Brick Duo is a handheld brick game for iPhone and iPad. This policy explains what data the app collects, why, and how you can delete it.
On iOS, this app is subject to Apple's Standard End User License Agreement (EULA). You can read it at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
By downloading or using this app, you agree to that agreement and to this policy.
Your name, email address or phone number: the app never asks for any of them.
Location, contacts, photos or files.
Audio. The app never turns on the microphone. The sound library inside the app also contains recording code, so iOS requires a microphone permission text, but the app never asks for it and never records.
The app signs you in with Game Center through Google Firebase Authentication. From Game Center it receives your player ID and your Game Center nickname.
If you are not signed in to Game Center, the app creates an anonymous account with a random ID instead. It is linked to Game Center later if you sign in.
The account keeps your scores and settings when you reinstall the app or change phone.
In Google Cloud Firestore (servers in Singapore), for your account only: totals such as games played and time played, your best score and level for each game, the run of days you played, which shells you used, and your settings.
Device facts: platform, system version, app version and screen type, plus the country and language of your device settings. They are never looked up from your IP address.
When you beat your own best score, the key presses of that game are saved so a server can replay it and check the score before it goes on a leaderboard.
Google Firebase Analytics records how the app is used: games started and finished, scores, shells chosen, settings changed and screens opened. It does not use the Advertising Identifier (IDFA).
Google Firebase Crashlytics sends a report when the app crashes, with the device model, system version and what the app was doing.
The free version shows ads from Google AdMob: an ad you choose to watch to try a shell for 6 hours, and sometimes an ad after a game over.
AdMob may collect the Advertising Identifier (IDFA, only if you allow tracking), data about how you interact with ads, and diagnostics. In the EEA and the UK you are asked for consent first, and no ad is requested without it.
With Brick Duo Premium the app does not start AdMob at all.
Google explains how it uses advertising data at https://policies.google.com/technologies/partner-sites
The app asks for your permission through Apple's App Tracking Transparency before AdMob may use your Advertising Identifier for personalized ads. It asks the first time you open the app. If you decline, only non-personalized ads are shown. You can change this at any time in Settings, Privacy & Security, Tracking.
Brick Duo Premium is a one-time purchase through the Apple App Store. Apple handles the payment; we never receive your card details. The app asks the store whether your Apple Account owns Premium.
In the app, Settings, Player, Delete my data removes everything stored for your account: game data, settings, devices, score replays and leaderboard rows, and then the account itself.
You can also ask us by email to delete it.
Uninstalling the app removes the data kept on your device.
Brick Duo is not made for children under 13, and we do not knowingly collect personal data from them.
We may update this policy. The date at the top of the page shows the latest revision. Using the app after a change means you accept the updated policy.
