Review after product changes
Update the policy whenever you add analytics, ads, payments, authentication, AI features, location collection, push notifications, or a new customer-support tool.
Review before store submissions
Before submitting to Apple or Google, compare the policy against the app privacy form, data safety form, SDK list, and in-app links. Fix mismatches before review starts.
Review on a fixed schedule
For small apps and websites, a quarterly review is enough. For products with frequent SDK and marketing changes, monthly review keeps compliance from becoming a launch blocker.
