Advertising. To measure and improve our advertising, we may share a hashed (irreversibly encoded) version of identifiers such as your email address with advertising platforms (e.g. Google and Meta) to measure conversions and build similar-audience models. We do not share the underlying plain-text identifiers, and we never sell your data.
