Privacy Policy

Nestdoku is a dragon logic puzzle published by RJ Labs. This policy explains what the Android app processes.

Information stored on your device

Puzzle progress, completed levels, preferences, statistics, daily-puzzle status, purchase entitlement and feedback text are stored locally on your device. Nestdoku does not currently create user accounts or upload cloud saves.

Analytics

We use Google Firebase Analytics to understand aggregate use of features such as puzzle starts, completions and hints. Firebase may process app interactions, app-instance identifiers, approximate device information and related usage data. Firebase advertising-ID collection and ad-personalization signals are disabled. Our custom events do not include puzzle answers, feedback text, your name, email address or precise location.

Crash diagnostics

We use Firebase Crashlytics to receive crash reports and technical diagnostics, which can include device and app state at the time of a failure. Google processes Firebase data on our behalf under its applicable terms.

Advertising

After Level 1, Nestdoku may display an ad between some completed levels. Optional rewarded videos for hints or dragon reveals can be requested whenever you need them. We use Unity LevelPlay mediation and the Unity Ads network SDK. These providers may process your Android advertising identifier, IP address, device and app information, ad interactions, and approximate location inferred from network data to deliver and measure ads and prevent fraud. We do not infer consent to personalized advertising from gameplay. The one-time Remove Ads purchase stops automatic level-break ads; optional rewarded videos remain available if you choose to watch one. See Unity's Privacy Policy for details about Unity's data practices.

Purchases

The optional Remove Ads purchase uses Google Play Billing. Google processes payment and purchase information. Nestdoku checks ownership with Play, acknowledges completed purchases and stores the resulting entitlement locally. Pending purchases do not remove ads. We do not receive your payment-card details.

Children

Nestdoku is a general-audience puzzle game and does not knowingly request personal information from children.

Retention and control

You can erase locally stored game data by clearing Nestdoku storage in Android Settings or uninstalling the app. Purchases can be restored through Google Play when you reinstall with the same Play account. Analytics, crash and advertising data are retained according to the providers' applicable settings and terms.
