PRIVACY · CURRENT RELEASE

Inputs and exports
under your control.

Papermass’s calculator code processes entered dimensions, grammage, physical count and any additional batch mass in your browser.

Calculator data

No paper file, document, account or upload is requested. Inputs and results are not submitted by the application to a server, analytics event or browser-storage record. Refreshing restores the example. Copy uses the clipboard when chosen; Text and CSV create local files when chosen.

Hosting and technical requests

Cloudflare Pages delivers this static website. Delivery and security can involve technical request data such as IP address, page URL, browser information and time, under Cloudflare’s policies. This describes the calculator, not a promise that public website visits produce no network records. Read Cloudflare’s privacy policy.

Advertising and analytics

This release does not load advertising, third-party analytics or optional tracking scripts. Publisher identification in metadata and ads.txt is prepared for a possible later host-specific setup. It does not establish approval, active ads, consent coverage, measured visitors or earnings. The notice must reflect any later actual service activation.

Email enquiries

yardfill.helpful594@aleeas.com is an existing public forwarding alias shared with Yardfill and other portfolio tools. SimpleLogin forwards messages to the operator’s receiving mailbox. Emailing shares sender details, message content and any attachments with those email services. Include only what your enquiry needs. Read SimpleLogin’s privacy policy.

Your choices

Contact and exports are optional. For a question about an email you sent or operator-controlled records, use the same alias. Hosting and email providers handle their own processing. Notice prepared 18 October 2026.
