BrainFit is a brain-training mini-games app for older adults. This page explains exactly what data we touch, where it goes, and your choices. Short version: no account, no ads, no cross-app tracking, no data sales — your settings and brain-age result stay on your device.
BrainFit (脑力时光) is an iOS app distributed through the Apple App Store. In this policy, "we", "our", and "us" refer to the operator of BrainFit; "you" means anyone who installs or uses the app. Contact: feedback@globalpixelstudio.com.
No account is required and we do not ask for your name, email, phone number, or contacts. During onboarding you may enter your age and pick a text size; this is used on-device to compute your for-fun brain-age estimate and to size the interface. We do not receive this as identifiable data.
To understand which features are used and to keep the app stable, we collect anonymized usage analytics and crash diagnostics through Google Firebase. This may include: app screens viewed, games started and completed, button taps within the funnel, app version, device model, OS version, language, coarse region, and crash logs.
Your settings (language, text size), your brain-age result, and your training streak are stored locally on your device using iOS UserDefaults. This stays on your device and is removed if you delete the app.
Purchases of BrainFit Pro are processed entirely by Apple through your Apple ID. We never see or store your payment card or full Apple ID. We receive only the anonymized entitlement status (whether a subscription is active) needed to unlock features. Apple's handling of payments is governed by Apple's privacy policy.
Anonymized analytics are retained by Firebase for a limited period per Google's defaults and then aggregated or deleted. On-device data persists until you delete the app.
Depending on where you live (e.g., GDPR in the EU/UK, CCPA in California), you may have rights to access, correct, or delete personal data, and to object to certain processing. Because we collect only anonymized analytics and store personal preferences locally, the simplest way to remove all on-device data is to delete the app. For other requests, email feedback@globalpixelstudio.com. We do not sell personal information.
BrainFit is designed for adults (with older adults in mind) and is not directed to children under 13 (or the equivalent age in your region). We do not knowingly collect data from children.
Our service providers (e.g., Google, Apple) may process data on servers outside your country. Where required, appropriate safeguards apply to such transfers.
We rely on Apple's platform protections and reputable providers. No method of transmission or storage is 100% secure, but we work to protect your information using industry-standard practices.
We may update this policy; material changes will be reflected by updating the date above. Continued use after changes means you accept the updated policy.
