Product identity
Go Flipbooks™ by CrownThrive is the platform. Real3D is a reader implementation dependency; FlipLink is a managed provider rail; Stripe is a commerce provider; Mailgun is a communications provider; AdLuxe is an advertising rail; CHLOM is a governance and rights system; and CIE is an intelligence and governance layer.
Reader components
The inspected Real3D 4.20 distribution includes PDF.js 3.11.174, Three.js r111, mark.js 9.0, an iScroll 5.2 snapshot, MOD3 1.0.0, and Adobe CMap resources. The repository currently carries the Adobe CMap notice; a complete SBOM and third-party notice bundle has not yet been certified.
Reader network boundary
The licensed Real3D 4.20 PDF reader performs a browser-side domain check at check.real3dflipbook.net whenever a PDF reader initializes. It sends the current hostname and a per-load pseudorandom identifier; Real3D also observes ordinary HTTPS metadata such as reader IP address, user agent or client hints, Origin, and potentially an origin-only referrer. The Content Security Policy permits only that exact Real3D check host, not a Real3D wildcard.
No source transfer
Creators receive Go Flipbooks services, authorized entitlements, embeds, APIs, and deployment capabilities according to plan and contract—not unrestricted vendor or platform source.
