Google Sign-In is used only to identify the owner of a Trace.
No personal information is stored.
Email, display name, profile photo, and Google account information are never stored.
Only a Firebase UID is stored so that only you can edit your Trace.
Google account data is never accessed.
Your Trace belongs to you.
The site provides a place for readers to leave a Trace, but does not edit user content.
Users are responsible for the content they leave.
The operator may remove content only when it violates the law, contains spam, or violates the Site Policy.
This is not a social network.
It is a quiet literary space where readers leave a single Trace.
World Memory stores only: Firebase UID, MIAV ID, auth type, location, message, and timestamps. Temporary (anonymous) traces also carry an expiry time.
