What TrustCheck does
TrustCheck is a Chrome extension that helps you assess whether online claims are credible before you believe, share, or act on them. When you highlight a claim and submit it for checking, your selected text and limited page context are sent to TrustCheck's backend for analysis. The backend may forward the content to an AI provider to generate a credibility assessment.
What data is processed
When you submit a claim for checking, TrustCheck processes the following:
- Selected claim text — the text you highlighted on the webpage.
- Page URL, domain, and title — basic context about where the claim appeared.
- AI provider processing — your claim text may be sent to a third-party AI provider to generate the credibility assessment. TrustCheck does not control the AI provider's data handling; refer to the AI provider's own privacy policy for details.
-
Local browser storage — recent checks and Proof Receipts are stored
locally in your browser using
chrome.storage.local. This data stays on your device and is not sent to TrustCheck's servers.
What you should not submit
Do not use TrustCheck to check passwords, private messages, confidential documents, medical records, or any sensitive personal information. Selected text is sent to TrustCheck's backend and AI provider for analysis. Only submit claims you would be comfortable sharing externally.
API keys
API keys are never exposed in the extension. All AI processing happens through TrustCheck's backend, not directly from your browser. The extension does not contain or transmit any API credentials.
