Security and Packaging

Passwords are protected with bcrypt using password_hash and password_verify. The backend also includes admin authorization checks, listing ownership validation, and MIME-validated image uploads with randomized filenames.

The buyer package excludes build output, Flutter cache folders, IDE files, Git metadata, PHP vendor files, Node.js node_modules, Android signing files, Firebase service files, private tokens, real user data, and local environment files. The included SQL contains safe demo data, stores demo passwords as bcrypt hashes, and contains no stored authentication tokens.

Important: Some features require separate buyer-owned third-party accounts, including Firebase, Google Sign-In, Google Cloud, map or tile providers, hosting, domain registration, SSL, Redis hosting, SMTP or email services, notification services, Google Play services, and any payment or subscription provider enabled by the buyer. Some providers may offer free tiers, but additional charges can apply depending on the selected plan, region, traffic, storage, usage volume, or transaction volume.
