Privacy Policy

Last updated: 3/25/2026

1. Information We Collect

PromptGuard ("we", "our", or "us") collects information that you provide directly to us, such as when you create an account, use our services, or communicate with us.

  • Account Information: Name, email address, and authentication credentials.
  • Usage Data: Information about how you interact with our API gateway, including request volumes, routing metrics, and performance data.
  • Prompt Data: The content of prompts sent through our gateway for filtering, routing, and caching purposes. This data is handled according to your configuration settings.

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our services to you.
  • Process transactions and send related information.
  • Provide technical support and customer service.
  • Monitor and analyze trends, usage, and activities in connection with our Services.
  • Detect, investigate, and prevent malicious activity, security incidents, and other illegal activities.

3. Data Security and Privacy

Security is a core component of PromptGuard. We implement reasonable and appropriate security measures to protect your information from unauthorized access, alteration, disclosure, or destruction. We do not use your prompt data to train our own models without your explicit consent.

4. Open Source Transparency vs. Proprietary Engines

PromptGuard operates on a hybrid model to ensure trust and security while delivering advanced capabilities:

  • Open Source API Gateway: Our API gateway code is entirely open source. We do this for complete transparency, allowing you (and the community) to audit the code and verify that we do not capture, log, or steal your API keys.
  • Closed Source Engine: The core intelligence engine—which handles prompt fitting, analytics, routing logic, and PII (Personally Identifiable Information) removal—is proprietary and closed source.
