Nothing you type is transmitted. Every calculator here runs entirely in your browser.
What is collected
Nothing by me. There is no account, no advertising and no newsletter. Document sizes, page counts and image dimensions are computed locally and are not sent anywhere, because there is no server here to receive them.
One thing that is not mine
The host, Cloudflare, injects a small page-view script into every page it serves. It records that a page was loaded, from roughly where and in what browser, and it is added at their edge rather than by me — it is not in the source of this site and there is currently no way to switch it off on their free tier.
It measures visits to pages. It has no access to anything you type into a tool or any file you open, because none of that leaves your browser in the first place.
Cookies
None are set, and no preference is stored — which is why the tools open with the same defaults every time.
Fonts
The typefaces are served by Google Fonts, so your browser requests them from Google and Google therefore sees that request. Nothing you enter into a tool is part of it.
Server logs
The host keeps ordinary access logs — IP address, browser, page requested — as any web server does, used for security and diagnosing faults.
