Every guide and game page on Zone4APK is written by the site's editors and checked against the actual software it describes. This page documents how that works, because "trust us" is not a sourcing policy.
Game pages are generated from structured release data: the file's scan results, fingerprint, measured size, tested Android version, and the contributor's changelog. When that data is missing, the page says so instead of inventing a value — you will see "unknown" rather than a made-up number.
Guides are written from hands-on testing: the install walkthroughs were performed on real devices running current Android versions, and re-tested when Android changes something material. Where a guide describes third-party tools, those tools are named and linked to their original source, never re-hosted.
Factual errors in a guide are fixed in place and noted in the page's updated date. Errors in release data (wrong version, wrong size, wrong feature list) are corrected on the game page and reflected in the version history. If you spot an error, email cpaernest@gmail.com — corrections are treated as priority mail, ahead of general support.
Releases are contributed by a small set of known builders and reviewed by an editor before publication. Review text on a release comes from whoever performed the install test. We name scan vendors (VirusTotal) rather than vaguely claiming a file is "checked." When a release was tested by its own author rather than an editor, the version history shows it.
