Terms of Use

Effective date: March 11, 2026

These Terms of Use ("Terms") govern your use of Circade ("the app"), a sunrise alarm clock for iOS. By using the app, you agree to these Terms.

1. Description of Service

Circade calculates your local sunrise time using your device's GPS location and sets an alarm accordingly. The app requires location and notification permissions to function properly.

2. Subscriptions and Payments

• Circade offers a free tier with limited features and a paid subscription ("Circade Pro") with additional features.
• Subscriptions are billed through your Apple ID account via the App Store.
• A free trial period may be offered. If you do not cancel before the trial ends, your subscription will automatically renew and you will be charged.
• Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period.
• You can manage or cancel your subscription in your device's Settings > Apple ID > Subscriptions.
• Refunds are handled by Apple per their App Store refund policy.

3. Alarm Disclaimer

Circade is not a safety-critical alarm system. Due to iOS platform limitations:

• The alarm works best when the app remains open (not force-closed) overnight.
• If the app is force-closed, a fallback notification will be sent, but iOS limits notification sounds to approximately 30 seconds.
• The app cannot override Do Not Disturb or Silent Mode.
• Sunrise times depend on a third-party API and your device's GPS accuracy.

We do our best to ensure reliable alarms, but we are not responsible for missed alarms or any consequences thereof. Do not rely solely on Circade for time-critical wake-ups.

4. Acceptable Use

You agree to use the app for its intended purpose as a personal alarm clock. You may not reverse-engineer, decompile, or attempt to extract the source code of the app.

5. Intellectual Property

All content, design, and code in Circade are owned by the developer. Classical music tracks included in the app are royalty-free or properly licensed.

6. Disclaimer of Warranties

The app is provided "as is" without warranties of any kind, express or implied. We do not guarantee that the app will be error-free, uninterrupted, or that sunrise times will be perfectly accurate.

7. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the app, including but not limited to missed alarms.

8. Changes to Terms

We may update these Terms from time to time. The "Effective date" above will be revised. Continued use of the app constitutes acceptance of the updated Terms.

9. Governing Law

These Terms are governed by the laws of the United States. Any disputes shall be resolved in accordance with applicable law.
