Privacy

This build does not use advertising cookies, accounts, or a feedback database.

What is stored

• The selected view, date and language are written into the page URL so a link can be shared.
• No personal data is requested by the 3D viewer.

Optional error and performance reporting

If the operator configures VITE_SENTRY_DSN, unexpected JavaScript errors and sampled Web Vitals are sent to Sentry. This build disables Sentry session replay and does not send default personally identifying information. If no DSN is configured, no error/performance data leaves the browser.

Feedback form

The optional “反馈 / Feedback” link opens a Tally form. Responses are processed by Tally under its own privacy terms; the form does not require an account, and the contact field is optional. Do not submit sensitive personal information.

Hosting logs

The static host may keep standard request logs (IP address, user agent, requested URL) for security and operations. Those logs are controlled by the host, not by the 3D application.

External services

By default all textures, fonts and transcode assets are served from the same origin and no external runtime request is made. If you add analytics, weather, maps, music, or a feedback form, update this page and add the relevant consent.
