Privacy

Drill scores stay on your device. We store an email address only when you ask for the prep plan or when a payment needs a receipt and an access link.

What the browser keeps

Finished sessions are saved in local storage under a key this site owns. That history is how the percentile is calculated. It never leaves the browser as a score report. An affiliate code from a ?via= link is saved the same way so checkout can attribute the sale.

Email and payment

The prep-plan form sends your address to our server and, when the database is connected, into a private table. You can unsubscribe with the link in that email. One-click unsubscribe is supported. Purchase receipts are sent through the same email provider and include the access link. Card details are handled by Stripe, not typed into this site.

Analytics and errors

A cookieless analytics script may load from this same domain, proxying to our own analytics host, so the counts are page views and the events named on the buttons: a call to action, a plan request, checkout started, a purchase, a drill started, a drill finished. Addresses we recognise as internal tests are excluded from those events. Error reports go to Sentry, tagged for this project, when a DSN is configured. If it is not configured, nothing is sent.

Asking for a copy or a deletion

Write to [email protected] from the same address. Say whether you want the plan emails stopped, the row deleted, or a copy of what we hold. Stopping the emails is the unsubscribe link. Deletion is a manual step on our side.
