Terms of Service

These terms govern your use of CatherineSien. By creating an account or using the service, you agree to them.

Your account

You must provide accurate information and keep your Google account secure. You are responsible for activity carried out through your CatherineSien account and for ensuring you have permission to add or share trip information about other people.

Using CatherineSien

CatherineSien is for personal travel planning and shared expense tracking. Do not misuse the service, interfere with its operation, attempt unauthorized access, or use it in violation of applicable law.

Your content

You retain ownership of the information and content you add. You give CatherineSien permission to store, process, and display that content only as needed to operate the service and share it with the people you choose.

Travel and financial information

CatherineSien helps organize plans and expenses; it does not provide travel, legal, financial, or insurance advice. Confirm bookings, prices, documents, entry requirements, and settlement details directly with the relevant providers and people involved.

Availability

We may change, suspend, or discontinue features as the product develops. The service is provided on an “as is” and “as available” basis to the extent permitted by law.

Termination

You may stop using CatherineSien at any time. We may suspend or terminate access when these terms are violated or to protect the service and its users.
