About 0n1 Studios

Independent · mobile & desktop

0n1 Studios is an independent studio crafting privacy-first games for mobile and desktop. We build games we want to play — carefully made, atmosphere-first, and respectful of the people who play them.

The name

0n1 is written with a zero — zero, n, one — and pronounced "oh-nee". Said out loud, we're Oni Studios; either spelling will find us.

What we believe

Games should earn your attention, not harvest it. Every 0n1 title is built privacy-first: no ads, no sign-ups, no tracking, and no manipulative monetization. Many of our games are free to play; where a game charges, it's a fair one-time price — and what you unlock is yours. It works offline, and anything we sync (like your progress) stays in your own iCloud. That principle shapes the whole studio. Read why we work this way →
