Privacy Policy
Brainmaxxed is a brain-training app for phones. This policy explains in plain English what the app does with your information. "We" and "us" mean the developer of Brainmaxxed. It covers the app only — Apple's App Store, your Apple ID and your payment details are covered by Apple's own privacy policy.
The short version
You can use Brainmaxxed without an account. Your game history and settings stay on your phone, with no cloud copy and nothing to sync. Usage analytics and crash reports are two switches that are off unless you turn them on, and you can turn either off again whenever you like. Purchases are handled by Apple, with RevenueCat confirming what you bought. There are no ads, no tracking across other apps or websites, and your data is not sold.
What stays on your device
- Round history. For each round the app stores which game you played, your score, your accuracy, your median reaction time and when you played. It keeps the most recent 1,000 rounds and discards the oldest.
- Settings. Your game switches, haptics, daily reminder, privacy switches, and the date you first opened the app, which starts the 7-day trial clock.
- Where it lives. In the app's own private storage on the device. There is no account, no server copy, no sync between devices, and no backup we can reach.
What leaves your device, and only when you allow it
- Usage analytics (PostHog), only while the analytics switch is on. The app sends event names such as that a round finished, a session finished, the paywall was viewed, a purchase started or completed, and a setting changed. The properties are specific to each event: which game, the score, accuracy and median reaction time, your position in the session, your access level, and whether a switch is on. The analytics service also records routine technical details such as app version, device type and operating system version, and gives the app a random identifier for the installation. Events are not tied to your name, your email address or an account, because the app never asks for one.
- Crash reports (Sentry), only while the crash reports switch is on and a crash-reporting service is configured. If the app crashes or hits an unexpected error, it can send a technical report: what went wrong, where in the code, the app version, the device model and the operating system version. Before a report leaves the app, request bodies, cookies, login headers and URL query strings are stripped and console logs are dropped, so what is sent is diagnostics rather than your game history. No crash reports are sent while this switch is off.
- Purchases (Apple and RevenueCat). Apple takes the payment and holds your payment details; we never see your card number, and neither does the app. RevenueCat receives Apple's receipt for the purchase and an anonymous purchase identifier it generates, which lets the app confirm that you unlocked everything and restore the unlock on another device. RevenueCat does not receive your name or email address from us.
- The daily reminder. It is a notification the app schedules on your phone. It needs no server, and turning it off cancels it.
The app does not link your analytics events to your purchase record.
What we do not collect
- No name, email address, phone number, postal address or date of birth. If you email us, we see your email address and whatever you write.
- No contacts, photos, camera, microphone or precise location.
- No Apple Health data — the app does not read or write it.
- No advertising identifier, no tracking permission prompt, and no tracking of what you do in other apps or on websites.
- No ads, and no selling or renting of personal data to anyone.
- No third-party analytics or social plugins beyond the two switches described above.
Your choices
- Both switches appear once, after your first round. They start off, and nothing is sent unless you turn one on. Continuing without turning them on is a valid choice.
- Change either one at any time in Settings → Privacy. Turning analytics off tells PostHog to stop; turning crash reports off stops crash reporting immediately.
- Turning a switch off stops collection from that moment. Events already sent stay with the provider until they are deleted; email us if you want that.
- The daily reminder has its own switch in Settings, and turning it off cancels the scheduled notification.
Deleting your data
- On the device. Settings → Your data → Delete all my data erases your round history from the device straight away. It cannot be undone. Your preference switches and the trial date are kept, because they are settings rather than history. Deleting the app removes everything it stored on the device, including those settings.
- Analytics and crash data. Email us and we will delete what we hold. These records are not tied to a name or an email address, so we may need your approximate dates and device model to locate them.
- Support emails. We keep them only while we deal with your request, then delete them.
How long we keep things
- On your device: until you delete your history, delete the app, or the storage is cleared.
- Usage analytics: only as long as we need it to understand how the app is used, then deleted.
- Crash reports: while the fault they describe is being fixed, then cleared.
- Support emails: until the request is closed.
Children
Brainmaxxed is for people aged 13 and over and is not directed at children under 13. We do not knowingly collect information from a child under 13. If you believe a child under 13 has used the app, email us: anything stored on the device can be removed with Delete all my data or by deleting the app, and we will delete anything we hold.
Who else is involved
- Apple — runs the App Store, takes the payment and issues receipts.
- RevenueCat — confirms the one-time purchase and restores it.
- PostHog — processes usage analytics when the switch is on; this project's data is hosted in the United States.
- Sentry — processes crash reports when the switch is on and a crash-reporting service is configured.
Each of them handles data only to provide that service, under its own terms and privacy policy. Some of them process data outside your country, including in the United States. We do not sell your data or share it for advertising, and we do not hand it to anyone else unless the law requires it.
Security
Data on your device is protected by the phone's own protections, such as the device passcode and file encryption. Reports sent to PostHog and Sentry travel over HTTPS. Because there is no account, there is no password of yours for us to lose. No system is perfectly secure, and no app can promise absolute security.
Your rights
Depending on where you live you may have the right to ask for a copy of your data, to have it corrected or deleted, to restrict or object to how it is used, to receive it in a portable form, to withdraw consent, and to complain to a data protection authority. Most of what the app stores is already in your hands: delete your history in Settings and delete the app to remove the rest. For anything we hold, email us and we will help. Withdrawing consent is the same two switches. We do not sell personal data, so there is nothing to opt out of on that front.
Changes to this policy
If the app changes, this policy changes with it. We update the date at the top whenever we do, and the version published on this page is the one that applies. If a change is significant, it will be explained here before it takes effect.
