Terms of Service

1. What Thalias does

Thalias turns a decision and its supporting material into a structured map: alternative paths, the evidence and assumptions each rests on, and the outcome each leads to. When a source changes, it identifies the parts of that map which depend on the change and re-derives them.

Thalias produces analysis, not advice. It is not legal, financial, medical, tax, investment, safety, or professional advice of any kind. Every decision you make remains yours, and you are responsible for verifying anything you rely on.

2. Accounts

Some parts of the Service require an account. You are responsible for the accuracy of your registration details, for keeping your credentials secure, and for everything done under your account. Tell us promptly at [security@thalias.co] if you believe your account has been compromised.

You must be at least 18 and not barred from using the Service under applicable law.

3. Your content

“Your Content” means the documents, data, notes, messages, and other material you or your users submit to the Service, along with the maps and decision records generated from it.

You keep all rights in Your Content. You grant us a limited, non-exclusive licence to host, copy, process, transmit, and display it solely to operate and support the Service for you, and to comply with law. That licence ends when you delete the content or close your account, except for copies retained in routine backups for the period described in our Privacy Policy.

You confirm that you have the rights necessary to submit Your Content and that doing so does not breach any confidentiality obligation, licence, or law that applies to you.

4. Acceptable use

You agree not to:

• upload material you are not permitted to disclose, or that infringes another party’s rights;
• use the Service to build a competing product, or to benchmark it for publication without our written consent;
• reverse engineer, scrape, or attempt to extract the underlying models, prompts, or schemas;
• probe, overload, or interfere with the Service, or circumvent any limit or access control;
• use the Service to make decisions about a person’s legal rights, credit, employment, housing, insurance, or health without independent human review; or
• use the Service unlawfully, or to produce unlawful content.

5. AI output, and the limits of relying on it

Parts of the Service use large language models. Model output can be wrong, incomplete, or confidently mistaken. Thalias labels which nodes are traceable to a source and which are derived or assumed, and shows you a change before it is applied — but those signals are aids to your judgement, not a guarantee of correctness.

You must not rely on the Service as the sole basis for a consequential decision. Verify material facts against their sources before acting.

Output is not unique to you. Others may receive similar output from similar inputs, and we make no claim that output is original or non-infringing.

6. Model providers and your own keys

Where you supply your own API keys, your prompts and content are sent to the provider you have chosen and are governed by that provider’s terms as well as these. You are responsible for your relationship with that provider, for their charges, and for the configuration of your account with them.

Where we supply inference, we will tell you which providers process your content. We do not sell Your Content, and we do not use it to train our own or third-party models except where you explicitly ask us to.

7. Fees

Paid plans are billed as described at the point of purchase. Fees are exclusive of tax unless stated. Unless required by law, payments are non-refundable. We may change pricing on [notice period] notice, effective at your next renewal.

8. Our intellectual property

The Service, including its software, schemas, interfaces, and brand, belongs to us and our licensors. These terms grant you a limited, revocable, non-transferable right to use the Service, and nothing more. Feedback you send us may be used without obligation to you.

9. Confidentiality

Each party may receive non-public information from the other. The receiving party will use it only to perform under these terms, protect it with at least reasonable care, and not disclose it except to people who need it and are bound by similar obligations. This does not apply to information that is public through no fault of the receiver, independently developed, or lawfully obtained elsewhere.

10. Availability and changes

We may change, suspend, or discontinue parts of the Service. Where a change materially reduces functionality you rely on, we will give reasonable notice. Beta or preview features are provided as-is and may be withdrawn at any time.

11. Disclaimers

Except where prohibited by law, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted operation.

12. Limitation of liability

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, goodwill, or data, however caused.

Our total aggregate liability arising out of or relating to the Service is limited to the greater of [amount] or the fees you paid us in the [12] months before the event giving rise to the claim.

Nothing here limits liability that cannot lawfully be limited, including for death or personal injury caused by negligence, or for fraud.

13. Indemnity

You will defend and indemnify us against claims arising from Your Content, your use of the Service in breach of these terms, or your violation of law or of a third party’s rights.

14. Termination

You may stop using the Service at any time. We may suspend or terminate access if you materially breach these terms, or if required by law. On termination you may export Your Content for [30] days, after which we may delete it. Clauses that by their nature should survive termination will do so.

15. Changes to these terms

We may update these terms. If a change is material we will give notice before it takes effect — by email or in the product. Continuing to use the Service after that date means you accept the updated terms.

16. Governing law and disputes

These terms are governed by the laws of [jurisdiction], without regard to conflict-of-laws rules. The courts of [venue] have exclusive jurisdiction, except that either party may seek injunctive relief anywhere to protect its intellectual property or confidential information.

17. General

These terms, plus any order form, are the entire agreement between us. If a provision is unenforceable, the rest stands. Failure to enforce a right is not a waiver of it. You may not assign these terms without our consent; we may assign them in connection with a merger or sale of assets.
