How Lang Study collects, uses, stores, and protects personal information

2026/06/28

Learning-data boundary

Lang Study separates browser-local practice records, account data, uploaded files, and provider-processed services so learners, families, and teachers know what each feature stores.

Browser-local progress

Free practice may keep completed characters, missed strokes, review items, worksheet settings, and returned-paper source metadata in this browser.

Account and files

Account identity, uploaded practice files, payment records, and email support are separate from local progress unless a feature explicitly syncs or imports them.

Provider boundary

Payment, email, storage, analytics, OAuth, stroke-order, and future AI providers process only the parts needed for their configured feature.

Check your data boundary

Back up progress

Review and export browser-local progress before changing devices or clearing storage.

Account files

Manage uploaded worksheet scans, reference images, and classroom files separately from local progress.

Account security

Review sign-in, password, and OAuth boundaries before treating account identity as practice sync.

Same-set continuation paths

Each link preserves the starter HSK1 set so the legal boundary can return to practice, print, handoff, or account follow-up without losing scope.
