Terms of service

These terms govern your use of the KemJet workspace and website (the “Service”). By creating an account, or by using the Service, you agree to them. If you are agreeing on behalf of an organisation, you confirm you are authorised to bind it, and “you” means that organisation.

The Service is provided by KemJet. If we have signed a separate written agreement with you, that agreement governs where it conflicts with these terms.

A workspace for computational medicinal chemistry: drawing and storing structures, running trained property models against them, docking them into prepared receptors, searching for synthetic routes, generating analogues, and asking Palba about any of it.

The Service is under active development. Features change, and some of what is described on our marketing pages is better than others. Clause 6 sets out what the outputs mean.

• You must give accurate registration details and keep them current.
• You are responsible for your credentials and for what is done through your account. Tell us at security@kemjet.org if you believe it has been used without your authority.
• You must be at least 16, and using the Service for professional, academic or research purposes.
• One account is one person. Do not share credentials; invite colleagues to the workspace instead.

Data belongs to a workspace, not to an individual. A workspace owner administers membership and roles, can see the audit trail of what members did, can set retention, and can remove members and their access.

Where a workspace is created by an organisation, that organisation controls it. If you join a workspace your employer owns, they decide what happens to the work you do in it, including after you leave. That is a matter between you and them.

You own everything you put into a workspace and everything the Service produces from it: structures, results, routes, notes. We claim no ownership and acquire no rights in your chemistry.

You grant us a limited licence to host, copy, transmit and display that content strictly to operate the Service for you, to keep backups, and to fix faults. That licence exists so we can run the product and ends when the content is deleted.

We do not train models on your content. Our models are trained on public datasets. Yours is not among them, and it will not be without your written agreement.

You are responsible for having the right to put content into the Service, and for not uploading anything whose disclosure to us would breach an obligation you owe somebody else.

The Service is built to make its own limits visible, and you agree to heed them:

• Predictions carry calibrated intervals and applicability-domain flags. A compound outside the domain gets a number that is not supported by the training data, and the interface says so.
• Model quality varies by endpoint and is published per endpoint. Some are strong. Some are directional at best. Both are shown alongside the number.
• A docking score ranks poses within one receptor under one scoring function. It is not a binding affinity, and it is not comparable across targets.
• A proposed synthetic route is a search result over reaction templates. It has not been performed, and reagent availability, selectivity and safety are not established by its appearing.
• Palba can be wrong. It is a language model with tools, and the guards that catch its known failure modes do not catch everything.

You are the scientist. Independent verification and professional judgement remain yours, and nothing in the Service transfers them to us.

The Service is not a medical device, not a clinical decision support system, and not validated for any regulatory submission. It has not been cleared or approved by the MHRA, the FDA, the EMA or any other authority.

Do not use it to diagnose, treat, prevent or mitigate disease in any person; to make decisions about the care of an identifiable patient; or as the evidential basis of a regulatory filing. It is not validated to GxP standards and we make no claim that it is.

You will not:

• Use the Service to design, develop or produce chemical, biological or toxic weapons, controlled substances for unlawful supply, or anything else whose purpose is to cause harm.
• Breach any export control, sanctions or controlled-substance law.
• Attempt to access another customer’s workspace or data, or to defeat any access control.
• Probe, scan or load-test the Service without our written permission. Good-faith security research within your own account is welcome under the terms on the security page.
• Scrape the Service, resell access, or use it to build a competing product.
• Upload malware, or content that is unlawful or that infringes somebody else’s rights.
• Use automated means to consume compute beyond what a person using the interface would.

Each workspace has a compute budget. Runs that would exceed the remaining budget are refused before dispatch. We may apply rate limits, queue work, or decline a run that would degrade the Service for other customers.

While the Service is free, budgets are set at our discretion and can change. We will give notice before reducing one that you are relying on.

Palba is powered by a third-party language model. Using Palba sends your conversation, and whatever it refers to, to that provider. Their handling of it is governed by their terms, not ours.

The provider is named, with what it receives and where it operates, in the sub-processor table in our privacy policy. If you are not comfortable with that, the rest of the Service works without Palba.

The Service, its interface, its trained model weights, its documentation and the KemJet name and mark are ours or our licensors’. These terms grant you a non-exclusive, non-transferable right to use the Service, and nothing else.

You may not copy, decompile or reverse engineer the Service, or extract the model weights, except to the extent that restriction is unenforceable by law.

The Service incorporates third-party open-source components under their own licences, which continue to govern those components.

If you send us suggestions, we may use them without obligation, payment or attribution. This does not give us any right to your chemistry, which clause 5 governs.

We treat your workspace content as confidential and will not disclose it except to the sub-processors listed in the privacy policy, to the extent needed to run the Service, or where the law compels us. Where we are compelled and permitted to tell you, we will.

Our staff do not browse customer chemistry. Access to production data is limited to the people who need it to operate the Service, and is used to fix faults and to answer support requests you have raised.

We aim to keep the Service running and we do not promise that it always will be. There is no service level agreement at this stage, and we would rather say that than imply one.

We may change, suspend or withdraw features. Where a change removes something you depend on, we will give reasonable notice and a way to export your work.

We may suspend an account or a workspace immediately where there is a credible risk of harm to people, to other customers, or to the Service, or where clause 8 has been breached. We will tell you why, and restore access once the cause is resolved.

You may close your account at any time. We may end this agreement on 30 days’ notice, or immediately for a material breach that is not cured within 14 days of us telling you about it.

On termination we give you 30 days to export your content before deleting it. Clauses 5, 11, 12, 13, 18, 19, 20 and 23 survive.

The Service is provided “as is”. To the extent the law allows, we exclude all implied warranties, including merchantability, fitness for a particular purpose, accuracy and non-infringement.

We do not warrant that the Service will be uninterrupted or error-free, that its predictions will be accurate, or that a compound it proposes can be made, will bind, or will be safe.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited. The rest of this clause is subject to that.

We are not liable for loss of profit, revenue, business, anticipated savings, goodwill or opportunity; for loss or corruption of data beyond restoring the most recent backup; or for any indirect or consequential loss, in each case however arising.

We are not liable for any decision you take on the basis of the Service’s output, including the selection, synthesis, testing or advancement of a compound. Clause 6 sets out what that output is, and you accept the Service on that footing.

Our total aggregate liability arising out of this agreement is limited to the greater of the amounts you paid us in the 12 months before the claim, and £100.

You will indemnify us against claims arising from your content, from your use of the Service in breach of clause 8, or from your infringement of a third party’s rights. We will tell you promptly of any such claim and will not settle it without your agreement.

We may change these terms. For a material change we will give account holders at least 30 days’ notice by email and update the effective date above. Continuing to use the Service after that means you accept the change; if you do not, close your account and export your work within the notice period.

• You may not assign this agreement without our consent. We may assign it to a successor to our business.
• If any clause is unenforceable, the rest stands and the clause is narrowed to what is enforceable.
• A delay in enforcing a right is not a waiver of it.
• Nobody other than you and us has any right to enforce these terms.
• Notices to you go to your account email. Notices to us go to thekemjet@kemjet.org.
• These terms, together with the privacy policy, are the entire agreement between us on this subject.

This agreement is governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute arising from it.
