LeanFast ("the App") is developed by VertexLab Solutions. We are committed to protecting your privacy. This policy explains how we handle your data.
We do not collect, store, or transmit any personal data. All data you enter into LeanFast (weight, fasting sessions, food logs, progress photos, water intake) is stored exclusively on your device using local storage.
All app data is stored locally on your device using Apple's SwiftData framework. No data is sent to any server. We do not have access to your data.
LeanFast may optionally integrate with Apple HealthKit to read and write weight data. This data is governed by Apple's HealthKit privacy policies and is never shared with third parties. HealthKit access is entirely optional and requires your explicit permission.
LeanFast does not use any analytics SDKs, tracking pixels, or advertising frameworks. We do not track your behavior or usage patterns.
LeanFast uses Apple's StoreKit 2 for in-app purchases. Purchase transactions are handled entirely by Apple and are subject to Apple's privacy policy.
All AI features (fasting coach, weight prediction, pattern analysis) run entirely on your device. No data is sent to external AI services for core features.
LeanFast is not intended for children under 17. We do not knowingly collect data from children.
LeanFast does not provide medical advice. The app is intended for general wellness purposes only. Consult a healthcare professional before starting any fasting program.
We may update this policy from time to time. Changes will be posted on this page with an updated date.
