Terms of use

Version 1 of 8 October 2026. These terms apply when you use Cabdell's services, and you accept them, with a click, before your first signature. Please read them; they are short for what they cover. Leer en español

1. Who we are

Cabdell's services are provided by:

  • Name: pending
  • Legal form: pending
  • Tax identification number (NIF): pending
  • Address: pending
  • E-mail: the contact address (pending)

Contact: the contact address (pending). More ways to reach us, and how to send notices and orders, are in the legal notice.

2. What Cabdell is

Cabdell is an open system for publishing science on the Algorand blockchain. Our services are this website, the Cabdell indexer and its API, our IPFS gateway and node, the documentation, browser notifications, the preparation of Zenodo drafts, and a private test sandbox for invited testers.

  • The Cabdell contract on Algorand is software that nobody can modify, ourselves included. It records publications, reviews, comments, votes, flags and reputation, and keeps the storage deposits. We do not run the blockchain.
  • We do not review, approve or endorse content. Everything is published by its authors. The figures we compute (reputation, Thread Score, the Peer-reviewed seal, citations) describe what the public record shows, by published rules; they are not our opinion of a work or a person.
  • Cabdell charges nothing. The network fees, storage deposits and bonds described below are paid to the Algorand network and to the contract, not to us.

3. Who may use it

You may read Cabdell without accepting anything. To sign anything you must be at least 16 years old and able to accept these terms. If you act for an institution, you confirm that you may bind it.

4. Your wallet

Cabdell is non-custodial: your wallet app holds your private key and signs each action; we never see your key or hold your funds, and we cannot sign, cancel or reverse anything for you. Keep your key safe: if you lose it, nobody can recover the address. Before you sign, the website shows the total cost; your wallet shows what you sign.

5. What you sign is public and permanent

Every action you sign is recorded on a public blockchain, with your address, permanently. It cannot be deleted or changed by anyone, including us; a later action can only add to it (a new version, an amendment, a retraction, an unfollow). Texts published on IPFS can be copied and kept by anyone. Publishing is your request that our services store, index and show your content. Read the privacy policy before you link your name to an address.

6. Costs, deposits and bonds

  • Network fees (about 0.001 ALGO per transaction) are paid to the Algorand network.
  • Storage deposits are non-refundable: the ALGO you pay when an action creates a record stays locked in the contract for as long as the record exists, which is for ever. Nobody receives them, ourselves included. The only exceptions are a flag's storage deposit, which comes back when the flag is settled, and the 0.1 ALGO that holding an article token keeps in your own account.
  • Overpayments are kept: anything paid to the contract above what it requires stays in the contract and is not returned. The website always pays the exact amount.
  • Bonds for flags. A flag deposits a bond (1 ALGO, more after the article was cleared in the past year, at most 16 ALGO). It comes back to you if the article is retracted or the round lapses. If governance clears the article, half goes to the article's submitter and the other half stays in the contract for good. If nobody decides within 60 days and the dispute expires, the whole bond stays in the contract for good: nobody can ever withdraw it.
  • Governance. One address, held by us, registers fields and carries out the outcome of disputes, within the rules of the contract. The times we give for it (for example, acting on a jury's outcome within seven days) are goals, not guarantees. If governance does not act, the contract's own rules apply, including the expiry above.
  • TestNet and the sandbox have no value. Their ALGO, reputation and records are for testing, can be reset, and carry nothing over to MainNet.

The About page lists every deposit and rule.

7. Your content and its licence

You keep the rights to what you publish. When you publish:

  • an article (or dataset, notes, amendment or replication), it is under the licence you choose when you publish it;
  • a review or a comment, it is under the Creative Commons Attribution 4.0 International licence (CC BY 4.0);
  • in every case you grant the operator a non-exclusive, worldwide, royalty-free licence, for the whole term of copyright, to reproduce, store, pin, index, analyse for search and for the figures above, quote in excerpts, convert to other formats, make available to the public and transmit your content through the website, the API, the gateway and IPFS, to keep it in backups, and to send it to Zenodo when you ask for a DOI. Because the record is permanent, this licence cannot be withdrawn for what is already published; it ends for what we stop showing.

