1. Choose non-essential website cookies
Webull’s Cookie Policy separates cookies into essential, performance and analytics, functional, and marketing and advertising categories. On a first visit to Webull’s website, its banner allows visitors to accept or reject non-essential cookies. The policy also describes browser controls for blocking or deleting cookies and lists third-party advertising opt-out tools. These are website controls; Webull’s policy does not establish that the banner controls every tracker in the native app. See the Webull Cookie Policy for its categories and options.
Blocking or deleting cookies can affect how the website works, including how quickly a user can sign in. Webull’s financial notice also cautions that opt-out preferences may need to be repeated after changing browsers or devices.
2. Review permissions on your phone
Webull says users can disconnect its mobile app from certain stored device information through the device’s settings, giving contacts and the photo gallery as examples. Review the Webull app’s permissions in your phone’s operating-system settings and consider whether each permission is needed for features you use. This limits access to the selected device data; it does not erase account, transaction, or other information Webull already holds.

3. Limit access to the mobile advertising identifier
Webull says users can set a mobile device to limit ad tracking. In that case, Webull says it cannot see the advertising ID or IDFA. The same notice cautions that other personal information may still be shared with advertising partners, so this is a narrow identifier control rather than a general advertising-data opt-out.
4. Ask Webull to limit specified marketing-partner sharing
Webull says users can contact it to limit sharing with marketing partners for marketing across sites and apps. If this is disabled, Webull says it will no longer share personal information with those partners for those purposes. That statement is limited to the specified marketing use; it does not mean Webull stops sharing information needed to provide services or stops all third-party processing.

What these controls do not turn off
Cookies, app permissions, and advertising identifiers concern particular sources or uses of information. They are not a single switch for Webull’s collection. Webull’s notice also describes identity, contact, and financial information, transactions, service activity, device and network data, and information obtained from other sources. Some information may be needed to provide or secure an account, meet legal obligations, or administer the service.
Browser Do Not Track is not a substitute for the controls above. In its financial privacy notice, Webull says it does not currently respond to browser Do Not Track signals or other mechanisms intended to express choices about tracking across third-party sites or services over time. Turning on that browser setting alone therefore does not tell Webull to stop collection.

Access, correction, and deletion requests

The detailed financial notice qualifies those options: withdrawing consent does not affect processing permitted or required by law, and deletion follows normal retention practices. Records that Webull must keep under applicable law may remain after a deletion request. Public posts or information held by search engines or other third parties may also persist.
For account deletion, Webull’s notice gives this app path: Settings → Account & Security → Delete Account. It also says users may request deletion by contacting Webull. The path is the one documented in that notice; app labels or screens may differ by version.

How jurisdiction affects the answer
The cited financial privacy notice concerns Webull Financial LLC and U.S. financial-account information. Webull says some non-public personal information collected to provide financial services is governed by federal privacy laws rather than the California Consumer Privacy Act (CCPA). California privacy rights should therefore not be assumed to apply identically to every financial-account data category. The applicable rights and retention rules depend on the information and service involved.
