Three Modules That Carry the Whole Product

The site’s value lives in three integrated modules — card key generation, encryption-gated access, and renewal handling — and they share one user table so billing stays consistent.

• Card key system: Admins mint time-limited keys (7/30/90 days by default) from the backend; each binds to one device fingerprint, which I confirmed by inspecting the licenses table.
• Access encryption layer: A token check runs before the AI endpoint answers; bypassing it just returns a blank response, so protection is gate-level rather than content-level.
• Site renewal workflow: Users see a countdown and paste a new key to extend without re-registering — useful for retention on small commercial demos.

Actionable takeaway: rename admin.php before going live; the default path is the first thing scanners hit.

Deploying on a PHP 7.4 Host in 6 Steps

Deployment is genuinely one-upload-and-go, but 3 configuration steps will silently break the card module if you skip them.

1. Upload the package to your webroot via FTP or file manager.
2. Create a MySQL 5.6+ database and import the included .sql file.
3. Edit /config/database.php with your DB host, name, user, and password.
4. Visit /install.php once to write the config
