Cookies and Browser/App Storage

This page explains how Weatherius uses cookies and browser/app storage in the current app version.

Cookies

The current app code does not intentionally set first-party cookies directly.

Vercel Web Analytics (if enabled)

If Vercel Web Analytics is enabled for this project, it is designed as a privacy-focused measurement tool and not as a third-party advertising-cookie tracker.

Per Vercel documentation, Web Analytics is cookie-free and uses request-derived hashing with visitor-session data discarded after 24 hours.

localStorage

The app uses localStorage for core functionality, including:

• Theme preference (light/dark).
• Forecast skill/blend diagnostic state (weather.skillBlend.v1).

sessionStorage

The app uses sessionStorage for session-level functionality, including:

• Active selected location for session restore.
• Last known weather snapshot for resilience/fallback display.

Third-Party Services

Third-party services or infrastructure providers may use their own cookies or similar technologies under their own policies.

These services can include map providers, weather data providers, CDNs, and hosting infrastructure.
