Frequently Asked Questions
How much of churned customers can be saved?
Depends on sector. SaaS average: 5-8% monthly churn (50-80% annual). Good sub-models hit 2-3%. Win-back campaigns help.
GDPR compliance for subscriptions?
Customer data (excluding card) on your servers, card data with iyzico/Stripe. When user asks to delete subscription, all data wiped (excluding legally required retention).
Free trial conversion rate?
Industry average 15-25%. Good paywall design + onboarding pushes to 30-40%. We A/B test continuously.
How to avoid Apple/Google 30% fee?
Digital subscriptions in apps must use Apple/Google IAP (30%). Physical goods or services (in-person visits, books, off-app meetings) can use own payment system.
