Privacy Policy — VialLogic

Last updated: November 7, 2026

VialLogic is designed as an on-device mathematical and personal record-keeping utility for reconstitution unit math you enter yourself.

What we store

• Reconstitution inputs, vial inventory, dose logs, biometric journal entries, and preferences are stored locally on your device (SwiftData / UserDefaults).
• Optional Face ID / device passcode lock protects access on your device only.
• Optional Apple Health weight read uses HealthKit only if you tap Sync and grant permission. We do not write Health data.

What we do not do

• We do not operate a VialLogic cloud account for your protocols.
• We do not sell personal health data.
• We do not use vial or dose history for advertising profiles.
• App Store purchases are processed by Apple; we never see your full payment card details.

Ads & analytics

• Free users may see an in-app sponsor preview (or a future rewarded placement) to unlock a one-time Pro action credit. No banner ads appear in the vault.
• App Tracking Transparency tracking is not enabled (NSPrivacyTracking = false).
• No third-party analytics or crash SDK is shipped in the current build.

Notifications

Local notifications for dose windows / expiry are scheduled on-device and can be disabled per vial or in Settings.
