Yes—but only in specific areas. Webull’s privacy controls can limit non-essential website cookies, selected device permissions, access to a mobile advertising identifier, and certain marketing-partner sharing. They do not switch off all data collection: information needed to provide, secure, and administer an account, as well as information Webull must retain, may still be processed.
What Webull says it collects
Webull Financial LLC’s U.S. financial privacy notice, last updated March 24, 2022, describes information users provide, data collected automatically, and information obtained from other sources. Examples include identity, contact and financial details; profile and interaction information; transaction activity; device identifiers, IP address, browser and network details; geolocation; and cookie or similar tracking data. The notice also describes information from service providers, partners, connected services, analytics providers, and public sources. Read Webull’s financial privacy notice.
Webull says analytics and advertising services may collect information about activity on its services and other websites over time, including pages viewed, time spent, links clicked, and conversion information. The settings below affect particular sources or uses of data; they are not a blanket opt-out from information needed for account and service operations.
Which settings can reduce collection or sharing?
| Control | Where it applies | What it can limit | Important limit or trade-off |

| Marketing-partner sharing request | Webull account/privacy request | Sharing with marketing partners for marketing across sites and apps | Does not end all sharing or third-party processing. |
| Access, correction, or deletion request | Account services or a request to Webull | Access to, review of, or changes to certain account information; deletion requests are subject to limits | Legal retention requirements and Webull’s retention practices may mean some records remain. |
1. Choose non-essential website cookies
Webull’s Cookie Policy, effective October 21, 2025, says that on a first visit to its website users can accept or reject non-essential cookies. The policy separates cookies into essential, performance and analytics, functional, and marketing and advertising categories. Review the banner when it appears and make a choice appropriate to your preferences. The policy covers Webull.com and online services; it should not be treated as a control for every tracker in the native mobile app. Read Webull’s Cookie Policy.
You can also block or delete cookies through browser settings, though Webull warns that doing so may affect functionality, including how quickly you can sign in. Its financial privacy notice says cookie opt-out preferences may need to be repeated when you change devices or browsers.

2. Review phone permissions
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. Open your phone’s operating-system settings, find Webull’s app permissions, and turn off access you do not want it to have. The exact labels vary by operating system and version, so use the current device settings rather than assuming a particular in-app menu path. Webull’s notice describes these permissions.
3. Limit mobile ad tracking
Webull says a device setting to limit ad tracking can prevent it from seeing the mobile advertising ID or IDFA. This narrows access to that identifier; it does not mean advertising partners receive no information at all. Webull’s notice says other personal information may still be shared with advertising partners.

For account deletion, the path given in Webull’s financial privacy notice is Settings → Account & Security → Delete Account. The notice also says users may request deletion by contacting Webull. Deletion is subject to normal retention practices, and records Webull is legally required to keep may remain. Public posts or information retained by search engines or third parties may also persist.
What does not work as a privacy opt-out?
Webull’s U.S. financial privacy notice says it does not currently respond to browser Do Not Track signals. Turning on that browser signal alone therefore does not stop Webull or its third-party services from collecting data under the practices described in that notice. See Webull’s statement on Do Not Track.

Why settings cannot stop all collection
Cookie preferences, device permissions, and advertising-ID controls act on distinct data sources or uses. They do not eliminate information needed to provide or secure an account, such as identity and financial information, transaction activity, or data used for compliance. Webull also says legal obligations can permit or require continued processing and record retention.
These disclosures have a defined scope: the financial privacy notice is from Webull Financial LLC and concerns U.S. financial-service information. Webull notes that some non-public personal information collected to provide financial services is governed by federal privacy laws rather than the California Consumer Privacy Act. The notice should not be read as a complete description of every Webull affiliate, international service, or app version.
