OFFICIAL TECHNICAL SUPPORT • TOKYOFLOW iOS & ACADEMYHow do I restore purchases?
In TokyoFlow iOS, open Settings (設定) → Restore Purchases. Your App Store receipt will be validated immediately without additional charges.
Why is there no audio playback during shadowing?
Check if your iPhone physical Silent/Mute switch is turned on, or verify volume sliders in Control Center. You can test native voice synthesis in the in-app audio settings.
Where is my study history and progress stored?
TokyoFlow stores all bookmark data, spaced repetition schedules, and diagnostic recovery logs locally on your Apple device in secure sandbox storage for 100% privacy.
