Privacy
The short version: no accounts, no ads, no tracking scripts, no cookies. Your saves stay in your own browser. The host keeps a standard access log for 30 days (below). The only thing a game sends is a bug report, and only when you press Send.
What we don't do
- No sign-ups and no accounts.
- No cookies.
- No ads, and no analytics or tracking scripts in the pages.
- The pages don't load anything from other companies: the code, fonts and pictures all come from this site. The one exception is a bug report you choose to send (below).
What stays in your browser
The games keep your saves, settings and progress in your browser's local storage, on this device. The homepage does the same for a few conveniences: which build the Play buttons open, whether build details are shown, the theme, the sort order, the games you starred, and the games you opened recently (the “Continue playing” row). If you install the site as an app, your browser also keeps a copy of the homepage and its pictures so it opens offline.
None of this is sent to us and we can't see it. To wipe it, clear this site's data in your browser's settings.
Bug reports
Most games have Report a bug in their menu. It opens a card first; nothing goes anywhere unless you press Send report. Then the game sends:
- your note, if you wrote one;
- a screenshot of the game's own picture (not the rest of your screen);
- the game, its build and the page address;
- your browser's details: its user agent, platform and language, screen and window size, pixel density, whether it has a touch screen, its processor core count and rough memory;
- how the game was running (graphics setting and frame rate) and its last error messages.
It goes to our bug inbox, a database run for us by Supabase. Like any server, theirs sees your IP address when the report arrives. A copy also stays on your device; if sending fails, the report waits there and goes out the next time you open that game. We use reports only to fix bugs. To have one deleted, send us the report ID the card shows after it is sent.
The microphone (packetsynth)
packetsynth, the music visualizer, can listen to your microphone, or on desktop Chrome and Edge to a browser tab you share, but only when you turn that on, and your browser asks your permission first. The sound is analysed live on your device to move the visuals. It is not recorded, stored or sent anywhere. An audio file you drop in is played from memory and never uploaded or stored. A YouTube link you paste opens on YouTube, in a new tab.
The host
The site is served through Amazon Web Services (CloudFront), and its access logs are on. Every request is logged: your IP address, your browser's user agent, the page or file asked for, the page you came from, and when. The logs are kept for 30 days and then deleted. We use them for two things: to spot and stop abuse (attacks, scrapers, hot-linking), and to count how many times each game is played.
Other sites
Links to Instagram, Discord and YouTube take you to those services, and their own privacy policies apply there.
