Privacy policy
Last updated: October 27, 2026
Kode is designed to collect as little as possible. You do not need an account to play, and we never ask for your name, email address or any other personal details. This page explains what data is involved when you use the site.
Data saved on your device
Your game progress, streak, statistics and theme preference are stored in your browser's local storage, along with a random anonymous identifier. This data stays on your device. You can delete it at any time by clearing this site's data in your browser settings.
Analytics
We use Google Analytics to understand how the site is used — for example, how many people visit, which pages they view, and how many finish the daily puzzle. Google Analytics may set cookies to tell visitors apart; in the European Economic Area, the United Kingdom and Switzerland these analytics cookies are only used if you agree to them. We only look at aggregated statistics.
Puzzle feedback
Some players are occasionally asked to rate how hard the day's puzzle felt. If you answer, we store your rating together with the puzzle result (solved or not, number of tries, time taken) and your anonymous identifier, so we can tune puzzle difficulty. This feedback is stored with our database provider, Supabase, and is never linked to your identity.
Advertising
Kode is supported by advertising. Ads are served by our advertising partner, Mediavine, through its Journey program. Mediavine and the advertising companies it works with use cookies and similar technologies to show ads based on your visits to this and other websites, and to measure how those ads perform. Mediavine's own advertising privacy notice on this page explains what it collects and how it is used. Where the law requires it, such as in the European Economic Area and the United Kingdom, you will be asked for your consent before personalised ads are shown, and you can change your choice at any time with the privacy preferences link on the site. You can also opt out of interest-based ads from many advertising companies at www.aboutads.info.
Your choices
You can block or delete cookies and local storage through your browser settings. Kode will keep working, although your streak and stats will reset if you clear the site's data.
Children
Kode is a general-audience puzzle and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to this policy
If we change how Kode handles data, we will update this page and the date at the top.
