Terms of Service
Version 2.0 · Last updated: 26 August 2026 · Supersedes the version of 22 August 2026
1. Who we are
This service is operated by Decibest Financial, Spain. You can contact us at support@decibest.com. Our website is https://decibest.com.
In these terms, "Decibest", "we", "us" and "our" mean that entity. "You" means the person using the service.
We are not authorised or registered by the Comisión Nacional del Mercado de Valores (CNMV) or by any other financial supervisory authority, and we do not provide any regulated investment service. See clause 5.
2. What these terms cover
These terms form a binding contract between you and us and govern your access to and use of decibest.com, our web application and any related services (together, the "Service"). Our Privacy Policy at https://decibest.com/privacy forms part of this contract.
By creating an account or otherwise using the Service you accept these terms. If you do not accept them, do not use the Service.
3. The Service
The Service is a stock research terminal. It applies a documented, deterministic rule-based model to price data and company fundamental data supplied by third parties, and returns:
- a numerical score from 0 to 100 and a verdict label (GO, CAUTION, WAIT or STAND ASIDE);
- a breakdown of that score across five weighted pillars, with every scored rule shown individually;
- an Investment Matrix, an entry-quality assessment and a stability grade;
- a written explanation of the above, generated by an AI system (see clause 13);
- tools for you to record watchlists, holdings, alert rules and your own decisions.
The specific features available to you depend on the plan you subscribe to, as described on our pricing page at the time you subscribe. We may add, change or withdraw features. Where a change materially and negatively affects a feature you are paying for, clause 17 applies.
4. Nature of the outputs
4.1 These are general investment recommendations. The scores, verdicts and pillar breakdowns produced by the Service constitute investment recommendations within the meaning of Article 3(1)(35) of Regulation (EU) No 596/2014 (Market Abuse Regulation), produced and disseminated in accordance with Commission Delegated Regulation (EU) 2016/958.
4.2 They are not personal recommendations. Outputs are produced by a deterministic algorithm and are issued in identical form to every user who requests analysis of the same instrument on the same date. They take no account of your financial situation, investment objectives, investment horizon, knowledge, experience, tax position or risk tolerance. They are not a personal recommendation within the meaning of Article 9 of Commission Delegated Regulation (EU) 2017/565, and nothing in the Service constitutes investment advice, portfolio management, order reception or transmission, or any other investment service or activity under Directive 2014/65/EU (MiFID II).
4.3 Nothing here is advice. Nothing in the Service is investment, financial, tax, accounting or legal advice, or an offer, solicitation or recommendation to buy, sell or hold any security. Markets involve risk. You may lose some or all of the money you invest. Past performance does not predict future performance. Every investment decision you take is yours alone and taken at your own risk.
4.4 Where the disclosures live. The disclosures required by Delegated Regulation (EU) 2016/958 — including our identity, our methodology and the basis of the valuation, the meaning of each verdict category, our data sources, the frequency with which recommendations are updated, and the proportion of recommendations falling into each verdict category over the preceding twelve months — are published and kept current on our methodology page. That page forms part of these terms.
4.5 Model validation status. Individual components of the model may not have been independently validated against forward returns. Where that is the case, we say so in the product and on the methodology page, and you must treat the component accordingly. A verdict is a structured summary of rule outcomes on historical and current data. It is not a forecast of price and we make no claim that it predicts returns.
4.6 Conflicts of interest. Decibest, its officers and its staff hold no position in the instruments covered by the Service, receive no compensation from issuers, and have no other interest capable of impairing the objectivity of the outputs. If that changes, we will disclose it here and on the methodology page.
5. Our regulatory status
We are not an empresa de servicios de inversión, an empresa de asesoramiento financiero (EAF), a credit institution or a collective investment scheme manager. We are not supervised by the CNMV. We do not hold client money or client assets, we do not execute or transmit orders, and we do not manage portfolios.
If you want a personal recommendation that takes your own circumstances into account, consult a firm authorised to provide investment advice in your jurisdiction. You can check authorisation in Spain in the CNMV's public registers at www.cnmv.es.
6. Eligibility and accounts
6.1 You must be at least 18 years old and have capacity to enter into a contract. 6.2 You must give accurate registration information and keep it up to date. 6.3 You are responsible for keeping your credentials secure and for all activity under your account; tell us promptly at support@decibest.com if you believe your account has been compromised. 6.4 Accounts are personal: you may not share, sell or transfer your account or its credentials, and you may not let others use it.
7. Subscriptions, billing and renewal
7.1 Plans and prices. Paid plans and their prices are shown at checkout before you commit. Prices for consumers are shown inclusive of applicable VAT, charged at the rate applicable in your country of residence. Business customers with a valid EU VAT number outside Spain may be invoiced under the reverse-charge mechanism.
