Privacy

We collect the minimum needed to run a training product, and we don't sell it. Ever.

What we store

• Account data: email, display name, optional age bracket (used only for norms), preferred language, time zone.
• Learning data: your answers, timings, scores, plan progress, and streaks — this is the product.
• Anonymous guest results, linked to a random cookie until you create an account and claim them.

What we don't do

• No third-party trackers, no ad pixels, no analytics beacons. Our only cookies are for sign-in, your guest test, and preferences.
• No selling or sharing of personal data.

Your controls

From Settings you can export all your data as JSON, or delete your account. Deletion removes your personal data immediately; anonymized answer statistics (which contain nothing about you) remain in item-calibration aggregates.

Email

We send account emails (confirmation, password reset). Product updates are opt-in only.
