Privacy Notice

If you choose to join the Academy leaderboard, ChessIQ may display the following information publicly inside the app:

• Nickname
• Country or region
• Score
• Title

This public display is used for global and country-based leaderboard views.

When the app registers or updates an Academy leaderboard profile, ChessIQ may send the following data to QILA Modus backend services:

• Nickname
• Country or region
• Score
• Title
• Update timestamp
• Anonymous Firebase user ID

The anonymous Firebase user ID is used to manage ownership of a leaderboard entry and related backend checks.

When the app redeems a promo code, claims backend-backed rewards, or fulfills purchase-related economy delivery, ChessIQ may send or store the following data in private backend records:

• Redeemed promo code
• Claim timestamp
• Anonymous Firebase user ID
• Academy nickname, title, and the country or region already selected during Academy setup and attached to that anonymous Firebase user ID, if available
• Promo reward details needed to fulfill the redemption
• Product identifiers, purchase delivery fingerprints, or equivalent fulfillment markers needed to grant coins or permanent unlocks without duplicating delivery
• Economy state and reward-tracking records needed to enforce cooldowns, one-time rewards, and similar backend-controlled rules

These private backend records are used to prevent duplicate claims, deliver purchases and rewards correctly, and help QILA Modus review operational issues. They are not shown publicly in the leaderboard.

Where this notice refers to country or region in promo claim records, it means only the country or region the user selected during Academy setup. It is not inferred from IP address, device location, or similar location signals.

For Academy leaderboard participation, ChessIQ does not ask you to enter:

• Email address
• Real name
• Precise location

ChessIQ does not currently present a separate in-app advertising consent form. Leaderboard setup is separate from any platform or ad-partner permission handling.

Backend services and infrastructure providers may process standard network metadata, such as IP address, as part of normal request handling and security operations.

ChessIQ does not show this network metadata on the public leaderboard, and it is not requested from you as part of the Academy profile form.

This network metadata handling does not mean ChessIQ accesses device GPS or other device-location services.

ChessIQ may provision an anonymous Firebase Authentication account on the device when backend-backed features are used.

That anonymous Firebase user ID helps ChessIQ own and update leaderboard profiles, redeem promo codes where applicable, call authenticated backend features for economy or purchase fulfillment, and support profile deletion or identity-rotation flows where the app needs them.

ChessIQ does not require you to create a traditional account with an email address or password to use these anonymous backend-backed features.

ChessIQ offers in-app purchases through the platform store on your device, such as Apple App Store or Google Play.

When you start, complete, restore, or fail a purchase, ChessIQ and the platform store may process product identifiers, purchase state, restore state, transaction data, verification data, and local entitlement records needed to fulfill the purchase correctly without duplicate grants.

QILA Modus does not ask you to enter payment card details directly into ChessIQ. Payment credentials are handled by the platform store provider.

ChessIQ uses Firebase Realtime Database and Cloud Functions for selected backend-backed features.

These services may be used to process or store data needed for Academy leaderboard registration, updates, moderation, and deletion, promo code redemption and reward fulfillment, economy-backed reward claims, purchase fulfillment, cooldown enforcement, and date or timing checks used by live or daily content paths.

The app may keep some related state only on your device and may keep other state in backend records when that is necessary to make a networked feature work reliably.

ChessIQ may display interstitial and rewarded ads to support the app.

ChessIQ does not currently present a dedicated in-app advertising consent or withdrawal screen.

Depending on your platform, region, and Google AdMob behavior, ads may be served using contextual, non-personalized, or other platform-limited signals.

ChessIQ does not currently request App Tracking Transparency permission on iOS.

The exact advertising experience may depend on your platform, app version, and active ad partner setup.

At the time of this notice, ChessIQ uses only Google AdMob to serve ads.

QILA Modus has not yet activated mediation or additional ad network partners in the shipped app. If that changes, this notice will be updated to identify the active partners before or when those integrations go live.

When identifier-based or personalized advertising signals are available, Google AdMob and its providers may process data such as:

• Advertising identifier such as IDFA on iOS or the Android advertising ID or similar platform identifier
• IP address and approximate location
• Device model, OS version, language, and app interaction signals
• Ad impressions, clicks, diagnostics, and fraud-prevention signals

These signals are generally collected directly by the advertising partner SDK. QILA Modus does not use the ChessIQ leaderboard database to store your advertising identifier or build its own advertising profile from this data.

ChessIQ itself does not request or use device GPS or similar device-location services for ads.

ChessIQ does not currently offer a dedicated in-app screen to revisit ad-consent settings.

Ad-related permissions or identifiers may instead be controlled by your device platform or Google-provided controls, where available.

On iOS, ChessIQ does not currently present an App Tracking Transparency prompt in this version.

Changing or limiting platform-level ad identifiers affects ad personalization and related tracking. It does not by itself remove an Academy leaderboard entry.

Joining the Academy leaderboard is optional. Ads may still be shown whether or not you join the leaderboard. If you do not want to publish a nickname and country or region on the leaderboard, do not complete leaderboard profile setup. If you want to limit ad-related identifiers where your platform supports that, use the relevant device privacy settings.

If you later want to remove that Academy leaderboard identity, you can delete the Academy profile from Puzzle Academy settings. This removes the live leaderboard profile and clears the local saved Academy profile and exam history used for leaderboard participation.

Where the app offers anonymous-identity rotation as part of that flow, ChessIQ may also discard the current anonymous Firebase identity on the device and provision a fresh anonymous identity for future backend use.

Deleting an Academy leaderboard profile does not itself revoke platform-store purchases. Purchase ownership and restore behavior continue to depend on the platform store account used for those purchases.
