Privacy Policy for ZenFast

Effective Date: August 5, 2026

Welcome to ZenFast ("we", "our", or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, and safeguard your information when you use our mobile application.

1. Information We Collect

ZenFast is designed with an offline-first and privacy-first approach:

• Local Data: All your fasting timers, biological stage records, hydration logs, and history are stored locally on your device using encrypted local databases.
• No Personal Identifiers: We do not require account creation, login, or collection of personally identifiable information (PII) such as your name, email address, or phone number.

2. How We Use Your Information

Since all data remains stored locally on your device:

• Your data is used solely to provide core app functionality (tracking your fasts, calculating biological stages, and monitoring water intake).
• We do not transmit your health or personal logs to any external servers.

3. Data Security

We implement robust security measures to protect your local data against unauthorized access, alteration, or disclosure. Because your data lives on your device, you maintain full control and ownership.

4. Third-Party Services

ZenFast does not integrate third-party analytics trackers, advertising networks, or data brokers. Your wellness journey remains entirely private between you and your device.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
