Privacy Policy

The static Practice Lab stores User IDs, a password hash, and attempt history in your browser (localStorage / sessionStorage). Those values are not sent to a Grok13 server by this codebase.

Do not use a real high-value password

The hash is a simple browser-side function. It is not a bank-grade credential store.

Hosting logs

If you deploy the files on a host or CDN, that provider may log IP addresses and user agents under its policy.

Fonts

Pages may load fonts from Google Fonts under Google’s policies.

Children

Not directed to children under 16.

Requests

Because data lives on your device, clearing site data is the deletion mechanism for the static build.
