• Contact data and data of the Client's users are processed under the privacy policy.
• As regards personal data the books may contain, the Client is the controller and the Provider acts as processor under the data processing agreement (DPA), which forms part of this contract. The providers involved are listed in the sub-processor list.
• File retention periods are set out in each channel's specific part.

12. Scope of conformance and warranties

• AccesPub automates technical fixes and helps prepare EPUB files intended to meet the European Accessibility Act (EAA), its Spanish transposition, EPUB Accessibility 1.1 and WCAG 2.1 AA, but it does not certify or guarantee that an EPUB is fully accessible or that an authority, a distributor or a buyer will consider it conformant. Automated checks do not detect every issue, and the quality of alternative texts, the clarity of the content or the accessibility of complex layouts require human judgement.
• The conformance statement is the Client's. The EPUB's accessibility metadata and the report record the statement the Client makes as publisher or rights holder, based on the automated checks and on the human review the Client carries out or commissions. It is not a certification by ab serveis or by any third party. It is only included when EPUBCheck finds no errors in the final EPUB and no items remain pending human review. Final verification, the decision to publish and maintaining that statement are the Client's.
• Other laws and other countries. AccesPub is based on European law and the technical standards listed above. ab serveis does not guarantee that the result meets the laws or standards of other countries (for example, in the United States, the ADA or Section 508 of the Rehabilitation Act), or the specific requirements of distributors, platforms or public or private buyers. Checking this is the Client's responsibility.
• No legal advice. Reports, notices, validation results and help texts are technical information to assist the Client; they are not legal advice.
• The service is provided with reasonable means, but without a guarantee that it will work without interruptions or errors, and without warranties other than those imposed by law or set out in these terms.

13. Liability

• The Provider is liable for damage it causes by breaching these terms.
• Except in cases of wilful misconduct or gross negligence, and to the extent the law allows it to be limited, its total liability to the Client for all claims arising from the contract is limited to the amount paid by the Client in the 12 months before the event giving rise to it.
• On the same terms, the Provider is not liable for loss of profit or indirect damage, for the loss of files the Client was required to keep (clause 8), or for penalties or claims arising from a book published by the Client not complying with accessibility rules.
• Nor is it liable for failures of third-party services it does not control (hosting, AI, payments, email), without prejudice to its duty to act diligently to restore the service.

14. Suspension and termination

• The Client may stop using the service at any time by writing to info@abserveis.net.
• The Provider may suspend access, notifying the Client, in case of use contrary to these terms or a risk to the security of the service or other clients; and may terminate the contract if the breach is not remedied within 15 days of the notice. In that case no credits are refunded.
• If the Provider stops providing the service, it will give at least 60 days' notice. From the notice, no new credits are sold and the Client may keep using the credits it has until the closing date. On closing, the Provider will refund the proportional part, at the price per credit the Client paid, of the credits still unused and not expired.

15. Assignment of the contract and change of owner

• To a company of the Provider. The Client hereby consents to the Provider assigning its position in this contract, with all its rights and obligations (including credits, codes, organisations, data and the DPA), to a company it incorporates and of which it is the sole or majority shareholder or a director. The assignment requires no new consent or new signed document: it takes effect on the date stated in the notice the Provider sends by email or publishes in the service, which shall be at least 15 days after the notice.
• To a third party acquiring the business. The Provider may also assign the contract to whoever acquires the AccesPub service or the ab serveis business, giving at least 30 days' notice. If the Client does not agree, it may terminate the contract before the effective date and receive the proportional part of the unused credits.
• In both cases, the assignee fully assumes the Provider's obligations, the service continues on the same terms and credits keep their value. From the effective date, invoices are issued by the assignee.
• The Client may not assign the contract or its credits without the Provider's written consent.

16. Changes to these terms

• The Provider may amend these terms. It will publish the new version with its date and give at least 30 days' notice through the means stated in each channel's specific part.
• If the Client does not agree, it may terminate the contract before the effective date and receive the proportional part of the unused credits. If it continues to use the service afterwards, the new version applies.
• Changes that only benefit the Client or are required by law may apply sooner.

