Privacy Policy

Overview

You do not need an account to play. We do not operate a game server that receives your puzzle progress, settings, or purchase receipts. Core puzzle play works offline.

Information stored on your device

The game stores puzzles, gameplay progress, statistics, settings, assistance state, and Premium entitlement status locally so it can remember your choices. This game information is not sent to a Platon Sudoku server. You can remove local game data by clearing the app's storage or uninstalling the app.

Optional rewarded ads and privacy choices

Where available, you may choose to watch a rewarded ad to receive an in-game assistance use. Ads are optional. Declining, closing, or being unable to load an ad does not prevent core offline play. We request non-personalized ads.

Google Mobile Ads and Google's User Messaging Platform provide ads and applicable consent choices. Google and its service providers may process information such as your IP address, device and advertising identifiers, app interaction information, and diagnostic information for advertising, measurement, security, and fraud prevention. The app presents consent choices where required and provides an in-app way to revisit applicable privacy choices. See Google's Privacy Policy and Google's mobile ads data disclosure guidance for more information.

Purchases

Premium is an optional one-time purchase processed by Google Play or the Apple App Store, depending on your device. The relevant store handles payment and restoration. Platon Sudoku does not receive your payment-card information or send purchase receipts to its own server. The resulting entitlement status is stored locally on your device.

Children

Platon Sudoku is intended for users aged 13 and over. It is not directed to children under 13.

This website

This static website does not have a sign-in form or its own analytics script. Cloudflare hosts the site and may process technical request information, such as IP addresses and browser data, to deliver and secure it. See Cloudflare's Privacy Policy.

Security and retention

Local game data remains on your device until you remove it. Google, the app stores, and Cloudflare handle information they process under their own policies and retention practices.

Changes to this policy

We may update this policy when the app or website's data practices change. We will publish the updated policy here and revise the date above.
