Privacy, plainly.
No cookies. No analytics. No third-party requests. Nothing you type is sent anywhere.
What stays in your browser
All six tools run as JavaScript in the page. When you paste text, format JSON, decode Base64, or move a gradient slider, the work happens on your device. There is no request to a remote service, and no copy of your input is kept by this site.
Reloading the page clears the text areas. Closing the tab clears them too. The tools do not use cookies, session storage, IndexedDB, or any other place to save your input.
The one thing that is stored
The site keeps a single localStorage value named tools-theme. It records whether you chose the light or dark theme, so the page can open in the same appearance next time. It contains only the word light or dark. It is not used to identify you and is not shared with anyone.
Clipboard
Some tools have a copy button. When you press it, the result is written to your system clipboard through the browser's clipboard API. That action is local. The copied text is not sent to this site or to any other service.
No third parties
There are no advertising scripts, analytics libraries, social widgets, remote fonts, or tracking pixels. The site is made of static files: HTML, CSS, JavaScript, and SVG. A request for a page also requests the shared stylesheet and the favicon; that is all.
If you send an email to hello@9166188.xyz, the message is handled by your mail provider and ours in the usual way. This website does not receive or store anything from that exchange. Do not send sensitive information you would not put in an ordinary email.
Changes
If this policy changes, the date below will change. There are no accounts to notify and no mailing list to update. The simplest promise is the one on the front page: the tools work in your browser, and your input does not leave it.
