Overview
Sudobu is a roguelike sudoku experience available on mobile and web. We show advertising to keep the core game free and offer an optional $7.99 upgrade that removes ads. This page summarizes how we collect, use, and share information when you play.
Data we collect
We collect limited information needed to support gameplay and improve performance, including device identifiers, gameplay events (such as level progression, timer completions, and joker usage), crash logs, and coarse location (city-level) for analytics. We do not collect puzzle solutions, text input unrelated to gameplay, or precise GPS coordinates.
Advertising partners
Sudobu uses third-party ad networks to deliver contextual and interest-based ads. These partners may access your advertising ID, approximate location, and interaction data to personalize content and measure effectiveness. You can opt out of personalized ads through your device settings. When you purchase the ad removal upgrade, we stop requesting ads for your account or device.
Purchases
Ad removal is a one-time $7.99 purchase managed through the platform's billing provider (such as the App Store or Google Play). We receive a confirmation token but never handle your full payment details. Billing providers may share anonymized purchase confirmations for record-keeping and fraud prevention.
Analytics
We rely on privacy-focused analytics tools to monitor app stability, level balance, and feature performance. Data is aggregated whenever possible. We use retention controls to delete raw analytics data within 24 months.
Your choices
You may opt out of personalized advertising through system-level controls, request deletion of analytics identifiers by contacting us, or decline to grant optional permissions. Removing ads reduces data shared with ad partners because no ad requests are made after purchase.
Children
Sudobu is not directed to children under 13. If you believe a child has provided us with personal information, contact us so we can delete it.

For privacy questions, requests, or appeals, email fatihdonmezbusiness@outlook.com. We respond within 30 days and prioritize urgent concerns.
