Privacy Policy
- Your habits, scans, sleep and streaks are stored on your phone only. We have no account system and no server that receives them.
- We do not sell your data, show ads, or use analytics or tracking tools.
- Apple Health and Screen Time data never leave your device and are never shared.
- Subscriptions are handled by Apple or Google, with RevenueCat keeping track of whether you've paid.
1. Who we are
BrainMaxx is published by Hemalayas, an independent developer (“we”, “us”). For any privacy question or request, email hemalkanjee03@gmail.com.
2. Data stored on your device
To work, the app stores the following in your phone's local storage. It is not uploaded to us.
- The habits you log (gains and drains), streaks, and clean-timer start dates.
- Your daily brain scan: self-ratings of mood, energy and clarity, reaction-test times and digit-span results.
- Onboarding answers, the name you give your brain, supplements you list, reminders you create and app settings.
- Sleep nights you log manually or that the app reads from Apple Health.
Deleting the app, or using You → Reset everything, permanently erases this data. Because we never receive it, we cannot recover it for you.
3. Apple Health (HealthKit)
If you choose to connect Apple Health, BrainMaxx reads sleep analysis, heart-rate variability and resting heart rate to chart your sleep. It does not write anything to Apple Health.
- Health data is processed on your device only and is not sent to us or any third party.
- It is never used for advertising, marketing or data mining, and is never sold.
- It is not stored in iCloud by us.
You can turn access off at any time in the iOS Settings app under Health → Data Access & Devices.
4. Screen Time (Focus shield)
If you use the Focus shield, iOS lets you choose apps to block. Apple gives BrainMaxx only opaque tokens for your selection: we cannot see which apps you chose or how you use them. Blocking schedules run on your device through Apple's Screen Time system. Nothing is sent to us. You can revoke access in iOS Settings → Screen Time.
5. Notifications
Reminders are scheduled locally on your phone. We do not use push notifications or a notification server.
6. Purchases and subscriptions
Payments are processed by Apple (App Store) or Google (Google Play); we never see your card details. We use RevenueCat to check whether your subscription is active. RevenueCat receives an anonymous app user ID, your purchase and subscription history, and basic device information such as the app version, operating system and country, under its own privacy policy. We do not link this to your name or email.
7. What we do not do
- No advertising, ad networks or ad identifiers.
- No third-party analytics, session recording or tracking across apps or websites.
- No selling or renting of personal data.
8. Legal bases (EEA, UK and similar laws)
Where data protection laws such as the GDPR apply, we rely on: performance of a contract to provide the app and your subscription; your consent for Apple Health, Screen Time and notifications, which you can withdraw at any time in iOS Settings; and our legitimate interest in preventing fraud with purchases.
9. Your rights
Depending on where you live (for example under the GDPR, UK GDPR, California CCPA/CPRA, Brazil's LGPD, South Africa's POPIA or Canada's PIPEDA), you may have the right to access, correct, delete or port your personal data, object to or restrict processing, and complain to your local data protection authority. Because your app data lives only on your device, you can view and delete it yourself in the app. For subscription records held by RevenueCat, email us and we will help you exercise your rights.
10. Children
BrainMaxx is not directed to children under 13 (or under 16 where local law requires) and we do not knowingly collect their data. If you believe a child has used the app, contact us.
11. Health disclaimer
BrainMaxx is a wellness and habit tool. Its scores are self-measurements for personal tracking, not medical tests, and nothing in the app is medical advice. See the Terms of Use.
12. International users
Your app data stays on your device. Subscription data processed by RevenueCat may be stored in the United States or other countries, with safeguards described in RevenueCat's policy.
13. Changes
If we change how data is handled, we will update this page and its effective date, and point out material changes in the app.
