Privacy Policy
Last updated: October 24, 2026
The short version
- There are no accounts. Your name, stats and progress are saved on your device.
- Online games send your chosen player name and your answers to our game server, only to run the match.
- Purchases are handled by Google Play or the App Store. We never see your payment details.
- Free players see ads from Google AdMob. Where the law requires it (for example in Europe and some US states), you're asked for consent first, and you can change your choice at any time in the app.
- We don't sell your personal information.
Who we are
Brain Blitz is a trivia game for Android and iOS, made by an independent developer ("we", "us"). This policy covers the Brain Blitz app and this website. If you have any questions, contact us at williamworld08@gmail.com.
Information stored on your device
The following is saved on your phone or tablet and isn't sent to us (except your player name, which is sent when you play online; see below):
- The player name you type in
- Your stats (games played, accuracy, best streak)
- Your Daily Challenge progress and streak
- Your settings (sound, vibration, daily reminder) and how many online matches you've played today
Uninstalling the app or clearing its data deletes all of this.
Online multiplayer
When you play online (public matches or rooms with friends), the app connects to our game server. The server receives your player name, the room you join, and your answers and scores during the match. This is used only to run the game and show other players in the room your name and score. Match information is held only while the room exists and isn't kept afterwards.
The app also sends the server the anonymous purchase ID created by RevenueCat (see Purchases below). The server uses it only to check with RevenueCat which categories the host of a match owns, so those categories can be included. It is kept in the server's memory only while you're connected and isn't stored afterwards.
Like any internet service, our server and its hosting provider (Render) may briefly log technical information such as your IP address, to keep the service running and secure.
Choose a player name that doesn't reveal personal information: other players in your match can see it.
Purchases
Pro, the Category Pack and single categories are bought through Google Play or the Apple App Store. They process your payment under their own privacy policies; we never receive your card or payment details.
To check which purchases you own and to restore them, the app uses RevenueCat. RevenueCat receives a random, anonymous ID created by the app, your purchase records (what you bought and when) and basic device and app information (such as the app version and device type). It is not linked to your name. See RevenueCat's privacy policy.
Advertising
Free players see ads, served by Google AdMob. Brain Blitz Pro removes them. To show and measure ads, AdMob may collect information such as your device's advertising ID, IP address, approximate location, device information and how you interact with ads.
- Consent: in the European Economic Area, the UK, Switzerland and some US states, you're shown a choice before personalized ads are used. If you don't consent, you may still see non-personalized ads.
- iPhone and iPad: the app asks your permission before using your device's advertising identifier (Apple's "Allow tracking" prompt). If you choose not to allow it, you'll still see ads, but they won't be personalized using that identifier. You can change this anytime in your device's Settings under Privacy & Security > Tracking.
- Changing your choice: use Privacy settings in the app's Settings screen at any time.
- Your device settings: you can also reset or delete your advertising ID, or opt out of personalized ads, in your phone's settings.

Daily reminders
If you turn on the daily reminder, the notification is scheduled on your device. No notification token or other information is sent to us. You can turn it off in Settings or in your phone's notification settings.
Sharing your results
When you share a Daily Challenge result, you choose where it goes. The shared image or text contains your score, the challenge's date and a link to this website. The link includes the date and score so the page can show them; it doesn't identify you.
This website
This website doesn't use cookies or analytics. It is hosted by Netlify, which may log technical information such as your IP address to deliver the site. Fonts are loaded from Google Fonts, which receives your IP address when the page loads.
Children
Brain Blitz is not directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child has provided personal information through the app, contact us and we'll help remove it.
How long information is kept
- On your device: until you uninstall the app or clear its data.
- Online matches: only while the room exists.
- Purchase records: kept by Google or Apple and RevenueCat for as long as needed to provide your purchases and meet legal and tax requirements.
- Advertising data: under Google's own retention policies.
Your rights
Depending on where you live (for example, under the GDPR in Europe or privacy laws in California and other US states), you may have the right to access, correct or delete your personal information, to object to or limit how it's used, and to withdraw consent. Because Brain Blitz has no accounts, most information is on your device and in your control. For anything else, contact us and we'll help. We don't sell your personal information.
Changes to this policy
If this policy changes, we'll update it on this page and change the date at the top. Significant changes will also be mentioned in the app's release notes.
