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.

Contact support

Ask which workflow or provider boundary applies before sharing classroom details.

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.

Starter set: 口 二 一 人 三
Boundary: browser-local progress, returned-paper marks, copied handoffs, account files, and provider-processed services are separate unless a feature explicitly imports or syncs them.
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.
