Data Safety

App: Sudoku Dozen 12x12,9x9,16x16

Developer: Rewertyn

Last updated: May 7, 2026

This Data Safety section applies to all versions of the game currently distributed through Google Play, including older versions that may contain advertising features.

Data Collection

The game may collect limited data for app functionality, purchases, analytics, crash reporting, diagnostics, and, in older versions, advertising.

• Approximate location: May be collected or inferred by analytics or advertising SDKs, for example from IP address or general device/network information.
• Purchase history: Used to process in-app purchases, subscriptions, restore purchases, unlock premium Sudoku packs, and validate entitlements.
• App interactions: May include gameplay events, screen views, shop interactions, purchase flow events, restore actions, and feature usage.
• Other app activity: May include game progress events, puzzle completion, hint usage, economy events, achievements, leaderboard-related local activity, and daily challenge activity.
• Crash logs: Collected to diagnose crashes and stability problems.
• Diagnostics: May include app version, build number, Unity version, platform, device model, operating system version, network reachability, initialization state, and technical error categories.
• Other app performance data: May include startup performance, IAP initialization state, store product fetch results, and technical app performance information.
• Device or other identifiers: May include app instance identifiers, Firebase installation identifiers, Crashlytics installation identifiers, Android advertising ID in older ad-supported versions, and other SDK-generated identifiers.

Advertising in Older Versions

Older versions of the game may include advertising SDKs. These SDKs may collect or process device identifiers, advertising identifiers, approximate location, ad interactions, app interactions, diagnostics, and performance data for ad delivery, frequency capping, fraud prevention, analytics, and advertising measurement.

Newer versions of the game may disable ads logically in the app code, but because older versions may still be distributed or installed, advertising-related data practices are included here for transparency.

In-App Purchases and Subscriptions

The game uses Google Play Billing and Unity In-App Purchasing to process in-app purchases, subscriptions, and purchase restoration. Purchases may include hint packs, premium Sudoku packs, and subscriptions that temporarily unlock premium content while active.

Payment processing is handled by Google Play. The game does not collect or store credit card numbers, debit card numbers, bank account numbers, or full payment details.

Analytics and Crash Reporting

The game may use Firebase Analytics to understand app usage and improve gameplay, store flow, economy balance, and technical reliability. The game may use Firebase Crashlytics to collect crash reports, non-fatal errors, diagnostics, and stability information.

Analytics and crash reporting are designed to avoid sensitive data. The game does not intentionally send raw purchase receipts, raw purchase tokens, raw order IDs, email addresses, payment details, or full store billing payloads to analytics, crash reporting, or debug logs.

Data Sharing

Data may be processed by service providers and SDK providers used by the game, including Google Play Billing, Firebase, Unity services, and advertising providers used in older versions of the game.

Advertising-related data from older versions may be shared with advertising partners for ad delivery, ad measurement, fraud prevention, and related advertising purposes.

The game does not sell personal information directly.

Data Security

Data transmitted from the game is encrypted in transit where supported by the relevant platform and SDK providers, including Google Play, Firebase, Unity, and advertising SDKs.

Data Not Collected by the Game

The game does not intentionally collect the following data:

• Name
• Email address
• Phone number
• Home address
• Contacts
• Calendar events
• SMS or MMS messages
• Photos or videos
• Audio recordings
• Files or documents
• Precise GPS location
• Health or fitness data
• Credit card, debit card, or bank account numbers

Purpose of Data Use

• App functionality: Saving progress, restoring purchases, unlocking premium content, managing subscriptions, achievements, leaderboard data, daily challenges, and in-game economy.
• Analytics: Understanding gameplay, store usage, purchase flow, app performance, and feature usage.
• Crash reporting and diagnostics: Detecting crashes, errors, IAP problems, startup issues, and technical problems.
• Advertising or marketing: Used only in older ad-supported versions for ad delivery, ad measurement, fraud prevention, and ad-related diagnostics.
• Fraud prevention and security: Purchase validation, duplicate transaction detection, entitlement checks, and abuse prevention.

Data Deletion Requests

Users may request deletion of data associated with the game by contacting the developer:

Some data may be retained where required for legal, security, fraud prevention, accounting, purchase restoration, or platform compliance reasons.

Children's Privacy

The game is intended for a general audience. The game does not knowingly collect personal information such as names, email addresses, phone numbers, contacts, photos, or precise location from children.

Changes to This Data Safety Information

This Data Safety information may be updated when the game, SDKs, analytics, crash reporting, purchases, advertising configuration, or legal requirements change.
