Your documents are serious. Here's exactly how we treat them.

What happens when you upload

• Your document travels over encrypted connections (HTTPS/TLS) and is stored with server-side encryption (AWS S3).
• Your account and session are protected by Firebase Authentication; your analyses are yours, tied to your account.
• The analysis runs for you — the output is a private report in your dashboard, not content shown to anyone else.

Why you can check the AI's work

• Every finding cites its source. Risk flags quote the exact clause from your document, so you can verify each one in seconds.
• Confidence is shown, not hidden. When Main AI is less certain about a document's type, it says so — right on the analysis and in the exported report.
• Facts and judgment are separated. Reports distinguish what the document says from what we recommend you do about it, and always include a "verify with a human" section.

What Main AI will never pretend to be

Main AI is document intelligence, not a law firm, medical provider, or financial advisor. It prepares you to act — organized facts, deadlines, drafts, and questions worth asking a professional — and is explicit about where a professional should take over. High-stakes decisions deserve both: a fast, thorough first read and qualified human judgment.

Security controls you can verify yourself

These are enforced at the transport layer on every response — you can confirm them with your browser's network inspector or a tool like curl -I.

• HTTPS is enforced. Strict-Transport-Security is set for two years with includeSubDomains; preload, and insecure requests are upgraded automatically.
• The site can't be framed. X-Frame-Options: SAMEORIGIN plus a CSP frame-ancestors 'self' block clickjacking.
• A strict Content-Security-Policy limits what scripts and connections are allowed, with object-src 'none' and base-uri 'self'.
• No MIME-sniffing, minimized referrers, and camera/microphone/geolocation disabled via Permissions-Policy.
• Card details never touch our servers — payments are handled by Stripe; authentication by Firebase.

What we don't claim

Trust is easier to give when a product is honest about its limits. Main AI does not claim formal security certifications (such as SOC 2 or ISO 27001), independent penetration-test attestations, or end-to-end encryption of document content beyond encryption in transit and at rest. If we ever earn those, we'll say so here — and only here, once it's true.