17. Force majeure

Neither party is liable for failures caused by events beyond its reasonable control that it could not foresee or avoid, for as long as they last.

18. Notices

Notices are sent to the email address the Client provided when contracting (or to its organisation's administrators in the portal) and, to the Provider, to info@abserveis.net. The Client must keep that address up to date.

19. Severability

If a clause is declared void, the rest of the contract remains in force and the void clause is replaced by the valid one closest to its purpose. A party's failure to enforce a right does not mean it waives it.

20. Governing law and jurisdiction

These terms are governed by Spanish law. For any dispute, the parties submit to the courts of Barcelona, unless a mandatory rule provides for another venue.

Part II. Self-service (accespub.app)

21. Purchase and access code

• Self-service plans are bought through each plan's payment link (Stripe). Before paying, the Client ticks the box accepting these terms in the payment form.
• Plans not sold through a payment link (trials for publishers, volume plans) are contracted with ab serveis, which delivers the code after payment or agreement.
• The plan entitles the Client to an access code with a number of credits. When activating the code at accespub.app, the Client again expressly accepts the version of these terms in force at that time, which is the one that applies to that code.
• Whoever holds the code can use its credits: the Client must keep it safe. If it is lost, ab serveis can send it again to the purchase email address.

22. Use of credits

• One credit is deducted the first time the fixed EPUB of a session is downloaded. Analysing, reviewing, validating and downloading it again in the same session use no credits.
• Uploading the same book again in a new session, or a different version, is treated as a new book.
• Credits from a free trial may be withdrawn when the agreed period ends.

22a. Use for own works

• Self-service is for the Client to remediate its own works: those it has authored or those it publishes or sells under its own publishing imprint, including those of its imprints and co-editions it takes part in.
• It may not be used to provide third parties, whether paid or not, with ebook remediation, conversion, layout or accessibility services, or to process other publishers' or authors' books on their behalf. The portal and the API (Part III) are for that: they include the terms for service providers and the data processing agreement that such use requires.
• The Provider may ask the Client for reasonable information about the ownership of the books processed with a code. If it finds a use contrary to this clause, it will tell the Client and give it 15 days to choose between: (a) moving to the portal and the API, paying the price difference for the credits already used for third parties at the current rate of the equivalent plan; or (b) terminating the contract, with a refund of unused credits at the price paid. If the Client does not choose, the Provider may suspend the code.
• This clause does not prevent a person or entity from occasionally helping an author, free of charge, to use the author's own code.

23. Limits and retention

• Maximum size: 50 MB per EPUB, temporarily extendable to 200 MB at the Client's request.
• Each session's files are deleted automatically after 24 hours of inactivity. The Client must download the EPUB, the report and the metadata in time. The Provider keeps no copies.

24. Titularium catalogue (optional)

If the Client chooses to publish a book record in the Titularium catalogue, it authorises the Provider to display publicly the metadata and cover the Client itself reviews and confirms, for the sole purpose of promoting the book. It can ask for it to be removed at any time.

25. Consumers

If the Client is a consumer (clause 3), it may withdraw from the purchase within 14 days as long as it has not used any credit. By downloading the first EPUB it expressly requests that the service be provided immediately and acknowledges that it loses the right of withdrawal for the credits used.

26. Notice of changes

Changes to these terms are announced at accespub.app and by email to the purchase address, where known. Each code is governed by the version accepted when it was activated, unless the Client accepts a later version.

Part III. Portal and API (api.accespub.app)

27. Sign-up and acceptance

• The Client requests sign-up through the sign-up form, giving the organisation's and billing details and the plan, and accepts these terms and the DPA before sending it. It may also accept them by signing the quote or order that refers to them.
• ab serveis issues the invoice or quote. Credits are assigned to the organisation once payment is received, and the administrator is then invited.
• When accepting the invitation, the administrator confirms acceptance of these terms on behalf of the organisation. If a new version is published, they will be asked to accept it when they sign in to the portal.
• The Client is responsible for the people it invites, their roles and the safekeeping of their passwords and API keys.

