Privacy Policy

3.1 Data stored locally on your device

Quizlume saves your game state on your device using the operating system's private app storage. This data never leaves your device. It is not uploaded to any server — not ours, not anyone else's. It exists solely so the game remembers your progress between sessions.

The data stored locally includes:

• Your current lives count and coin balance
• Your hint inventory
• Your all-time high score and current streak record
• Your session statistics (total questions answered, correct and incorrect counts)
• Whether you have purchased the Remove Ads upgrade
• Which cosmetic themes (Neon, Galaxy) you have unlocked
• Which question categories you have seen

You can delete all of this at any time by uninstalling the app. There is no account to delete, no server to contact, and no request to submit. Uninstalling is all it takes.

3.2 Data you send to us directly

Quizlume does not require you to create an account, register, or provide any personal information to play. The only scenario in which we would receive personal data from you is if you contact us voluntarily — for example by emailing [email protected] for support. In that case we receive your email address and the content of your message, and we use it solely to respond to you.

3.3 Data we do not collect

To be explicit:

• We do not collect your name, email address, phone number, or any identifier unless you contact us directly.
• We do not access your location — not precise, not approximate, not at any time.
• We do not collect your device's advertising identifier. The Android Advertising ID (GAID) permission is not declared in our app's manifest. Apple's Identifier for Advertisers (IDFA) is disabled in our iOS configuration.
• We do not access your camera, microphone, photos, or any files on your device.
• We do not read your contacts or any other app's data.
• We do not track what you do across other apps or websites.
• We do not collect health data, financial data, or biometric data of any kind.

Google AdMob

Platform: Android and iOS

Purpose: Serving advertisements (banner, interstitial, and rewarded video ads) within the game.

Because we operate in strict child-directed mode (explained fully in Section 5), the advertising ID is replaced with a string of zeros and no behavioural or interest-based data is used. In child-directed mode, AdMob may process the following minimal technical signals: the app's package name and version, your device's general type and operating system version, and an IP address that Google uses to infer approximate country for geographic ad targeting. Precise location is not derived or retained.

Privacy policy: https://policies.google.com/privacy

Google Play Billing

Platform: Android only

Purpose: Processing in-app purchases on Android.

When you initiate a purchase, the Google Play Billing library opens Google's payment flow. Google handles the entire transaction — your payment method, purchase validation, and receipt — directly. We receive only a token confirming that a valid purchase occurred, which the app uses to unlock the relevant item locally. We do not receive your payment card details, billing address, or Google account information.

Privacy policy: https://policies.google.com/privacy

Apple App Store and StoreKit

Platform: iOS only

Purpose: Processing in-app purchases on iOS, and providing the native in-app review prompt.

When you initiate a purchase, StoreKit opens Apple's payment flow. Apple handles the transaction entirely. We receive only a receipt confirming a valid purchase, which the app uses to unlock the relevant item locally. We do not receive your Apple ID, payment details, or billing information.

When you are prompted to rate Quizlume, the app uses Apple's native StoreKit review API. Any rating or review you submit goes directly to Apple. We do not receive your rating or review independently.

Privacy policy: https://www.apple.com/legal/privacy/

Google Play Services

Platform: Android only

Purpose: Core Android platform services required for app distribution and runtime functionality.

Privacy policy: https://policies.google.com/privacy

5.1 How ads are configured

Every ad request that Quizlume sends to Google AdMob is configured with the following flags, hardcoded at the application level. These are not toggles that can be changed remotely. They are built into every version of the app.

5.2 Types of ads displayed

• Banner ads: Small persistent ads displayed on certain non-gameplay screens (for example, the main menu and results screen). Not shown during active quiz gameplay.
• Interstitial ads: Full-screen ads shown between completed quiz rounds, not during questions.
• Rewarded ads: Optional ads that you can choose to watch in exchange for in-game rewards such as extra lives or hints. These are always player-initiated — we never force a rewarded ad.

5.3 Removing ads

Purchasing the Remove Ads upgrade permanently disables all banner ads and all interstitial ads for your device. Rewarded ads remain available after this purchase because they are voluntary and player-initiated. You can simply choose not to watch them.

