We may share data with: (a) service providers who assist in operating the Platform under data processing agreements; (b) analytics providers (Google Analytics — see Google's privacy policy); (c) legal authorities when required by law or to protect our legal rights.
Depending on your jurisdiction, you may have rights to: access, correct, or delete your personal data; object to or restrict processing; data portability; withdraw consent at any time.
