Learning without a personal profile
You can read the lessons and use the sign explorer without creating an account. The explorer does not require your name, email address or birth details. Its selected sign is a study choice and is not used to build a personal profile.
Site operation and measurement
Site measurement is limited to coarse aggregate page and outbound-link events. Tool inputs and user identity are not retained in those events. Hosting infrastructure may process ordinary request metadata to deliver and protect the site. Do not put personal information into a page URL.
External websites
Reference links open independently operated websites with their own privacy practices. We do not attach your birth details or tool selections to those links. Review a destination’s own policy before providing information there.
