Does itogai store the content of my emails or private messages?

Email is read as metadata only, permanently: who you write to, when, and how often. itogai never reads or stores an email body. For another source you consent to and turn content signals on for, the content is read once in memory to derive relationship signals and then discarded, and no message text, media, backup, password, or key is ever stored. Content signals are off by default, source by source.
