🍪 Cookies
We use analytics cookies (Google Analytics) to understand how you use the site. You can accept or reject them — the site works fully either way.
Get a browser notification the moment a cryptocurrency crosses your target price. No account, no email, no tracking — alerts are stored in your browser and checked while this tab is open.
When you add an alert, it's saved to your browser's local storage. As long as you keep this page open in a tab, we check the live prices every 60 seconds and fire a browser notification when any threshold is crossed. Alerts survive reloads and tab close — they just don't run while the tab is closed.
Tip:install CryptoWatcher24 as a PWA (desktop “Install app” icon in Chrome/Edge) to keep alerts running in a persistent app window instead of a browser tab.
Your alert list never leaves your device. We don't have accounts, we don't have a database. You're fetching prices from our public API, and everything else happens in your browser.
