Privacy Policy

Flatbias — Last updated: August 7, 2026

This Privacy Policy describes how Reckona Inc. ("we") handles information in the Flatbias mobile application (the "App") and on this website.

Information we collect

• Purchase information. Subscriptions are processed by Apple (App Store) or Google (Google Play). We do not receive your payment details. Entitlement status is stored on your device.
• Game progress. Your puzzle progress and settings are stored locally on your device. We do not upload them to our servers, and we cannot restore them for you.
• Usage analytics. The App uses Google Analytics for Firebase to understand which puzzles are played and where players get stuck. The events we send are limited to: a puzzle was opened, a puzzle was cleared (with the polyhedron type, its grid size, and how many times you tapped Verify), and the subscription screen was viewed. Alongside these events, Google collects an app instance identifier, device model, operating system version, language, and an approximate location derived from the IP address (country or region level). We do not set a user identifier and do not send anything that identifies you personally.
• Crash diagnostics. The App uses Firebase Crashlytics. When the App crashes or misbehaves, it sends a stack trace, device model, operating system version, App version, an anonymous installation identifier, and the time of the event, so that we can fix the bug.
• Advertising data. The App shows ads served by Google AdMob for users without a subscription. AdMob may collect device identifiers and usage data to serve and measure ads. On iOS, tracking for personalized ads occurs only with your permission via App Tracking Transparency. Where required, a consent prompt (Google UMP) is shown, and you may opt for non-personalized ads. See Google's Privacy Policy.

Your choices

• Personalized ads. On iOS, decline the App Tracking Transparency prompt, or turn off Settings → Privacy & Security → Tracking. On Android, use Settings → Google → Ads to delete or opt out of the advertising ID. Where a consent prompt is shown, you may choose non-personalized ads.
• Analytics and crash reporting. These are on by default and the App has no in-app switch for them. Deleting the App stops any further collection. On iOS, Apple's advertising identifier (IDFA) is used only if you allow tracking in the App Tracking Transparency prompt.

What we do not do

• We do not require an account and do not collect your name, email address, or contacts.
• We do not sell your personal information.
• We do not collect precise (GPS) location.

Third-party services

The App uses the following third-party services, which process data as described in their own policies: Apple App Store / StoreKit, Google Play Billing, Google AdMob (including the User Messaging Platform), Google Analytics for Firebase, and Firebase Crashlytics. Data handled by the Google services above is processed under Google's Privacy Policy.
