About this policy
Sudoku+ is an independently developed app operated under the Mitsuki Labs brand. This policy covers the iOS app and its privacy and support website at sudoku.mitsukilabs.com. It describes local game data, optional advertising and privacy choices. There is no app account or developer-operated game server.
Game data on your device
Puzzles, entries, notes, settings, times, records, hint usage and daily challenge history are stored on your device. The app does not send these game records to the developer or an analytics service. Device backups may include app data according to your Apple settings.
Google advertising and consent
The app uses Google's User Messaging Platform to update consent information when it opens. Google Mobile Ads is initialized only after the privacy checks permit ads and you choose an optional rewarded ad. Google may process IP addresses (including approximate location), device identifiers, ad interactions and diagnostic or performance information to deliver and measure ads, prevent fraud and manage consent. The app requests non-personalized ads, disables Google's publisher first-party ID and does not request App Tracking Transparency permission. Non-personalized ads are not data-free. Google's own policies describe its processing, retention and international transfers.
Your choices
You can play without watching ads. Where required by Google's consent service, Privacy choices in Settings lets you revisit advertising choices. If the privacy check fails, the app does not request a rewarded ad. Consent choices do not change your puzzle progress.
Retention and support
Local records remain until the app replaces them or you delete the app and its data. Device backups are managed separately through Apple. If you email support, the developer receives your email address and message and uses them to answer your request. Support messages are retained only as needed for support and applicable obligations. Contact the developer with privacy questions or requests about support correspondence; Google manages data it processes under its own policies.
Audience
Sudoku+ is intended for a general audience and is not specifically directed to children. It does not ask for your date of birth. Parents or guardians can contact the developer with privacy concerns. Advertising and consent settings must comply with the applicable requirements for the audience and region.
This website
The privacy and support website is hosted through OpenAI Sites and its delivery infrastructure. Hosting providers may process IP addresses, browser information, request times and technical or security logs to deliver and protect the website. The site does not add advertising, analytics scripts, contact forms or tracking cookies. Email links open your email application; a message is sent only when you choose to send it. Hosting and email providers manage their own logs and retention, and may process information outside your country. This website policy applies to Sudoku+ pages, not other Mitsuki Labs apps, which have their own policies.
Policy updates
This policy may be updated when the app or its services change. The updated date identifies the current version. Material changes will be reflected in the app and the published policy.
