Lex · terms of use.

These Terms of Use govern the use of Lex by ALMA ("Lex") at lex.alma.dev and in the Lex app for iPhone, iPad and Mac. Please read them carefully: you must accept them to create an account. How we handle your personal data is set out in the Lex Privacy Policy.

1. Who we are

Lex is provided by Albuquerque de Matos, Unipessoal, Lda (ALMA), NIPC (tax and company number) 516746596, address Rua Canto da Maya 1, 8.º, 1070-372 Lisboa, Portugal.

Contact: support, support@alma.dev; legal and privacy matters, legal@alma.dev. More about ALMA in Legal information.

2. What Lex is

Nature of the service. Lex is a tool for legal research and legal information. ALMA is not a law firm or a firm of solicitadores, does not provide legal consultation (consulta jurídica) or representation, and does not perform acts reserved to lawyers or solicitadores (Portuguese Law 10/2024 of 19 January). Using Lex does not create a lawyer-client relationship or a mandate.

Answers are generated automatically by artificial intelligence systems from Lex's sources and are not reviewed by people; they may contain errors or omissions or be out of date. Quotes are compared automatically with the stored text of the sources and those that are not found are flagged, but the interpretation is not checked. Always check the official sources before using an answer, especially in court filings. For advice on a specific case, consult a lawyer or solicitador.

Lex shows provisions, decisions and legal scholarship and explains them in general terms. It is not meant to analyse the specific case of the person using it, tell you what to do in your situation, predict the outcome of a case of yours, or prepare documents for you to sign or file with a court or any other body.

Intended purpose. Lex is intended for legal research by legal professionals, students and researchers. It is not intended to be used by courts, other judicial authorities, arbitral tribunals, julgados de paz (local courts of limited jurisdiction) or alternative dispute resolution bodies to examine or decide cases, nor to assess students or take automated decisions about people.

The collection. Lex holds copies of published official texts (Portuguese and European Union legislation, case law and legislative initiatives) and references to legal scholarship, and keeps them up to date from the official sources. Each document shows its source and official link. Coverage is not complete and updates may lag: the version with official value is the one published by the official source (for example, the Diário da República). Lex does not guarantee that a provision is in force, that a decision has not been changed or overturned, or that the collection includes the latest changes; it does not track deadlines and does not tell you about changes made after your search.

Professional use. If you use Lex in your professional activity, Lex is a tool that supports your research and does not replace your professional judgement. You alone are responsible for the opinions and advice you give, the pleadings and documents you draft or file, checking the provisions, decisions and quotes you use, keeping track of deadlines and complying with your professional and ethical duties.

3. Your account

• Age. To create an account you must be at least 16. People under 16 cannot have a Lex account.
• If you are 16 or 17, you may only create the account and use Lex with the agreement of your parents or legal guardian. They are also responsible for any purchase you make. Purchases are only made on the App Store (section 9), where Apple's family settings, such as Ask to Buy, apply.
• If you are already an adult, you must have the capacity to enter into contracts.
• Give accurate details and keep your email up to date: it is how we contact you.
• Each account belongs to one person. Don't share your password.
• Keep your password safe and, if you can, use a passkey. If you suspect someone has used your account, change your password and tell us at support@alma.dev.

4. Acceptable use

When using Lex, you must not:

• extract, copy or download the collection systematically or by automated means (for example with bots or scraping programs), or use it to build a competing service;
• get around usage limits or technical or security measures, or try to access other people's accounts or data;
• abuse the "Request a document" feature, for example with bulk requests or links that are not from official sources;
• enter, store or share unlawful content, or information you are not entitled to process or share;
• use Lex for purposes contrary to the intended purpose in section 2, in particular to examine or decide cases or to assess students;
• use Lex to harass, deceive or harm other people, or for unlawful activities;
• disrupt or overload the service.

5. Your content

What you write and keep in Lex (questions, topics, notes, annotations and, if the feature is available, documents you upload) remains yours. You give ALMA only the permission needed to provide the service: to store that content, process it to give you answers (including sending it to the artificial intelligence models listed in the Privacy Policy) and show it to you and to the people you share it with. This permission ends when you delete the content or your account, except for copies other people have already imported or can still import (section 8) and what you kept in spaces shared with other people. ALMA does not use your content to train artificial intelligence models or for advertising.

Only upload or share content you have the right to use. Documents you upload stay private in your account.

Copies. Lex is not an archive or a backup service. Keep copies of the content that matters to you: you can save your topics and annotations as a .lex file (section 11).

Unlawful content. If we receive a substantiated notice that content stored in Lex is unlawful, or we otherwise become aware of it, we may remove it or disable access to it. In that case we explain our decision and the reasons for it, unless the law prevents us, and you can contest it by replying to our email: a person reviews the decision. To report unlawful content, see section 19.

