Terms of Service

1. Acceptance of Terms

By accessing or using Sentinel Proxy ("the Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

2. Service Description

Sentinel Proxy is an AI Firewall (AIF) that inspects prompts sent to large language models (LLMs) for prompt injection attacks. The Service operates as a reverse proxy between your application and your upstream LLM provider, scanning requests in real time and taking action (clean, neutralize, or block) based on detected threat levels.

3. Zero Data Retention

4. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose or to facilitate illegal activity
• Attempt to bypass, disable, or interfere with the Service's security mechanisms
• Reverse engineer, decompile, or attempt to extract the source code of the threat detection engine
• Exceed your plan's rate limits through automated means or abuse the Service infrastructure
• Resell or redistribute access to the Service without written authorization

5. API Keys and Account Security

You are responsible for safeguarding your API keys. API keys are shown only once at creation and are stored as irreversible SHA-256 hashes. Treat your keys as secrets—do not commit them to public repositories or share them in plaintext. You are responsible for all activity that occurs under your API keys. Notify us immediately if you believe a key has been compromised.

6. Subscription and Billing

Paid plans are billed monthly through Stripe. You may cancel or change your plan at any time through the billing portal on your settings page. Downgrades take effect at the end of the current billing period. No refunds are provided for partial months. The free Starter tier requires no credit card and has no time limit.

7. Service Availability

The Service is provided on an "as is" and "as available" basis. We make commercially reasonable efforts to maintain uptime but do not guarantee uninterrupted availability. We are not liable for any losses caused by service downtime, latency, or false positives/negatives in threat detection.

8. Limitation of Liability

To the maximum extent permitted by law, Sentinel Proxy and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or business opportunities, arising from your use of or inability to use the Service. Our total liability for any claim shall not exceed the amount you paid us in the twelve months preceding the claim.

9. Termination

We may suspend or terminate your access to the Service at any time for violation of these terms, abuse of the platform, or non-payment. You may terminate your account at any time by cancelling your subscription and deleting your API keys. Upon termination, your usage data will be deleted in accordance with our retention schedule.

10. Changes to Terms

We may update these terms from time to time. Material changes will be communicated via the email associated with your account. Continued use of the Service after changes take effect constitutes acceptance of the updated terms.
