**There is no universal legal age.** It depends on the platform, payment processing, and local contract law.
| Platform | Minimum Age for Developer Account | Notes |
|---|---|---|
| Apple App Store (iOS/macOS) | 18 | Apple Developer Program requires legal adult to sign contract. Minors need parent/guardian to enroll as "Organization" (D-U-N-S) or use parent's account. |
| Google Play Store (Android) | 18 | Google Play Console requires 18+ for merchant account (payments). Family Link accounts cannot publish paid apps. |
| Steam (Valve) | 18 | Steamworks agreement is a legal contract. Minors need parent/guardian to sign & handle taxes/banking. |
