What types of discharge (involuntary/voluntary)?

User churn is divided into two main types:

1. Voluntary churn — when a user consciously stops using a product or service. For example, cancels a subscription, deletes an app, or refuses a service.

2. Involuntary churn — when a user is lost due to external reasons unrelated to their desire. For example, payment failure due to card issues, technical failures, billing errors, or an account being mistakenly blocked.

Understanding these types helps product managers develop retention strategies: for voluntary churn — improve the product and communication, for involuntary — optimize payment processes and support.