7.2 The order is binding. You confirm your order using a button explicitly labelled to indicate that the order carries an obligation to pay. We send you confirmation of the contract, including these terms, by email on a durable medium.
7.3 Automatic renewal. Paid plans renew automatically for successive periods of the same length at the price then in force, until cancelled. We tell you at checkout what the period is and what the renewal price will be.
7.4 Free trials. Where a free trial is offered, we tell you before you start it how long it lasts, what it converts into, and what you will be charged. Unless you cancel before the trial ends, the trial converts to a paid subscription and the first charge is taken on the day it ends. We send you a reminder by email at least 7 days before that happens.
7.5 Cancellation. You can cancel at any time from the billing portal, with effect from the end of the period you have already paid for. Cancellation stops future renewals; it is not a request for a refund of the current period (see clause 8). On cancellation you keep full access until the end of the paid period, after which your account moves to the free plan.
7.6 Failed payments. If a payment fails we may retry it and may suspend paid features until payment succeeds. We will tell you before suspending.
7.7 Price changes. We may change our prices and will tell you by email at least 30 days before a change takes effect. A price change never applies to a period you have already paid for; it applies from your next renewal. If you do not accept the new price, cancel before that renewal and no further charge will be taken.
8. Right of withdrawal (EU consumers)
8.1 The right. If you are a consumer resident in the EU, you have 14 days from the day the contract is concluded to withdraw from it without giving any reason and without penalty.
8.2 How to withdraw. Tell us by an unambiguous statement before the 14 days expire — email support@decibest.com, or use the model withdrawal form in Annex A. You do not have to use the form.
8.3 Immediate performance. At checkout you may expressly request that we begin providing the Service before the 14-day period expires, and acknowledge that you will lose the right of withdrawal once the Service has been fully performed for the period concerned. We confirm both to you by email. If you do not make that request, we begin providing the Service when the 14 days end.
8.4 If you withdraw after performance has begun. You owe us an amount proportionate to what has been supplied up to the moment you told us you were withdrawing, calculated against the total contract price for that period. We refund everything else within 14 days of being told, using the same payment method you used, at no cost to you.
8.5 When the right is lost. You lose the right of withdrawal only once the Service has been fully performed for the period concerned, and only where you made the express request and acknowledgement in clause 8.3 and we sent you the confirmation. Beginning to use the Service does not by itself extinguish the right.
8.6 Refunds outside the withdrawal period. Outside clause 8.1 we do not generally refund periods already begun, but this does not affect your statutory rights on lack of conformity under clause 14 or any refund we choose to grant.
9. Acceptable use
You may not:
- scrape, crawl, bulk-download, resell, redistribute, sublicense or publicly display data or outputs from the Service, except for your own personal or internal business use;
- circumvent or attempt to circumvent access controls, quotas, rate limits or paywalls;
- reverse-engineer the model, or use outputs to build or train a competing product or a machine-learning model;
- share account credentials, or provide access to the Service to anyone who is not an authorised user of your account;
- use the Service to break the law, including market abuse, insider dealing or market manipulation under Regulation (EU) No 596/2014;
- interfere with, overload or attempt to disrupt the Service or its infrastructure.
Automated or programmatic access is only permitted under a written API agreement with us.
10. Intellectual property
10.1 Ours. The Service, the model, the scoring methodology, the software, the interface, the documentation and all associated trade marks are owned by us or our licensors and are protected by intellectual property law. Nothing in these terms transfers any of it to you.
10.2 Your licence. While your account is in good standing we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service, and to use its outputs, for your own personal or internal business investment research. Clause 9 limits that licence.
10.3 Yours. You keep all rights in the content you put into the Service — watchlists, holdings, notes, decisions and preferences. You grant us only the licence we need to host, process and display it back to you in order to operate the Service.
10.4 Feedback. If you send us suggestions, we may use them without obligation or compensation to you.
11. Third-party data
Prices, fundamentals, corporate data and news are supplied by third parties. That data may be delayed, incomplete, revised, restated or wrong, and may be unavailable. We do not control it, do not independently verify it, and do not warrant its accuracy, completeness, timeliness or availability. Model outputs are only as good as the data they are computed from, and an output computed from bad data will be wrong without necessarily being flagged as wrong. Our current data sources are listed on the methodology page.
12. Availability
We aim to keep the Service available but do not guarantee uninterrupted or error-free operation. We may carry out maintenance, and will give notice of planned maintenance where reasonably practicable. Third-party outages, including at our data providers, may make parts of the Service unavailable.
13. Artificial intelligence
Some written explanations, summaries and commentary in the Service are generated by an AI system. You are interacting with an AI system when you read them. This is disclosed in accordance with Article 50 of Regulation (EU) 2024/1689 (the AI Act).
The verdict, the score, the pillar breakdown, the stability grade and every scored rule are produced by a deterministic algorithm, not by the AI system. The AI system only describes outputs that already exist; it does not produce, alter, weight or override them. AI-generated text may nonetheless contain errors or mischaracterise the underlying output. Where the AI text and the structured output disagree, the structured output governs.
