The reference to html2canvas found in the compiled code is a comment banner indicating the library’s origin and version, not a remote service call. – What data is sent: No data is sent. html2canvas is included as a bundled dependency in the public/assets/backend/js/vendor.js file and operates entirely client-side without making external network requests. – When: The library is loaded when the form entries page is accessed in the WordPress admin panel.

No external calls are made. jsPDF (PDFObject CDN Reference) – Service: jsPDF is a JavaScript library bundled within the plugin’s vendor.js file for PDF generation. The library includes an optional feature that can load PDFObject from a CDN, but this feature is only used if the “pdfobjectnewwindow” output type is explicitly called. – What data is sent: The jsPDF library includes a hardcoded fallback URL to Cloudflare’s CDN (https://cdnjs.cloudflare.com/ajax/libs/pdfobject/2.1.1/pdfobject.min.js) that is only used when the optional “pdfobjectnewwindow” output method is called. This is a feature of the jsPDF library itself, not a requirement of this plugin. – When: The CDN URL is only accessed if code explicitly uses jsPDF’s output("pdfobjectnewwindow") method. The plugin does not use this output method by default, so the CDN is not accessed during normal plugin operation. – Source: The library is bundled from npm package jspdf and included in the plugin’s vendor bundle. The CDN reference is part of the jsPDF library’s optional functionality. – Note: To avoid any external CDN calls, do not use the pdfobjectnewwindow output type. The plugin uses other jsPDF output methods that do not require external resources. Important Note: Kali Forms does not send any data without user action or consent to external services, nor do we collect sensitive information from the requests. Email delivery services and payment processing are only used when explicitly configured by the site administrator. JavaScript libraries are bundled within the plugin and operate client-side. The only external CDN reference is an optional feature of the bundled jsPDF library that is not used by default. Development Source Code The source code for Kali Forms is available in the plugin directory. The plugin includes a package.json file that documents all build dependencies and development tools used to compile the plugin’s JavaScript and CSS assets. Build Process Kali Forms uses modern web development tools to build its frontend assets: Webpack: Module bundler for JavaScript and CSS Babel: JavaScript compiler for modern ES6+ syntax Sass/SCSS: CSS preprocessor PostCSS: CSS post-processing with autoprefixer The plugin’s JavaScript source code is located in the resources/assets/js/ directory and is compiled into the public/assets/ directory. The build process does not use code obfuscation or minification that makes code unreadable – only standard webpack production optimizations are applied. Vendor Files The plugin includes bundled vendor libraries in public/assets/backend/js/vendor.js and public/assets/frontend/js/vendor.js. These files contain third-party JavaScript libraries that are compiled and bundled during the build process. A complete list of all vendor dependencies, including their versions and licenses, can be found in the package.json file included with the plugin. The dependencies are categorized as: – dependencies: Runtime libraries required for the plugin to function – devDependencies: Build tools and development dependencies used only during compilation All vendor libraries are bundled locally within the plugin and do not make external network requests during normal operation. The source code for these libraries is available through their respective npm packages, and the bundled versions are included in the plugin distribution. Any CDN references found in vendor files are either: 1. Comment banners or attribution notices (like library name and version information) 2. Optional features within bundled libraries that are not used by the plugin (such as optional output methods that require external resources) For specific examples of how bundled libraries are used and whether they make external calls, see the “JavaScript Libraries (Bundled)” section above. Building from Source To build the plugin from source: Ensure you have Node.js and npm installed Navigate to the plugin directory Run npm install to install dependencies Run npm run prod to build all assets for production, or use specific build commands: npm run prod-frontend – Build frontend form assets npm run prod-components – Build form builder components npm run prod-general – Build general admin assets npm run prod-block – Build Gutenberg block assets npm run prod-form-entries – Build form entries page assets npm run prod-emails – Build email settings assets For development with watch mode, use npm run start or the specific start-* commands.
