If you're an individual you may use Delphi Community Edition to create apps for your own use and apps that you can sell until your revenue reaches $5,000 per year.

If you're a small company or organization without revenue (or up to $5,000 per year in revenue), you can also use the Delphi Community Edition. Once your company's total revenue reaches US $5,000, or your team expands to more than 5 developers, you can move up to an unrestricted commercial license with Professional edition.

Community Edition is licensed for 1 year (renewable) of limited commercial use until your individual or company yearly revenue reaches 5,000 USD or your development team expands to more than 5 developers.
