Overview

Your privacy is our priority. ByteFast is designed to be private by default. We do not collect, store, or sell your personal fasting data. All your information stays under your control.

1. Data Collection

ByteFast does not collect any personal information. All fasting sessions, presets, and activity data are stored locally on your device and within your personal, private iCloud storage (via CloudKit).

2. Data Storage & Sync

Your data is synchronized across your devices using Apple's CloudKit service. This data is stored in your private iCloud database, which is only accessible by you using your Apple ID. Apple encrypts this data in transit and at rest.

3. Third-Party Services

ByteFast does not share your data with any third-party services. We do not display advertisements and do not include social media tracking pixels.

4. Health & Medical Disclaimer

ByteFast is a tool for tracking fasting windows and is not a medical device. The information provided is for educational purposes only and should not be considered medical advice. Always consult with a healthcare professional before starting a new fasting regimen, especially if you have underlying health conditions.
