Gate any feature from any backend. Tierux verifies purchases with the store and returns normalized entitlement state — one REST call, no client-side secrets.
| Capability | With Tierux | Without Tierux |
|---|---|---|
| Store verification | Server-side via Android Publisher / StoreKit 2 JWS | Manual API calls, per-platform logic |
| Token storage | Hashed for dedup, AES-256-GCM encrypted for refresh | Custom — often raw tokens in plain DB columns |
| Entitlement state | Normalized (active/expired/grace) across Android + iOS | Ad-hoc, platform-specific parsing |
| Multi-platform | One API, same response shape | Separate code paths per store |
| Server integration | REST — any language, any backend | Custom middleware and store SDKs |
| RTDN / webhook processing | Auto-processed — renewals, expiries, cancellations | Must build and maintain Pub/Sub + App Store Server Notifications |
| Pricing model | Flat monthly fee, no revenue tax | % of tracked revenue or free — but dev time is expensive |
