"To help improve the relevance of these ads, we provide certain info about you to third parties, including advertising partners, or allow them to collect such data from our services (such as via cookies, SDKs, or similar technologies). Some of our advertising partners enable us to transform your email address, advertising identifiers or phone number into an identifier that can't be used to identify you personally and then use that unique identifier to either exclude you from our marketing campaigns, or to target our ads at an audience that is similar to you."
Tinder shares personal data including account data, profile data, usage data, and technical data with advertising partners, and acknowledges activities that may constitute 'sales' or 'sharing' under US privacy laws, offering an opt-out rather than opt-in.
