Privacy, by staying local.

Syllabus Practice Box has no account system, advertising, analytics, or remote server. Your imported materials and anonymous activity progress are stored in this browser’s IndexedDB on this device.

What is stored

Imported package content, answers, completion states, your theme choice, and the app shell needed for offline use. The app does not ask for a learner name, email address, or school.

What leaves this device

Nothing through the app. If you choose “Export backup,” your browser saves a JSON file where you direct it. You control any later sharing of that file.

Removing data

Remove an individual package from its topic page, clear this site’s storage in browser settings, or uninstall the Android app. Removing a package also removes its local answers and progress.

Device security

No student identity records are collected, so there is no identity record to encrypt. Device-level encryption and a screen lock are still recommended, especially where answers are sensitive.
