Policy baseline
- Apple App Store Review Guidelines
3.1.1: disclose randomized virtual-item probabilities. - Google Play policy: provide clear randomized-item disclosure near transaction/opening surfaces.
- Regional disclosure enforcement context (including Korea/China) informs stricter disclosure discipline.
Ratings and descriptor consistency
- ESRB/PEGI random-item descriptor language should remain consistent with in-app disclosure copy.
- In-app wording must avoid deterministic claims unless a backend guarantee explicitly exists.
Required implementation outcomes
- Odds are presented from backend payloads, not hardcoded.
- Disclosure is visible or one-tap accessible close to purchase/open actions.
- Failure states provide user-actionable, non-misleading feedback.
Disallowed patterns
- Implied guaranteed rarity without explicit backend guarantee.
- Marketing language that overstates random-outcome certainty.
- Hidden or hard-to-reach disclosure UI paths.
