What this site collects, what it does not, and why the answer is unusually short.
Your calculator values stay in your browser
Every calculation on this site runs locally in your browser. The dimensions, resolutions, ratios, diagonals and densities you type are never transmitted to a server, never stored, and never included in any analytics event.
Your inputs do appear in the address bar, in the query string, so that refreshing the page keeps your work and so a copied link reproduces the same result. That URL stays on your device unless you deliberately share it. If you do share one, remember it carries the values you entered.
What is not collected
- No accounts, logins or profiles.
- No saved or synced calculation history.
- No uploaded images or files — there is nowhere to upload one.
- No advertising and no advertising trackers.
- No affiliate links.
- No cookies set by this site.
- No email address is requested and there is no newsletter.
- No cross-site tracking, fingerprinting or behavioural profiling.
Analytics
No analytics is currently active on this deployment. No page-view beacon is loaded and no measurement script runs.
If analytics is enabled in future it will be Cloudflare Web Analytics, which sets no cookies, does not fingerprint visitors and does not track people across sites. Even then, calculator values would remain excluded: the site's analytics layer is built so that entered dimensions and measurements cannot be sent as event data.
Hosting
The site is served as static files by Cloudflare Pages. As with any web host, Cloudflare processes the network requests needed to deliver the page, which involves standard server-side information such as IP address and user agent. That is a property of how the web works rather than something this site collects or retains.
Local storage
This site does not write to cookies, local storage or session storage. Closing the tab leaves nothing behind beyond your browser's ordinary history.
Third-party content
There are no embedded videos, social widgets, comment systems, chat widgets, font services or content delivery networks other than the host itself. Fonts are served from this site's own domain. The content security policy permits only the resources the site actually uses.
Children
The site is a set of calculators with no accounts and no data collection, so it is equally safe to use at any age.
Changes
If what the site does ever changes, this page changes with it. It describes the implementation that is actually deployed, not a generic template.