6. Other people's information and professional secrecy

Only enter information about other people that you are entitled to process, and only what your research needs. Describe the facts anonymously whenever you can.

If you are bound by professional secrecy (for example Article 92 of the Portuguese Bar Association Statute, the Estatuto da Ordem dos Advogados), it is for you to decide what information you enter in Lex; we recommend that you don't enter details that identify clients or other people. Professional secrecy binds you, not ALMA, which is not subject to it: complying with your duties of secrecy and data protection for what you enter in Lex, including about your clients, is your responsibility.

ALMA treats what you write in Lex as confidential: it uses it only to provide the service to you, does not use it to train models, does not sell it, shares it only with the processors listed in the Privacy Policy and with the people you choose to share it with, and only looks at it at your request, to keep the service secure or where the law requires it. On request, before you start using Lex, ALMA will sign a written confidentiality declaration. If an authority demands access to your content, we will tell you, where the law allows, so that you can invoke professional secrecy.

7. Artificial intelligence

• Lex's answers are generated by artificial intelligence, by models hosted on Cloudflare's network (the Workers AI service). Lex does not use other artificial intelligence providers, such as Claude, from Anthropic. If that changes, we will tell you first (section 10) and we will only send your questions to another provider with your permission.
• Each answer shows which model wrote it.
• Artificial intelligence systems can give wrong, incomplete or out-of-date answers, even when they sound confident. Before using any statement of fact or law from an answer, check it independently, in the cited sources and in the official sources.
• What is sent to the models and what happens to it is described in the Privacy Policy.

8. Sharing

You can send topics and annotations to other Lex users or save them as a file. The recipient can import a copy, which then belongs to them and does not disappear if you delete the original. Until it is imported or declined, you can take the share back. The share can be imported for 180 days after it was sent, unless it is declined or taken back sooner, even if you delete your account in the meantime. Before sharing, make sure you may share the information, especially data about clients or other people.

9. Price, paid plans and purchases

Free account. Creating a Lex account and downloading the app are free. An account without a paid plan gets 15 welcome credits, once, to ask questions, and can read the answers and the sources those answers cite. Search, the codes and their articles, case law, news, the library, annotations and sharing need a subscription. ALMA offers paid plans (subscriptions) and credit packs. Before you buy, the app shows what each includes and its price. If we change what is free, we tell you as set out in section 10.

Only on the App Store. Paid plans and credit packs are sold only on the App Store, in the Lex app for iPhone, iPad and Mac. We do not sell them on the web or in any other way. A subscription bought on the App Store also applies to the same Lex account at lex.alma.dev.

Apple is the seller. For App Store purchases, the seller is Apple: it takes the payment, handles VAT and issues the invoice. Apple's terms of sale apply, including its refund terms, and refunds are requested from Apple. ALMA receives only the purchase data it needs to give you access (Privacy Policy, section 12).

Credits and included usage. Credits from packs never expire. The usage included in a plan is counted per month: it starts again each month, and what you don't use in a month does not carry over to the next.

Managing and cancelling. An App Store subscription is managed and cancelled in your Apple account's settings. Deleting your Lex account does not cancel the subscription.

10. Availability and changes

Availability. We work to keep Lex available and its collection up to date, but there may be interruptions, for example for maintenance, technical faults or faults at the official sources. Where possible, we announce planned interruptions in advance.

Changes to the service. We may change Lex for these reasons: to comply with the law or decisions of authorities; for security reasons; because an official source has changed or is no longer available; to fix errors; or to improve the service and add features. If a change has a significant negative impact on how you use Lex, we tell you by email at least 30 days in advance, unless the law or the security of the service requires a shorter period.

Changes to these Terms. For the same reasons, or to reflect new features or plans, we may change these Terms. We tell you by email at least 30 days before the new version takes effect, unless the law requires a shorter period. If you don't agree, you can stop using Lex and delete your account, at no cost, before that date or within the following 30 days. Earlier versions remain available (section 18).

11. Suspension and termination

By you. You can stop using Lex and delete your account at any time, in Settings → Sign-in & security → Delete account. Before that, you can save your topics and annotations as a .lex file. If you have an App Store subscription, cancel it in your Apple account: deleting your Lex account does not cancel it (section 9). What happens to your data afterwards is explained in the Privacy Policy.

By ALMA. We may suspend or close an account in case of a serious or repeated breach of these Terms, unlawful content, a risk to the security of the service or of other people, or where the law requires it. Except in serious or urgent cases, we warn you first and give you the chance to respond. The decision is taken or reviewed by a person, we explain the reasons, and you can contest it by replying to our email.

If ALMA stops providing Lex, we tell you by email at least 30 days in advance, so that you can save your content.

12. Liability

ALMA is liable as provided by law, within the following limits, to the extent the law allows them.