14. Conformity, warranties and liability
14.1 We will provide the Service with reasonable skill and care and in conformity with these terms and with the description of the Service published on our site.
14.2 If you are a consumer, you have statutory rights on lack of conformity of digital services under Directive (EU) 2019/770 as transposed in Spain (Real Decreto Legislativo 1/2007, Arts. 115 bis et seq.) and under equivalent law in your country of residence. Nothing in these terms excludes, limits or makes conditional those rights.
14.3 Subject to clauses 14.1 and 14.2, we do not warrant that the Service will be uninterrupted or error-free, that any output will be accurate, complete or suitable for you, or that any output will be profitable or will predict any future price or return.
14.4 Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, or for anything else that cannot be excluded or limited by law.
14.5 Subject to clause 14.4, we are not liable for losses arising from investment decisions you take, whether or not those decisions were informed by the Service. Clause 4 governs the nature of the outputs.
14.6 Subject to clauses 14.2 and 14.4, and to the extent permitted by law: we are not liable for indirect or consequential loss, loss of profit, loss of opportunity or loss of anticipated savings; and where you use the Service for purposes relating to your trade, business, craft or profession, our aggregate liability arising out of or in connection with these terms is limited to the total amount you paid us in the twelve months before the event giving rise to the claim. That limitation does not apply to consumers.
15. Personal data
We process personal data as described in our Privacy Policy, in accordance with Regulation (EU) 2016/679 (GDPR) and Spanish Organic Law 3/2018 (LOPDGDD).
16. Suspension, termination and what happens to your data
16.1 By you. You can close your account at any time from account settings. Clauses 7.5 and 8 govern the financial consequences.
16.2 By us. We may suspend or terminate your account if you materially breach these terms, if we are required to do so by law, or if your use presents a security or legal risk. Except where the breach is serious or where the law requires immediate action, we will tell you what the problem is and give you a reasonable opportunity to fix it before we act. Where we suspend or terminate an account on the basis of an automated check, you may request human review by emailing support@decibest.com.
16.3 Effect on paid periods. If we terminate your account other than for your material breach, we refund the unused part of any period you have paid for.
16.4 Your data. On closure or termination, your personal data is erased or anonymised in accordance with the retention schedule in the Privacy Policy. Export your data before closing your account if you want to keep it; we cannot restore it afterwards.
17. Changes to these terms
We may change these terms. We will publish the new version with an updated date and, for changes that materially affect your rights or obligations, notify you by email or in the app at least 30 days before they take effect.
For paid subscriptions, material changes take effect at your next renewal. If you do not accept them, cancel before that renewal; the change will not be applied to you and no further charge will be taken. Continued use after a material change takes effect means you accept it.
18. Complaints and out-of-court dispute resolution
18.1 Contact support@decibest.com first. We will acknowledge your complaint within 5 working days and give a substantive reply within 14 days.
18.2 We are not currently adhered to any alternative dispute resolution entity and are not obliged to participate in ADR proceedings. You may nonetheless approach a competent national ADR entity; the list maintained by the European Commission is at https://consumer-redress.ec.europa.eu/dispute-resolution-bodies.
18.3 Consumers resident in Spain may also use the Sistema Arbitral de Consumo and may contact the consumer authorities of their autonomous community. Consumers resident elsewhere in the EU may contact the European Consumer Centre in their country.
19. Governing law and jurisdiction
19.1 These terms are governed by Spanish law.
19.2 If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of your country of habitual residence (Article 6 of Regulation (EC) No 593/2008, Rome I). You may bring proceedings in the courts of your country of residence, and we may only bring proceedings against you there.
19.3 If you are not a consumer, the courts of Spain have exclusive jurisdiction.
20. General
20.1 Severability. If a provision is held invalid or unenforceable, the rest remains in force and the invalid provision is replaced by a valid one that comes closest to its purpose.
20.2 No waiver. If we do not enforce a right, we do not waive it.
20.3 Assignment. You may not assign these terms. We may assign them to a successor in connection with a merger, acquisition or sale of assets, on notice to you and provided your rights are not reduced. If you are a consumer, you may terminate without penalty if you object to the assignment.
20.4 Force majeure. Neither party is liable for failure to perform caused by events beyond its reasonable control. This does not affect your right to a refund for a service not supplied.
20.5 Notices. We contact you at the email address on your account; keep it current. You contact us at support@decibest.com.
20.6 Entire agreement. These terms, the Privacy Policy and the methodology page are the entire agreement between us on their subject matter, and replace any prior version. This does not exclude liability for fraudulent misrepresentation.
20.7 Language. These terms are published in English, and the English version prevails, save that consumers may rely on the version in the language in which the contract was concluded.
