Carve Rush is a skill game. It can be played without registration, without a user account and without providing any personal details. We only process data required to run the game, operate the leaderboard and improve the game technically.
We do not sell data, we do not build profiles, and we do not use your data for third-party personalised advertising.
Most of your progress stays on your device only and is never transmitted to us:
This data is removed when you uninstall the app or clear its data in your system settings.
To make the leaderboard and feedback work, the app signs your device in anonymously. This creates a random identifier (UID) that does not identify you as a person. We never collect e-mail addresses, names, phone numbers or social media accounts.
When a run ends, a result record is stored:
| Data | Purpose |
|---|---|
| score, distance, top speed, world, board, riding mode, reason the run ended | leaderboard, game balancing |
| the rider name you chose | display in the leaderboard (publicly visible) |
| device model (e.g. “Redmi 2312DRA50G”), app version, control scheme, frames per second, run duration, technical performance metrics | troubleshooting and performance optimisation across devices |
| anonymous identifier (UID) | attributing your personal best, avoiding duplicate entries |
If you use the feedback function (🐛) in the menu, your message text, device model, app version and the anonymous identifier are transmitted. This data is readable by us only and is used solely to improve the game. You decide whether and what to write — please do not enter personal data there. You can also reach us any time at developer@ncn.at.
When content and updates are retrieved over the internet, the services used process technically necessary data such as IP address, time of access and device/app information. This is required to deliver content and keep the service stable.
