Playing without an account

Your card, your streak and what you write are saved in your own browser, and nowhere else.
If you play a round, the Board gets your ring name, a random device id, your scores and the time. You can switch that off in your locker.
The Board and your leagues keep those until you press Start over in your locker. That takes them off.
A league shows your ring name and scores to the people in it. A challenge link carries them to whoever opens it.
Plays are counted without names. If the page crashes, the error and your browser type are sent.
Feedback you send is kept with your ring name, the card number and the time.
To stop abuse, the server keeps your internet address for a day or two.

We keep your email address and whether your plan is on.
While you are signed in, we keep a copy of your card, streak, scores and what you wrote, so they follow you to another device.
If you sign in with Google, Google tells us your email address and that it is yours. We ask for nothing else.
If you sign in by email, the code is sent by Resend, our mail service.
A cookie keeps you signed in on that browser for 90 days. It is used for nothing else.
Delete your account from its page and we delete the email and the copy we hold.

Payments are taken by Stripe on Stripe’s own page. We never see your card.
Stripe keeps its own record of the payment and your email, as the law makes it. Deleting your Undo account does not delete that.

No ads. No selling or sharing your details for marketing. No tracking across other sites.

Accounts are for people aged 13 and over. Buying is for people aged 18 and over.
