What do I receive after purchase? A ZIP download you run yourself. It includes setup instructions and example configuration so you can validate your first run quickly.

Does this require any monthly fees? No monthly fees for the software. If you connect to third‑party APIs (email providers, SERP APIs, etc.), those vendors may charge usage-based fees.

Do I need API keys or credentials? If the product integrates with third‑party platforms, yes — you’ll provide your own credentials so everything runs under your account.

What tech does it use? Language: Python 3.10+ or PHP 7.4+ (plus standard dependencies listed in the package).

This is a one-time purchase. You download the software and run it on your own machine or server. If the product integrates with third-party APIs, those providers may have their own usage costs.
