Privacy policy

1. Information we collect

We store only the Google account identity and authentication records required by Supabase Auth to create and secure your account. We do not create a profile or collect your name, organization, profession, country, website, or health information.

2. Your session results

Drill settings, scores, response times, and saved drills stay in your own browser and are never uploaded. Clearing your site data removes them, and they do not follow you to another device.

3. Product usage events

So we can tell whether the drills are actually useful, we record a small event when a drill is started or completed, when a Pro feature is reached, and when a plan changes. Each event holds an event name, your account id, the drill and category, your plan, and the drill difficulty and session length.

We do not record page URLs, IP addresses, device fingerprints, or the content of anything you type. There is no third-party analytics service, no advertising network, and no tracking cookie — the data stays in our own Supabase database.

4. Plan and payment data

We store when your free trial started and ends, and — if you subscribe — a subscription status, renewal dates, and a Stripe customer reference. Card details are handled entirely by Stripe and never reach this application.

5. Contact & data removal

You can request account deletion through the project administrator. Deleting the Supabase Auth user removes the stored login identity, its authentication records, your usage events, and your trial and subscription records. Session results in your browser can be cleared from the Progress page at any time.
