Short version: no accounts, no analytics, and your save file never leaves your device. The pages around the games carry advertising; the games themselves do not.
Progress, unlocked characters, settings and key bindings are kept in your browser's local storage, on your own device. This is not sent anywhere and cannot be read by this site's operator or by anyone else. Clearing your browser data for this site deletes it permanently.
The pages around the games — this one, the front page, the write-ups and the changelog — carry advertising served by Google AdSense. The games themselves carry no advertising and load nothing from an advertiser. Once a game has started, it makes no outside requests at all.
Google, as a third-party vendor, uses cookies to serve those ads. Google's
use of advertising cookies lets it and its partners serve ads based on your
visit to this and other sites. You can opt out of personalised advertising in
Google's Ads Settings, at google.com/settings/ads. You can also
opt out of third-party vendors' use of cookies for personalised advertising at
aboutads.info. Blocking cookies in your browser works too, and
nothing on this site breaks if you do.
We do not receive, and cannot see, anything Google collects. No data from this site is passed to Google beyond the ordinary request your browser makes when it loads the ad.
The chat board and the report page carry no advertising.
Like almost every web server, this one keeps an access log of requests it serves. Each entry contains the IP address the request came from, the time, the page requested, and the browser's user agent string. It is used to keep the site running and to see the scale of abusive traffic — the site is scanned constantly by automated tools looking for vulnerabilities, and those logs are how that is spotted. The logs are not used to build a profile of anyone, are not shared with anyone, and are rotated away in the normal course of running the server.
Two things on these pages come from Google: the typeface, from Google Fonts,
and the advertising described above. Both mean your browser makes a request to
a Google domain — fonts.googleapis.com, fonts.gstatic.com
and pagead2.googlesyndication.com — and Google receives your IP
address as part of it, as it would for any resource loaded from another domain.
Nothing else on this site is loaded from a third party, and the games make no outside requests once they have loaded — no fonts, no ads, no analytics.
These games are suitable for a general audience and collect no personal information from anyone, of any age.
If this ever changes, this page will be updated before the change goes live, and the change will appear in the changelog. That is what happened with advertising: it was added on 4 September 2026, and this page was rewritten the same day.
