🌙 Cycle Calendar — Terms of Service

Last updated: May 2026 · Version 1.0

Short version: Cycle Calendar is a free personal wellness tool. Use it at your own risk. It is not a medical product. We provide no guarantees and accept no liability for how you use the information it provides.

1. Acceptance of terms

By installing or using the Cycle Calendar Chrome extension ("the Extension"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, please uninstall the Extension and do not use it.

2. Description of service

Cycle Calendar is a free Chrome browser extension that helps users visualise their menstrual cycle phases as events in their personal Google Calendar. The Extension calculates approximate phase dates based on information entered by the user and creates calendar events accordingly.

3. Medical disclaimer

Important: Cycle Calendar is NOT a medical device and does NOT provide medical advice of any kind.

• The phase dates and descriptions provided are estimates based on average cycle patterns. They are intended for general personal awareness only.
• The information provided by the Extension should not be used to make medical decisions, diagnose any health condition, or as a method of contraception or fertility treatment.
• Always consult a qualified and licensed healthcare professional for any medical concerns, questions, or decisions.
• The developer accepts no responsibility for any health outcomes arising from use of or reliance on information provided by the Extension.

4. User responsibilities

By using the Extension, you agree that:

• You are at least 13 years of age
• You will use the Extension for lawful, personal purposes only
• You understand and accept that cycle phase calculations are estimates, not medical facts
• You take full responsibility for how you use the information provided
• You will not attempt to reverse engineer, copy, or redistribute the Extension without permission

5. Google account and data

The Extension requires access to your Google Calendar account to function. By granting this access you agree to Google's own Terms of Service and Privacy Policy. We are not responsible for Google's handling of your data.

The Extension only creates and manages events within a calendar named "My Cycle" or "Мій цикл". It does not access, read, or modify any other calendar data in your account.

6. Intellectual property

The Extension, including its code, design, text, and icons, is the intellectual property of the developer. You may not copy, modify, distribute, or create derivative works without explicit written permission.

7. Disclaimer of warranties

The Extension is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to:

• Accuracy or completeness of cycle phase calculations
• Uninterrupted or error-free operation
• Fitness for any particular purpose
• Compatibility with all versions of Chrome or Google Calendar

8. Limitation of liability

To the maximum extent permitted by applicable law, the developer shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the Extension, including but not limited to health decisions made based on information provided by the Extension.

9. Availability and changes

We reserve the right to modify, suspend, or discontinue the Extension at any time without notice. We may also update these Terms at any time — the "Last updated" date at the top of this page will reflect any changes. Continued use of the Extension after changes to the Terms constitutes acceptance of the updated Terms.

10. Governing law

These Terms are governed by and construed in accordance with the laws of Ukraine, without regard to conflict of law principles.
