Privacy

• No analytics. No visitor tracking, no measurement scripts, no pixels.
• No cookies set by the site. The pages set none, for any purpose.
• No accounts, newsletter or comments. There is nothing to sign up for or log into.
• No third-party embeds. Fonts, styles, scripts and images are served locally with the site; no CDN fonts, no embedded players, no social widgets.
• Hosting request logs. The hosting and delivery infrastructure may process an IP address, requested URL, browser identifier and timestamp in ordinary server logs. The site adds no analytics identifier to those requests and does not combine the logs with calculator inputs or an account profile. Retention is set by the hosting and delivery providers for their operational and security purposes; this site keeps no separate copy.

Every calculator runs entirely in your browser. The figures you enter are used for the calculation in front of you and are not transmitted to this site or anyone else. Records are numbered from 001 while the page remains open; the counter and the record disappear when the page is closed or reloaded. Printing a worksheet uses your device’s own print dialogue and stays on your device.

The contact form sends the name, reply email address, selected topic and message entered by the visitor to [email protected]. The website keeps no separate database copy. The message is used only to answer or manage the enquiry and remains in the domain mailbox only as long as needed for that purpose and routine mailbox administration. Do not send confidential job files, passwords, payment details or special-category personal data. The form uses a hidden spam field, a minimum completion time and a short hashed-IP rate-limit record; the temporary rate-limit record expires after about 15 minutes and does not contain the message or email address.

The Weld Fab is the publisher and contact point for this website. Privacy and data requests can be sent through the form or directly to [email protected].

Source citations link to their publishers — HSE and TWI pages listed on the source register. Following such a link takes you to that publisher’s site under that publisher’s own privacy arrangements, which this sheet cannot speak for. Other ordinary external links likewise contain no visitor identifier or calculator input; the destination site’s own privacy arrangements apply after following one.

Any change to the facts above — however small — will be made on this sheet with a new revision date, following the same revision discipline as every other sheet on the desk (see methodology). The revision date at the top of this page is the date this statement was last substantively edited. There is no calculator or account record here to access, export or delete. Contact-form messages can be queried or deleted by writing to [email protected] or using Contact.
