Privacy
Shift Master at playshiftmaster.app can be played without an account. This page covers the email login and the one-time Shift Pass.
Scores
Floors, stars, sound, and best scores stay in this browser’s local storage. They are not uploaded with a purchase.
If you ask for a sign-in link, Clerk sends that email and keeps the account. The address is used to recognize the account and to attach a Shift Pass. Shift Master does not run its own mailbox.
Payment
Stripe charges $6.99 once for a Shift Pass. Card details are entered on Stripe’s checkout page, not on this site. Stripe sends a paid receipt to the server, and the account is marked with a Shift Pass. There is no subscription and no stored card in Shift Master.
