Terms of Service
Last updated June 2026
1. Agreement to terms
These Terms of Service (“Terms”) are a legally binding agreement between you (“Customer,” “you”) and Black Gibbon Ltd(“Retanu,” “we,” “us”) governing your access to and use of the Retanu platform, including the console, gateway, admin API, and any related services (collectively, the “Service”).
By creating an account or using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms, and “you” refers to that organization.
2. Description of the Service
Retanu is an inference ops management platform that routes requests to third-party inference providers (such as OpenAI, Anthropic, DeepInfra, and Google) on your behalf. The Service provides:
- Automatic model selection and routing across multiple providers
- Per-workspace spend caps, rate limits, and budget enforcement
- Usage metering, cost attribution, and reporting
- Organization-level data isolation enforced at the database level
- An OpenAI-compatible API gateway
- A web-based console for configuration and monitoring
Retanu does not itself provide inference models. We route your requests to the providers you configure using the API keys you supply.
3. Account registration
You must create an account to use the Service. You agree to provide accurate and complete information, keep your credentials secure, and notify us immediately of any unauthorized access to your account.
You are responsible for all activity under your account, including activity by users you invite to your organization. We are not liable for losses arising from unauthorized use of your account credentials.
4. Provider keys and BYOK
The Service operates on a bring-your-own-key (“BYOK”) model. You supply API keys for the inference providers you wish to use. By providing these keys, you represent that:
- You have the right to use those keys and the associated provider accounts.
- Your use of providers through Retanu complies with each provider's terms of service.
- You are solely responsible for all charges incurred with inference providers.
We store your provider keys encrypted and use them solely to route your inference requests. Keys are never written to application logs. You can revoke or delete keys at any time through the console.
5. Workspaces and data isolation
You may create workspaces within your organization, each representing a sub-unit (e.g., a client, team, location, or project). Each workspace receives its own API endpoint, credentials, budget controls, and usage tracking.
Data belonging to your organization is isolated from other organizations at the database level using row-level security. We do not access, use, or share your organization's data except as necessary to provide the Service or as described in our Privacy Policy.
6. Acceptable use
You agree not to use the Service to:
- Violate any applicable law, regulation, or third-party rights.
- Circumvent or attempt to circumvent budget controls, rate limits, or other safety mechanisms.
- Interfere with or disrupt the Service or its infrastructure.
- Reverse-engineer, decompile, or attempt to extract the source code of the Service.
- Use the Service to transmit malware, spam, or other harmful content.
- Resell access to the Service without our prior written consent.
- Use another organization's API keys, credentials, or data without authorization.
- Abuse inference provider accounts or violate their acceptable-use policies.
We reserve the right to suspend or terminate your account if we reasonably believe you are violating these Terms or engaging in activity that harms the Service or other users.
7. Fees and payment
Early access. During the early-access period, the Starter plan is available at no charge. We will provide at least 30 days' notice before introducing or changing fees for your plan.
Paid plans. If you subscribe to a paid plan, fees are billed in advance on a monthly or annual basis. All fees are non-refundable except as required by law. We may change pricing with at least 30 days' notice; if you do not agree to the new pricing, you may cancel before it takes effect.
Provider charges. Retanu does not charge a surcharge on inference provider usage. Providers bill you directly at their standard rates based on the API keys you supply. You are solely responsible for all provider charges.
8. Intellectual property
Our IP. We own all rights in the Service, including its software, design, documentation, and trademarks. These Terms do not grant you any rights to our intellectual property except the limited right to use the Service as described here.
Your data. You retain all rights to the data you submit to or generate through the Service, including organization configuration, workspace settings, and inference content. We claim no ownership of your data.
Feedback. If you provide feedback or suggestions about the Service, we may use them without obligation to you.
9. Inference content
You are solely responsible for the content of inference requests you send through the Service and for compliance with applicable laws regarding that content. We do not monitor, review, or moderate inference content.
By default, Retanu does not store inference request or response content. Only routing metadata (model, cost, latency, token counts) is retained. If you enable content logging for a workspace, you are responsible for ensuring that doing so complies with your legal obligations, including any obligations to your end users.
10. Service availability
We aim to provide a reliable service but do not guarantee uninterrupted or error-free availability. The Service may be temporarily unavailable for maintenance, upgrades, or circumstances beyond our control.
If your plan includes an SLA with uptime commitments, the terms of that SLA supplement these Terms. In the event of a conflict between the SLA and these Terms, the SLA controls with respect to availability commitments.
11. Limitation of liability
To the maximum extent permitted by law:
- The Service is provided “as is” and “as available” without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, and non-infringement.
- We are not liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or goodwill, arising out of or related to your use of the Service.
- Our total aggregate liability for all claims arising out of or related to these Terms or the Service is limited to the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) USD $100.
- We are not liable for any charges, losses, or damages arising from your use of third-party inference providers, including provider outages, billing disputes, or data handling by providers.
12. Indemnification
You agree to indemnify and hold harmless Black Gibbon Ltd, its officers, employees, and agents from and against any claims, damages, losses, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any law or third-party rights; or (d) the content of inference requests you send through the Service.
13. Term and termination
Term. These Terms are effective when you create an account and remain in effect until terminated.
Termination by you. You may close your account at any time by contacting us or through the console. Upon closure, your right to use the Service ends immediately.
Termination by us. We may suspend or terminate your account if you breach these Terms, if we are required to do so by law, or if we discontinue the Service. We will provide reasonable notice where possible.
Effect of termination. Upon termination, we will delete your account data within 30 days, except where retention is required by law. Provider keys are deleted immediately. Sections 8, 11, 12, 14, and 15 survive termination.
14. Governing law and disputes
These Terms are governed by the laws of Singapore, without regard to conflict-of-law principles. Any disputes arising from these Terms or the Service will be resolved through binding arbitration administered by the Singapore International Arbitration Centre (SIAC) under its prevailing rules. The arbitration will be conducted in English in Singapore.
Nothing in this section prevents either party from seeking injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.
15. Changes to these Terms
We may update these Terms from time to time. If we make material changes, we will notify you by email or by posting a notice in the console at least 30 days before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms. If you do not agree to the changes, you must stop using the Service and close your account.
16. General
- Entire agreement. These Terms, together with our Privacy Policy and any applicable Data Processing Addendum, constitute the entire agreement between you and us regarding the Service.
- Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in full force.
- Waiver. Our failure to enforce any provision does not constitute a waiver of that provision.
- Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of our assets.
- No third-party beneficiaries. These Terms do not create any rights for third parties.
