Privacy Policy

Sudokufeud · Last updated: 23 October 2026

This privacy policy explains how The Coding Cookie ("we", "us") collects, uses and protects information when you play Sudokufeud (the "app") on Android or iOS. By using the app you agree to this policy.

1. Who is responsible

The Coding Cookie, Denmark, is the data controller for the app. Contact: thecodingcookie@gmail.com

2. Information we collect

• Account information: a player ID, the username you choose and, if you sign in with Google Play Games, Apple or an email account, the identifier from that service (and your email address if you create an email account). We never see your Google or Apple password.
• Game data: your rating, wins, losses, win streaks, solved puzzles, best times, hints, diamonds, themes and other items, and your daily rewards.
• Purchases: which in-app products you bought and a purchase receipt, so we can deliver them. Payments are handled entirely by Google Play or the App Store – we never receive your card or bank details.
• Usage data: anonymous game events such as when a session starts, how long matchmaking takes and how a match ends, used to improve the game.
• Device and advertising data: device type, operating system, app version, IP address and the advertising ID of your device (used by our advertising partner, see section 4).

3. How we use the information

• To run the game: create your account, match you with other players, show leaderboards and keep your progress.
• To deliver purchases and rewards.
• To show ads in the free version of the game.
• To fix bugs, prevent cheating and improve the game.
• To send reminders on your device (for example about your daily reward). These are scheduled locally on your device and can be turned off in Settings or in your phone's settings.

Legal bases (GDPR): performance of our agreement with you (running the game and delivering purchases), our legitimate interest (security, improving the game) and your consent (personalised ads).

4. Services we use

We share information only with the service providers needed to run the app:

• Microsoft PlayFab – player accounts, game data, leaderboards and purchases. Privacy statement
• Photon (Exit Games) – real-time multiplayer connection. Privacy policy
• Google AdMob – ads. AdMob may use your advertising ID and IP address to show and measure ads. How Google uses data
• Google Play Games Services / Apple – sign-in.
• Google Play Billing / Apple App Store – in-app purchases.

We do not sell your personal information.

5. Ads and your consent

In the EEA, the UK and Switzerland we ask for your consent before personalised ads are shown. You can change your choice at any time under Settings → Ad privacy in the app. If you do not consent, you may still see non-personalised ads. You can also reset or limit your advertising ID in your phone's settings. Buying "No Ads" removes ads from the game.

6. How long we keep data

We keep your account and game data for as long as your account exists. If you ask us to delete your account, we delete your personal data within 30 days, unless we must keep purchase records by law.

7. Your rights

You have the right to access, correct, delete or receive a copy of your data, and to object to or restrict its use. To delete your account or make any request, email thecodingcookie@gmail.com with your username. You can also complain to the Danish Data Protection Agency (Datatilsynet).

8. Children

Sudokufeud is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.

9. Security and transfers

Data is encrypted in transit. Some of our service providers may process data outside the EU; in that case they use safeguards approved by the European Commission, such as Standard Contractual Clauses.

10. Changes

We may update this policy. The latest version is always available on this page, with the date at the top.
