What happens next
Checkout places a card authorization before any upload. After you confirm the checkout email, you can upload the two drawing PDFs, review metadata-only preflight results, and choose whether to charge your card and start generation.
What happens to your documents
Your documents are deleted the moment your report is generated. No human ever reads them. They are never used to train anything. Your prices are stripped before analysis and never reach a model. What we keep is a cryptographic fingerprint of what you sent, the findings, and the audit trail — enough to prove your report matches your documents, and nothing more.
