Brainy (“the app”) is designed to respect your privacy. This policy explains what the app does — and does not — do with information.

What changed in version 1.1: Brainy now shows ads, provided by Google AdMob. Ads keep Brainy free. This means a third party (Google) receives some device and ad-interaction data. Everything about your brain workouts — your scores, streak, and history — still never leaves your device. Version 1.0 collected nothing at all.

Summary

• Your workout data stays on your device. No accounts, no sign-in, no servers of ours.
• We collect nothing ourselves. We have no analytics and no backend.
• Ads are served through Google AdMob — by Google or by third-party ad partners that bid through Google — which collect limited data for advertising. Details below.
• You stay in control. Decline tracking and ads become non-personalized. In the EEA, UK, and Switzerland you are asked for consent before any ad loads, and you can withdraw it at any time.

Information We Collect

We collect nothing. Brainy has no servers, no accounts, and no analytics of our own. We never see your data.

Advertising (Google AdMob)

Brainy displays banner ads pinned to the bottom of the Home, Statistics, and game screens, and one full-screen ad after you finish your daily workout — at most once per day. The Reaction game shows no ads at all, and there are no ads in the intro. Full-screen ads never interrupt a game.

These ads are provided by Google AdMob. To serve and measure ads, Google may process:

• Your device’s advertising identifier (IDFA), if you allow tracking
• Approximate location, estimated from your IP address (Brainy never requests precise location)
• Which ads you saw and interacted with
• Basic app-interaction, crash, and performance data used to operate and diagnose the ad SDK

Ad partners: Ads may be served by Google or by third-party ad partners (ad networks and ad exchanges) that bid through Google. Google and its ad partners use this information for ad delivery, measurement, and fraud prevention and, if you allow tracking or consent to personalized ads, for interest-based (personalized) advertising — ads based on your activity across other apps and websites. Brainy’s developer never collects, stores, or sees this information.

Google and its ad partners handle this data under their own privacy policies. In the EEA, UK, and Switzerland, the list of ad partners is shown in the consent dialog. Google’s policies:
