Vectinous — Privacy Policy

Effective date: 10 July 2026

Vectinous is a browser extension that estimates how much an AI chatbot's answer depends on the wording of your question. This policy explains exactly what data it touches and where that data goes. It is intentionally short because the extension is intentionally simple.

What the extension stores

• Your OpenRouter API key — saved only in your browser via chrome.storage.local. It is used solely to authenticate your own requests to OpenRouter. It is never sent to the developer or to any server other than OpenRouter.
• The floating button's position — a small preference saved locally so the widget stays where you put it.

What the extension sends, and to whom

When you click Check stability, the question you entered (and several reworded variations of it that the tool generates to measure framing) is sent to OpenRouter (openrouter.ai), which forwards it to a large language model to be scored. This is the only external service the extension contacts, and it happens only when you actively run a check. OpenRouter's handling of that request is governed by their own privacy policy.

What the extension does NOT do

• It does not collect analytics, telemetry, or usage tracking.
• It does not send any data to the developer. There is no developer-operated server.
• It does not sell or share your data with third parties.
• It does not read or store your page content except the single question you choose to analyze, at the moment you ask it to.
• It does not load or execute any remote code; all code ships inside the extension.

Data retention

Your API key and preferences remain in your browser until you remove them (via the extension, or by uninstalling it). The developer stores nothing.
