Privacy Policy
Last updated: September 6, 2026
App: Puzzle Garden
Developer: Mikhail Kostin
1. Overview
Puzzle Garden is an ad-free picture puzzle game designed for children ages 3–7 and their families. We designed the app to work without accounts, advertising, behavioral tracking, or user-generated content. We do not ask children or adults to provide a name, email address, photo, audio recording, or precise location.
2. Information stored on your device
The app stores preferences and puzzle progress locally on the device, including language and gameplay settings, completed puzzles, completion counts, selected difficulty, and completion times. This information is not sent to us. You can remove it by clearing the app’s data or uninstalling the app.
3. Purchases and subscriptions
Optional subscriptions and one-time purchases unlock additional puzzle content. A one-time purchase is charged once and does not automatically renew. Apple App Store or Google Play processes the purchase and payment. We do not receive your payment-card details or store-account credentials.
We use RevenueCat to display the paywall, validate and restore purchases, manage access to purchased content, and provide subscription management. To perform these functions, RevenueCat and the applicable app store may process an anonymous app-user identifier, product and transaction identifiers, purchase receipts or tokens, purchase and subscription status, transaction dates, device and operating-system information, locale, currency, network information such as an IP address, and the last time the app contacted the service.
When a parent opens a paywall, the app may also send RevenueCat non-personal context indicating where the paywall was opened and which bundled puzzle was selected. The app does not send RevenueCat names, email addresses, advertising identifiers, precise location, contacts, photos, recordings, or a custom account identifier. Automatic device-identifier collection and RevenueCat diagnostics are disabled in the app.
4. Third-party services
Other than the app stores, RevenueCat for purchase and subscription functions, and Firebase Crashlytics for crash diagnostics, Puzzle Garden does not include third-party behavioral analytics, attribution, advertising, or cross-app tracking SDKs. We do not sell personal information or share it with advertisers or data brokers.
We use Firebase Crashlytics, provided by Google, solely to identify crashes, diagnose technical problems, maintain security and stability, and improve the app’s operation. Crashlytics automatically processes crash reports, exception names and messages, stack traces, relevant application state, crash time, app identifier and version, device model and operating-system information, and random app-installation and session identifiers. We do not set a Crashlytics user ID or custom attributes, and we do not intentionally attach names, email addresses, advertising identifiers, precise location, contacts, photos, recordings, purchase information, gameplay progress, or custom account identifiers to crash reports. Firebase Analytics is not included in the app, so Crashlytics does not receive Analytics breadcrumb logs. Crashlytics information is not used for advertising, behavioral profiling, or tracking across apps or services.
5. Children’s privacy and parental gate
Puzzle Garden does not provide accounts, social features, messaging, camera or microphone access, location access, or advertising. Purchase and subscription screens and purchase-management features are located behind a parental gate. If you believe information has been processed in a way that is inconsistent with this policy, please contact us.
6. Security, retention, and deletion
Purchase-related data is transmitted using encryption and retained by Apple, Google, and RevenueCat according to their policies and legal obligations. We do not maintain a separate database of children’s gameplay or personal information. To request access to or deletion of data associated with a purchase, email us using the address below. We may need information from the purchase platform to identify the anonymous purchase or subscription record.
Crashlytics information is encrypted in transit and at rest. Firebase generally keeps crash stack traces and associated installation identifiers for 90 days before beginning the process of removing them from live and backup systems.
7. Your choices and rights
Depending on where you live, you may have rights to access, correct, delete, restrict, or object to processing of personal information. A parent or guardian may exercise these rights on behalf of a child by contacting us. You may restore an eligible one-time purchase and manage or cancel a subscription through your Apple App Store or Google Play account.
