1. Never use misleading claims in metadata (title, description, screenshots) - avoid words like "official", "the only", "number one", "free", etc. 2. In-app functionality must exactly match your store listing - no "bait and switch" between what is advertised and what users actually get. 3. Permission requests must explain their purpose in context; do not "bundle" permissions to obtain access. 4. Run a full user-journey audit before submission so every step of the flow matches the description and the real experience. 5. If your app serves algorithmically recommended content, disclose the recommendation mechanism in a prominent location.
