Your Privacy Rights (EEA, UK, and California)
Depending on where you live, you may have the right to access, correct, update, or request deletion of your personal information, to object to or restrict certain processing, and to data portability. If you are in the European Economic Area or the United Kingdom, our processing is based on your consent (for advertising) and on our legitimate interest in operating and improving the Application. If you are a California resident, you may request that we do not sell or share your personal information; we do not sell your information for money, but sharing advertising identifiers with advertising partners for personalized ads may be considered a sale or share under the CCPA.
