Privacy Policy

BYOK Multi-LLM Benchmarker (“the extension”) is a Chrome side panel that compares language models using API keys you provide.

API keys and prompts

Vendor API keys are stored only in chrome.storage.local on your computer. Prompts and model outputs are stored in IndexedDB on your computer. They are sent only to the vendors you choose (OpenAI, Anthropic, Google Gemini, Groq) when you run a comparison. We do not operate a proxy and we do not receive your vendor keys or prompt text.

License purchases

If you buy Pro, payment is processed by Stripe. After payment, a license key is generated on our license worker. Stripe may send us your checkout email so we can email you the key and let you recover it. The extension sends only the license key and a random device id to that worker when you Activate. It never sends vendor API keys to the worker.

No accounts

The extension does not create a user account with us. There are no content scripts on websites you visit.
