Time zone
Every time on the site (chart axes and crosshairs, heatmaps, order-book and trade timestamps, news, pattern dates, funding times) is shown in this zone. Auto follows your device; Exchange uses each market's own zone (UTC for crypto). The same picker opens from the clock in the header and under every chart.
Categories
- Strictly necessary: your consent choice. Always on, because without it we couldn't remember a “reject”.
- Preferences: theme, time zone, watchlists, starred pairs, chart indicators and drawings, price alerts and dismissed headlines. These are only created when you use the feature.
- Cache: short-lived copies of public market data (1 minute to 1 hour).
- Advertising (optional): Google AdSense and its partners, only after you accept. See the privacy policy for details and opt-out links.

Frequently asked questions
What happens if I reject non-essential cookies?
The site works exactly the same, except that no advertising code is loaded. Your theme, watchlists and other settings keep working because they are stored on your device, not in cookies.
Why does the site still store data after I reject?
Your consent choice and the settings you set yourself are strictly necessary to provide what you asked for. The market-data cache only holds public prices so that free APIs are not called over and over.
Will clearing site data delete my watchlists?
Yes. “Clear everything” removes your watchlists, alerts, chart drawings and settings from this browser. They are not stored anywhere else, so they cannot be restored.
Do my choices follow me to other devices?
No. There are no accounts, so each browser and device keeps its own settings and its own consent choice.
