Lilerno keeps private study data separate from public learning resources.

Account and study data

• Google sign-in may provide an account identifier, name, email address, and profile image.
• Signed-in study can store private decks, cards, enrollments, review state, attempts, and session activity.
• Public learning resources do not expose private account or study routes to search crawlers.

Cookies, analytics, and local settings

• An account session cookie keeps a signed-in learner connected to the service.
• Google Analytics is configured with denied storage by default and follows the learner's analytics consent choice.
• The browser stores consent and theme preferences locally so those choices can be restored.

Current limits

Do not submit sensitive personal information through unofficial channels. A fuller privacy notice, verified contact path, retention schedule, and account-data request process must be published before Lilerno expands personal-data collection beyond the current product needs.
