1. Summary
NeuroCamp is a collection of offline brain-training games developed by Haoxian Yan. It has no account system, no analytics, no telemetry, no advertising, and no server component of any kind. It does not transmit anything about you anywhere.
2. Data collection
None. No personal information, no usage analytics, no crash telemetry, no device identifiers, no advertising identifiers. The games do not ask who you are, and there is no server that could receive an answer.
3. Data stored on your device
The app keeps a small amount of state in local storage inside its own sandbox:
- Your best scores and recent results, so a game can show whether you improved.
- Your theme preference (dark or light).
- Game settings such as difficulty or grid size.
This never leaves the device, is not readable by other apps, and is deleted when you uninstall NeuroCamp or clear its storage.
4. Device permissions
NeuroCamp requests no special permissions. It does not access your camera, microphone, location, contacts, or shared storage. Its Android package includes the standard internet permission that the app framework adds, but the games never use it; the links in About (the credits and this policy) open in your browser. The sound-based games (Chord Scout, Interval Birds, Rhythm Sync) synthesise audio on the device with the Web Audio API rather than playing recorded files, so the app needs no media access and downloads no sound assets. Nothing is ever recorded.
5. Advertising
NeuroCamp contains no advertising. There is no ad SDK bundled in the app, no banner, and no rewarded-video button. If that ever changes, this section will be rewritten before the change ships, not after.
6. Third-party services
There are none. No analytics SDKs, no crash reporters, no social logins, no ad networks. The app is built with Capacitor and its core Android plugins only; everything it needs is bundled at build time and nothing is fetched from a CDN at runtime.
7. Children
The games are simple and suitable for general audiences. Because the app collects no data from anyone, it collects no data from children either.
8. Changes to this policy
If the app's handling of your data changes, this policy will be updated along with it, and the date at the top will change.
