**Disclaimer:** This document is a practical operating draft for product launch and hosting compliance. It is **not** a substitute for advice from a qualified lawyer in your jurisdiction. Have it reviewed before relying on it for regulated activity or large-scale EU processing.

1. Acceptance

By creating an account, accessing, or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

If you use the Service on behalf of an organisation, you represent that you have authority to bind that organisation.


2. The Service

OpenReef provides a web platform to:

The Service is provided on a commercial / beta basis as described on the website. Features may change.


3. Accounts

You must provide accurate registration information and keep credentials confidential. You are responsible for activity under your account.

We may suspend or terminate accounts that violate these Terms, applicable law, or that pose security or abuse risk.


4. Credits, payments, and refunds


5. Datasets and user content (critical)

5.1 Your responsibility

You retain ownership of datasets and materials you upload (“User Content”). You grant us a limited licence to host, process, transmit, and display User Content solely to provide the Service (including to subprocessors and compute providers as needed to run jobs you launch).

You represent and warrant that:

1. You have all rights, licences, and lawful bases to upload and process the User Content for fine-tuning.

2. User Content does not unlawfully infringe third-party IP, privacy, or other rights.

3. You will not upload content that is illegal under applicable law.

5.2 Prohibited data (personal & special categories)

You must not upload datasets that contain:

ProhibitedExamples (non-exhaustive)
Special categories of personal data under GDPR Art. 9Health, biometric identifiers for identification, genetic data, racial/ethnic origin, political opinions, religious/philosophical beliefs, trade-union membership, sex life or sexual orientation
Criminal-related personal data (Art. 10 GDPR and equivalents)Convictions, offences, investigations
Personal data of third parties without a valid legal basis and required notices/consentsCustomer lists, employee records, scraped private profiles, phone books of individuals
Children’s data where restricted by lawData of minors under applicable age thresholds
Secrets / credentialsAPI keys, passwords, private keys, full payment card numbers, government ID numbers used as identity documents
Malware or abusive contentExploit code intended for harm, CSAM, terrorist content, etc.

Allowed by default (examples): synthetic instruction/output pairs; public-domain or licensed text you have rights to use; your own non-sensitive content; open datasets that are already lawfully redistributable and do not include prohibited categories above.

If your use case requires processing personal data of third parties or special-category data, do not use OpenReef unless you have a written enterprise agreement with us that expressly covers that processing. The self-serve Service is not designed or offered for that purpose.

5.3 Our role regarding datasets

5.4 Hugging Face and third-party models

Using gated or third-party models requires compliance with Hugging Face and model licence terms. If you store an HF token, you do so under your own Hub account; you must not share tokens that grant broader rights than needed. We do not guarantee availability of any third-party model.


6. Decentralised compute (OpenGPU Network) — sub-processors

When you run a job in real / network mode (OpenGPU Network):

1. Your job configuration, dataset (or access to it), and related job metadata may be processed on third-party provider hardware operated by independent node operators (“Providers”).

2. Providers act as sub-processors (or independent processors under network rules) for the compute step. They are not our employees.

3. Providers may be located inside or outside the European Economic Area. By launching a network job you instruct us to transfer necessary data to Providers for that job, including potential international transfers. We will use appropriate safeguards where required (e.g. SCCs / network contractual terms) as described in the Privacy Policy; you acknowledge that exact physical location of a given Provider node may not be fully transparent before routing.

4. Local mode keeps training on infrastructure you control (e.g. your machine or a VPS you operate); network mode does not.

5. We are not liable for Provider downtime, hardware failure, or Provider misconduct beyond remedies available under OpenGPU / our settlement rules (credits refunds where applicable).

If you cannot accept sub-processing on third-party GPUs or possible non-EEA locations, use only local mode or do not use the Service for that data.


7. Acceptable use

You will not:


8. Intellectual property


9. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant uninterrupted or error-free operation, or that training will achieve any accuracy target.


10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY ARISING OUT OF THE SERVICE IS LIMITED TO THE GREATER OF (A) AMOUNTS YOU PAID US FOR CREDITS IN THE 3 MONTHS BEFORE THE CLAIM, OR (B) EUR 50. WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR LOST-PROFITS DAMAGES.

Nothing excludes liability that cannot be excluded under mandatory law (e.g. intent, gross negligence, death/personal injury where applicable).


11. Indemnity

You will defend and indemnify us against claims arising from: (i) User Content; (ii) your breach of these Terms or law; (iii) your use of models/outputs in violation of third-party licences—except to the extent caused by our wilful misconduct.


12. Suspension and termination

We may suspend or terminate access for breach, risk, non-payment, or legal requirement. You may stop using the Service at any time. Provisions that by nature should survive (IP, liability, indemnity, dataset warranties) survive termination.


13. Changes

We may update these Terms by posting a new version with an updated date. Material changes may be notified in-product or by email where appropriate. Continued use after the effective date constitutes acceptance.


14. Governing law

Unless mandatory consumer law provides otherwise, these Terms are governed by the laws of Spain, and courts of [city to confirm, e.g. Madrid / Barcelona] shall have jurisdiction, without prejudice to mandatory rights in your country of residence.
