How CORVUS uses cookies and browser storage. Last updated: October 7, 2026.

CORVUS does not set any cookies. We use your browser's local storage only to remember display preferences you choose. Nothing is used for advertising or cross-site tracking, so there is no cookie banner to accept.

1. Cookies and local storage

Cookies are small files a website stores in your browser and that are sent back to the server with each request. Local storage is a similar browser feature, but the data stays in your browser and is not sent with requests. CORVUS uses local storage, not cookies.

2. What CORVUS stores

All of these are strictly functional: they only remember choices you make so the site looks and behaves the way you left it.

KeyPagePurpose
corvus-themeAll pagesLight or dark theme
corvus.timezoneDashboardLocal time or UTC display
corvus.prefsDashboardLayout and display preferences
Indicator and favourites keysDashboardChart indicators you added and symbols you starred
Signal source keyDashboardWhich signal feed you selected

These entries never expire on their own; they stay until you clear them.

3. Third-party services

Pages load fonts, market data and a charting library from third parties (listed in our Privacy Policy). CORVUS does not ask these services to set cookies, and we do not embed advertising, social-media or analytics trackers.

4. How to control it

You can delete CORVUS preferences at any time by clearing site data for this website in your browser settings (often under Privacy → Cookies and site data). The site keeps working without them; it will simply fall back to the defaults, such as following your system's light or dark setting.

5. Changes

If we ever introduce cookies or non-essential storage, we will update this policy and, where the law requires it, ask for your consent first.
