Everything Sylph does ships inside the app. Every technique, theme and sound lives on your device — nothing streams, nothing is collected. No streaks, no history, no accounts, ever.
The only times Sylph touches the network are Google Play's billing for the one-time purchase, and casting to your TV if you use it. Read the whole privacy story →
