Common questions.

Is the free plan actually free?+
Yes. The Starter plan gives you 35 rules and 3 scans per day with no credit card required. Upgrade to Team for all 78+ rules and unlimited scans.
What frameworks and languages are supported?+
Oncecheck scans any iOS project (Swift, ObjC, Flutter, React Native, .NET MAUI), Android project (Kotlin, Java, Flutter, React Native), or Web project (React, Next.js, Vue, Svelte, Angular, plain HTML). The platform is auto-detected from your project structure.
Does it need network access?+
No. Oncecheck runs entirely on your machine as pure static analysis. Your source code never leaves your device. The only network call is a lightweight scan counter for plan limits.
Does a passing scan guarantee approval?+
No. Scan results are advisory — they catch common compliance issues but don't constitute legal advice or certification. App store reviews consider factors beyond automated scanning.
