Privacy
Service Providers
These companies process data to help operate Sayelle. The exact data depends on the features you use, your subscription, region, and privacy choices. Depending on the service and applicable law, a provider may act as our processor or as an independent controller under its own privacy terms—for example, an app-store operator handling a purchase. This list will be updated when providers change.
