Terms of Service

Last updated: June 29, 2026

These Terms of Service (“Terms”) govern your access to and use of the cirrca iOS application and related services (collectively, the “Service”) operated by the developer of cirrca (“we”, “us”, or “our”). Please read these Terms carefully before using the Service.

Important: cirrca is a wellness and self-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Do not use cirrca as a substitute for professional medical care. If you have a health emergency, contact emergency services immediately.

1. Acceptance of terms

By creating an account, downloading, or using the Service, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

2. Eligibility

You must be at least 13 years old (or the minimum age required in your jurisdiction) to use the Service. If you are under the age of majority where you live, you may use the Service only with permission from a parent or legal guardian who accepts these Terms on your behalf.

3. The Service

cirrca provides features that may include:

Manual sleep logging (bedtime and wake time)
Optional microphone-based sleep tracking while a session is active
Optional wake alarms during tracking sessions
Energy check-ins and optional caffeine tracking
Insights based on patterns in your logged data
Optional integration with Apple Health and Apple Watch data
Account-based sync across devices

We may add, change, or remove features at any time. We do not guarantee that the Service will be available at all times, error-free, or suitable for every user or device.

4. Account registration and security

You are responsible for maintaining the confidentiality of your account credentials.
You agree to provide accurate information and keep it up to date.
You are responsible for activity that occurs under your account.
Notify us promptly at support@cirrca.app if you suspect unauthorized access.

5. Acceptable use

You agree not to:

Use the Service for any unlawful purpose
Attempt to gain unauthorized access to the Service, other accounts, or our systems
Reverse engineer, decompile, or attempt to extract source code except where permitted by law
Interfere with or disrupt the Service or its security features
Use the Service to harass, abuse, or harm others
Upload malware or automated scripts that impose an unreasonable load on our infrastructure

6. Microphone, notifications, and device permissions

Some features require device permissions (for example, microphone, notifications, or Apple Health). You can revoke permissions at any time in iOS Settings, though related features may stop working.

If you use microphone-based tracking, you are responsible for using the feature lawfully and with respect for the privacy of others in your environment. Do not record others without their consent where required by law.

7. Health and wellness disclaimer

Sleep stage estimates, energy insights, and other outputs in cirrca are provided for general wellness and informational purposes only. They may be inaccurate and can vary by device, environment, and individual. Always consult a qualified healthcare professional for medical questions, sleep disorders, or treatment decisions.

8. Your content and data

You retain ownership of the information you submit to the Service (“User Content”). You grant us a limited license to host, process, and display User Content solely to operate and improve the Service as described in our Privacy Policy.

You represent that you have the right to submit your User Content and that doing so does not violate any third-party rights or applicable law.

9. Third-party services

The Service may integrate with third-party services such as Sign in with Apple, Google Sign-In, Apple Health, and cloud infrastructure providers. Your use of those services is subject to their terms and policies. We are not responsible for third-party services.

10. Subscription and fees

The Service may be offered free of charge at launch. If we introduce paid features or subscriptions in the future, we will present applicable pricing and payment terms before you are charged. Apple’s App Store terms govern in-app purchases processed through Apple.

11. Termination

You may stop using the Service at any time. To delete your account, contact support@cirrca.app from the email address linked to your account (or use in-app account deletion when available in Settings).

We may suspend or terminate your access if you violate these Terms, if required by law, or if we discontinue the Service. Upon termination, your right to use the Service ends, subject to the Privacy Policy regarding data retention and deletion.

12. Intellectual property

The Service, including its design, software, trademarks, and content (excluding User Content), is owned by us or our licensors and is protected by intellectual property laws. These Terms do not grant you any right to use our branding except as necessary to use the Service.

13. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR AFFILIATES, OFFICERS, EMPLOYEES, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF THE SERVICE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) USD $50.

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

15. Indemnification

You agree to indemnify and hold us harmless from claims, damages, losses, and expenses (including reasonable legal fees) arising from your use of the Service, your User Content, or your violation of these Terms or applicable law, except to the extent caused by our negligence or willful misconduct.

16. Governing law and disputes

These Terms are governed by the laws of the jurisdiction in which the developer operates, without regard to conflict-of-law principles, except where mandatory consumer protection laws in your country require otherwise.

If you are a consumer in the European Union or United Kingdom, you may also have the right to bring claims in your country of residence. Before filing a formal dispute, please contact us at support@cirrca.app so we can try to resolve the issue.

17. Changes to these Terms

We may update these Terms from time to time. We will post the updated version on this page and update the “Last updated” date. If changes are material, we may provide additional notice in the app or by email. Continued use of the Service after changes become effective constitutes acceptance of the revised Terms.