You confirm that you have the rights needed to publish your content and to grant these licences, including for figures, data and text of others (quote only what the law allows, and cite it).

8. Acceptable use

Do not use Cabdell to publish or do anything illegal, and in particular do not:

  • publish content that infringes someone else's rights (copyright, image, honour, privacy, trade secrets);
  • publish other people's personal data without a lawful basis; health, genetic or other special-category data about research participants only when it is properly anonymised, with the ethics approval and consent your research requires;
  • publish spam, malware, phishing, scams or content meant to deceive, or impersonate someone;
  • harass or threaten people, or use flag notes, juror reasons, list or journal texts for personal attacks;
  • attack, overload or try to get around the limits and protections of our services;
  • hide that a text was generated by artificial intelligence where readers would expect to know (say so in the article).

9. Content moderation

No filter before publication. We do not check content before it is published. We stop showing something on our services only in four cases:

  1. an order from a court or a competent authority;
  2. a notice that shows clearly that something is illegal;
  3. content against these terms of a kind we can judge plainly: spam, malware, phishing;
  4. a data-protection request of a person about their own data, when the law gives them that right.

Disagreement with a work is never a reason: it is answered with reviews, comments and flags.

What it does. "Withholding" means that our website, API and gateway stop showing the item, our IPFS node deletes it and refuses to serve it, and the item's page says why, since when and how to contest it. It applies to this service only: the blockchain record does not change, and other services and people who keep copies may still show it. Terrorist content is first kept in a protected copy for six months, as the law requires; child sexual abuse material is removed without keeping any copy and reported to the police.

Notices. Anyone can send a notice through the notice form or to the contact address (pending). We confirm receipt, judge notices carefully, objectively and in proportion, and tell the notifier our decision.

Statements of reasons. When we withhold something you published, we tell you why, on the item's page and in your Cabdell inbox, with the ground, the facts, the scope and how to contest it.

Contesting. You can ask us to review any decision by writing to the contact address (pending); you can also go to the courts, and, once Spain empowers it, complain to the CNMC as Digital Services Coordinator. Every case is counted in the transparency report.

Scholarly integrity. Flags, disputes, juries and governance's decisions (clear or retract) are Cabdell's process for plagiarism, fabrication and similar problems. They follow the published rules of the contract and the indexer; flags are not legal notices. Automatic tools also shape what you see: the seal, reputation and Thread Score, the ranking of search results, a daily digest for notifications from new accounts, a 20 MB limit per publication, a pin quota of 200 MB per address every 30 days, rate limits, and hiding the notes of flag rounds that lapsed.

10. Services of others

Your wallet, your pinning service (Pinata, Filebase or your own node), Zenodo, ORCID and NFD are run by others under their own terms, which you accept with them. We are not responsible for them. If you publish through a pinning service, your account and key there are yours; we never store them on our servers.

11. Donations

Donations are voluntary gifts. They give no rights, services or influence, cannot be refunded once sent on the blockchain, and are not tax-deductible unless we tell you otherwise.

12. Availability and changes to the service

We run Cabdell with care but cannot promise that it is always available or free of errors, and we may change, suspend or end services. The record on the blockchain stays available whatever happens to our services, and anyone can run another indexer or website.

13. Liability

We are liable under the law for damage we cause intentionally or through gross negligence, and for anything else the law does not let us exclude. Otherwise, as Cabdell is provided free of charge, we are not liable for losses caused by the blockchain, wallets or services of others, by what other people publish, by your own errors in signing, or by the loss of your key. Nothing in these terms limits the rights you have as a consumer.

14. Changes to these terms

We will publish any new version on this page with its number and date. When a change is significant, we announce it on the site before it applies, and we ask you to accept the new version before your next signature. If you do not accept it, you can still read Cabdell.

15. Law and courts

These terms are governed by Spanish law. If you are a consumer, you keep the protection of the mandatory rules of the country where you live (Rome I Regulation, art. 6), and you may bring proceedings in the courts of your country, the only courts where you can be sued (Brussels I bis Regulation, arts. 17-19). Otherwise, the courts of the operator's domicile have jurisdiction.
