Doo KlotskiPrivacy Policy
Updated and effective: November 11, 2026
This policy explains how the individual developer of Doo Klotski handles information in the native 2.0 version and its website. Information about earlier versions appears below.
Version and data saved on your device
This notice covers the native iOS version of Doo Klotski 2.0. It contains 480 puzzles and does not require a separate game account. Puzzle play and spending free lightbulbs already on your device work offline. Level progress, best move counts, the current board, lightbulb balance, sound and haptic settings are saved on your device.
The app also keeps local records needed to award ad rewards, use hints and prevent duplicate processing, along with verified lifetime hint ownership, the purchase date and a device identifier used to bind that ownership cache to this device. The game’s iCloud saves do not upload the lightbulb ledger or this ownership cache.
Optional iCloud saves
When you turn on iCloud saves in Settings and confirm the merge, the app automatically synchronizes progress using Apple CloudKit to save your highest unlocked level, completion status and best move count for each level in the current iCloud account’s private database. Devices using the same iCloud account can merge these records, keeping the furthest unlocked level and the lowest best move counts.
Sync processes an app-scoped iCloud user record identifier, progress records and synchronization metadata to identify the account and synchronize saves. You do not provide your Apple Account password to the developer. The current board, undo history, free lightbulb balance, sound and haptic settings are not synchronized by this feature. Lifetime purchases are restored through the App Store.
Cloud saves use your iCloud storage. You can keep playing locally while offline, signed out, out of storage or unable to reach the service. Only successfully synchronized progress can be restored on another device. Turning off automatic sync keeps existing cloud saves; deleting the app does not itself delete iCloud data. Enabling sync again may merge and upload progress still held on your device.
Purchases, verification and restoration
Unlimited Bulbs is a one-time, non-consumable App Store purchase, not a subscription. The App Store shows the applicable price before purchase. Apple handles payment. The app uses verified information provided by StoreKit, such as product and transaction identifiers, purchase dates, entitlements and revocation status, to deliver, restore and check ownership. This purchase flow does not provide the developer with your Apple Account password or full payment card details.
Ownership already verified on this device supports offline hints. After reinstalling or changing devices, connect to the internet and restore using the App Store account that made the purchase. Refunded, revoked or unverified transactions do not establish valid ownership. Restoring purchases does not restore free lightbulbs stored on another installation.
Google ads and privacy choices
The native 2.0 version uses Google AdMob for optional rewarded ads and Google’s User Messaging Platform (UMP) for advertising privacy choices. The app may refresh privacy information at startup and may preload when the SDK permits ad requests. Required privacy forms and ads are attempted after you choose to get a lightbulb. A rewarded ad earns one lightbulb after a valid reward callback is received and the reward is saved.
Google’s ad service may process IP addresses and approximate location inferred from them, device or advertising identifiers, ad views and interactions, product interactions, crash reports, performance and other diagnostics for advertising, measurement, analytics and service maintenance. UMP processes privacy choices and information needed to provide privacy messages, including coarse location, product interaction and performance data. Processing depends on the SDK, service configuration, region, system permissions and your choices.
The ad service may associate data with a device and, where the required permission is granted, use it for personalized advertising or advertising measurement under its applicable rules. Refusing personalized ads or tracking does not affect puzzle play or existing saves. Non-personalized ads can still involve data processing. Ad availability also depends on the network and service.
Managing advertising privacy and system permissions
When an ongoing privacy options entry is required, Settings shows “Advertising privacy choices” to reopen the options supplied by Google. “Privacy policy” is available in Settings and the Shop. Available choices depend on the applicable region and the messages supplied by the ad service.
Using the iOS advertising identifier for tracking requires Apple’s tracking permission. You can manage it in iOS Settings → Privacy & Security → Tracking; labels vary by system version. Advertising privacy choices and Apple’s tracking permission are separate controls.
Service providers and retention
Apple provides App Store and iCloud services. Google and applicable advertising partners handle relevant data under their own privacy notices. Processing may occur outside your country or region; see their notices for retention periods and applicable safeguards.
Local records retain your progress, balance and ownership and prevent duplicate processing. Check completed synchronization before deleting the app or its data. Manage iCloud data separately using Apple’s controls. The developer cannot directly browse your private database through the CloudKit developer console or delete all data independently processed by Google or Apple on their behalf.
Website and developer support
The website uses Firebase Hosting. Its current pages do not embed website advertising or Google Analytics. Hosting may process IP addresses, page requests and necessary logs to serve the website. App Store, Apple, Google and other external links lead to services governed by their own policies.
If you email the developer, the email address, message and attachments you provide are used to respond and handle your request. Send only information needed to investigate the issue, without passwords, full payment details or unnecessary sensitive information. Support records are retained as needed to handle requests and applicable obligations. You can request access, correction or deletion using the email below.
Your choices and privacy requests
You may leave iCloud saves off and choose not to watch ads while continuing to play offline. Deleting the app may remove local progress and free lightbulbs. System backups, synchronized iCloud data and App Store purchase records need to be managed separately. Reinstalling is not a way to recover free lightbulbs.
Send privacy questions or requests for access, correction or deletion to doodic.works@gmail.com. We will check information needed for the request and handle it within its scope, or direct you to the relevant service provider. Guardians who believe a child has sent inappropriate personal information through support can also contact this address.
Earlier versions
Earlier versions may use Unity LevelPlay / Unity Ads. This does not mean those SDKs are integrated in the native 2.0 version. If you use an earlier version, consult the Unity player privacy notice and earlier policy linked below for the relevant ad service. Save and hint behavior in older versions may differ from 2.0.
Policy changes
We will update this policy and its date when data handling changes, and provide further notice where applicable.
