PRIVACY

Last updated: 2026-08-15

WHAT WE STORE

Your sign-in identity (handled by our authentication provider), your game progress (runs, answers, spaced-repetition scheduling, streaks, achievements), your settings, and your 3-letter arcade tag. That's the product.

WHAT WE DON'T

No advertising trackers, no third-party analytics scripts, no selling or sharing of data. Cookies exist solely to keep you signed in. The anonymous demo stores nothing about you at all — we count only that a demo was started or finished.

PAYMENTS

Cert Cartridge payments are handled entirely by our payment processor. Your card number never touches our servers — we don't store it, and we couldn't read it if we wanted to. The only thing the game knows is whether your account currently holds the Cartridge.

REMINDER EMAILS

With reminders on (the default), we email you from hello@flashkube.dev on days you have cards due or a streak at risk — never on a quiet day, never for marketing. Those emails go out through a transactional email service that sees your address and the message, nothing else. Every one carries a one-click unsubscribe, and the same switch lives on your settings page.

WHO SEES WHAT

Teammates see your arcade tag and scores on the leaderboard — never your name or email. Aggregated, non-identifying usage numbers guide development.

YOUR DATA, YOUR CALL

Want your account and every trace of it deleted? Email hello@flashkube.dev and it's done. The same address answers any privacy or billing question.
