Privacy Policy

Effective June 2, 2026

Battle Sudoku (“the app”, “we”) is published by CrossCloudPartners. We collect the minimum data needed to provide the service. This page explains what we collect, why, how long we keep it and how to delete it.

1.What we collect

  • Account info — email address and display name you provide at sign-up.
  • Game data — saved games, statistics, friendships, match history, your preferences (palette, wallpaper, hints, undo, biometric flag).
  • User uploads — avatar and wallpaper images you choose to upload (capped at 5 custom wallpapers per account).
  • Push notification token — if you allow notifications, your device’s Apple Push Notification service (APNs) token, stored against your account so we can alert you to battle invites, friend requests and match activity. You can turn this off anytime in iOS Settings; we never use it for advertising or tracking.
  • Diagnostics — basic error logs for service stability. No advertising IDs, no IDFA, no third-party tracking SDKs.

2.What we do NOT collect

  • Contacts, calendars, or your photo library beyond the one image you pick.
  • Precise location, microphone, motion or health data.
  • Any data for advertising or profiling.

3.Why we collect it

To run your account, sync your progress across devices, match you with friends in Battle mode, send you notifications about invites and match activity (only if you allow them), render the leaderboard, and improve service stability.

4.How long we keep it

While your account is active. When you delete your account (Profile → Delete Account) every record above is removed from our database within 24 hours.

5.Third parties

We use Apple’s StoreKit for any future paid features, Apple’s Push Notification service (APNs) to deliver notifications to your device, and infrastructure providers (cloud host, database) under contract not to use data for any other purpose.

6.Children

The app is rated 4+ and suitable for all ages. We do not knowingly collect data from anyone under 13 in jurisdictions where applicable law requires parental consent.

7.Your rights

You may at any time:

  • View and edit your profile in the Profile screen.
  • Export a copy of your data by emailing support@crosscloudpartners.com.
  • Delete your entire account from Profile → Delete Account.

8.Contact

We will update this page when our practices change. The “Effective” date at the top reflects the most recent version.
