What this workspace saves

Parent email and a securely hashed password, sign-in sessions, parent permission records, learner nicknames and hashed PINs, saved character styles and buddy nicknames, submitted answers, requested hints, assessment results, daily visit dates, earned achievements, and a points ledger. Essential cookies and temporary security records protect sign-in and prevent abuse. Parent sign-in records include IP and browser information. We do not use advertising or analytics cookies. Do not use a child’s full name as a nickname.

How the information is used

To sign you in, provide learning feedback, save progress, and show reports to the learner’s parent. Answers are checked with deterministic rules. This release uses written coaching and worked examples; student answers are not sent to a generative AI provider.

Control your records

The parent workspace provides reports, a download of family learning records, PIN changes and permanent deletion of individual learners. In account settings, withdraw permission and delete all learners while keeping your parent login, or close the entire family account. Deleted learners cannot sign in and their sessions are revoked. Whole-family deletion requires the current parent password. No child is required to provide more information than is needed for these learning activities.

Parent permission comes first

US parents and legal guardians may create a learner profile, including for a child under 13, after completing the parent permission process. Children do not create email accounts or give permission themselves. Parents verify their email, declare they are an adult parent or legal guardian in the United States, receive a direct privacy notice, approve it and confirm a separate follow-up email. The service does not request a government ID. This email process is used for the service’s limited internal use of learning records; it is not a government identity check. Refusing permission prevents activation. Parents can withdraw permission at any time.

For account or privacy questions, see family support.

Authentication and learning records are stored in this application’s database. The hosting infrastructure uses OpenAI Sites and Cloudflare. This application does not include behavioral advertising, public student profiles, student messaging, photo uploads, or voice uploads. Resend receives parent email addresses and account links to deliver account and permission notices. Porkbun hosts the support mailbox and receives messages sent to support. These providers support the service’s operations. We do not sell children’s records or provide them to advertisers. Please do not send a child’s full name, photo or unnecessary personal information to support.

Retention and recovery

Active records support ongoing practice and parent reports. After 365 days without family activity, a retention check sends a notice and gives the parent 30 days to sign in or export records before account deletion. Signing in cancels the notice. Unverified accounts become eligible for deletion after 30 days; incomplete permission requests expire after 7 days. Expired sign-in and recovery records are cleared after one day.

Encrypted recovery copies are usable for 28 days. Older copies are refused by the recovery process and removed during the next retention check. Hashed deletion receipts are kept for 35 days so restoring an older copy cannot reactivate deleted records. Recovery excludes sign-in sessions and password-reset tokens. Recovery keys are held separately from the database.

Retention and backup checks are designed to run daily. The operator monitors successful completion and retries missed or failed runs. Account and learner deletion requests take effect immediately in the live application; routine expiry cleanup runs during successful maintenance checks. Provider-managed security logs and infrastructure recovery copies are governed by the relevant provider’s terms; their separate deletion schedules have not yet been independently verified.