What ALMA does not guarantee. Without prejudice to your rights under the law, ALMA does not guarantee that Lex will always be available or free of errors, that its answers are accurate, complete or up to date, or that Lex will meet your particular needs.

For all users. ALMA is not liable for damage caused:

• by using an answer, quote or document without the check against the official sources that section 2 requires, or by decisions, pleadings or advice based on it;
• by errors, omissions or delays of the official sources or other sources the collection comes from;
• by content you enter in breach of sections 4 to 6, or by your breach of these Terms or of the law;
• by someone else using your account with credentials you did not keep safe (section 3), before you tell us;
• by the loss of content that a copy of your own would have avoided (section 5);
• by events outside ALMA's reasonable control, such as failures of public networks, power or suppliers, attacks that could not reasonably have been prevented, natural disasters or acts of authorities.

If you use Lex in your professional or business activity, and not as a consumer:

• ALMA is not liable for loss of profit, clients, opportunities or reputation, for indirect damage, or for the procedural, disciplinary or contractual consequences of your work (for example costs, fines, sanctions or missed deadlines);
• ALMA's total liability for all damage relating to Lex is limited to the amount you paid for Lex (including on the App Store) in the 12 months before the event that caused the damage, or 100 euros if you paid nothing;
• you will compensate ALMA for the losses and reasonable costs, including legal fees, it incurs because of claims by third parties (for example your clients, a professional body or an authority) arising from your use in your work of Lex's answers without the check section 2 requires, or from information about clients or other people that you entered in Lex in breach of these Terms or of the law.

Nothing in these Terms excludes or limits ALMA's liability for harm to life, health or physical integrity, for damage caused intentionally or with gross negligence (by ALMA or by anyone acting on its behalf), or any other liability or consumer right that the law does not allow to be excluded or limited.

Lex's answers are general legal information, generated without knowing all the facts of a case, and should be checked against the official sources before they are used.

13. Intellectual property

Lex's software, its design, the brand and the selection, organisation and presentation of the collection belong to ALMA or its licensors. Official texts are reproduced from the public sources shown on each document, and ALMA claims no rights in them. References to and summaries of third-party works (for example academic works) remain subject to the rights of their owners. You may use what you find in Lex for your research, study and work, citing the source, within the limits of section 4.

14. Privacy

How we handle your personal data, including what is sent to the artificial intelligence models, is set out in the Lex Privacy Policy.

15. The App Store app

If you use the Lex app downloaded from the App Store, Apple's App Store terms also apply, and Apple's terms of sale apply to purchases made on the App Store (section 9). These Terms govern the Lex service; Apple is not a party to them.

16. Complaints and disputes

If you have a problem, write to us at support@alma.dev. We try to sort it out quickly.

Complaints book. You can file a complaint in the electronic complaints book (Livro de Reclamações Eletrónico) at www.livroreclamacoes.pt.

Alternative dispute resolution. In a consumer dispute, you can turn to a consumer alternative dispute resolution body, for example:

• Centro de Arbitragem de Conflitos de Consumo de Lisboa (CACCL), www.centroarbitragemlisboa.pt;
• Centro Nacional de Informação e Arbitragem de Conflitos de Consumo (CNIACC), www.cniacc.pt, with supplementary competence across Portugal.

The full list of bodies is on the Portal do Consumidor at www.consumidor.gov.pt. In consumer disputes worth up to 5,000 euros, if the consumer chooses to submit them to a legally authorised consumer arbitration centre, ALMA is bound by that arbitration (Article 14(2) of Portuguese Law 24/96 of 31 July). If you live in another European Union Member State, you can get help from the European Consumer Centre in your country.

17. Governing law and courts

Portuguese law applies, without prejudice to the mandatory consumer protection rules of the country where you habitually reside. Consumers may bring proceedings in the courts of their domicile or in the courts of Portugal, and may use the alternative dispute resolution bodies listed above.

18. Language and versions

These Terms exist in Portuguese and in English. The Portuguese version prevails; where the meaning of a clause is in doubt, the meaning more favourable to the user prevails.

This is version 1, dated 7 November 2026.

Versions: version 1, 7 November 2026 (current).

19. Points of contact and reporting unlawful content

Single point of contact for Member State authorities, the European Commission and the European Board for Digital Services (Article 11 of Regulation (EU) 2022/2065, the Digital Services Act) and for recipients of the service (Article 12): legal@alma.dev. Languages: Portuguese and English.

To report content you consider unlawful, write to legal@alma.dev with: an explanation of why you consider the content unlawful; exactly where it is (for example the link, or the name of the person who shared it with you and the topic's title); your name and email (optional for reports of child sexual abuse); and a statement that you believe in good faith that the information in your report is accurate and complete. We acknowledge receipt, examine the report diligently and tell you our decision and how you can contest it.