5.4 Your opt-out options

Because all ads in Quizlume are already served without personalisation or behavioural targeting, there is nothing additional to opt out of. However, if you wish to further limit ad-related data at the device level:

• Android: Go to Settings → Google → Ads → "Delete advertising ID".
• iOS: Go to Settings → Privacy & Security → Tracking → disable "Allow Apps to Request to Track". You can also go to Settings → Privacy & Security → Apple Advertising → disable "Personalised Ads".
• Google's ad settings: You can review and manage Google's ad personalisation settings at https://myadcenter.google.com.

6.1 Available purchases

Consumable items (single-use; can be purchased multiple times):

• 3 Extra Lives
• 10 Extra Lives
• 5 Hints
• Starter Pack (a bundle of extra lives and hints for new players)

Non-consumable items (purchased once; permanently unlocked):

• Remove Ads — permanently disables banner and interstitial ads
• Neon Theme — cosmetic UI skin
• Galaxy Theme — cosmetic UI skin

6.2 How purchases are processed

All transactions are handled entirely by your platform's app store. On Android, purchases go through Google Play Billing. On iOS, purchases go through Apple's App Store and StoreKit. We never handle your payment information. We never see your credit card number, bank details, billing address, or any details of your payment method. We receive only a confirmation token from the platform that a valid purchase occurred, which the app uses to unlock the purchased item on your device.

6.3 Parental gate

Before the in-game store opens and before any in-app purchase can be initiated, Quizlume presents a parental gate — a simple challenge that a young child is unlikely to solve by accident.

Parents and guardians can also restrict all in-app purchases at the platform level:

• Android: Google Play → Profile icon → Settings → Family → Parental controls
• iOS: Settings → Screen Time → Content & Privacy Restrictions → iTunes & App Store Purchases → set "In-app Purchases" to "Don't Allow"

6.4 Restoring purchases (iOS)

Apple's App Store allows you to restore non-consumable purchases if you reinstall the app or switch to a new device. Tap "Restore Purchases" in the in-game store. The app will contact Apple's servers to verify your purchase history and re-unlock any items you previously bought. We do not store your purchase history — the verification happens entirely between your device and Apple.

8.1 COPPA (United States)

The Children's Online Privacy Protection Act (COPPA) requires operators of apps directed to children under 13 to protect their privacy carefully. Quizlume is designed for all ages, and we treat every player as if they could be a child. Our COPPA compliance is structural — built into the app itself, not just this policy.

• No data collection: We do not collect any personal information from any player, including children. There is nothing to obtain parental consent for, because we collect nothing.
• No advertising ID: The AD_ID permission is not in our Android manifest. No advertising identifier is collected from children or anyone else.
• Child-directed ad treatment: All ads are tagged with TAG_FOR_CHILD_DIRECTED_TREATMENT = TRUE at the app level.
• Certified ad SDK: Google AdMob is a Google Play Families self-certified ads SDK, meaning Google has verified it meets child-safety requirements for use in family apps.
• Parental gate before purchases: A parental gate prevents children from initiating purchases without a parent's awareness.
• No social features: Quizlume has no chat, no user-generated content, no public profiles, and no way for children to share personal information within the app.

8.2 Google Play Families Policy

Quizlume is configured to meet Google's Families Policy requirements, including exclusive use of self-certified ad SDKs, prohibition on advertising identifier transmission, and G-rated ad content restrictions.

8.3 Apple App Store children's guidelines

Quizlume complies with Apple's App Store Review Guidelines for apps that may be used by children, including the requirement for a privacy policy, the prohibition on behavioural advertising, and the parental gate requirement before any purchase or external link.

8.4 If you are a parent with a concern

Because Quizlume does not collect data from children, there is no personal data of your child held by us to request, review, or delete. However, if you have any concern at all about your child's privacy in relation to this app, please contact us at [email protected]. We will respond promptly and take your concern seriously.

9.1 What this means for you

Because we do not collect personal data from players, we have no personal data about you on any server. Your game save data is on your own device. GDPR rights of access, correction, erasure, portability, and objection are therefore inherently satisfied — there is nothing we hold to act upon.

9.2 AdMob and GDPR

All ad requests include TAG_FOR_UNDER_AGE_OF_CONSENT = TRUE, which instructs Google to serve non-personalised ads only and to apply GDPR-K protections universally. Google processes the minimal technical information described in Section 4 under its own legal basis and GDPR compliance framework.

9.3 Your right to complain

If you have a concern about how your data is handled and you are in the EU or EEA, you have the right to lodge a complaint with your national data protection authority. A full list of EU supervisory authorities is available at https://edpb.europa.eu.
