Privacy notice

This notice describes data handling for the Japan 2026 Trip Dashboard and its Google Calendar connection.

Data accessed and its purpose

ChatGPT sign-in supplies an account identifier and basic profile information to control dashboard access. When its owner connects Google, the application verifies the Google account's email address and requests permission to create secondary calendars and manage events on calendars created by this application.

Calendar event titles, times, locations, descriptions, reminders, and event identifiers are used to display plans and save requested event changes. The connection does not request Gmail, Google Drive, Contacts, administrator access, or access to pre-existing calendars.

Storage and access

The dashboard stores its calendar identifier, event information, checklist state, and other travel records in private application storage. Google refresh credentials are encrypted in server storage; the encryption key and client credential are protected server secrets. Google credentials are not included in browser code or offline downloads.

Calendar change logs store identifiers, action, actor, time, and version information rather than event descriptions. Hosting and identity providers process data needed to operate the service and may retain technical security and access logs.

Authorized dashboard users can access its records. People separately granted access to the dedicated calendar can access it in Google Calendar according to the permissions assigned there. The public information pages do not expose dashboard records.

Use and disclosure

Google data is used to operate the calendar and trip-planning features requested by the owner. It is not sold, used for advertising, or supplied to general-purpose AI model training. Service providers process data as needed for hosting, identity, and Google Calendar operations.

The application's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements where applicable.

Offline copies

When a user downloads the trip for offline access, plans and selected documents are stored on that device. These copies may remain until the user clears the download or the site's local storage. Device copies should be protected using the device's access controls.

Disconnecting and deleting data

Disconnect Google Calendar in the dashboard to remove the stored connection and request revocation. Access can also be revoked through Google Account connections. Disconnecting does not delete the Google calendar, its events, or previously downloaded device copies.

Calendar events and calendar-sharing permissions can be removed directly in Google Calendar. To request removal of application-stored records, contact support below. Provider backups may retain historical encrypted records according to the provider's retention practices; revoking a Google grant prevents further use of that grant.
