Brainfuel is built to respect your privacy. The short version: we do not collect, store, or transmit your personal data. There are no accounts, and everything the app records stays on your device.
None that leaves your device. Brainfuel has no user accounts and no servers that store your data. Your settings, quiz history, and on-device activity stats are saved only in local storage on your iPhone.
Brainfuel uses Apple's Screen Time (Family Controls) to block the apps you choose. The apps you select and your usage of them are managed by iOS and are never shared with us. Apple does not make this information available to Brainfuel, and we do not collect it.
Subscriptions are processed entirely by Apple through the App Store. We never see or store your payment details. Apple handles billing, renewals, and refunds under its own privacy policy.
If you allow notifications, Brainfuel uses them only on your device (for example, the prompt to take a quiz when an app is blocked). We do not use push servers and do not track whether you open them.
Brainfuel includes no third-party analytics, advertising, or tracking SDKs. We do not profile you and do not sell data, because we do not collect any.
Brainfuel is not directed at children under 13 and does not knowingly collect any information from them.
If this policy changes, we will update this page and the date above.
