GuardKit

GuardKit is a privacy-first iOS utility designed to help you understand when your device may have been moved or interacted with while you were away. GuardKit works by running user-initiated Guard Sessions that analyze motion signals such as acceleration, orientation changes, and handling-like movement patterns. If you choose to enable it, GuardKit can also monitor nearby audio activity levels to provide additional context. All analysis is performed on-device. Key features: • Motion-based activity indicators during active Guard Sessions • Optional audio activity level detection (no audio recording) • Clear, chronological timelines of detected events • Local-first data storage — your data stays on your device • Full user control over permissions and features Privacy by design: GuardKit does not record or store audio, does not transmit data to external servers, does not identify people, and does not track users across apps or devices. Motion and audio activity analysis occurs only when you explicitly start a Guard Session and enable optional features. Important notes: GuardKit provides informational indicators only. Detected activity may occur for many benign reasons, and results are probabilistic. GuardKit is not a security system, alarm system, or surveillance tool. Premium access: GuardKit offers a free 3-day trial with full access to premium features. After the trial, premium access is available via a one-time purchase (Lifetime Unlock). No subscriptions are required. Learn more at https://www.guardkitapp.com
