REACNAR is built to collect as little as possible. We don't run third-party advertising trackers and we never sell data.
Guest mode
You can train without an account. In guest mode, every session — reaction times, mode, device latency profile — is stored locally on your device only. Nothing is uploaded. Clearing the app's storage permanently removes that history.
Leaderboard submission is optional
Submitting a result to the global leaderboard is an explicit per-session action. Until you tap submit, no result leaves your device. Submitted results carry only your chosen username, country, mode, reaction time, and an anti-cheat signature.
Email handling
If you create an account, we store your email solely for sign-in and one optional product email per major release. We never share it. We never sell it. There is no third-party marketing pipeline.
What we store, when you have an account
- Account email and chosen username
- Reaction results and session metadata you choose to sync
- Device model, OS version, and input latency profile (for accurate timing)
Deletion
You can permanently delete your account and every associated record from inside the app at any time. The request is irreversible and is honored within 14 days.
