Privacy Policy & Terms of Service
Effective date: May 16, 2026 Last updated: May 16, 2026
These Terms of Service (“Terms”) form a binding agreement between you and Murat Kul (“we”, “us”), the developer of the Sudoku Arena Online mobile application (“the App”). By creating an account, signing in as a guest, or otherwise using the App, you agree to these Terms. If you do not agree, do not use the App.
You must be at least 13 years old (or the minimum age required in your country) to use the App. If you are between 13 and the age of majority in your jurisdiction, you may only use the App with the consent of a parent or legal guardian.
You may use the App as a guest (anonymous account) or sign in with Google or Apple. You are responsible for the security of the credentials you use to sign in. We rely on the identity provider to authenticate you; we never see your password.
You may use only one account at a time per device. You may not impersonate another person or pick a display name that is offensive, infringes on someone else’s rights, or impersonates us.
You agree not to:
We reserve the right to suspend or terminate access for any account we reasonably believe is in breach of these Terms.
The only “content” you contribute to the App is your display name and profile photo as provided by your sign-in provider. By using the App you grant us a worldwide, non-exclusive, royalty-free licence to display this content to other players inside the App for the sole purpose of running multiplayer matches and showing match history.
You can change your display name and photo at any time through your Google or Apple account.
The App, its source code, branding, artwork, generated puzzles, and every other element except your user-supplied content remain our exclusive property and are protected by copyright and trademark laws. We grant you a personal, non-transferable, revocable licence to use the App for your private, non-commercial enjoyment.
You may not redistribute the App, repackage its assets, or use them for any commercial purpose without our prior written consent.
The App relies on third-party infrastructure (Firebase, Google Cloud, Apple ID, Google Sign-In, Google AdMob). We make a reasonable effort to keep the App available, but we do not guarantee uninterrupted access. We may modify, suspend, or discontinue the App or any feature at any time, with or without notice.
The App is free to play and is supported by advertising delivered by Google AdMob. By default we request only non-personalised ads — we do not enable cross-app tracking, profile-building, or audience targeting. See section 2.4 of the Privacy Policy for what AdMob collects on our behalf.
Some optional in-game rewards (for example, an extra puzzle hint) are unlocked by watching a rewarded advertisement. Choosing to watch is always your own decision; you can decline at any time and continue playing without the bonus. Network or ad-availability conditions may occasionally make an ad unavailable; in that case the reward path is simply hidden until an ad can be served.
You agree not to attempt to defraud the advertising network — for example by repeatedly tapping ads, automating clicks, or modifying the App to spoof reward signals. We may suspend accounts we reasonably believe are engaging in such behaviour, in line with section 3.
The App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be free from errors, secure, or that any defects will be corrected.
To the fullest extent permitted by applicable law, in no event shall we be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or in connection with your use of the App, even if we have been advised of the possibility of such damages.
Our total liability to you for any claim arising out of or relating to these Terms or the App shall not exceed the greater of (a) the total amount you have paid us for the App in the twelve (12) months preceding the event giving rise to the claim, or (b) fifty Turkish Liras (₺50) (or the equivalent in your local currency).
Nothing in these Terms limits our liability for matters that cannot be limited under applicable law (such as fraud or gross negligence).
You may stop using the App at any time and delete your account from within the App (Settings → Delete account). We may terminate or suspend your access immediately, without prior notice, if you breach these Terms.
Sections that by their nature should survive termination — including intellectual property, disclaimers, limitation of liability, and governing law — will survive.
Your use of the App is also governed by our Privacy Policy, which describes what data we collect, how we use it, and your rights regarding that data.
These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-law principles. Any dispute arising out of or related to these Terms shall be subject to the exclusive jurisdiction of the Istanbul Central (Çağlayan) Courts and Enforcement Offices.
This does not limit the mandatory consumer protection rights you may have under the law of your country of residence.
We may update these Terms from time to time. The “Effective date” at the top reflects the latest version. For material changes we will post a notice in the App at least 7 days before the new Terms take effect. Continued use of the App after the new Terms take effect constitutes acceptance.
