Runner Lock Privacy Policy

This policy reflects the data practices of Runner Lock version 1.0.4 and later.

Effective date: August 20, 2026

Last updated: September 6, 2026

Runner Lock ("Runner Lock," "we," "us," or "our") is provided by yui.ai, located at Seoul, Korea.

Runner Lock is designed to turn distracting app time into a movement habit. The app lets you schedule a Daily Lock for selected apps and unlock them after Runner Lock verifies either a qualifying workout in Apple Health or your arrival at a destination you saved.

This Privacy Policy explains how Runner Lock processes information. Runner Lock currently has no user accounts, advertising, or cross-app tracking. Health, Screen Time, location, Daily Lock, and recent activity information is processed primarily on your device. Runner Lock operates a limited feedback service and uses RevenueCat to validate App Store purchases, manage subscription entitlements, restore purchases, and provide subscription analytics. Apple separately processes information when it provides system services such as HealthKit, Screen Time, MapKit, notifications, and App Store purchases.

Privacy at a glance

This summary is designed to make the policy easier to understand. The detailed sections below provide the controlling description.

• Health and workouts: Runner Lock reads only the Apple Health workout details needed to check your rule. Raw workout records are evaluated on your device and are not copied to Runner Lock's feedback server.
• Location: Runner Lock requests your current location when you initiate a destination check. The comparison happens on your device; Runner Lock does not continuously track you or create a route history.
• Screen Time: Your selected apps and raw activity information are handled through Apple's privacy-preserving Screen Time frameworks and remain on your device.
• Feedback: If you press Send, your feedback message, optional email address, app version, build number, platform, and language are sent to Runner Lock's server and stored so the operator can review and respond.
• Purchases: Apple processes App Store payments. Runner Lock uses RevenueCat to validate purchases, manage Premium access, restore purchases, and analyze subscription performance. RevenueCat receives purchase history and an automatically generated anonymous App User ID.
• No ads or sale of data: Runner Lock does not sell personal information, show third-party advertising, or use Health, location, or Screen Time information for tracking or marketing.
