Local-only validation is vulnerable to receipt manipulation, clock exploits, and does not sync across devices. Server-side entitlement management through tools like Botsi provides a single source of truth for subscription status, works across platforms, and updates in real time when billing events occur.
A backend entitlement system maps subscription products from both Apple and Google to unified entitlement identifiers. When a user subscribes on iOS and logs into Android, the server checks their entitlements and grants the same access regardless of platform. Botsi handles this cross-platform mapping automatically.
When a subscription lapses, the backend should revoke premium entitlements either immediately or after a configured grace period. Server-to-server notifications from Apple and Google inform your backend of status changes in real time, so access can be adjusted within seconds of a cancellation or billing failure.
User engagement that occurs without directly launching the app, such as interacting with push notifications, widgets, or voice assistants. While less visible, this activity can influence retention and should be factored into engagement metrics.
A statistical approach that updates probabilities based on new evidence, often used in A/B testing and predictive modeling. Unlike frequentist methods, Bayesian models provide a more flexible framework for interpreting test results and making probabilistic decisions — useful in pricing tests, LTV projections, and paywall optimization.
The practice of grouping users based on in-app behavior — such as content viewed, session frequency, or purchase history — to tailor messaging, paywalls, and retention strategies. Behavioral segmentation enables personalized user experiences and drives more efficient monetization.
The interval at which a subscription renews and the user is charged — typically monthly, quarterly, or annually. Understanding billing cycles is important for tracking revenue recognition, renewal trends, and user lifetime value.
The automated process by which subscription platforms (e.g., Apple, Google, or a backend service) attempt to recover failed payments due to issues like expired cards or insufficient funds. Effective retry logic is essential for reducing involuntary churn and maintaining revenue continuity.
