App Store Review Guidelines

1. Safety

When people install an app from the App Store, they want to feel confident that it’s safe to do so—that the app doesn’t contain upsetting or offensive content, won’t damage their device, and isn’t likely to cause physical harm from its use. We’ve outlined the major pitfalls below, but if you’re looking to shock and offend people, the App Store isn’t the right place for your app.

  • 1.1 Objectionable Content Apps should not include content that is offensive, insensitive, upsetting, intended to disgust, or in exceptionally poor taste. Examples of such content include:
    • 1.1.1 Defamatory, discriminatory, or mean-spirited content, including references or commentary about religion, race, sexual orientation, gender, national/ethnic origin, or other targeted groups, particularly if the app is likely to humiliate, intimidate, or place a targeted individual or group in harm’s way. Professional political satirists and humorists are generally exempt from this requirement
