The parts that usually come attached to a free plugin, and do not here.
No account
Nothing to register, no licence key to paste. Install from your own admin and activate.
No telemetry
No analytics, no usage pings, no phoning home. The plugin talks to your site and nothing else.
No fee per sale
Sell one ticket or fifty thousand. The plugin costs the same either way, which is nothing.
No build step
Every shipped file is unminified, readable source. What you download is what runs.
GPLv2 or later
Fork it, change it, ship your own version. The licence WordPress itself uses.
Current WooCommerce
Tested against HPOS and the block cart and checkout, not just the classic templates.