28. Use of credits

• One credit is deducted the first time a title with up to 150 images is finalised. Each additional block of 150 images (or part of one) uses another credit; the portal and the API warn about this before the review starts.
• No credits are used by titles that fail, by finalising an already finalised title again, by AI suggestions or by use with test keys (ap_test_). A new version of an EPUB is treated as a new title.
• Credits belong to the organisation and expire 12 months after purchase (each grant of credits has its own period); the oldest are used first. Credits from a pilot are governed by what was agreed for that pilot and may be withdrawn when it ends.

29. Usage limits

Unless otherwise agreed: 50 MB per EPUB (up to 200 MB with prior approval), 50 EPUB files and 1 GB per batch, and 5 GB of storage per organisation. The API applies per-minute request limits, published in the documentation. ab serveis may raise them at the Client's request.

30. Review and reviewers' responsibility

Review decisions are recorded under the name of the person who takes them. The Client is responsible for the identity and competence of its reviewers, including any external reviewers it invites.

30a. Service providers

• The Client may use the portal and the API to provide remediation services to its own clients (publishers, authors or other entities), and freely set the price it charges them.
• Accounts, keys and credits are not transferable. The Client's clients may only access the portal as reviewers invited by the Client, acting under its responsibility (clause 30). The Client may not resell access to the portal or the API as its own product or offer it under another brand without a written agreement with the Provider.
• Rights and data. Before uploading a client's files, the Client must have the authorisation of the rights holder (clause 8) and, if they contain personal data, that of the controller, under section 5 of the DPA.
• Brand. The Client may truthfully state that it uses AccesPub (for example, "remediated with AccesPub"), but may not present the results as a certification or a guarantee by the Provider (clause 12) or imply that it is a partner, official distributor or representative of the Provider without a written agreement.
• Liability towards its clients. The Client is solely responsible for the service it provides to its clients and for what it promises them. Its clients acquire no rights against the Provider under this contract. The Client shall hold the Provider harmless against claims by its clients arising from that service, unless they are due to the Provider's wilful misconduct or gross negligence. Between the Client and the Provider, the limits of clause 13 apply.
• Support. Help requests are submitted by the Client; the Provider does not deal directly with the Client's clients.
• This clause creates no agency, distribution, exclusivity or representation relationship between the parties.

31. File retention

EPUB files are deleted 30 days after each title is finalised. On termination, data are returned and deleted under the DPA.

32. Support and notices

Support is provided through the portal's help requests, on working days. Service email notices never include the content of books or requests: everything is consulted in the portal. ab serveis does not guarantee a specific availability level unless agreed in writing, and will give advance notice of scheduled downtime.

33. Changes to the API

ab serveis may improve the API. Backward-incompatible changes will be announced in the documentation and by email to administrators at least 30 days in advance, unless required for security reasons.

34. Notice of changes to these terms

Changes to these terms are announced by email to each organisation's administrators and in the portal, with the notice period in clause 16.

Part IV. Managed service (Enterprise)

35. Quote and acceptance

ab serveis prepares a per-title quote based on the number of images, with the delivery time and payment terms. The Client accepts the quote and these terms by signing it or accepting the acceptance form that accompanies it, before work starts.

36. Performance

• The Client sends the EPUB files through the AccesPub portal or another secure channel stated in the quote; not by email.
• ab serveis applies the automatic fixes and carries out the human review of each image and the other items that require judgement, with AI help where useful.
• Delivery times are those in the quote and start once the files and, if agreed, the advance payment have been received.

37. Delivery and acceptance

• The Client has 15 days from delivery to review the result and report any issues, which ab serveis will fix at no cost if they are due to its work. After that period without issues, the delivery is deemed accepted.
• ab serveis writes alternative texts with professional diligence, but the Client knows the meaning of its books best: it must check the result before publishing it. Clause 12 on the scope of conformance applies.

38. Retention

The Client's files are deleted 30 days after the delivery is accepted, unless the quote states otherwise.
