Brain Groove is built to respect your privacy. We collect as little as possible, we don't sell your data, and we don't use advertising networks. This policy explains what we handle and why, in plain language.
The short version
- We don't require an account to play.
- We don't sell or rent your personal information to anyone.
- We don't use any advertising network.
- We keep one small progress record per player on our own server (your streak and play totals under an anonymous player ID), so reinstalling doesn't cost you your streak.
- We use privacy-minded analytics to improve the app, with your device's advertising identifier switched off.
- We advertise Brain Groove elsewhere, and we see which campaigns bring new players through the app stores' own measurement. That measurement does not use your advertising identifier, and we do not ask to track you.
- Your scores stay on your device unless you opt in to online leaderboards.
- Our website uses Google Analytics and Google Ads measurement. In the EU, the EEA, the UK and Switzerland it sets no cookies.
- If you start the free trial, redeem a code, or answer a campaign question, we also store your game-service player ID against that record, and for codes and campaign answers, your game-service nickname as a label. Not your name, email, or anything else.
Information we collect
Gameplay data on your device. Your scores, progress, settings, and which tutorials you've seen are stored locally on your device so the game works the way you left it.
Progress sync. So that reinstalling the app or switching devices doesn't cost you your streak, Brain Groove keeps one small record for you on our own server, created automatically the first time you open the app. It is identified by an anonymous player ID: your game-service player ID (such as Apple Game Center or Google Play Games) when your device has one, otherwise a random identifier your device generates for itself. Against that ID we keep a summary of your play (your streak, how much you've played and when), basic app and device facts (platform, app version, language, time zone, country, phone or tablet), your current in-app settings, and whether you've bought Brain Groove Pro. We use it to restore your streak and daily progress and to understand in aggregate how many people play and keep playing. It holds no per-game scores, no history of individual rounds, and nothing you type.
Leaderboards (optional). If you choose to use leaderboards, your platform's game service (such as Apple Game Center on iOS) handles your nickname and high scores under that provider's own privacy policy. You can turn this off in your device settings at any time.
Free trial. If you start the free Pro trial, we send your platform game-service identifier (such as your Apple Game Center player ID) to our own server and store it alongside the date your trial began. We use this only to run your trial and to stop the same person from repeatedly restarting it, for example after reinstalling the app. It is not linked to your name or email, is not shared or sold, and is not used for advertising.
Redeem codes and campaign answers. If you type a promo code into Settings, or answer a question on a campaign card in the app (for example, opting in to a contest), we send your game-service player ID, the code or answer, and the nickname your game service shows for you at that moment to our server. The player ID binds the code or answer to you so it can't be reused by someone else; the nickname is stored only as a readable label next to that record and is not used to look you up. Failed code attempts are logged against your player ID so that codes can't be guessed by brute force.
Campaign configuration. When the app checks which campaign cards to show, it sends our server your app version, platform, the campaign answers you've already given, whether you have Pro, whether you're signed in to a game service, and roughly how long ago you installed. No identifier is sent with this request.
Measuring our own ads. We run ads for Brain Groove on other platforms and want to know which campaigns bring new players. We do not use a mobile measurement partner or any other SDK dedicated to attribution. We rely on the app stores' own measurement, reported to us through the Google Analytics for Firebase SDK described below and our Google Ads account: Google Play's install referrer on Android, and Apple's privacy-preserving SKAdNetwork on iOS. Neither uses your advertising identifier, and Brain Groove does not show you the App Tracking Transparency prompt.
Anonymous diagnostics. With your permission, your device's operating system may share crash reports and basic, aggregated usage statistics that help us fix bugs. These are not tied to your identity.
Analytics. We use Google Analytics for Firebase to understand how the app is used in aggregate (for example, which games are opened and how often rounds are played) so we can improve it. This records app activity (such as screens viewed and rounds completed) together with a Google-generated app-instance identifier and general device and region information. We have turned off collection of your device's advertising identifier (Apple's IDFA and the Android Advertising ID), so this data cannot be used to follow you across other apps and websites. Our analytics property is linked to our own Google Ads account so we can see which of our campaigns bring players. Google processes this data as our service provider under Google's privacy policy.
What we do not collect
- We do not collect your name, email, phone number, or contacts.
- We do not track your precise location.
- We do not collect your device's advertising identifier (IDFA or Android Advertising ID). We've disabled it.
- We do not use any advertising network.
- We do not use a mobile measurement partner or any other SDK whose purpose is advertising attribution. What we learn about our own ads comes through the analytics described above and the app stores themselves; it tells us which campaigns worked and does not follow you across other companies' apps or websites.
How we use information
We use the limited data above only to run the game, save and restore your progress and streak, power optional leaderboards, run the free trial, codes and campaigns and protect them from repeat abuse, understand aggregate usage and retention, measure which of our own ads bring new players, and improve stability and difficulty tuning. We do not sell it.
Service providers and retention
Our server and this website run on Cloudflare, and the progress, trial, code and campaign records described above are stored there. Analytics and ad measurement are processed by Google. Each acts on our instructions and under its own privacy policy. Your progress record is kept for as long as you keep playing, and records for trials, codes and campaign answers are kept while the feature that uses them is live. Day-by-day activity is not kept beyond the most recent 32 days. You can ask us to delete your records at any time using the contact below.
Our website
braingroove.app uses Google Analytics to understand how visitors use the site, and the Google Ads tag to tell us when a visit that came from one of our ads leads to a tap on an App Store or Google Play button. Google receives the page you viewed, the page you came from, what you did on it (such as tapping a store button or finishing a demo), your browser and device type, and an approximate location that Google works out from your IP address.
In the European Union, the rest of the European Economic Area, the United Kingdom and Switzerland, these tags run without cookies: nothing is stored on your device, and Google receives only the visit itself, without any identifier that could link it to your other visits. The one exception is a visit that came from one of our Google ads: Google adds a click identifier to the link, and if you then tap a store button or finish a demo, our server keeps a record of that tap (the time, your device type and browser, the country, the referring page and the campaign) and sends that identifier back to Google Ads, with what you did and when, so Google can tell us which ads work (we do this in every country, not only these). Outside these countries, Google sets its own measurement cookies on braingroove.app, so that repeat visits are counted once and a store tap can be matched to the ad that led to it. We use this to measure our own pages and campaigns only. We do not use it for personalised advertising or remarketing, and we do not share it with any other advertiser. Google processes this data as our service provider under Google's privacy policy.
When you follow one of our short share links (for example, from a social profile) our redirector records the link used, the time, your device type, the country the request came from, the referring page, and your browser's user-agent string, so we can see which links people use. It does not store your IP address.
Children's privacy
Brain Groove is friendly for all ages and does not knowingly collect personal information from children. Because we don't require accounts or collect personal details, the experience is the same for everyone.
Your choices
- Disable your platform's game service in your device settings to keep your scores off leaderboards. Your progress record still exists, under your device's own anonymous identifier.
- Turn off diagnostic sharing in your operating system's privacy settings.
- Delete the app to remove locally stored gameplay data from your device.
- Email us to have the data we hold about you deleted, and we'll take care of it.
Changes to this policy
This policy describes Brain Groove as it works today. If we change how the app handles data, we'll revise the date above, update our app store privacy labels to match, and for significant changes note it in the app. Continued use after an update means you accept the revised policy.
