Privacy Policy

CatherineSien is a travel-planning app. This policy explains what information we collect, how we use it, and the choices available to you.

Information we collect

When you sign in with Google, we receive and store your Google account identifier, name, email address, and profile photo. We use the OpenID Connect, email, and profile scopes only. CatherineSien does not request access to Gmail, Google Drive, Google Calendar, or any other Google account data.

We also store information you choose to add to CatherineSien, such as your travel preferences, trips, itineraries, shared expenses, and memories.

How we use information

We use your information to authenticate your account, personalize the service, create and manage your travel plans, and operate shared-trip features. We do not sell your personal information or use Google user data for advertising.

Sharing and service providers

We share information only with service providers that help us host and operate CatherineSien, when you choose to share a trip with others, or when required by law. We do not transfer Google user data to third parties except as needed to provide the service, comply with law, or with your consent.

Retention and security

We keep account and travel information while your account remains active, or as needed to provide the service and meet legal obligations. We use reasonable technical and organizational safeguards, but no online service can guarantee absolute security.

Your choices

You can revoke CatherineSien’s access from your Google Account permissions. To request access to, correction of, or deletion of your CatherineSien account information, contact us at [email protected].

Changes to this policy

We may update this policy as CatherineSien evolves. We will post the updated version here and revise the effective date when material changes are made.
