Privacy policy
You can play every game on this site without an account and without telling us who you are. This page explains the little data that is involved.
Who we are
This site, sudoko-online.com, is run by Lunar Interactive Arts Ltd, a company registered in England and Wales. For anything about this policy, email support@sudoko-online.com.
What is stored in your browser
To make the game work, the site saves a few things in your browser's local storage. They stay on your device and are never sent to us.
- the puzzle you are playing, so you can close the page and carry on later
- your chosen level, board theme and music track
- your own records: games played, games solved and best times
You can delete all of it at any time by clearing this site's data in your browser settings.
Analytics
We use Google Analytics and Cloudflare Web Analytics to understand how many people visit, which pages they read and whether the site works well on their devices. These services receive information such as the pages you view, your browser and device type, and an approximate location based on your IP address. Cloudflare Web Analytics does not use cookies. Google Analytics does, and in the European Economic Area, the United Kingdom and Switzerland it only sets them after you agree.
Advertising
The site may show adverts from Google AdSense. Google and its partners can use cookies to show ads based on your earlier visits to this and other websites. If you are in the European Economic Area, the United Kingdom or Switzerland, you will be asked for consent first, and you can change your choice at any time from the privacy link in the consent message.
You can turn off personalised advertising in Google's Ads Settings, and learn more about how Google uses data on its page "How Google uses information from sites or apps that use our services".
Hosting
The site is hosted by Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses to deliver pages and protect the site against attacks.
Children
The games are suitable for all ages, but the site is not aimed at children under 13 and we do not knowingly collect information about them. Adverts shown to people who have not given consent are not personalised.
Your rights
Depending on where you live, you may have the right to ask what data is held about you, to have it corrected or deleted, and to object to its use. Because we do not hold accounts or personal profiles, most requests are best made to Google or Cloudflare directly. We are happy to help. Write to support@sudoko-online.com.
Changes to this policy
If we change how the site uses data, we will update this page and the date at the top.
