Terms of Service

These Terms of Service (the "Terms") govern your access to and use of the Tarka platform, including its web application, APIs, analysis pipelines, and related services (together, the "Service"). By creating an account or using the Service you agree to these Terms. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization, and "you" refers to both you and the organization.

In short: the platform is ours, and your data and your results are yours. We provide and operate the Service; you keep ownership of everything you upload and everything the Service produces from it. The sections below spell that out.

1. Accounts

You must provide accurate information when creating an account and keep it up to date. You are responsible for safeguarding your credentials and for all activity under your account, including activity by anyone you allow to use it. Notify us promptly at the contact address below if you believe your account has been compromised.

Your organization may administer your account through its workspace, including enforcing security policies (such as two-factor authentication), assigning roles, and removing access.

2. Acceptable use

You may use the Service only for lawful research, analytical, and operational purposes. You agree not to:

• upload or process data you do not have the right to use, or that identifies individuals without a lawful basis and any required consents or approvals (such as IRB or ethics-board approval);
• attempt to re-identify individuals from de-identified or pseudonymized data;
• probe, scan, or test the vulnerability of the Service, or circumvent any access or rate controls, except as part of an authorized security engagement;
• interfere with the Service or other users, including by submitting workloads designed to degrade availability;
• resell, sublicense, or provide the Service to third parties except as permitted by your plan;
• use the Service to develop a competing product, or reverse-engineer any part of it not provided as open source.

We may suspend or limit access that we reasonably believe violates these Terms or creates risk for the Service or other users. Where practical we will notify you first.

3. Your data and your results

Everything you bring to the Service, and everything the Service produces for you, is yours. This includes the datasets, metadata, documents, and other content you upload or generate ("Customer Data"), and the pipeline outputs, trained models, feature selections, plots, reports, and other results derived from Customer Data ("Results"). As between you and us, you own all rights in Customer Data and Results, and we claim none.

You grant us a limited, non-exclusive license to host, process, transmit, and display Customer Data and Results solely to provide, secure, and support the Service for you, and as otherwise instructed by you or your organization. That license ends when the data is deleted from the Service, except for backups that expire in the ordinary course.

We do not use Customer Data or Results to train models made available to other customers, and we do not share them with anyone outside your organization except as required to operate the Service (for example, our hosting providers) or by law.

You are responsible for the lawfulness of Customer Data, including compliance with applicable data-protection, health-information, and research regulations. If Customer Data includes protected health information or similar regulated data, you must first have an appropriate written agreement with us that covers it. You can export Customer Data and Results at any time while your account is active.

4. Analysis results are aids, not advice

Results are computational aids. They are not medical advice, clinical decisions, or a substitute for expert judgment and appropriate validation. You are responsible for verifying Results before relying on them in research, clinical, or commercial contexts.

5. Plans, fees, and usage limits

Access to features and usage quotas depends on the plan assigned to your organization. Fees, billing periods, and renewal terms are set out in your order or plan description. Unless stated otherwise, fees are non-refundable. We may change plan pricing on renewal with reasonable prior notice.

We may enforce usage limits (such as pipeline runs, storage, or concurrent sessions) according to your plan and your organization's policies.

6. The platform is ours

The Service itself — its software, pipelines, algorithms, models we develop and ship as part of the Service, documentation, and design — is owned by us or our licensors and protected by intellectual-property laws. Your rights are limited to using the Service under these Terms; no ownership in the Service is transferred to you. Nothing in this section gives us any rights in your Customer Data or Results, which remain yours as set out in Section 3.

If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them without obligation to you.

7. Third-party services

The Service may integrate with third-party services (for example, identity providers, cloud storage, or external data repositories). Your use of those services is governed by their own terms, and we are not responsible for them.

8. Confidentiality and security

We maintain administrative, technical, and physical safeguards designed to protect Customer Data and Results, including encryption in transit and at rest, access controls, and audit logging. No system is perfectly secure; you agree to use the security features available to you, including strong credentials and two-factor authentication where offered.

9. Term and termination

These Terms apply while you have an account. You may stop using the Service and delete your account at any time from your account settings. We may terminate or suspend your access for material breach, for legal or security reasons, or if the Service is discontinued, with notice where practical.

On termination we will make Customer Data and Results available for export for a reasonable period, after which they will be deleted in accordance with our retention practices, except where retention is required by law.

10. Disclaimers

The Service is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that results will be accurate or complete.

11. Limitation of liability

To the fullest extent permitted by law, neither we nor our suppliers will be liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill, arising out of or related to the Service, even if advised of the possibility. Our total liability for all claims relating to the Service in any twelve-month period will not exceed the amount you paid us for the Service in that period, or one hundred US dollars if you paid nothing.

12. Indemnification

You will defend and indemnify us against claims arising from Customer Data, your use of the Service in violation of these Terms, or your violation of applicable law.

13. Changes to these Terms

We may update these Terms from time to time. We will notify you of changes by email and in the Service. Material changes require your acceptance before you continue using the Service; for other changes, continued use after the effective date constitutes acceptance. The current and previous versions are always available in the Service.

14. Governing law and disputes

These Terms are governed by the laws of the jurisdiction in which we are established, without regard to conflict-of-laws rules. Any dispute will be resolved in the courts of that jurisdiction, unless applicable law requires otherwise.

15. General

These Terms, together with our Privacy Policy and any order or data-processing agreement, are the entire agreement between you and us regarding the Service. If any provision is found unenforceable, the remainder stays in effect. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.

16. Contact

Questions about these Terms can be sent through the contact form in the Service.
