Your hours are yours.
— “I watch the clock, not you.”

Everything stays on your device.
Sage Fox is built on Apple's Screen Time framework (FamilyControls, DeviceActivity, and ManagedSettings). All usage measurement happens on your iPhone, inside Apple's system — your screen-time data is never uploaded, synced, or shared. There is no analytics service watching how you use your apps.
We can't see which apps you guard.
When you choose apps for Sage to watch, Apple hands the app opaque tokens — not app names or identifiers. This is a deliberate property of the Screen Time API: even Sage Fox itself cannot tell which apps you selected, and neither can we.
Game results stay local too.
Your duels against the fox — wins, losses, attempts per day — are counted only on your device, so the app can show you today's record. These counters never leave your phone.
Subscriptions go through Apple.
Purchases are processed by the App Store, and subscription status is managed through RevenueCat, our billing provider. That involves an anonymous app-user identifier and your purchase state — never your screen-time data, your guarded apps, or your game history. We don't receive your name, email, or payment details.
Notifications are quiet and local.
Sage sends at most a gentle local reminder — for example, a morning nudge to set today's limit. These are scheduled on your device; there is no push-notification server.
