HTMLPlayForge

An offline HTML, CSS and JavaScript editor with live preview for Android.

• Package: com.htmlplayforge.app, version 1.0.1, Android 8.0 and newer
• No permissions, no internet access, no trackers, no ads
• Signed release APK, not minified (the code is readable)
• Built only by GitHub Actions (.github/workflows/build-apk.yml)

Read GUIDE.md first. It tells you, step by step, how to build and publish the app from your phone.

What you can check yourself

Every release has four files: the APK, its .sha256, TRUST_REPORT.md and SIGNING_CERT.txt. TRUST_REPORT.md lists permissions (none), tracker libraries found (none), web addresses in the code, native files (none) and the libraries used. The build fails if any of these rules is broken. These are facts, not a promise that the app has no bugs.
