Pandoku Privacy Policy

Last updated: November 6, 2026

This policy explains how Pandoku, the free Sudoku game for iOS and Android made by the Kurotomo team, handles your information. The short version: Pandoku does not collect any personal data.

1. Who we are

Pandoku is published by Kurotomo, a StoicWare product (stoicware.com), based in New Brunswick, Canada. In this policy, "we" and "us" refer to StoicWare.

You can contact us at support@kurotomo.com.

2. The data we collect: none

Pandoku does not collect personal data, and so it does not sell or share any. Specifically, Pandoku has:

  • No accounts and no sign-in.
  • No advertising.
  • No analytics and no tracking, inside the app or across other apps and websites.
  • No third-party SDKs that collect data.
  • No network requests to play: puzzles are created and checked on your device.

3. What stays on your device

Your game progress, your statistics and your settings (such as theme and language) are stored only on your device, in the app's local storage. They are never sent to us or to anyone else.

This data is deleted when you uninstall the app. You can also reset your statistics and your settings at any time from inside the app.

4. App updates

Pandoku can download updates to its code and content over the air, through Expo's EAS Update service, so fixes reach you without waiting for a new store release. These downloads contain no personal data about you.

To deliver an update, the update server receives the standard technical information that comes with any internet request, such as your IP address, your device's platform and the app version. It is used only to deliver the right update; we do not use it to identify you or to track you.

5. Links to our website

Links inside the app (to kurotomo.com) open in your device's browser. Once you are on the website, its own privacy policy applies: https://kurotomo.com/en/privacy.

6. Children

Pandoku is not directed to children under 13. It does not collect data from anyone, including children.

7. Your choices

Since we hold no personal data about you, there is nothing for us to access, correct or delete. Everything Pandoku keeps is on your device and under your control: reset it from the app or uninstall the app to erase it.

8. Changes to this policy

If this policy changes, we will update this page and the "last updated" date at the top.
