Do I need an account?
No. The playable modes keep progress and settings locally. Production online features are not required to understand, finish, or replay a run.
Does an ad interrupt the timer?
No. Active play is ad-free. Production advertising remains disabled until account approval, consent, policy, and placement review are complete.
What is stored for playtesting?
Optional analytics default off and stay on this device. If a tester opts in, they can export typed events and coded questionnaire choices as JSON or CSV. The form has no name, email, recording, or free-text field.
What accessibility options exist?
Keyboard controls, visible focus, screen-reader status text, reduced motion, high contrast/color assistance, mute, and separate effects and music volume controls are included.
