Privacy Policy
Effective July 20, 2026
wallpapercalculator.org is a free wallpaper calculator designed to know as little about you as possible.
What we collect
Nothing directly. There are no accounts, sign-up forms, advertising, analytics scripts or cookies set by this site. We do not receive the wall dimensions, wallpaper choices, prices or other values you enter.
What stays in your browser
Your last-used inputs and theme may be stored in your browser’s localStorage. A shareable link can also contain calculator inputs in its URL fragment. Fragment data is not sent to the server; it leaves your device only when you choose to share the link. You can remove saved values by clearing this site’s browser data.
Hosting
The site is served by Cloudflare’s network. Like other web hosts, Cloudflare processes basic connection data, including IP addresses, to deliver and protect the site. See Cloudflare’s privacy policy. We do not receive or store those infrastructure logs ourselves.
Accuracy
Roll, paste and cost results are planning estimates. Confirm measurements, product dimensions, pattern matching, batch numbers, coverage and installation instructions with the wallpaper manufacturer, retailer or a qualified installer before purchasing.
Changes
If this policy changes, the current version will be posted here with a revised effective date.
Contact
Questions about this policy may be sent to the site operator through the contact details in the domain’s public registration record.
