Trust & Security

Your data. Your keys. Your control.

We built CrossCheck with privacy as a foundational principle, not an afterthought.

Bring Your Own Keys

Your Browser → AI Providers (direct)

CrossCheck → Analysis (local)

Results → You (only you)

Your API keys stay in your browser.

We never see, store, or transmit them.

In BYOK mode, your queries go directly from your browser to AI providers using YOUR API keys. We never see your prompts, responses, or keys.

We will never sell your data. Period. Not to advertisers, not to AI companies, not to anyone.

We collect only what's needed to improve the service — and always with your consent.

API keys encrypted with WebCrypto API in your browser. AES-256-GCM.

We're building with EU AI Act compliance in mind from Day 1.

While CrossCheck itself is not a "high-risk AI system," we help users who work WITH high-risk AI to verify and document their results.

What this means for you:

Audit trail: every verification session is timestamped with model versions and confidence scores
Exportable reports: generate documentation compatible with compliance requirements
Transparency: you always see which models were used, what they said, and where they disagreed

No Google Analytics. No Facebook Pixel. No tracking.
