The record

Product: FoldCode is a native, offline-capable Android development environment combining an editor, terminal, build tools, language intelligence, debugging, Git, web preview, and Raspberry Pi Pico development.
Supported work: FoldCode supports C/C++, Python, Rust, web development, and Raspberry Pi Pico projects.
Editor: The editor includes multiple tabs, split editing, syntax highlighting, diagnostics, code completion, breakpoints, and mouse and keyboard support.
Local development: Builds and execution run on the device without a remote build service, and editing and local builds can work offline after extensions and project dependencies are installed.
Git and web: FoldCode supports local Git repositories, HTTPS Git operations, a local WebView browser, and web project previews.
Language packages: Optional extensions provide C/C++, Python, Rust, web development, GNU Arm Embedded, Fortran and COBOL, and Raspberry Pi Pico toolchains.
Pico features: Pico support includes CMake/Ninja builds, MicroPython, UF2 generation, and USB flashing when the Android device supports USB host/OTG.
Integrations: The README names HTTPS Git operations, npm and pip, CMake project dependencies, and Raspberry Pi Pico hardware flashing as supported connections or workflows.
Privacy: FoldCode says it includes no advertising, analytics, or telemetry SDKs, disables Android application backup, and has no extension catalog URL or automatic extension downloads in the production build.
Network security: The release APK rejects external cleartext network traffic, allows loopback HTTP for local previews, and keeps WebView remote debugging off unless an active IDE browser-debug session is explicitly started.
Package validation: FoldCode validates extension manifests, legal metadata, payloads, paths, byte counts, checksums, and minimum host version before activating a package.
Requirements and limits: FoldCode 1.0.0 requires Android 8.0 or newer on an ARM64 device and All files access for its shared workspace; Android 11 and newer require granting that special permission.
Availability and license: The maker provides a signed Android APK and extension packages through a GitHub release, and the project is licensed under Apache License 2.0.
Maker: The repository credits copyright to Myroslav Poliakov.
