Privacy

Kintsugi Sudoku

Effective 6 November 2026

We do not run any servers, do not have accounts, and never see your game progress. From version 1.1 the game shows ads from Unity Ads, which is the only part of the app that shares data with a third party. This page explains what that means.

What the app stores

Your game progress (levels, gold, statistics, streaks, settings and any puzzle in progress) is saved only on your device using standard iOS storage. It never leaves your device and is not sent to us or to anyone else.

What the app does not do

• No accounts or sign-in.
• Your puzzles and progress are never sent anywhere.
• No access to your contacts, photos, location, camera or microphone.

Ads

Ads are served by Unity Ads. Unity may receive your device's advertising identifier (only if you allow tracking), IP address, device type and settings, app version, and how you interact with ads, and handles it under its own privacy policy: unity.com/legal/game-player-and-app-user-privacy-policy.

iOS asks before the app can track you, and you can change your answer at any time in Settings › Privacy & Security › Tracking. Without tracking, ads are still shown but are not personalised. In the EU, the UK and Switzerland, only non-personalised ads are shown.

To tell an ad blocker from an ordinary connection problem, the app sometimes checks whether it can reach our website and Unity's servers. No personal information is sent, and we keep no record of it.

Purchases

Gold and other in-app purchases are processed by Apple through the App Store. We never see your payment details. The app only receives a confirmation that a purchase succeeded, which it uses to add the gold to your device.

Children

The game is for a general audience and is not directed at children under 13. We do not knowingly collect information from children.

Deleting your data

Use "Erase all progress" in the app's settings, or delete the app, to remove everything it has stored on your device. To ask about data held by Unity, see its privacy policy above.
