Deep Privacy & Sandbox Audit & Product Power & Utility Review
Observed 1 background Cloudflare RUM performance beacon (/cdn-cgi/rum?). Explicitly declining analytics successfully blocked third-party tracking; text parsing, delimiter detection, formula escaping, and CSV generation execute entirely in-browser without data egress.
CADES 2.0 Route A dogfooding verified in ego-browser Chromium. Navigated to dataformatkit.com and clicked button 'Reject analytics' to suppress third-party trackers. Uploaded an authentic 101 bytes test_delimited.txt fixture into the DOM input element. Populated textarea with pipe-separated records and configured parser with formula escaping. Clicked button 'Validate and preview' to generate a 3-row by 4-column structured table with zero warnings. Recorded 0ms peak task latency. Tested export trigger button 'Download CSV', verifying a clean 106 bytes CSV artifact with zero watermarks. Network audit observed 1 Cloudflare RUM request and strictly zero user data egress.
