The short version: anything you open, type, or generate in any tool or game on this site never leaves your computer. There is no backend, no upload, and no account. We cannot read your data.
localStorage: each tool and game on this site stores its own settings and records here — your chosen theme and interface language (shared site-wide), which tools you've opened recently (so the tools menu can show a "recently used" list), which tool or game you opened last (only once you have ticked "Default launch page" yourself in the tools menu, so that launching the installed app from your home screen returns you to that page; unticking it clears the stored page immediately), whether the editor's sidebar and pane are open, the raffle wheel's entrant and prize lists, local best scores for Track the Ball and Number Grid. All of it stays on your own device; we cannot read it.IndexedDB (editor only): a handle to the folder you granted access to, so you don't have to hunt for the path again after a reload. It is an opaque browser reference, not file content.You can clear any of the above at any time via your browser's site-data settings, or revoke file system access in site permissions.
None at present. The Markdown parser and the monospace font the editor needs are embedded in the file itself — nothing is loaded from a CDN or a font service, and the site pages load no external resources either. Body text uses the fonts already on your computer, so nothing is downloaded for that.
So apart from Cloudflare (next section), no third party learns your IP address just because you opened this site.
⚠️ This was not true before 2026-08-12: marked.js was loaded from cdnjs and the typefaces from Google Fonts, and both services saw your IP. Everything is now self-contained.
We keep no access logs of our own. The site is served through Cloudflare, which processes connection information (such as IP addresses) under its own policies to operate the service and prevent abuse.
This site serves no third-party advertising and belongs to no ad network.
The only promotional content here is a block about our own other apps (for example Birthday Candle). It is static content produced by this site itself: no cookies, no tracking, no third-party scripts, and no third party learns your IP because of it. You leave this site only when you choose to follow a store link to the App Store or Google Play.
⚠️ Before 19 September 2026 this section described Google AdSense. That was the plan at the time and was never actually enabled; we later decided not to run advertising, so this section now describes what actually happens.
This site is not directed to children under 13 and does not knowingly collect their personal information.
If this policy changes, the effective date at the top of this page is updated. Material changes are announced on the home page.
