Privacy
Your checklist ticks are stored only in your browser (localStorage). We use one first-party cookie to keep your account, which holds nothing but whether you bought the Tracker Pass.
Payments are handled by Stripe; we never see your card. The email you pay with is used only to send you a sign-in link if you open the tracker on another device.
We count visits with Umami, which does not use cookies or track you across sites. Feedback you send through the form goes to us; leave an email only if you want a reply.
