Terms of Use

1. Acceptance of Terms

By downloading, installing, or using Kaizen Timer ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the App.

2. Description of Service

Kaizen Timer is an interval timer application for iOS designed for workout and training use. The App allows users to create custom interval presets with configurable work, rest, warmup, and cooldown phases, multiple rounds, haptic and audio cues, and optional Apple Health integration for logging completed workouts.

3. Health & Fitness Disclaimer

Kaizen Timer is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or health condition.

The App provides interval timing and optional calorie estimates based on MET (Metabolic Equivalent of Task) values. These calorie estimates are approximations and should not be relied upon for medical, dietary, or clinical purposes.

Always consult with a qualified healthcare provider before beginning any exercise program. You are solely responsible for your own physical safety during workouts.

4. User Responsibilities

You agree to:

• Use the App only for its intended purpose as a workout interval timer
• Exercise at a level appropriate for your fitness and health
• Keep your device and the App secure
• Not use the App for any unlawful purpose
• Not attempt to reverse engineer, modify, or distribute the App

5. Apple Health Integration

Kaizen Timer can optionally write workout data (duration, estimated calories burned) to Apple Health. This feature requires your explicit permission and can be enabled or disabled at any time in the App's settings.

Health data written to Apple Health is governed by Apple's privacy policies. Kaizen Timer does not read from or access any existing Health data — it only writes completed workout records when you have opted in.

6. Intellectual Property

The App, including its content, features, design, and functionality, is owned by Kaizen Timer and is protected by copyright, trademark, and other intellectual property laws. You may not copy, modify, distribute, or create derivative works based on the App.

7. Privacy

Your privacy is important to us. Please review our Privacy Policy to understand how we handle your information. By using the App, you consent to the practices described in the Privacy Policy.

8. Data and Backups

All your data — presets, settings, and workout history — is stored locally on your device. We are not responsible for any loss of data due to device malfunction, app deletion, or other circumstances. We recommend regularly backing up your device through iCloud or Finder.

9. Limitation of Liability

To the maximum extent permitted by law, Kaizen Timer and its developers shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to:

• Loss of data or settings
• Personal injury or health consequences arising from exercise
• Inaccurate calorie estimates or workout data
• Any other damages arising from the use of the App

10. Disclaimer of Warranties

The App is provided "as is" and "as available" without warranties of any kind, either express or implied. We do not warrant that the App will be uninterrupted, error-free, or completely secure.

11. Changes to Terms

We may update these Terms of Use from time to time. Continued use of the App after changes constitutes acceptance of the new terms. We encourage you to review these terms periodically.

12. Termination

We reserve the right to terminate or suspend access to the App at any time, without notice, for conduct that we believe violates these Terms or is harmful to other users or us.

13. Governing Law

These Terms shall be governed by and construed in accordance with applicable laws, without regard to conflict of law principles.
