PRIVACY INFORMATION

Your calculations
stay in your browser.

Paperroll is a free calculator hosted on Cloudflare Pages. Updated 11 October 2026.

Calculator inputs

Measurements, labels, quantities and quotes are processed in this browser page. The calculator does not send these input values to an application server, create an account or save a project in a database or browser storage. Refreshing or closing the page clears your entries.

Downloads and printing

Downloading creates a plan file on your device. Printing uses your browser and selected printer. Neither sends the plan to Paperroll. Your device and chosen printer or file-sharing service control the saved output.

Hosting and visit measurement

Cloudflare delivers and protects the website and can process ordinary request information, including IP addresses, URLs, browser details and request times. Its operational processing is separate from the calculator.

When enabled, Cloudflare Web Analytics measures visits, page views, referring pages, device/browser information and page performance using a JavaScript beacon. It does not use cookies, local storage or browser fingerprints for this measurement. The beacon does not include the calculator's field values. Cloudflare receives a visitor's IP address as part of ordinary requests; its Web Analytics documentation says the analytics system discards it after determining the closest data centre and does not retain it in the analytics database or logs. This statement does not cover separate hosting or security logs.

See Cloudflare's privacy policy and Web Analytics documentation. Browser blocking, regional exclusions and reporting delay can affect measurement.

Google Search and advertising

Google Search Console can report aggregate search impressions, clicks and indexing status when the site is verified. Verification metadata does not install an advertising or visitor tracking script. The publisher tag and ads.txt record identify a proposed AdSense account but do not load ads or establish approval. Ads are currently off. Before advertising is introduced, this notice and any required consent arrangements will be updated.

Contact messages

Email sent to paperroll.cytoplast640@aleeas.com is processed by SimpleLogin and forwarded to the owner's email provider. A message includes the sender's email address, contents and ordinary email metadata. These are used to handle enquiries, corrections and privacy requests; avoid sending unnecessary sensitive information. See SimpleLogin's privacy policy. There is no embedded contact form.

Other websites have their own privacy practices. Calculator input values are not attached to external links. For questions about this notice, use the contact address.
