Before you buy

The fine print, in plain English.

Licence

One named person or legal entity. Build unlimited own and client projects, modify it freely and deploy commercially. Your branding, content, data and original code are yours; the reusable Simple Stack source remains licensed and can't be redistributed as a template or standalone source product.

Updates

Lifetime access to the version you buy — re-download any time. If we ship a meaningful update, buyers are emailed so you can grab it; future updates aren't guaranteed or part of the price.

Requirements

A supported PHP release (8.3+ recommended), SQLite and Composer. Native source templates require Xcode or Android Studio, provider configuration, signing and device testing. The web app has no Node or frontend build step. Hosting, email and payment-provider charges are separate.

Cancellation & faulty content

Before Checkout you expressly request immediate supply and acknowledge that the 14-day change-of-mind cancellation right ends when supply begins. This does not affect your statutory rights if the content is faulty, not as described, unfit for a stated purpose or cannot be supplied.

After payment

Stripe emails your receipt, we email a sign-in link and code, and the download is waiting in your account. No account needed up front.
