A small amount of data.

Primer uses Google to sign you in. It stores your Google account ID, name, verified email, sign-in sessions, saved game progress, and any level feedback you choose to send. It does not request access to your mail, files, or contacts.

Progress and feedback are kept until the owner removes them. The owner can see account/progress summaries and all submitted level feedback with its author. Other learners cannot see your feedback. This preview has no advertising or analytics. A grown-up should manage the sign-in for a child.

For account or data removal, contact gabe@sibley.io. The hosted game stores data on the owner's personal Oracle Cloud server. Local development keeps its separate data on the development computer.
