What are cookies?

Cookies are small text files stored on your device when you visit a website. Their purpose is to enhance your browsing experience by remembering certain preferences and settings.

What cookies do we use?

We only use essential technical cookies for purposes strictly necessary for the site's functionality. We do not use third-party or advertising cookies.

• —__vdpl: This cookie is used by our hosting provider (Vercel) for skew protection. It ensures you fetch assets from the correct deployment version if a new update is released while you are browsing. It does not track you.
• —h3: This is our secure session cookie. It stores the OAuth access token when you connect your Atmosphere account. It is essential for maintaining your authenticated session.

Local storage

In addition to session cookies, we use your browser's Local Storage to save your display preferences. This allows us to remember the theme (light/dark) and some other settings you have selected, so you don't have to reconfigure them on each visit.

This information is purely functional, stored only on your device, and contains no personal data nor is it used to track you. We use it exclusively to improve your experience on our website.

Managing cookies

You can configure your browser to accept, reject, or delete cookies according to your preferences. However, please note that rejecting essential cookies may prevent full access to the application.

Analytics

We use Vercel Web Analytics to understand how visitors use our website. This helps us improve the user experience and identify issues.

Vercel Analytics is designed with privacy in mind:

• —It does not use cookies
• —It does not collect personal identifiers
• —It does not track users across websites
• —All data is aggregated and anonymised

The only information collected includes: page URLs, referrer, country/region, device type, browser, and operating system. This data cannot be used to identify individual users.

Authenticated users

When you connect your Atmosphere account to npmx, we store your OAuth access token in a secure, HTTP-only session cookie. This token is used solely to authenticate requests on your behalf.

We do not store your credentials, and we do not access any data beyond what is necessary to provide the features you use. You can disconnect your account at any time from the settings page.

Data retention

Session cookies are automatically deleted when you close your browser or after a period of inactivity. Local storage preferences remain on your device until you clear your browser data. Analytics data is retained in aggregate form and cannot be linked to individual users.

Your rights

You have the right to:

• —Access information about what data we collect
• —Clear your local storage and cookies at any time
• —Disconnect your authenticated session
• —Request information about our data practices

Since we do not collect personal data, there is typically no personal information to delete or export.
