1. Introduction

4sapi.com ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy describes how we collect, use, and safeguard your information when you use our API gateway and integration services. By accessing or using 4sapi.com, you agree to the terms outlined in this policy.

To provide a stable and secure API routing environment, we collect only the minimum necessary data:

Account Information：Email address and username provided during registration for authentication and essential service notifications.
Financial & Transaction Data：Records of deposits, account balances, and consumption logs used for billing management and reconciliation.
Technical Metadata：When you make a request via our API, we log metadata including request timestamps, model versions used, token counts, and request status (success/failure).

As an API intermediary, we adhere to strict data handling principles:

Non-Persistence (Zero-Storage) Policy：We DO NOT store the content of your API prompts or the resulting completions. All request and response content is processed solely in volatile memory (RAM) and is discarded immediately upon fulfillment of the request.
No Training Policy：We solemnly swear that your data is NEVER used for training artificial intelligence models, nor is it sold to any third party for any purpose.
End-to-End Encryption：All traffic is secured using Enterprise Standard TLS/SSL encryption. Data remains encrypted while in transit from your client to our gateway and from our gateway to the upstream providers (e.g., OpenAI, Anthropic, Google).

The data we collect is used strictly for the following purposes:

Service Operation：To route and process your API requests to the specified upstream providers.
Billing & Accounting：To automatically deduct credits based on your actual token consumption.
Platform Security：To monitor for malicious attacks, fraudulent activities, and to maintain the overall stability of the infrastructure.
Customer Support：To respond to technical inquiries and assist with troubleshooting.

To fulfill your requests, data is forwarded to third-party AI service providers.

Upstream Providers：Including but not limited to OpenAI, Anthropic, Google, and Grok.
Disclaimer：These third-party providers handle data according to their own respective privacy policies. 4sapi.com acts solely as a transmission medium and is not liable for the data handling practices of upstream providers.

Key Encryption：Your 4sapi.com API keys are stored in our database using high-strength cryptographic hashing.
Access Control：Access to our backend infrastructure is strictly restricted to authorized personnel under controlled environments. No personnel can access your dynamic request content.

Management Rights：You have the right to modify your registration information or request the deletion of your account at any time.
Security Responsibility：You are responsible for maintaining the confidentiality of your account password and API keys. 4sapi.com is not liable for any loss of credits resulting from the unauthorized disclosure of your keys.

While we serve users globally, we strive to align our practices with the principles of the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) regarding data minimization and user consent.

We may update this Privacy Policy to reflect changes in our practices or for legal reasons. We will notify you of any significant changes by posting the new version on this page or via email.
