Cookie Policy
What cookies are
Cookies are small text files a website leaves on your device. Local storage works much the same way. They let a site remember simple things — which region you are in, which pairs you starred in the app preview — and help us understand, in aggregate, how the site is used so we can keep it fast and legible.
Where this applies
This website is the official companion site for the Coinbase Inc mobile app. It does not provide web-based trading; deposits, withdrawals, custody and account functionality are not available. Because there is no sign-in anywhere on this site or in the app preview, we set no authentication cookies and hold no session tied to a person.
How Coinbase Inc uses cookies and local storage
We keep our use deliberately light. It falls into three categories:
Essential
- Remember your language and timezone
- Hold safety-critical display settings in place
- Protect the support form against abuse
Functional
- Store the pairs you star in the app preview, in your own browser
- Remember the last screen and timeframe you viewed in the preview
- Keep your cookie choices so we do not ask again on every visit
Analytics & performance
- Show us, in aggregate, which parts of the site and preview are used
- Measure load times and market-data freshness
- Surface error patterns so we can smooth them out
Favorites stay on your device
Favorites you star in the app preview are written to your browser's local storage under a Coinbase Inc key. They never leave your device, they are not sent to us, and they are not linked to any identifier. Clearing your browser data removes them permanently.
Cookies from our partners
Occasionally the Service loads resources from trusted third parties:
- Public market data endpoints — so the preview can show live prices
- Web font providers — for the typefaces used across the site
- Edge and security networks — caching and protection against attacks
Managing your preferences
You are always in control. Through your browser you can:
- Block all cookies and local storage
- Block only third-party cookies
- Delete anything already stored
- Have everything clear automatically when you close the browser
What we may collect
- Your IP address and approximate region
- Browser type, version and operating system
- Pages viewed and time spent
- The page that referred you
- Your saved display preferences
How long things stay
- Session cookies: cleared the moment you close the browser
- Persistent cookies: kept for up to 12 months
- Preference cookies: held for 12 months
- Preview favorites: kept in local storage until you clear them
If you switch cookies off
You are free to disable cookies and local storage, though a little convenience goes with them: starred favorites will not return between visits, and the preview will always open on its default screen. Live prices will still load.
Compliance
Our approach is designed to align with GDPR (EU), CCPA (California) and other privacy frameworks that apply to you. We revisit this policy as those rules evolve.
Updates and contact
We may refresh this policy from time to time; any material change will be reflected in the date above. Questions are welcome at [email protected] or through the support channel on any page.
