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.
Copy-ready boundary brief
Bundle the data boundary, same-set practice links, and source page for a parent, teacher, or support helper.

Use: copy this for a learner, parent, teacher, or support helper who needs to continue practice without treating legal pages as progress sync or official school records.
