Our promise · Every 0n1 game
Every game we make is free of ads, tracking, and in-app nagging — by design, not as a perk. You are the player, never the product.
Some 0n1 games are solitary and fully offline — LineBy has no account and no server; there's nothing to sign into. Others may need more plumbing: real-time multiplayer, a shared puzzle library, progress that follows you across devices. When a game genuinely needs an account or a backend to work, we build it to ask for the least it can, keep it optional wherever we can, and use it only to run the game — never to profile you, track you, or sell what we learn. That's the line we don't cross.
Simple: you pay once, fairly — and that's the entire arrangement. LineBy is free to play, with a new puzzle every day; a single one-time $0.99 unlock opens the full library, and that's the end of it — no subscription, no second charge, ever. That one optional dollar is the whole business model: no ads to sell, no data to monetize, nothing to forget to cancel. Future 0n1 games share the same values — free or a fair one-time price, no ads, and nothing that monetizes your attention or your data.
Where a game can run entirely on your device, it does — LineBy works with no signal and no account, and anything it syncs travels through your own iCloud, device to device, not a server we run. Where a game needs a backend to work, we keep only what the game needs and hold it to the same privacy-first standard. The specifics live in each game's privacy policy: LineBy and Duels.
Most "free" games aren't free — you pay with your attention and your data, and the game is quietly built to take more of both. We think that's a bad trade. A game should respect your time, end when you want it to, and leave nothing running in the background. Games should earn your attention, not harvest it.
LineBy is on the App Store now; Duels is coming soon to iOS & Apple Watch. Questions? Email [email protected].
