Flux Control — Last updated July 2026
Flux Control is a power-grid puzzle game. This policy describes what data we collect, why, and how you can request deletion.
To understand how hard each level is, we also record, per level, how many switches you flipped before solving it. This is stored with your account, used only to improve level design, and deleted with your account.
We do not collect your name, email address, phone number, location, device identifiers, or any data for advertising or third-party analytics purposes. There are no third-party SDKs in the app.
Your data is used only to run the game: authenticate you, restore your progress across sessions, and calculate leaderboard rankings. It is not sold, shared with third parties, or used for any purpose outside the game.
Account and progress data is stored on our server at fluxcontrol.eu. Your authentication token is stored locally on your device.
Your account and all associated data are retained for as long as the service is running. To request deletion of your account and data, email felixvonsamson@gmail.com with the subject line "Flux Control account deletion" and your username. We will delete your account within 30 days.
The game is rated 4+ and is suitable for all ages. We do not knowingly collect data from children under 13 beyond what is described above (a username and gameplay progress), and we do not use that data for any purpose other than running the game.
If this policy changes materially, we will update the date at the top of this page. Continued use of the app after a change constitutes acceptance of the updated policy.
