Privacy Policy

Effective date: 23 September 2026

This policy applies to One More Grid: Sudoku (Android package com.drillstudy.onemoregrid), published by 문학소정. Contact: 5516psj@gmail.com.

Game data on your device

Your puzzles, entries, pencil notes, elapsed time, hints, statistics and preferences are stored locally on your device. We do not operate an account system or a server for synchronizing this game data. The app does not request precise-location, contacts, camera or microphone permissions.

Advertising and consent

The app uses Google AdMob (Google Mobile Ads SDK) and Google's User Messaging Platform (UMP). When permitted by the consent system, the advertising SDK may request ads and process your IP address (which can indicate approximate location), device and advertising identifiers, app and advertising interactions, and diagnostic/performance information. Google uses this information for advertising, measurement and analytics, and fraud prevention. Ad requests may occur before you choose to watch an ad so an optional hint ad can be ready. Watching an ad is not required to play.

We do not include a separate analytics or account service. This does not mean the advertising SDK collects no data. Google states that SDK data is encrypted in transit. Read Google's Privacy Policy and how Google uses information from apps.

Your choices

Where applicable, the app displays Google's consent form. Use Settings → Privacy choices when the consent platform makes that entry available to review or change your choices. Declining consent or an unavailable ad does not prevent puzzle play. You can manage or reset your advertising identifier through Android settings. Offline puzzle play is supported; ads require a connection.

Retention and deletion

Local game records remain until you reset progress, clear app storage, or uninstall the app. We cannot restore deleted local records. Advertising data retention and deletion are controlled by Google under its policies and your available privacy controls; we do not have access to individual ad-user records to erase them directly. Contact us with questions or requests relating to information you have sent us.

Support messages

If you email us, we receive your email address and the information you choose to provide. We use it to answer your request and troubleshoot the app, and retain it only as needed for support and applicable obligations. Please do not send unnecessary sensitive information.

Audience and international processing

This app is intended for a general audience of teens and adults, not specifically for children under 13. Google and its service providers may process advertising information outside your country under their privacy policies and applicable safeguards.

Changes

We will update this page and its effective date when our practices change. Contact us at the email above with privacy questions.
