1. What we collect

We collect and store no personal information ourselves. There is no sign-up, no login and no account. The app does include an advertising SDK (Unity Ads), which processes the data below to serve ads (see section 3).

• Advertising identifier (GAID), IP address and device information — processed by Unity Ads for ad delivery and fraud prevention.
• There is no analytics, crash-reporting or attribution SDK in the app.
• Puzzles are generated and solved entirely on your device. The app uses the internet for checking Google Play purchases, loading ads and sending the anonymous usage events below.
• Anonymous usage events — the app sends a small, fixed set of anonymous events to a server we operate (first launch, whether the purchase screen was shown, purchase started / completed / restored, whether an optional watch-an-ad-for-a-hint offer was shown, tapped or rewarded, an interstitial ad being shown, a loaded ad expiring before it could be shown (ad format only), the number of each level you clear when you move on to the next one, and whether the app was opened again on day 1 / day 7). These events carry only a random install identifier generated by the app — no advertising ID, no device identifier, no name, no board, moves or time, and none of your content. We use them solely to understand which features are used. Raw events are deleted within 3 months and kept only as aggregate counts.
• Ad check before ads start — before turning ads on, the app sends our server one request containing only the app's name, so that automated test devices (such as Google Play pre-launch testing) do not load real ads. The server uses the connection's IP address only for that check and does not store it; it keeps only a daily count per app.
• Feedback you choose to send — only if you use “Tell us anything” in the app, we receive the category you picked, the text you typed (up to 1,000 characters), the app version, your device language, the screen or level you were on, and a random install identifier generated by the app. There is no name, email, account or advertising ID field, and email addresses or phone numbers typed into the message are masked before it is stored. Your IP address is not stored. We use feedback only to fix bugs and improve the game; it is not shared with third parties or used for advertising. Sending feedback is optional. Messages are kept on our server (Cloudflare) and deleted within 12 months.

2. Where your data lives

Data	Purpose	Stored
Current level and the levels you cleared	Chapter map and resuming play	On your device
Best move count per level	Showing your record	On your device
Puzzles cleared today and your daily streak	Daily goal and streak display	On your device
Board style selection	Showing the board the way you chose	On your device
Whether a purchase is owned	Unlocking what you bought	On your device · your Google Play account
Anonymous usage events (random install ID only)	Understanding which features are used	Our server — raw events up to 3 months, then aggregate counts only

Everything except the anonymous usage events stays on your device. There is no cloud sync.

Data retention

• On your device (level progress, best move counts, daily streak, board style, purchase status, privacy choice) — kept until you uninstall the app. Uninstalling deletes all of it. We have no copy.
• Anonymous usage events — stored on our server for up to 3 months, then deleted; only aggregate counts with no install identifier are kept after that.
• Ad check request — the connection's IP address is used only for the check and is not stored; we keep only a daily count per app with no identifier.
• Feedback you send from inside the app (if you choose to send any: your message, its category, app version, language, the screen or level you were on, and the random install identifier) — stored on our server for up to 12 months, then deleted.
• Advertising data processed by Unity LevelPlay, Unity Ads and the mediation partners in section 3 is retained by those providers under their own policies, linked there.
• Purchases — payment records are kept by Google Play under Google's own retention rules; we store no payment details.
• We keep no other user data.

3. Third-party services

Google Play Billing — if you make an in-app purchase, Google handles the payment and the app only checks whether you own the item. We never see your payment details. Google's handling is covered by the Google Privacy Policy.

Unity LevelPlay & Unity Ads (Unity Technologies / ironSource) — to serve interstitial and rewarded ads via mediation, it collects and uses the advertising identifier (GAID), IP address, device information (model, OS version, language, etc.) and ad-interaction data, which may be passed to advertising partners during ad bidding. Unity's handling is covered by the Unity Privacy Policy, and you can opt out of personalized ads via the information icon shown on ads.

Ad mediation partners — ads are selected through Unity LevelPlay mediation, which runs a real-time auction among the networks below. Each network's SDK is included in the app and, when it takes part in an auction, may process the advertising identifier (GAID), IP address (used to estimate an approximate region), device information, ad-interaction data and SDK diagnostic/crash information for ad delivery, measurement and fraud prevention. Each partner's handling is covered by its own policy:

4. International transfers

Data listed in section 3 may be processed on Unity Technologies servers abroad (e.g. the United States) as part of ad delivery. The anonymous usage events in section 1 are processed on Cloudflare infrastructure, which may be located abroad; they contain no personal data.

5. Advertising and tracking

• This app shows interstitial and rewarded ads. There are no banner ads.
• A one-time in-app purchase — Remove Ads, or Puzzle Lab, which includes it — turns ads off. Once Google Play confirms either one, no more ads are shown and the app no longer starts any advertising SDK.
• You can reset or delete your advertising ID at any time in your device settings.
• Europe (EEA), the UK and Switzerland — before any advertising SDK starts, we ask for your consent through the InMobi Choice consent tool (IAB TCF v2.2). If you decline, or close the dialog without finishing it, no advertising SDK is initialised. Your choice is stored on your device and you can reopen it at any time under Settings → Privacy choices to change or withdraw it.

6. Children

This app is for a general audience and is not directed to children under 13.

7. Your rights

• Deletion — uninstalling the app removes all data on your device.
• Restore purchases — you can restore your purchases from Settings at any time.
• Questions and requests — write to the address below.
