NULLRUN
Clear the floor. Take a gate. Go deeper.
The game
NULLRUN is a sci-fi roguelite shooter built for one hand and short sessions. Drag to move, stand still to fire. Clear the floor, then walk through one of the gates that open — and the gate you pick builds the next floor.
Twelve enemy types, five boss tiers, twenty-eight upgrade cards, and gear that lasts between runs. Every run has a seed: share it and send someone the exact same sixty floors.
Four gates, four kinds of floor
- ■ SquareAn open platform — sometimes a long deck, sometimes a T or a Y.
- ▲ TriangleA maze. Walls block movement, shots and line of sight.
- ⬟ PentagonThe Void — a ribbon of walkway over nothing, with gaps your bolts cross and your legs do not.
- ● CircleA reward run, offered only after a boss.
Where to play
Privacy policy
NULLRUN (“the Game”) is published by NULLRUN (“we”). This policy explains what data the Game handles.
Data the Game stores on your device
The Game saves your progress (materials, upgrades, equipment, best floor, settings, purchase status) and a short log of gameplay events — for example “run started”, “floor 12 reached” — locally on your device. This data does not leave your device unless one of the services below is enabled in the version you installed. Uninstalling the Game deletes it.
Services that may process data
Google AdMob (advertising). The Game shows optional rewarded ads, which you choose to watch, and occasional interstitial ads. AdMob may collect your advertising ID, IP address, device and app information, and coarse location derived from IP, to serve and measure ads. You can reset or delete your advertising ID and opt out of personalised ads in your device’s Google settings. Purchasing “Remove Ads” or the “Starter Bundle” disables interstitial ads. Google’s privacy policy
Google Play Billing via RevenueCat (purchases). In-app purchases are processed by Google Play. RevenueCat receives a purchase token and an anonymous app user ID to verify and restore purchases. We do not receive your payment details. RevenueCat’s privacy policy
Firebase Analytics (analytics). If enabled, anonymous gameplay events — session start, floors reached, deaths, upgrades chosen, ads viewed, purchases — and device information are sent to Firebase to understand how the Game is played and improve it. This data is not used to identify you personally. Firebase’s privacy policy
Data we do not collect
The Game has no accounts, no login, no chat, no contacts, no camera, no microphone and no precise location. We do not sell personal data.
Children
The Game is not directed at children under 13, and we do not knowingly collect personal data from children. If you believe a child has provided personal data through a third-party service in the Game, contact us and we will help remove it.
Your rights
Depending on where you live — for example under the GDPR in the EEA and UK, or the CCPA in California — you may have rights to access, delete or restrict processing of personal data. For data held by the services above, use their own controls (Google Ads Settings; your device’s advertising ID). For anything else, contact us.
Data deletion
Uninstalling the Game deletes all locally stored data. To request deletion of any data held by the services above on our behalf, email the address below.
