1. Acceptance of Terms

By accessing or using the Stereos platform operated by Atelier Logos LLC ("Stereos," "we," "us," or "our"), you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use our services. If you are using Stereos on behalf of an organization, you represent that you have authority to bind that organization to these terms.

2. Description of Service

Stereos is an enterprise key management and spend operating system for LLM usage. We provide (1) LLM spend management — visibility, metering, and reporting on LLM API usage and costs across your organization — and (2) managed key provisioning — centralized creation, rotation, and governance of provider API keys (e.g., OpenRouter, model providers) at the team level. The service is available through our web application and APIs.

  • You are responsible for maintaining the security of your account credentials.
  • You are responsible for all activity that occurs under your account.
  • You must notify us immediately of any unauthorized use of your account.

4. Subscription and Payment

  • Access to Stereos requires a paid subscription after the 14-day free trial period.
  • Fees include a monthly platform fee plus usage-based charges (e.g., per managed key, per telemetry event) as set forth in our pricing. Platform fees are billed monthly in advance; usage-based charges are billed in arrears.
  • All fees are non-refundable except as required by law or as expressly stated otherwise.
  • We reserve the right to change pricing with 30 days' written notice.

6. Your Data

7. Intellectual Property

The Stereos platform, including its code, design, trademarks, and documentation, is the property of Atelier Logos LLC. The Stereos core software is available under the Elastic License v2. Nothing in these terms grants you rights to our trademarks or branding without prior written consent.

8. Availability and Support

  • We strive to maintain high availability but do not guarantee uninterrupted access to the service.

Our total liability for any claim arising from these terms or the service shall not exceed the amount you paid us in the 12 months preceding the claim.

10. Disclaimer of Warranties

The service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be error-free or uninterrupted.

11. Indemnification

You agree to indemnify and hold harmless Stereos and its affiliates from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising from your use of the service or violation of these terms.

12. Termination

  • We may suspend or terminate your account for violation of these terms or non-payment.
  • Upon termination, your right to use the service ceases immediately.
  • Sections regarding liability, indemnification, and governing law survive termination.
