This site, Sudoku.lol, is created by Rauðás Hugbúnaður ehf ("Red Ace Software LLC"), a small software company in Iceland. Here we will explain what data we store and for what purpose, how we store it, how we use cookies and related technologies and how our advertising works. You can also manage your cookie settings.
Personal information
We do not store on our servers any personally identifiable data about users, such as name, location, playing habits or anything else. We have no user accounts so we simply don't have that kind of information available to us, nor do we want it.
If you email us for support we will have your email address and name in our mailbox. The email address is never used for any purpose other than to reply to your support requests and is never shared with any third parties.
Aggregate data and statistics
We collect data about gameplay, how many games were played each day and other metrics about the game. This data is stored in a database on our servers. It is not tied to individual users, we simply collect it as for example "There were 30.000 games of easy Sudoku played today", with nothing tying that back to who played those 30.000 games. The purpose of this data is simply to let us know how many people are playing and what are the most popular game modes.
Log Files
We keep log files of visits to the site. These log files include information about your IP address, the time of your visit, which page was visited and what type of browser was used.
Cookies & related technologies
We use cookies (small bits of information stored on your computer) to help us run the site. We use cookies to:
- Remember which options you have chosen for the game.
- Help us count the number of visitors to our website, i.e. a cookie is used so that you are not counted as 20 visitors if you play 20 games in one day.
- Store information about your consent of our cookie use.
The use of cookies listed above is by us, Sudoku.lol, and is necessary for the website to function properly. These are called 1st party cookies, because they are set and read only by us, not by any third parties. If you do not accept these cookies, either by not agreeing to the cookie consent form (if you're in the EU/EEA) or by disabling cookies in your browser, then you will not be able to play the games normally. Below you can read about 3rd party cookies that are used for advertising.
Cookies & 3rd Party Advertisements
We use Google and other ad companies to serve ads on our site. These ad companies will set cookies in your browser and read existing cookies that they have set before, possibly during visits to other sites. These are called 3rd party cookies, since they are from entities other than Sudoku.lol. These ad companies use this to serve you personalized ads, e.g. if you have been looking at shoes on a shopping site you might see ads for shoes here on Sudoku.lol. Below is the full list of ad companies which might set or read cookies in your browser during your use of Sudoku.lol, and a link to each company's privacy policy where they detail how they handle your data and what data they use to serve you ads.

Cookies these companies set during your visit here may be used to serve you targeted ads on other sites you visit later.

For users outside the EU/EEA, for example users in the USA, cookies will be allowed by default. Anyone, both in the EU/EEA and outside it, is free to opt out of the use of personalized ads below. You will still be shown ads, but the ad companies will not use cookies to tie you to other data and show you personalized ads. The ads you see if you opt out will be less relevant for you. Even if you opt out of personalized ads, the ad companies will still use cookies for purposes like making sure you are not shown the same ad over and over again, but this cookie will not be tied to any other data about you.
If you have configured your browser to send the Do-not-track header then we will always request non-personalized ads for you, no matter what you have chosen here on the site.
