What data we store

Cosmic Dashboard stores one piece of data in your browser localStorage: your birth date, if you choose to enter it in the Human level. This is entirely optional. The key used is "cosmic-birth-date". No account or login is required.

Where data is stored

Your birth date is stored exclusively in your browser localStorage. It never leaves your device and is never transmitted to any server. Cosmic Dashboard has no backend database, no user accounts, and no analytics that collect personal information.

Timezone detection

The Earth level reads your browser's current timezone using the standard Web API Intl.DateTimeFormat().resolvedOptions().timeZone. This is a read-only operation, your timezone preference is not stored anywhere and is not transmitted.

Third-party services

Cosmic Dashboard is hosted on Vercel. Vercel may collect standard server logs (IP address, browser type, request timestamps) as part of normal web hosting operations. These are governed by Vercel's privacy policy, not this one.

How to delete your data

To remove your birth date from localStorage, open your browser developer tools (F12), go to Application > Local Storage > your domain, and delete the "cosmic-birth-date" entry. Alternatively, clearing your browser site data will remove it.
