Privacy Policy
Last updated: November 16, 2025
This quiz game app is offered on both iOS and Android. We respect your privacy and collect only the data needed for core functionality. No login or personal account is required – the game identifies players only by a random ID. We do not collect names, emails, addresses, contacts, or any other personal identifiers. We also do not collect location data, photos, microphone access, or any sensitive information. The only data tied to a user are a unique anonymous device identifier, in-app purchase records (handled through RevenueCat), and anonymous analytics data collected through Firebase Analytics and Sentry for app improvement and crash reporting.
Information We Collect
Device ID
We generate a unique anonymous ID for each player (via RevenueCat or our backend). This lets us associate game progress and purchases with your device, but it is not linked to your personal identity.
Purchase Data
If you buy in-game coins, we use RevenueCat to process the transaction. RevenueCat's documentation confirms that it collects the user's purchase history (transaction records). We receive only a purchase receipt or status – no personal payment information. Apple processes payments through the App Store; we only get the confirmation necessary to credit your account.
Analytics and Crash Data
We use Firebase Analytics and Sentry to collect anonymous usage data and crash reports. This includes app usage statistics (screen views, session duration), device information (OS version, device model), and error logs when the app crashes. This data is collected anonymously and helps us improve app performance and fix bugs. We do not collect any personally identifiable information through these services, and we do not use this data for advertising purposes.
How We Use Your Information
Game Functionality
We use the device ID to manage game sessions (matchmaking, scores, etc.).
Purchases
We use purchase data solely to grant you coins or subscriptions. RevenueCat validates the purchase and notifies us so we can credit your account. We do not use purchase data for marketing or analytics.
Security and Improvements
We may use minimal data (like device ID) to prevent fraud or enforce game rules. We may also review aggregated, non-identifying data to improve app performance. We do not sell or share your information with any advertisers or data brokers. All data use is strictly for the app's functionality and compliance.
Third-Party Services
We use only essential third-party services to operate the app:
RevenueCat (In-App Purchases)
We rely on RevenueCat to handle all in-app purchase transactions. RevenueCat processes your purchase data (purchase history and status) in an anonymous way. They do not collect any personal information from you – only transaction metadata.
Apple App Store
Apple processes credit/debit card or Apple ID payments for any purchases. We do not receive your payment details, only confirmation of the purchase.
Our Backend (Supabase)
We use a server (Supabase) to store minimal game data. The only user-related data stored is the anonymous device ID. No other personal data is stored on our servers.
Firebase Analytics
We use Firebase Analytics (provided by Google) to collect anonymous usage statistics. Firebase Analytics tracks app events, screen views, session duration, and basic device information (OS version, device model, country). This data is anonymized and aggregated, helping us understand how users interact with the app and improve the user experience. Firebase does not collect personal information. You can learn more at Firebase Privacy Policy.
Sentry (Error Tracking)
We use Sentry to monitor app crashes and errors. When the app encounters an error or crashes, Sentry collects technical information such as error messages, stack traces, device type, OS version, and app version. This data helps us identify and fix bugs quickly. Sentry does not collect any personal user information. You can learn more at Sentry Privacy Policy.
No Advertising
We do not integrate any advertising networks or use any data for advertising purposes. We do not sell or share your information with advertisers.
Data Retention and Deletion
We retain your device ID and purchase records only as long as necessary for the app to function (e.g., to remember your coins and game progress). We do not keep your data longer than needed. While the app does not include an in-app "Delete Account" button, we comply with privacy guidelines for data deletion. As Apple's guidelines state, even "guest" or automatically-generated accounts must be deletable. Therefore, you may request deletion of your data at any time. If you want us to erase your information (device ID and purchase records), please contact our support (see below). We will promptly delete your data from our systems upon request.
Children's Privacy
Our app is not directed at children under 13. We do not knowingly collect personal information from anyone under 13. If a parent or guardian believes we have collected personal data from a child under 13, they may contact us to have that information deleted. Upon such notification, we will delete any information we have about that child.
Policy Updates
We may update this Privacy Policy from time to time as our app evolves. We will post any changes on this page with a new "Last Updated" date. Your continued use of the app after changes means you accept the updated policy.
Contact Us
If you have any questions, concerns, or requests (including data deletion), please contact our support team at help@knowusbetter.app. We will respond promptly to address your privacy requests and ensure your data is handled according to this policy.
