Essential & Functional Storage

We use browser localStorage to remember your UI color theme preference and maintain your bookmarked tools locally. No private files or passwords are stored in cookies.

Authentication Session State

If you choose to sign in via Google OAuth or Firebase Authentication, session tokens are securely maintained to preserve your active login state.
