We store your spaced repetition (SRS) card progress (scheduling intervals, due dates, review
history), study statistics (streak, total reviews, accuracy), and any custom vocabulary decks
you create. This data is linked to your account and synced across your devices.

We store a session token along with your IP address and browser/device type (user agent
string) to keep you signed in. Sessions expire after 30 days.

We use PostHog to collect page view counts, feature interaction events, and JavaScript error
reports. PostHog records sessions for approximately 20% of visits to help us diagnose bugs.
PostHog data is stored on servers in the United States.

stays on your device. It is only uploaded to our servers when you explicitly sync.
